INKSCAPE GALLERY RC2 ------draw freely...then publish!-------
by davide|inkscapegallery 15 Jul '08

15 Jul '08

There's a lot to say about this new release...you might prefer to see it immediately..so, start from here: http://inkscapegallery.net/home I worked hard for three months to build gimpgallery (http://gimpgallery.net)and it has been recently released... So i had many ideas about how to improve inkscape gallery, i was tired and anxious at the same time... The second feeling won and i'm here to list what i've done in the last days: *The home page* It is a complete section with 4 subsections, "from the inkscape's world", "highlight on", "special sections" and "a little taste of inkscpae gallery". *4 new sections called:* fresh, mostvoted, older and popular *The "inkscape galleria"* it is a slideshow made with a jquery plugin labeled "galleria",indeed. It is quite smart and fast, just to give you another way to see what is best in inkscape gallery: images! *The user's "inkscape galleria"* Every user has his own "galleria" , just click on the link in the title block of each image content *Some layout improvements* In a big website you will always have something you fixed with a workaround, not in the best way, in other words... I've found better solutions now *The "from the inkscape world" section* It is the upper section in the home page. This was not an hard work but is important i mean, just because i'd like to work together with other inkscape based website. *The wysiwyg editor* we have a simple wysiwyg editor now. It works only for logged in users, anyway *The antispam framework* we've never had critical spam problems, you can directly publish in inkscape gallery only when logged in, indeed. we have user profiles, with an email field and i wanted to keep it safe from spam even if you need to be logged in to view the user profiles... (maybe not anymore in the future...) Anyway, the email field is protected from spam, now *The gimpgallery promo* I wanted to make you know about gimp gallery. It is another image gallery website for a free image editor and it is even more advanced compared to inkscape gallery, actually. It is freshly born and quite empty, i had to borrow some images from inkscape gallery so, if you're a gimper, go there to publish your images! This is what, i hope you to like it, there's always something to fix, to improve but that's inevitable (especially on IE) :-) i'm planning the next steps to bring inkscape gallery to the next release! See you, and keep drawing! Da. http://inkscapegallery.net

can inkscape have multiple pages, and export them to a PDF?
by Albert Cardona 15 Jul '08

15 Jul '08

Hi all, The ability to export multiple pages to a PDF would enable: - creating slide presentations - creating books Because at the moment there is no nice way to make neither slide presentations nor books in linux or bsd. Both ooimpress and scribus have very, very bad user interfaces compared to inkscape. Are there any plans on this direction? Thanks for any info.

Code cleanups
by unknown＠example.com 14 Jul '08

14 Jul '08

Hello all, I have some discussion points on code cleanup topics: 1. isnormal.h is not used anywhere in the code, can we remove it? 2. isinf.h defines a lower-case macro. Can I add to the coding standard that all #defines should be capitalized? 3. sigil spacing. Apparently most of Inkscape's code puts no space between sigil (*/&) and the following variable name. The coding style document doesn't explicitly mention this, shall I add it? So: "int const * get_int(double &johan);" Cheers, Johan

2geom gsl dependency issue
by Jon A. Cruz 14 Jul '08

14 Jul '08

Hi, With the latest 2geom update I'm unable to build on Xandros. I'm seeing ./2geom/numeric/vector.h:76: error: -1'gsl_vector_ispos' was not declared in this scope The version of libgsl0 I have there is 1.8 On Ubuntu 8.04 I have version 1.9 I think it would be good if we could keep compatibility with 1.8 at least for a while still.

[Fwd: [Tango-artists] one-canvas workflow]
by Jon A. Cruz 13 Jul '08

13 Jul '08

Here's a recent email on the Tango list discussing icon workflow. There are some interesting aspects to it, and Jakub explains the rationale for various aspects fairly well. Those include metadata "abuse", layers, gradients, shared styles, export, etc. Thought this might spur a little discussion and/or tweaking of some Inkscape aspects.

Re: [Inkscape-devel] NEW: sliders in tool controls
by Valerie 13 Jul '08

13 Jul '08

By the way, with the new sliders, you can no longer use directional keys to modify size in the Calligraphy tool. It's a pity, because they could be used for more precise value adjustments (it's hard to get a change of exactly 1 with the sliders). Also, I was hoping for keyboard shortcuts to be available to the pencil tool as well, so... Refer to my proposal for the pencil interface: http://wiki.inkscape.org/wiki/index.php/Vector-brushes I don't have problems with the integer being replaced by a slider, but I'd still like to be able to control it somewhat with keyboard shortcuts. Though I suppose the issue Could be easily side-stepped by entering a value 5 to 10 times smaller in the second field of my proposal, so that you drag the slider more freely...

Re: [Inkscape-devel] smoothing in Pencil
by Valerie 13 Jul '08

13 Jul '08

I've tried the new smoothing values! It's much better than before, so thank you very much! But I think the maximum value could be even smoother. In KOffice's Karbon14, if you choose "Curve" and "Exactness 20" for example, you get an absolutely crazing level of smoothing, i.e. you get only 2 nodes: Inkscape with 100 smooth: http://img209.imageshack.us/img209/4382/inkscapepk6.png Karbon14 with Curve exactness 20: http://img209.imageshack.us/img209/355/karbon14hw2.png Is it possible to make the slider logarithmic? This way you get your raw values, but at maximum, most curves produce only 2 nodes. A center-ish value is normal smoothing.

A problem compiling CVS

13 Jul '08

I haven't had problems compiling CVS before. This time though, 3 files seem to be giving me problems: /usr/include/poppler/Object.h extension/internal/pdfinput/svg-builder.cpp extension/internal/pdfinput/pdf-parser.cpp Nearly all of it involves the following message: warning: deprecated conversion from string constant to ‘char*’ There are too many of them, so I can't copy/paste them all, but when looking at the files they involve lines such as: error(-1, "Weird page contents"); Any idea where the error may come from? The error function perhaps?

Nodepath testing
by unknown＠example.com 13 Jul '08

13 Jul '08

Hello all, I just converted a bit of the nodetool to 2geom. Generating the knots and handles of a path is now done using 2geom path data. As it is late now, I am not 100% sure that it works 100%. Please help test to see if I broke anything. (so draw a strange path, enter nodetool and see whether everything was generated as it used to be) Thanks, Johan

easter egg star tool :)
by Alexandre Prokoudine 12 Jul '08

12 Jul '08

Hi, While documenting Inkscape we (well, Joshua) discovered that Shift + mouse drag for handles of Star tool applies different changes depending on particular handle. This is not documented neither in hotkeys cheat sheet, nor in tutorials, not in Tav's book. The middle handle gives larger values, and the periferal handles gives smaller values. This kind of switch is usually achieved by using Alt key in other tools. So, is it an easter egg? :) Alexandre

NEW: sliders in tool controls
by bulia byak 11 Jul '08

11 Jul '08

Some controls (such as the Width in Calligraphic/Tweak/Eraser tools, Tremor, Wiggle, and Mass in Calligraphic, Threshold in Paintbucket, Tolerance in Pencil) are converted from numeric editable fields into draggable sliders. As these values don't usually require much precision, this makes adjusting them much easier and faster. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Rendering(/verb) tests - comparing output files to reference files
by Jasper van de Gronde 11 Jul '08

11 Jul '08

To elaborate on what I'm working on, I currently have a tool which can execute Inkscape with some arbitrary command-line and (given what the output file is) compare the output to a set of reference files. If it finds a match it assigns the test the result belonging to that reference file, it can't find a match the test is marked "New". (It can also deal with crashes and so fort. And it can use a tool like perceptualdiff to compare the files.) Currently there are two short-comings: 1. Obviously it needs a bit more automation (you don't want to enter it all manually). Locally I'm doing this using a batch file. Since this isn't portable I'm thinking of either modifying buildtool to be able to do this, or more or less porting my batch file to Python. 2. Comparing the generated files completely automatically to the W3C reference files is practically impossible, because of font differences. This also goes for sharing reference files between different computers. I would definitely welcome some ideas for solving 2. Currently I'm thinking of a combined strategy. First of all the problem can be mitigated somewhat by using --export-id=test-body-content --export-id-only (this makes sure the revision string and the border aren't exported). This doesn't make it easier to compare the output to existing reference files, but does make it easier to share reference files between computers. Going a bit further it would be possible to eliminate all the unnecessary labels from test files. Secondly, there will always be files with text. To prevent those from being a problem I could do roughly two things: - Make sure it is relatively easy to judge the files on your own PC (using some GUI tool that lets you judge the files by clicking on a button for example). - Make some on-line tool that runs the tests and publishes the results. Both have their (dis)advantages. What would people prefer? And what are the possibilities for option 2? (That is, would it be possible to do this on the Inkscape site somewhere? Does SF have facilities for running periodic tests that I could use?)

Rendering(/verb) tests - where to put them?
by Jasper van de Gronde 11 Jul '08

11 Jul '08

I'm working on implementing rendering(/verb) tests (getting Inkscape to render SVG files and comparing them to known-good/bad reference files) and was wondering how I could best make my work available. Just putting it in some directory under the trunk does not seem like a good idea (especially at the moment). And if I were to create a separate top-level directory, should it include data files (a selection of the W3C SVG test suite a the moment)?

Icon loading now fixed
by Jon A. Cruz 11 Jul '08

11 Jul '08

I've finished up the second round if icon loading cleanup. First was to get things going with stock images http://library.gnome.org/devel/gtk/stable/gtk-Themeable-Stock- Images.html This second pass was to get the newer icon theme (added with GTK 2.6) http://library.gnome.org/devel/gtk/stable/GtkIconTheme.html That second part allows for the newer theme sets of icons to be loaded. These include the Tango icons. Probably the most important part is this now allows Inkscape to follow a standard look with other apps by using shared icons. In order to do this well we need to use standard names and standard concepts as much as possible. With my recent checkin I switched three icons over to standard, but there are still two main things to do First is to see if we can use any existing standard icons. The base spec with proposed standard icon names is at http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec- latest.html The standard icons out in existing themes, though, don't use all of those. Such themes are usually under /usr/share/icons/* or the equivalent. A few I have here are "highcolor" (the fallback default), "Human" and "Tangerine". The main second thing is to get graphic-app specific icons that are not listed in the default set figured out and assigned names. The Tango project had started this under their Art Libre set. http://tango.freedesktop.org/ArtLibreSet If anyone can take a look through there, that would be a great help. And more importantly if anyone who uses other apps such as GIMP, Krita, Blender, etc. could take a peek at what could be unified that would be a huge help.

smoothing in Pencil
by bulia byak 09 Jul '08

09 Jul '08

I have always felt that the Tolerance parameter (now renamed to Smoothing) in Pencil does not provide a wide enough range - small values look almost the same as large. So I have just shifted the range of this parameter so that 1 gives visibly rough and unsmoothed line with many nodes, while 100 gives a smooth line with few nodes. Of course this is all quite subjective, so if anyone can test it out and report if the new range works for them or not I would appreciate that. -- bulia byak Inkscape.

cairo/cmyk, next round :)
by Alexandre Prokoudine 09 Jul '08

09 Jul '08

Hi, Carl Worth has just told me they've got people who could work on CMYK support in Cairo, but they still need someone to tell them what exactly end-user applications want Cairo to do. It seems to me that we want two things: 1) optional output to CMYK PDF/PS/EPS 2) separation preview What Carl now says is: "(1) would probably be a good place to start. But I still have questions about how inkscape would like this to work. Particularly, with regard to what colorspace(s) inkscape would like to use to provide color values to cairo. What colorspace(s) would be used for blending. What to do with source colors from multiple spaces, etc." Do we want to use this chance to wet our toes in prepress waters? ;-) Alexandre

Trouble compiling a 0.46+devel release: lib2geom errors
by heathenx 05 Jul '08

05 Jul '08

I set up a virgin Ubuntu Hardy VM a couple of days ago so that I could use it as an Inkscape build environment for any of the 0.46+devel revisions. I'm only interested in compiling one of the recent SVN snapshots every once in a while just to check out some new features. I have only been able to compile revision 19107. I cannot get a more recent revision to compile due to lib2geom errors during the "make" command. I went out and found lib2geom and compiled it with cmake, make, sudo make install. No errors so I think it's good. I understand that the dev's are working on the latest and greatest stuff and probably shouldn't be distracted by people like me who have little understanding in compiling Inkscape in the first place but I feel like I'm so close. Is the lib2geom library very experimental at this time?...likely preventing me from compiling cleanly? Thank-you, heathenx

Unit tests for 2geom?
by Jasper van de Gronde 05 Jul '08

05 Jul '08

I'm converting the relevant (existing) libnr tests to 2geom as part of my GSoC project, now my question is where to put them? So far I've just put them in the 2geom directory of my local working copy and adjusted the build file in the same way as for the unit tests in the svg/ and libnr/ subdirectories for example. I imagine, however, that it might be better to add them to 2geom directly.

Color Export
by Cédric GEMY 05 Jul '08

05 Jul '08

I made somes test with scribus Team, and some troube as been revealed in CMYK handling in Inkscape export. If you have a pure black shape and export it in several format (AI, EPS, PS, PNG), only the AI export preserve the pure black. All the other result in a rich black (around C80%, M80%, 80%Y, K100%), which gives a 320 inking factor and we should not have more than 280 % in the worst case. Can someone confirm this. I tested on Mac OS, and can do the test with linuxes, but not under windows. pygmee

Discrepancies between 2geom's rotate and Inkscape's (libnr's) rotate
by Jasper van de Gronde 05 Jul '08

05 Jul '08

While converting some of Inkscape's libnr tests I found the following discrepancies between the two rotate classes: - Rotate(.234).inverse() != Rotate(-.234) in 2geom but not in libnr - Rotate(.234)*Rotate(0) != Rotate(.234) (idem.) - Rotate(0)*Rotate(.234) != Rotate(.234) (idem.) - b * Geom::Rotate::from_degrees(90.) != Geom::rot90(b) (idem.) My guess is that at least the first three have to do with how the rotation vectors are normalized. To me the most logical thing to do would be to eliminate the (in principle unnecessary) normalizations when computing the inverse of a rotation or when composing two rotations.

Changes to 2geom directory
by unknown＠example.com 04 Jul '08

04 Jul '08

Hi all, Thanks Jon for fixing the compile I apparently broke on Linux by updating 2geom, I am sorry. I just added a file saying not to change any code in Inkscape's 2geom copy. It is because we try to keep this directory a direct copy of 2geom's files. It is a lot of hassle to apply changes back and forth otherwise. If you really want to change Inkscape's 2geom code, please apply it to 2geom's SVN as well; otherwise your changes may very well be destroyed by the next update of Inkscape's 2geom copy. Another possibility is to commit your change to lib2geom first, then copy to Inkscape and commit the copy to inkscape. Thanks a lot, Johan

View option: skeleton-only mode?
by Valerie 04 Jul '08

04 Jul '08

It's great that the easy pattern-along-path functionality is already being implemented! Now is it possible to implement a view mode that turns all the LPE effects off and only show skeletons? The reasoning is the same as with outline mode: rendering speed. Some complex shapes may be quite complicated and take a long time to re-render every time, especially if one is only seeking to edit the skeleton. In fact, skeleton-only could be an option of outline mode. The biggest conflict is with Spiro lines, since users treat those as "normal" lines and not LPEs, thus probably don't want them to suddenly disappear. I'm not sure what can be done about this, save either making an exception for it (preference option?), or eventually implementing "native" Spiro splines despite them not being part of the native svg specifications.

Status update, take 2
by Maximilian Albert 03 Jul '08

03 Jul '08

Hi all, here is finally an update on my recent work. Note that this refers to the status of the project about two weeks ago. Most of what I have done in the meantime is not finished yet and, alas, was further delayed by my missing internet connection during last week and the serious build problems I have encountered afterwards (see different thread). As far as this work-in-progress is concerned, I'll outline it in a separate email to keep this one at a moderate length. Here is what's new: - A couple of new LPEs: * circle through 3 points * angle bisector * parallel to a line (it only uses start and end point of the path) * rotate copies (similar to tiled clones) * offset (in progress, see next email) - The pen context can now be put into a new internal state in which it waits for a specified number of mouse clicks, then creates a path from these clicks (by default only polylines are allowed but this is configurable) and either applies a new LPE of given type to the newly created path or passes the new path as a parameter to an existing LPE. This infrastructure is currently planned to only be used under the hood. Its full potential will become clear when we have a better UI for the new geometric LPEs. At the moment you can give it a try in two ways. Either apply the "mirror reflect" LPE to a path - it then waits for two mouse clicks which specify the mirroring line and only applies the LPE after these have occcurred. Or press Shift+C/B/A in pen tool, which activates one of the three LPEs "Circle through 3 points", "perpendicular bisector" or "angle bisector". Each of these waits for mouse clicks and then applies the LPE to a new path created from these (you will notice that you can only create polylines, which is reasonable for these kinds of constructions). - LPEPerspectivePath has a new handle to control the offset of the path (it's not ideal yet but better than tweaking the values manually). - LPEs can now choose to display or hide the original path. Boilerplate code for setting this option as well as for creating custom knotholder handles were added to lpe-skeleton.(h|cpp). - For each PointParam of a LPE, a knotholder handle is now automatically created (a separate status bar tip can be provided, otherwise the tooltip is reused). This made the clumsy "edit on-canvas" button in the LPE dialog obsolete. If you want to see it in action, "Lattice Deformation" is probably the LPE where the benefits of automatic handles are most visible. :) - Each LPE can now display custom helper paths (similar to how the original path is displayed in node context). Just like handles for PointParams, these helper paths are automatically created for PathParam parameters. Again, "Lattice Deformation" is a good illustration. It displays a (very rudimentary) grid joining the lattice points. In the course of implementing custom helper paths, the framework also was reworked to make live updating of paths faster, among other things (though this can probably still be optimized). Known bug: The helper paths are not live-updated during dragging, and sometimes old ones don't vanish. This used to work properly, but it needed to be switched off due to the "green fish problem" which occurred last week (sorry for the hassle with it, BTW). It will be sorted out soon. More soon. Cheers, Max

GSoC Unit test suite update
by Jasper van de Gronde 03 Jul '08

03 Jul '08

The utest tests are now converted to CxxTest tests and you can build all the CxxTests on Windows. To build (and execute) them on Linux you still just do "make check", to use them on Windows build the linkcxxtests target and then execute cxxtests.exe (which is put in the build directory). You should execute it from the inkscape directory, as it needs a lot of dll's, unless you have the right dll's available in your path. Unfortunately the new CxxTest tests do not build under Linux yet. (With a bit of luck this will be remedied within one or two days, I'm currently doing a test build of Inkscape with some changes to add helper/units-test.h to make check.) I also made some new tests from scratch in CxxTest format. The test file for svg-path was committed some time ago and there are some tests for svg-affine and svg-length now as well (the latter doesn't have a lot of tests yet though). The test executable generates three types of output: 1. Its progress is written to stdout 2. A log is kept in text format 3. A log is kept in xml format The last two are put in the same directory as the cxxtests executable. Finally, the results of the tests themselves: - Two of the existing CxxTest tests (AttributesTest::testAttributes and DirUtilTest::testBase) fail on my system(s). - A test converted from the utest framework also fails (BezierUtilsTest::testBezierPt1). - Some of the new tests fail, but fortunately not in ways that would cause problems (for example, the current transform writing code outputs rotations and skews as a matrix instead of a rotate or skewX/Y, not wrong, but not very consistent/user-friendly either).

Re: [Inkscape-devel] Import form openclipart
by Jakub Klawiter 02 Jul '08

02 Jul '08

Hello! :/ strange my gmail sent this message to pvt e-mail not to list probably. I'f i'm wrong excuse me for the dupe. > This is a bug on OCAL's side. We tried to find someone to fix it on > their side and we failed. It is very possible that I don't understand the real problem, but from my (user) point of view there are bug on both sides, as I wrote on previous message. Inkscape is importing *only one*, and always *only first* image uploaded to OCAL. And this is IMO a bug in Inkscape. If OCAL supports more than one version of image, and many of them can be SVG files, Inkscape should ask user which one (s)he want's to import. It is possible that somebody will upload a set called: "John Example" and inside you will find files: John Example (SVG) John Example Monochrome (SVG) John Example Manga Style (SVG) Rasterized John Example (PNG) Inkscape should ask what version of Mr. Example you want to import. You can say, ppl should not upload various version of picture into one "set". Maybe, but they probably will if they can, and IMO Inkscape and OCAL should work with this, because *software should be for users* not vice versa. Other bug in OCAL is that it can show thumbnail only if PNG file is first. Yes it is a bug in OCAL which maybe will be killed (a bug) someday. -- Pozdrawiam, Jakub.

Startup crash (perhaps related to modified CFLAGS)?
by Maximilian Albert 02 Jul '08

02 Jul '08

Hi all, for a while now I have been compiling Inkscape with empty CFLAGS/CXXFLAGS, which greatly speeds up the build. Since last week, however, Inkscape consistently crashes for me during startup. I first thought this was caused by one of the recent SVN commits, but bisecting the history I was unable to identify any malicious commit because a single revision sometimes worked and sometimes didn't. It's still strange that the problem only seems to occur with revisions that are not older than one or two weeks. I have a separate SVN checkout on my hard drive which uses unchanged CFLAGS/CXXFLAGS (which I use when I need full debugging information). This one works without problems. Has anyone else seen similar crashes in the past, perhaps related to modified CFLAGS? I'd be very glad if someone could point me to a solution because development is severely slowed down with the increased compile times, and I've already spent several days just trying to recompile Inksacpe and finding that the crash is still there. Many thanks in advance, Max P.S.: Of course I tried 'make clean' but that didn't help. :(( Backtraces are worthless, too, since they read like this: #0 0xb74db9d7 in ?? () from /usr/lib/libgdk-x11-2.0.so.0 #1 0x00000000 in ?? () (as I said, debugging symbols are stripped off in these builds)

I don't know if it helps but because the menus are rendered by the OS I can get to the font dialog, and the font preview in that dialog renders just fine.

SVGFonts UI discussion thread
by Felipe Sanches 01 Jul '08

01 Jul '08

Currently SVGFonts rendering in a helper GtkWindow is working ok for glyphs described using the path descrition ("path:d") attribute. Once we move the rendering to the canvas, arbitrary chunks of SVG will be added to the glyphs. Currently glyph kerning and missing-glyph nodes are also properly handled and rendered. I am using the helper GtkWindow because we still don't have pango+userfonts integration. So I am using cairo+userfonts directly on the GtkWindow. Once pango supports userfonts, I will remove the GtkWindows and render SVGFonts on the correct place (directly in the canvas). Since my work now depends a lot on this pango support, it has been evolving very slowly. I am thinking of doing some user interface work while we are stuck with pango. So, this thread is intended to discuss ideas and mockups on what people want to see for the SVGFonts user interface. Mental told me yesterday that it should be possible to edit glyphs on canvas directly on the rendered text in an "edit fonts" mode. I agree that this is the ideal thing to do, i.e. have things rendered in real time as much as possible. For example, when the text "Felipe" is rendered using an SVGFont and the user goes to "font edit mode", then editing the content of one of the "e" glyphs would make both "e" glyphs to be visually modified as if they were clones. That is the desired "real time" on-canvas bahaviour. But I also think that there should be an off-canvas glyph-editing user interface. There must be a dialog where the user can define the glyph-names, metadata such as font-family name and all the other font descriptors, the missing-glyph curves, and all of the glyph-kerning rules. Also, in this off-canvas UI, we could/should have helper lines indicating font metrics information such as base-line, top-line, etc. just like a font-editor would be. I also have in mind a unicode codepoint selector widget to be used for the u1 and u2 attributes in the kerning rules dialog. Please, feel free to offer new ideas or to say my ideas are crap or whatever. I am open to discussion. JucaBlues

Crash when applying patterns
by Maximilian Albert 30 Jun '08

30 Jun '08

Hi, since a short while ago, applying a pattern to a path in the fill/stroke dialog has led to a crash. I have found out that this is caused by invalid path data in share/patterns/patterns.svg which was introduced in revision 16619. Namely, there are stray minus signs (without a number following them) at two places in the code, like this: C -152.421,-34.897 -132.804,-34.567 -147.875,- L -150,-46.156 z (notice the isolated minus sign in front of the L). I committed a temporary "fix" by just inserting the value 999.999 for the missing coordinates (this makes it easy to find them in the file). Of course this messes up the patterns but I don't know the correct values for the missing coordinates. Bulia, since you committed the new patterns, could you have a look and properly correct them? BTW, were the paths created using Inkscape? In this case we should also find out why the invalid path data was produced in the first place. Max P.S.: Note that there still is another bug related to patterns which leads to a crash when you want to edit patterns using their knotholder handles. I wanted to fix it but it was shadowed by the new crash so I couldn't work on it. I hope to resolve it as soon as possible.

Import form openclipart
by Jakub Klawiter 30 Jun '08

30 Jun '08

Hello! Inkscape has great feature to import clipart from openclipart.org, but if there is more than one picture inkscape will import the first one. Same time openclipart will show thumbnail of an image only if first uploaded picture will be raster one (eg. PNG). You can check it here: http://openclipart.org/media/files/wariat/8984 there is no thumbnail but inkscape will import SVG file http://openclipart.org/media/files/jean_victor_balin/8735 there is a thumbnail of a picture but inkscape will import PNG file, while svg is still available. IMO there is a bug on both sides. Openclipart should show thumbnail if there is a raster image on any position of a set. User should not think about this. Inkscape should import any file from gallery, so if there is more than one file in set, it should: - ask which one user want's to download (IMO better) or - show all images in import window. What do you think? -- Pozdrawiam, Jakub. Milion osób dziennie pobiera Firefoksa... pobierz i Ty! www.firefox.pl

path parsing - nartbpath optimization?
by unknown＠example.com 30 Jun '08

30 Jun '08

Hi all, When parsing "M 0,0 1,0 1,1 0,1 0,0 z", the old nartbpath optimizes it and stores it like: "M 0,0 1,0 1,1 0,1 z". The 2geom path parser does not. So when writing the path back to svg, nartbpath and 2geom don't match up. What to do? Should 2geom optimize the path as well? Or should the svg writer optimize it? Or keep it the way the input was? Thanks for thoughts, Johan

SVGFonts: lot's of questions

1. "all text is output to libnr using livarot types, not using cairo" Can you explain that in more detail? I'd like to know: * what livarot types are. * how does livarot distinguish from cairo * does that mean we need to replace livarot? How to proceed? 2. "Getting text layout to use Cairo for output rather than libnr." Can you show me where does that output reside in the code? 3. [09:51:42] <^-> [JucaBlues] so, I guess, we should have in the API a way to provide pango with the metrics specified on svgfonts xml attributes [09:52:03] <^-> [JucaBlues] i mean kerning and stuff like that [09:52:15] <cyreve> yeah which, now I think of it, is exactly what gail is looking at "Finding a way to get the user font through Pango. One (ugly) possibility which comes to mind is to pretend to be sans-serif while going through Pango and then do a fudge afterwards. Gail asked to be a part of this discussion and she's more knowledgable than I am about cleaner approaches which could be taken here, so I've CCed her" I'm still feeling completely lost Juca

Hi, A recently added "3D polyhedron" extension is actually more useful than it seems at first site, because it can load arbitrary OBJ files which are basically 3D model objects. Nifty, eh? ;-) What is not so cool is that users are supposed to provide full path to an OBJ file in a text input box. Is it actually possible to hook an Open File dialog to extensions? Alexandre

Support for other than English on OS X
by Jon A. Cruz 27 Jun '08

27 Jun '08

Hi, I finally got time to test a few things about Inkscape.app building on OS X to enable languages other than English. The secret turns out that the Resources folder inside just needs an empty folder with the name of the local and ".lproj" added. For example, to add Spanish it just needs "Spanish.lproj" to be added as an empty directory. And adding an empty "sv.jproj" folder enables Swedish (as "Svenska" in the OS X International control panel). I've attached a simple hack to osx-app.sh for testing. If anyone who's successfully built an Inkscape.app for OSX could test this, that would be a big help. thanks. It's on bug 242105 https://bugs.launchpad.net/inkscape/+bug/242105

OSX native compile error

Inkscape wants to use Bitstream Vera Sans as the default font, but I don't have that installed on my system so every character becomes ugly rectangles.

quick note on "using"
by Jon A. Cruz 26 Jun '08

26 Jun '08

Hi, Just a quick little note on the use of "using namespace" and such in .h files. Please don't have "using" in .h files, since that ends up contaminating any .cpp files that include the .h. Also any that include .h's that in turn include .h's that do... ... but then we get into my personal preference to avoid #include inside of .h's when possible.

Text toolbar and controlling available options
by Valerie 25 Jun '08

25 Jun '08

If you recall, I proposed "flow into shape" on the toolbar for easier chart items, with border and alignment options, while many of you also want kerning commands in the text toolbar as well. (oh by the way, I'll have to decline on removing the "vertical layout" button from the toolbar: I'm half-Chinese, so it wouldn't surprise me if some took that removal rather badly ;) ) http://img57.imageshack.us/img57/475/textinterface3uc0.png (It's still messy for now) As you can see, even after resizing and removing unnecessary buttons, the resulting toolbar would still be ridiculously long. So basically, the ideal would be to first implement a way to control what appears in the toolbar. Options include: - ticking boxes or lists in text preferences - a button on the toolbar to add or remove buttons by ticking from a list - right click -> customize then drag and drop (like in Firefox 3) - alternatively, is it out of the question to have buttons appear on 2 rows? (with options to collapse parts)? So the big question is... which of the above is feasible and/or can be implemented most easily/fastest? This would be useful for other tools that are starting to have too many options, too. Once something like that is implemented, more options can be added, such as: - more text style elements (underline, strike-through, subscript, superscript, etc) - I was thinking offsets values for object aligns. - spellcheck options and custom layout options? - presets too On an unrelated note: text rendering happens to be pretty slow in Inkscape. This is probably due for its conversion into a deformable svg object? But some of us just want to do charts in Inkscape without fancy text effects, or do one of those tutorial picture files you see on Deviantart. When you reach a text file that size though, Inkscape starts to become Really slow. Is it possible to get a "plain text" option for all that? If I wanted to resize the text, I'd change the font size, not accidentally drag on the text box corners. There could be a toggle button between plain text and dynamic text, just like there's a toggle right now between bezier and spiro.

Tracking dependencies
by Jon A. Cruz 25 Jun '08

25 Jun '08

Hi guys, There's a side issue that's been kicking around for a while now. Inkscape doesn't really have it's dependencies explicitly listed. So things may or may not work for certain users trying to build on certain platforms, OS versions, etc. For example, I put in a patch recently that uses g_timeout_add_seconds (). In the documentation on it, the function is listed as "Since 2.14". So that bumps the requirement to have glib2 >= 2.14. However that would make things no longer work on Fedora 7 and instead bump Fedora 8 as the minimum there. Since that's only a year old, the might be a bit too soon to bump. Anyway, this highlights a need we have to be tracking what we bump and what impact it will have. This is something that even non- programmers can help with, so I've added a quick section and link to the Help Wanted wiki page: http://wiki.inkscape.org/wiki/index.php/ HelpWanted#Determining_Dependencies A first step would be if people skimmed through the glib and gtk+ docs looking for newer functions. Then adding those that are in our codebase to the "Functions Used" table on the wiki could really help: http://wiki.inkscape.org/wiki/index.php/ Tracking_Dependencies#Functions_Used Then if someone has a distro they care about, they can add it and/or fill out details for at at http://wiki.inkscape.org/wiki/index.php/Tracking_Dependencies#Distros Finally, the developers can get a handle on creeping dependencies, and perhaps add a few #ifdef's or alternate methods where needed in order to keep things sane.

SPCanvasBuf cairoified
by bulia byak 24 Jun '08

24 Jun '08

I have just committed a change which turns SPCanvasBuf from 24bpp to 32bpp (since cairo cannot handle 24bpp buffers) and adds a cairo_t member (buf->ct) that canvas items can use to draw themselves using cairo. So far, canvas bpaths, ctrllines, and ctrlquadrs are drawn with cairo; the rest of items still use direct bitflipping although they are updated for 32bpp (and I think they should stay that way, as they don't need antialiasing and cairo would be much slower for them). Everything should work and behave exactly as before, except a little faster, and except the temporary regressions outlined below. Note that this only concerns canvas items; regular objects are still rendered as before. Total cairofication has become closer but we're not there yet. Here's what you need to remember to use cairo to render a canvasitem: - In the update method, you're given an affine matrix. Remember it. - In the render method, transform your points by the remembered affine, and then subtract from it the point (buf->rect.x0, buf->rect.y0). Use the resulting coords to draw into buf->ct, then everything will be where it must be. - When setting colors using cairo_set_source_rgba, give the components in the order B, G, R, A, not R G B A. Problems and regressions: 1 For some reason, drawing the canvasbuf onto the screen using cairo is very slow. So I had to keep the old method using gdk_draw_rgb_image_dithalign, which is faster even though it involves a 32bpp->24bpp conversion because gdk can only deal with 24bpp. This is controlled by the define CANVAS_OUTPUT_VIA_CAIRO in sp-canvas.cpp; uncomment it to use the cairo output. Can any cairo guru guess what is going wrong here? 2 Cairo cannot draw over the past content of the buffer with inversion. The XOR operator does not result in inversion, or at least I couldn't figure out how. So, the text selection (Shift+arrows over) had to become semitransparent blue instead of black with inversion. Hopefully this will be possible to fix with a future version of cairo. 3 With apologies to Mac users, I had to take out the code which reverts the byte order depending on endianness, which used to fix the problem caused by our using fixed byte order (RGBA) and cairo depending on the endianness of the hardware. Now that many things draw directly into the buffer using cairo, I can no longer easily separate what is drawn with cairo and what not, so there's no endianness fix anymore and as a result the colors of canvas items on a Mac will likely be wrong. This is a temporary regression; when rendering of regular objects is also cairoified, we can restore this fix, and when the problem 1 above is fixed, this endianness fix will be no longer needed because everything will be cairo throughout. Let me know if you find any problems. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Re: [Inkscape-devel] Misc questions (dropdown menus, retrieving path info from files, LPE)
by Valerie 24 Jun '08

24 Jun '08

(Yay! :D ) Here's my take on 3) (alternatives are welcome): I can see 3 types of behavior people could want for LPE width: - absolute width: most useful for thin lines. Ex: 2 px. - % of original (%): big clipboard items. Chances are, when you copy an object you've just made for LPE, you want the object width to be more or less retained. - proportional resize: actually, isn't this what "bend path" more or less does? The object isn't stretched, it's just resized and bent. At first I was wondering how to call the last option in just two letters, but then I realized that it's best to make that a repeat option: http://img150.imageshack.us/img150/2599/lpekz5.png So, apart from the above, you have the following for units drop-down: % -- px mm etc. By the way, there should be an option for the resulting object to take on the color/fill properties of the original object instead of the current line properties. This in particular could be set as default for clipboard items: - if you copy a green leaf, you probably want it to stay green - also, if in the future you can copy complex objects with different fills and strokes for LPE, that'd allow you to retain those multiple settings Also, is it possible to implement a "skeleton" mode where all LPEs are disabled and only the skeletons are visible? The reasoning is simple: LPEs can consume a vast amount of memory. A skeleton mode would serve very much the same purpose here as the Outline mode (indeed, the outline mode itself could be made to only show skeletons and not rendered effects).

Startup slowdown caused by nr_arena_updates?
by Maximilian Albert 23 Jun '08

23 Jun '08

Hi all (and Johan in particular because it regards one of your commits), apparently rev #18921 introduced a significant slowdown in Inkscape's startup procedure (that's what git-bisect says). I'm not sure what the issue really is but after starting Inkscape, my CPU stays extremely busy for about 20 seconds or so. During that time, drawing operations and other actions respond considerably more slowly.[1] After about 20 seconds, everything seems to work as usual again, and all operations are reasonably fast. Anyone else seeing this? Here is a typical backtrace after interrupting Inkscape in gdb: #0 0x08241eb2 in Geom::D2<Geom::Bezier>::D2 () #1 0x08241ff6 in Geom::BezierCurve<1u>::BezierCurve () #2 0x082420b6 in Geom::Path::Path () #3 0x084d6ea8 in Geom::Path::operator* () #4 0x087fc9af in Geom::operator* () #5 0x084859e9 in nr_arena_shape_update () #6 0x0847cf70 in nr_arena_item_invoke_update () #7 0x0847ec8f in nr_arena_group_update () #8 0x0847cf70 in nr_arena_item_invoke_update () #9 0x0847ec8f in nr_arena_group_update () #10 0x0847cf70 in nr_arena_item_invoke_update () #11 0x0847ec8f in nr_arena_group_update () #12 0x0847cf70 in nr_arena_item_invoke_update () #13 0x0847ec8f in nr_arena_group_update () #14 0x0847cf70 in nr_arena_item_invoke_update () #15 0x084283c2 in sp_icon_doc_icon () #16 0x084291ee in load_svg_pixels () #17 0x084292f9 in prerender_icon () #18 0x08429d24 in icon_prerender_task () #19 0xb7340c91 in ?? () from /usr/lib/libglib-2.0.so.0 #20 0x00000000 in ?? () Note the several calls to nr_arena_group_update() and nr_arena_item_invoke_update(). The precise 2geom routines usually vary, but I see these two calls consistently during the slowed down phase. Hope this helps; it would be nice to have it fixed (I need to start Inkscape pretty often for testing, and this slowdown makes it quite annoying). Many thanks, Max [1] I first noticed this by drawing a star and converting it to a path (Shift+Ctrl+C) directly after startup, during which the cursor kept its hourglass state for about 15s. It doesn't seem to be related to path conversion, though.

VERSION and INKSCAPE_VERSION
by Bob Jamison 23 Jun '08

23 Jun '08

Hi, verbalshadow and I were looking at config.h and inkscape_version.h. Could we reduce our generated files by 1 and remove inkscape_version.h? It seems redundant. It only defines INKSCAPE_VERSION , rather than VERSION, and is used by aboutdialog.cpp. Can we move this to config.h like everyone else does? ^^ bob

regressions

Hi all, in the last two days: - on startup: ** (inkscape:18931): CRITICAL **: gdouble sp_document_height(SPDocument*): assertion `document->root != NULL' failed - widgets in the Gradient tool controls are all squeezed together without intervals - a green fish skeleton (!) is visible above the canvas on startup or loading any document - not an object but some stray helperpath display, likely from a broken LPE Please whoever committed stuff recently, look over your commits and fix this :) -- bulia byak Inkscape.

Configurable upper options bars?
by Valerie 22 Jun '08

22 Jun '08

I've just noticed that in Firefox you can configure the upper toolbars by right-clicking and selecting "customize." Then you can drag and drop elements wherever you want and/or drop them into a box to remove them from the bar. Will Inkscape be able to do this? As options are added to the various tools, their option bar start to become too long for computers with smaller monitors (especially small laptops), when most people won't need All the options at a time. The drop-down is an awkward workaround for many at best, and right now you can't chose the ordering either. The Firefox solution is in my opinion a rather nice one. When Inkscape's toolbars migrate to XML (was that it?), would it have the same level of configurability? If so, how long would it take, as it'd affect whether I try to come up with some GUI designs as options to an existing tool or as a separate tool (I'm not adding them to options of an existing tool if it makes the option bar twice as long as before)?

bitmap rendering is too slow
by Roberto A. Foglietta 20 Jun '08

20 Jun '08

Hi to all, I use inkscape and I am happy of it. I am writing here because I realized export bitmap function is too slow in particular when there are some object with blur option sets high. If I save the drawing in plain SVG and import it with gimp it take just few seconds instead many tents of minutes. I hope this help you to grab from gimp a more efficient algorithm which may be used to rendere the draw too which, with blurred object, is very low too. However I see that inkscape rendering is slight better than gimp's one but in many low-res application and in show-and-try-again or in view rendering such excellence are not required and takes too much time. Please leave me in CC aswering this email because I am subscribed to this m-list by digest. Cheers, -- /roberto

Cairo PDF output and pdflatex issues
by rhenwood User 20 Jun '08

20 Jun '08

Hi Folks, I'm running the Inkscape distributed with Ubuntu 8.04 [Inkscape 0.46, built Apr 7 2008] and PDFLatex included with the distribution. When I save a drawing from Inkscape as 'Cairo PDF' I am unable to include it into my document with pdflatex: PDF inclusion: Page Group detected which pdfTeX can't handle. Ignoring it. I suspect Cairo export is configured to export page groups in anticipation of multi-page Inkscape in the future.... but this is speculation on my part. What is apparent, however, is that Inkscape cannot be used as a drawing companion with pdfLatex out-of-the-box on the latest Ubuntu. This is (for me at least) a break in my workflow. Any suggestions for a workaround? cheers, richard

I won't be able to make it, but the one in the USA was very good. If anyone could make it there to have an Inkscape presence, we could get together demo art, fliers that can be printed, etc.

GTK file dialogs on Windows
by Bill Baxter 19 Jun '08

19 Jun '08

I didn't realize these new native file dialogs on Windows were going to completely replace the GTK ones. I actually find the GTK ones to be easier to use because of those handy user links you can make on the left, and because of the way incremental search works. I figured there would be something in Preferences to bring back the GTK dialog, but I couldn't find such a thing. Is it just hiding from me somewhere? --bb

Re: [Inkscape-devel] Problem compiling win32 svn-18969
by Bob Jamison 18 Jun '08

Mr Sonic, :-) Try deleting build.dep, then running buildtool again. This forces it to refresh the dependency cache, scanning the source directory again. This happens automatically when you do a clean build, but of course you don't want to do that every time. A good rule is to always do this when you do an "svn up" and see any A's or D's for .cpp files. bob -----Original Message----- >From: Docsonic <docsonic@...58...> >Sent: Jun 18, 2008 10:12 AM >To: inkscape-devel(a)lists.sourceforge.net >Subject: [Inkscape-devel] Problem compiling win32 svn-18969 > > >When I try to compile svn-18969 on WinXP I get an slew error at the linking >stage - > >Make error line 366: LINK problem: >build\libinkscape.a(sp-shape.o):sp-shape.cpp: >(.text+0x1e13): undefined reference to >`bounds_exact_transformed(std::vector<Geo >m::Path, std::allocator<Geom::Path> > const&, Geom::Matrix const&)' >build\libinkscape.a(effect.o):effect.cpp:(.text+0x76d): undefined reference >to ` >Inkscape::LivePathEffect::LPECopyRotate::LPECopyRotate(LivePathEffectObject*)' >build\libinkscape.a(effect.o):effect.cpp:(.text+0x7a3): undefined reference >to ` >Inkscape::LivePathEffect::LPEParallel::LPEParallel(LivePathEffectObject*)' >build\libinkscape.a(effect.o):effect.cpp:(.text+0x7bf): undefined reference >to ` >Inkscape::LivePathEffect::LPECircle3Pts::LPECircle3Pts(LivePathEffectObject*)' >build\libinkscape.a(effect.o):effect.cpp:(.text+0x7db): undefined reference >to ` >Inkscape::LivePathEffect::LPEAngleBisector::LPEAngleBisector(LivePathEffectObjec >t*)' >build\libinkscape.a(nr-arena-shape.o):nr-arena-shape.cpp:(.text+0x2ce0): >undefin >ed reference to `bounds_fast_transformed(std::vector<Geom::Path, >std::allocator< >Geom::Path> > const&, Geom::Matrix const&)' >build\libinkscape.a(nr-arena-shape.o):nr-arena-shape.cpp:(.text+0x2ebc): >undefin >ed reference to `bounds_fast_transformed(std::vector<Geom::Path, >std::allocator< >Geom::Path> > const&, Geom::Matrix const&)' >collect2: ld returned 1 exit status > >Any ideas? > >Thanks, > >Tony >-- >View this message in context: http://www.nabble.com/Problem-compiling-win32-svn-18969-tp17984902p17984902… >Sent from the Inkscape - Dev mailing list archive at Nabble.com. > > >------------------------------------------------------------------------- >Check out the new SourceForge.net Marketplace. >It's the best place to buy or sell services for >just about anything Open Source. >http://sourceforge.net/services/buy/index.php >_______________________________________________ >Inkscape-devel mailing list >Inkscape-devel(a)lists.sourceforge.net >https://lists.sourceforge.net/lists/listinfo/inkscape-devel

Commiting "big" .h files
by Bob Jamison 18 Jun '08

18 Jun '08

Hi again. For the last few weeks, it seems that one of the "big" .h files has been committed almost every day. I mean files like verbs.h, document.h, effects.h, etc. I call these "big" files because they are important dependencies for a large portion of all of the source .cpp and .h files. What this means, is that people are becoming cautious of performing an "svn up" for fear that it will result in an almost complete rebuild of Inkscape each and every time. I don't know of any remedy for this (odd/even days?), since all new development and bugfixing is good. But it would help if people would at least consider the implications before they commit. bob

Temporary canvas items
by Maximilian Albert 18 Jun '08

18 Jun '08

Hi all, (Johan, I'm CC'ing you because you actively worked in this area a while ago) I'd like to use the temporary canvas item machinery to display some "info" related to LPEs. This info can consist of helper paths or perhaps even text (e.g., for LPEs measuring path lengths or areas). I've played a bit with it but I think I'm not using it in the correct/recommended/ easiest way, which sometimes even results in crashes. So my questions are: - How can I create a temporary canvas item to display a helper path having a given shape? - How can I display text using this mechanism? - If I want to make either the helper path or the text permanent (i.e., convert them into a non-temporary item and save them in the document), how can I achieve this? Thanks for any help, Max

Re: [Inkscape-devel] GTK file dialogs on Windows
by Bob Jamison 18 Jun '08

18 Jun '08

Hi, all, Actually, considering that the pre-existing Gtkmm dialog is not new, but is actually compiled along with the new native dialog, I would think that the possibility of using either should be simple. But making it runtime selectable rather than compile-time selectable is the issue, I think. There need not be a GUI for it, so there is no "user disconcertion" problem. (BTW, I don't look to Mr Spolsky's site for software wisdom). If it -is- a compile time switch, then it should be according to capabilities, rather than according to platform: #ifdef WIN32 <- not settable #ifdef HAVE_NATIVE_WIN32_FILECHOOSER <-- easily settable In fact, I believe that we have had a general "style" of avoiding platform-specific switches as much as possible. bob -----Original Message----- >From: Joel Holdsworth <joel@...1709...> >Sent: Jun 18, 2008 9:15 AM >To: Bill Baxter <wbaxter@...400...> >Cc: "inkscape-devel(a)lists.sourceforge.net" <inkscape-devel(a)lists.sourceforge.net> >Subject: Re: [Inkscape-devel] GTK file dialogs on Windows > >Can I suggest you add shortcuts into your My Documents folder to link to >the places you want to go to.

I uploaded a patch to the bug tracker that enables building of CxxTest unit tests on Windows. Basically it adds a target linkcxxtests that generates an executable that performs all the tests. The relevant bug is: https://bugs.launchpad.net/inkscape/+bug/208821 There are two main points I'd like some feedback on: 1. Is the way I let buildtool generate the required .cpp files using cxxtestgen (see the compile target) acceptable? 2. Does anyone have a (big) problem with compiling (not linking) the (unit) tests as part of the normal build process? I added the cxxtest files to the normal compile target because it was easier that way (I had some problem with the dependencies if I did it differently) and because it will break the build if anyone breaks a test (which people really shouldn't do). Note that I'm only talking of compile-time problems here. As it is now the tests are not linked during in the normal link target, and they are definitely not executed. Jasper van de Gronde

l-system fern formula
by Mihaela 15 Jun '08

15 Jun '08

I'm trying to draw fern pattern using l-system, I found a formula on a website that says you get this: http://www.home.aone.net.au/~byzantium/ferns/leaf34.gif if you use this formula(s): angle 8 axiom x a=n n=o o=p p=x b=e e=h h=j j=y x=F[+A(4)]Fy y=F[-B(4)]Fx F=@1.18F@...1985... (I separated rules with ; ) But the result I got doesn't match: http://img143.imageshack.us/img143/1948/fernmt4.png Is this a bug in l-system, or are these rules wrong, or am I using the effect wrong? btw the image I got was made with order 34 as the website suggested, but it takes a long while till Inkscape calculates it (nearly 100000 nodes), I'd suggest a much lower order for testing ;)

NEW: relinking clones
by bulia byak 15 Jun '08

15 Jun '08

A new command, Relink Clone to Copied in Edit > Clone, allows you to relink any clone to a different original object without changing its other properties. Just copy (Ctrl+C) the object you want to be the new original, select any number of clones, and choose the Relink command. Now all selected clones are linked to the copied object. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

PS/EPS import proposal
by bulia byak 14 Jun '08

14 Jun '08

Would anyone object if I switch PS and EPS import from using pstoedit/skconvert to this: - convert ps to pdf with ps2pdf from Ghostscript - import pdf to Inkscape? Reasons: - Ghostscript is doubtlessly the most competent open source software for dealing with Postscript; it is cross-platform, actively updated and is much more commonly installed than anything else we've been using - our PDF importer is the best importer we have, and it works better than any third party things that claim to produce svg - for multipage postscript, we get for free a dialog for selecting the page (and later, the option to import multiple pages into one multipage SVG will only have to be coded once for PDF and work for PS at once). Testing by people in https://bugs.launchpad.net/bugs/190424 as well as my own experience tells me this route works quite well. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Hi guys, In cleaning up the autosave patch, I came across an uninitialized member variable in SPDocument (the flag for modified since last save). I cleaned up the initialization and added all the member variables I could find. However, it's possible this might unmask some other bugs or workarounds. Just wanted to give a heads-up on it.

Re: [Inkscape-devel] Proposal: stick to node or stick to segment
by Valerie 12 Jun '08

12 Jun '08

Hey, guys, Help! I'm trying to think up the interface for sticking, and the easiest would be to add a few buttons to Node edit mode to specify "stick:" you select two nodes and click the icon. Drawing a line from one stick point to another is fine too. I think there could be at least two types: stick node and stick object. Stick object is when you want the whole object to follow the other one around. Stick node only - with ability to stick handlers as well - is more used for linked fills and such. The whole object isn't moved, instead gets deformed by pulling the node in directions. There is one big problem though: does Anybody have any ideas how to make the nodes of two non-combined objects visible simultaneously for sticking? Proposals? The problem with combination, even if temporary, is that the combined objects lose their properties: a big no-no. Possibilities include: 1. Allow node-editing mode to show the nodes of multiple selected objects 2. Instead of targeting any available node, the user must first specify stick points or segments on individual objects. In a "stick" mode, all available stick points on all objects show up. This is also "cleaner" than when All the nodes show up. 3. Or same as above, except the available stick points only appear on mouse-over: you start drawing a line from the starter stick point to the destination stick point, upon drawing on the object the stick points of that object become visible. 4. A bit like above, but without needing to specify a custom stick-point: when drawing the connector, when you approach an object the nodes on said object become visible. So? Which one is acceptable? Or does anybody have completely different proposals in mind?

GSoC tech drawing project -- status report / outlook
by Maximilian Albert 12 Jun '08

12 Jun '08

Hi all, now that my recent changes are committed to trunk (which was a bit delayed because the LPE stacking forced me to rewrite some things), here is a little update on the status of my GSoC project. Caution, it's slightly lengthy! But even if you're not interested in most of it, I'd appreciate any comments on the questions/ideas mentioned (you may want to skip the first few paragraphs in this case). I started by writing three very simple LPEs for various geometric constructions. These are: circle-with-cadius, perpendicular-bisector and tangent-to-curve (in the following abbreviated CwR, PB and TtC). They were mainly chosen for the different kinds of user interaction they require so that I can use them as an indicator of what is still missing. Although LPE parameters can already be adapted using the LPE dialog, it is clear that for a user friendly interface we need knotholder handles for LPE items. I first added these in a quick-and-dirty way but it quickly became apparent that for a "correct" and more powerful solution the knotholder-related classes needed to be converted to C++. So this is what I did next (see my recent email for details). This also made it possible to add on-canvas handles for LPEs in a semi-automatic fashion similar to how parameters are added. I will put a description of how this works on the wiki soon. It works pretty well, but perhaps the mechanism can still be improved or made more elegant. Please let me know if you have any comments. Note that there already existed a PointParam parameter class for LPEs but the new handles do *not* duplicate their functionality since the latter can be used to alter _any_ kind of parameter, analogously to how handles for regular SPItems are used (e.g., with TtC there are handles to adjust the length of the tangent which is controlled by *scalar* parameters, not PointParams). Unfortunately, PointParams are currently broken due to the C++ification process but once I fix this, handles will also be added automatically for them. This will render the inconvenient "edit on canvas" button obsolete and make them much more comfortable to use (I'm looking forward to seeing the new lattice deformation in action then :)). One of the main remaining issues with handles is that we must eventually be able to simultaneously allow KnotHolders and NodePaths for LPE items. E.g., for PB and TtC it is essential to be able to edit the original path while at the same time adjusting the parameters on canvas. Currently this is not possible because an item can only have either a knotholder or a nodepath but not both. My first decent attempts to simply enable both for certain items consistently resulted in crashes. Since I'm not very familiar with the shape-editor code I'd appreciate any hints or even guidelines how this can be done. For instance, which parts of the code rely on the assumption that only one of knotholder/nodepath is active? Bulia, you said that you did some decent work in this direction. Do you have special advice how to proceed? Another simple recent change was to allow LPEs to either suppress the red helper path (which indicates the original path) or to display it permanently while the item is selected. E.g., for spiro splines it is suppressed while for PB and TtC it makes sense to know how the perpendicular bisector or the tangent are located with respect to the original curve so the helper path is displayed. BTW, I noticed a bug in my code - sometimes the helper curve does not disappear when the item is deselected. I will investigate this. What's the correct way to make the item disappear, anyway? The function remove_temporary_canvasitem() doesn't seem to work. IMO, the next big step to improve user interaction is to get rid of the "first draw a shape, then apply LPE" scheme. Most, if not all, of the planned LPEs only require very simple paths to which the LPE is applied. For example, CwR and PB only need a straight line, for a future angular bisector and circle-through-3-points we would need a path consisting of just three nodes, etc. My idea is this: Let's have a special mode in the pen and/or pencil tool which waits for a given number (say N) mouse clicks, then converts these into a polyline consiting of N nodes and (N-1) straight line segments (no curved paths are possible) and finally automatically applies a specified LPE to this polyline. This would be very similar to how the Spiro spline mode of the pen/pencil tool works now, only that arbitrary LPEs could be applied and that (optionally?) only polylines are allowed. As soon as we have a toolbar for the new geometric LPEs in place, the new "LPE mode" in the pen tool would be activated by pressing the corresponding button. Does this make sense? Any suggestions for details of the workflow? After this is done, I'm going to write the remaining planned LPEs (which I haven't done yet because I considered it favorable to have the on-canvas machinery in place in order to avoid major rewritings). This should be very quick (I already have drafts for a couple of them on my hard drive). Then I'd like to start tackling automatic toolbar integration of LPE parameters. I don't have a clear idea yet of what is needed for this so if you have any suggestions, I'd love to hear them. Johan, can you comment on this? Can I simply integrate RegisteredWidgets into existing toolbars or what kind of groundwork is needed to achieve this? Many thanks for reading thus far and for any comments you may have! Max

Is there a how to for creating integrated printer software for inkscape?

12 Jun '08

Hi... Is there a how to for creating integrated printer software for inkscape? My assumptions are that inkscape can only print to raster and / or postscript type printers. And postscript is used when plotting or cutting is how the printer works. Beyond that, are there any provisions for "plugin" software printer drivers? For instance, what happens when you want to print to an HP plotter that understands HPGL? ...thanks

buildtool on linux
by Bob Jamison 11 Jun '08

11 Jun '08

Hi all, I've been working on buildtool some more, to try to make it more generic and portable. There is a lot of work to be done, but as of yesterday, it can now build Inkscape on Linux. build-lx.xml is the build file. Buildtool has a built-in package-config reader, which makes things a LOT easier. I uploaded a build here: http://inkscape.modevia.com/btool/inkscape-0806101650-btool.7z It uses binreloc, so it can be run from anywhere on the disk. It does not include all of the special dependencies of Inkscape. We will work on that later. It will likely just copy the not-so-common .so's to the $INKSCAPE/lib dir, exactly the same as the win32 "dist" target copies dlls. bob

Win32 Gtk locale
by Bob Jamison 11 Jun '08

11 Jun '08

Hi, all. On the channel, <gal_bolle> pointed out that although Inkscape's translations strings are working correctly, Gtk's are not. Looking around, I noticed that in the win32 package, we are copying devlibs/lib/locale and not devlibs/share/locale to the package. I believe the first is for translating the tools, and the second is for translating the runtime. I made the adjustment to build.xml and uploaded a build here: http://inkscape.modevia.com/win32/Inkscape0806111651.7z Please try this out and see if the Gtk stock button names are translated. Since the file dialogs are now native, they are not a good place to look. Maybe try the "Close without saving" dialog. bob

XML cleanups
by MenTaLguY 11 Jun '08

11 Jun '08

A few months back, I'd been threatening to make some significant changes to the XML code during this release cycle, and one of them just bit us. I was hoping it would go smoother than it apparently has. The issue is this: a lot of cleanup and implementation-hiding in the XML code is blocked by the fact that many parts of the code currently create XML nodes which are not initially attached to any document. This is compounded by the fact that a great deal of code doesn't know what the relevant document is, since it was long assumed that it could be set up with a document later. So, a lot of code has to be rewritten to plumb the relevent XML document in. I added an assertion to trap any code that neglects to create nodes with a document, and am proceeding from there to rework the affected code. That was the reason for the recent "Save As" crash. I wish there were a "nicer" way to do this, but after six years I've come to the conclusion that the drastic approach is the only way to get this done. -mental

Re: [Inkscape-devel] Proposal: stick to node or stick to segment
by Valerie 11 Jun '08

11 Jun '08

By the way, while thinking about stickies, I think I've finally thought of a possible animation interface for Inkscape! :D (though really, I'm in no hurry to see it implemented, not before the Inkscape interface is more dynamic) A long, Long time ago, I tried Flash in Summer Camp, and I'll just say that I didn't like it (though I don't know how it works now). The approach I'm suggesting is that you add actions to a given object. You basically call up a (big) panel and add actions much as you would a live path effect. When you use the "edit animation" mode, you can turn on the animation "skeleton", which basically makes icons appear next to the object to show if the types of transformations applied to it that frame. From there, the most common parameters can be edited in the toolbar by clicking the action icon of choice: "From" field, "To" field, anchor points, speeds etc. Types of actions: Move, Rotate, Resize, Opacity, Color, Blur, Stick, Free Transform. People can create their own plug-in effects. The effects can collapsed so that you can easily see the list of effects on that object. The panel looks a bit like this (> is collapsed, V is open): Action: [+] Add action ----------------------------------- > "Jump:" Move | Start: [ ] | End: [] V "Swing:" Rotate Name: Swing Start: [] Offset: [] End: [] Offset: [] Add trigger: [+] Anchor point: [] Speed: [] Repeat type: [] [] Offset (clicking opens up X and Y values) [] Jitter (clicking opens up X and Y values) ----------------------------------- Major elements: 1. Start and end: Start has 2 possible types: - Date - Trigger - "End" also has duration (which basically is a "+ [value]" figure) 2. Triggers. The use of triggers is what makes time management easy in this case. You can define Absolute triggers with specific times, or you can create a new one within the object and based upon an action. Basically, in "Hang", clicking on Add Trigger will pop up a panel asking you to: - name the trigger (example: Man.StopSwing) - the condition: either as a proportion of action completed (0%, 50%, 80%, 100%), or a specific parameter (ex.: angle reached 90 degrees) >From then on, this trigger can be called upon in another object and action. This way, you can specify that as soon as one object is done with an action, the other starts another action. "Offset" can be used too (ex: an object starts moving 20 seconds before another reached the end of a movement path). I prefer this trigger-centric approach because it makes time management that much easier across multiple objects. Back when I tried that older version of flash, I had to go looking which frames were doing what. :\ Here you can just change the duration of one action, and the rest automatically falls through. Note: triggers can also be events such as MouseOver, Click, etc. 3. Anchor point. You define anchor points on an object (eventually naming them something other than "Node9011"), and this will be the point of attach of the action. Different actions can have different anchor points. "Move" also asks you to specify a path. "Stick" asks you to define a destination point on a destination object: you're sticking one point to another. 4. Parameters: for rotation, you define the rotation speed and/or amplitude, for resize you define the starting and ending sizes. If possible, jitter and offset value options can be added. Of some interest, the main parameter (rotation, resize etc) could be a custom curve. A straight curve from one value to another is a linear resize for example. But you can also make waves of decreasing amplitude, which in the case of resize/Height only, for example, makes the object look bouncy after say... falling to the ground. 5. Free transform works a bit differently than the rest. My proposed interface is this: this action is applied onto an object with -multiple- layers that count as separate frames (eventually with sub-layers, but it's the first-level layers that are counted as Frames). So you don't do the transformations within the animation file, but separately, but this should be fine as it makes your CPU life easier. The user basically creates an image, makes several copies on separate layers, makes changes to each, then imports it into the animation file. When applying free transform (or whatever it can be called), the user determines how the image morphs from one frame to another (usually the underlying skeleton moves from one position to another, the user can specify time for each frame as well as relations to trigger events) An "update" option is quite possible, so you make adjustments to the external files and see them updated directly. En error console pops up if the result is too different. :P 6. Stickies. Stickies are a very important part of this process, because it means a whole lot less of actions! Example: A man is carrying a box, puts it on a truck, and the truck drives away. Breakdown: - Add Stick action to box, so you don't have to redefine the walking. - Add Move action to man walking. - The Stick action stops when the man arrives at the end of his movement path. - Add Move action from box to truck. - Add stick action from box to truck. - Add move action to truck. The box just follows it because of the stick. This greatly simplifies things because it avoids having to duplicate paths and values (which can be a whole lot after a while) Other example: - a Linux penguin walks to a seesaw. Linux penguin jumps onto the seesaw (move action). - the seesaw rotates. Linux penguin also goes down because as we also define a "stick" action to that end of the seesaw. - when that side of the seesaw reaches ground (angle trigger), the object on the other side (a Microsoft logo), that used to be "stuck" on the object until then, gets unstuck and does an arc trajectory into a nearby trash bin. :) In the meantime you have the grass defined to swing back and forth with no conditions at all, though the penguin stepping on it may "trigger" it to flatten. 7. There should be an automatic summary timeline for each object to show trigger events and actions applied. The timeline keeps it simple, triggers only show their name upon mouse-over (though they may be different colours depending on whether they result from an action underway in this object, in another object, or from clicking something), and tiny action logos appear in the timeline (mouse-over shows the name, type, and highlighted line and triggers to show how long it lasts) Once the user is happy, he orders Inkscape to calculate the entire output, makes any adjustments necessary before re-calculating, and exports. That's it! :D I plan to make visual mock-ups, but would there be any problems with this approach? Some people are probably familiar with the Flash way of doing things (whatever it is they are doing now), but I do prefer simply saying "Let's add a simultaneous move and rotation on this or that object. It lasts This long and stops when another object reaches a certain state." Yay? Nay? Anyway, users can write up all sorts of fancy effects on their own, like the object getting cut up in all sorts of ways or leaving a temporary ghost trail while resizing. People could download those as extra effects plug-ins.

"Inkforge": Inkscape Becomes an SVG Font Editor?
by Dave Crossland 11 Jun '08

11 Jun '08

Hi, (I've blogged this at http://understandinglimited.com/2008/06/09/proposing-inkforge/) I hope I can inspire people to patch Inkscape to make it suitable for drawing type :-) SVG Fonts isn't supported much anywhere, but Chris Lilley's talk at LGM2008 has got me thinking :-) Could Inkscape become an SVG Font Editor? Designing type involves working at four scales: A. designing individual letters ("drawing letters") B. designing letters that look like they belong together ("drawing type") C. designing letters that fit together to form words ("designing metrics") D. designing letters that fit together to form paragraphs ("looking at typeset text") I think Inkscape could be good at all four of these. Inkscape already has a template "fontforge_glyph" that sets up a canvas suitable for drawing a single letter - (A) One way of making (B) possible could be through layers. SVG has "svg fonts" already, and this could work by having each glyph appear to be a layer. It would be possible to write a simple program to output an XML tree with the glyphs you want to design, and have a bunch of SVG Font templates for various common scripts. For this to really be useful though, Inkscape needs to have a new kind of layer-specific guideline. Inkscape doesn't appear to have this right now, but since it has global ones, this ought to be simple to add. (If it isn't again the SVG spec, it can be in the Inkscape-specific namespace.) Then, if the layers palette and "duplicate window" features could be extended to make it easy to compare layers (and thus glyphs) - stacking them, seeing them side by side, and so on. The FontForge tutorial at http://fontforge.sourceforge.net/editexample5.html explains a little about designing metrics - (C). Having the left and right bearings appear as the page size (width) would be simple - and then Inkscape would be extended to allow changing the page size's width directly on the canvas, instead of via the document properties dialog, so just like moving a guideline. But perhaps having layers with different page sizes is against the SVG spec… Although that would be the most straightforward way of setting the sidebearings from a UI perspective, if that isn't possible, having the metrics appear as layer-specific guides with "left bearing" and "right bearing" IDs or Class could do the same job easily enough. But what is really needed is to create a special "metrics" dialog. This could re-use the "duplicate window" feature to grab the glyph's outline and render it on another canvas, a special one where the left and right bearings can be adjusted in the context of several letters next to each other in a word. (Again, see the FontForge tutorial if you're not familiar with font editor programs.) For typesetting text with the font, it would be straightforward to write some (python) glue scripts that open the SVG Font within FontForge, compile it into a system font format (Type 1, OpenType CFF) and then generate a PDF 'specimen' sheet to be printed. But eventually Inkscape will have to be able to render SVG Fonts directly on the canvas, and then it will be simple to have a "paragraph view" layer with some text that uses the glyphs from the self SVG. -- Regards, Dave I support www.gnuherds.org - democratic free software jobs

FireFox (FF2 and FF3)
by Jan Homan 11 Jun '08

11 Jun '08

Regarding SVG support in FireFox, after some testing we came to the following conclusions. (1) tspan is used to position each character (more) precisely on a page (for example if a text string uses kerning) As far as we can tell is that FireFox (FF2 and FF3) does not support this feature. It just ignores the tspan commands. (2) FF2 does not support multiple spaces in string. It looks like FF2 ignores the additional spaces between the words.

Can't get the SWF output working anymore
by Juho Viitasalo 11 Jun '08

11 Jun '08

Can anybody explain why I can't get the SWF output extension working or even it to show in saving dialog. You can find a link to this extension from: http://wiki.inkscape.org/wiki/index.php/ExtensionsRepository I extracted the .inx file to extensions folder, but I can't see SWF file saving option when saving a file. I compared the syntax of the swf_output.inx file to pdf_output.inx.txt file that I found from the same folder. I noticed that <name>, <filetypename> and <filetypetooltip> tags had an underscore in the pdf_output file. I tried to add underscores to swf_output with no success. I also removed txt extension from pdf_output.inx file. After that corresponding saving option appeared to Inkscape. I also started to change pdf_output file to correspond to swf_output file. I could change name and id tags to <_name>SWF Output</_name> <id>org.inkscape.output.swf</id> in pdf_output.inx and it still shows up in save dialog. If I change anything else "Adobe PDF via postscript (*.pdf)" saving option won't show up.

Any ideas? Actually, I would like if one could choose the unit and step of All options out there. For example, when doing Live Path effects, clicking on the "width" field gives me increments of 0.01. Now really, the minimum increment -I-'d want is 0.1. Clicking 10 times just to get 0.1 is not very feasible, so it'd be nice if for all tools, in the options area, you can set a unit yourself. That and, Shift-click to change in increments of 10 times the base unites. Alt-click can go in increments of 0.1 times the base unit too. Does such a proposal exist already?

Proposal: stick to node or stick to segment
by Valerie 11 Jun '08

11 Jun '08

The concept is pretty simple: you take two nodes, you have them "stick" together (think snapping), and when you move the other node directly or indirectly (moving the whole object), the other node stuck to it moves along. Same with segments. It basically makes a copy of that segment and its handles, and sticks all of them together. Same with whole objects actually, I forgot that one, you "snap" the whole object onto a point. Background: I mainly came up with the concept because I like (trying to) do drawings with complex strokes. The new LPE interface makes the complex strokes a lot easier, but if you actually want to fill anything in between, you have to edit the strokes And the fill (basically doubling the edit time). Now, you Could tell me to just deal with it and/or delete the fill and make a new one, but it becomes a whole other story if Inkscape wants to include animation one day, so consider this a preliminary feature: http://img373.imageshack.us/img373/2604/stickynodesja9.png The problem is the interface. We could have a sub-mode of Edit, or a whole new tool, and of course we'll need shortcuts. Then for that new fill option, a new option would have to be added as well. I'm still pondering the matter (as well as the text tool interface), but maybe some of you have ideas already? This way at least we could discuss the blueprint. Maybe when Summer of Code 2009 comes around, some student would be interested and take up the whole thing! :)

SPCurve::get_pathvector instead of get_bpath
by unknown＠example.com 10 Jun '08

10 Jun '08

Hi all, Maybe you've noticed: I reworked the internals of SPCurve such that now it is possible to get the old Inkscape pathtype (NArtBpath) or the 2geom type PathVector (both representations are kept in-sync with each other). I have started converting all calls for the old type (get_bpath or SP_CURVE_BPATH) to the new PathVector type (get_pathvector). Helping me with this conversion would be really nice, but I think I have already dealt with most of the easy ones. Therefore... My request is for *new* code to use get_pathvector! I'm sure you'll find the 2geom type much nicer to work with than the old path type. If you need help, talk to us in the lib2geom jabber channel; some times functionality is lacking from 2geom and we are very interested in hearing about them! :-) Johan

Segfault in select-context.cpp
by Bob Jamison 09 Jun '08

09 Jun '08

Hi, all. I am geting a segfault at line 413 in select-context.cpp during startup: switch (event->type) { where "event" is null. This is in sp_select_context_root_handler(), which is called by, in the stack, sp_event_context_root_handler() sp_desktop_root_handler(), which is called by sp_marshal_BOOLEAN__POINTER() which is a Glib thing. "event" appears to be null all the way up. Has there been a change to any of the knot code to cause this, or am I seeing a typical verb alignment problem from verbs.h being edited and a clean build being required? I did a clean build twice, just in case, but no effect. bob

Merge my branch into trunk
by unknown＠example.com 06 Jun '08

06 Jun '08

Hi Peter, devels, I have just merged my branch back into trunk. Most of SPCurve's methods are also correct for the 2geom path in it, so one could start using get_pathv instead of get_bpath to get path data. If you want to do testing for me, please comment out this line in /src/display/curve.cpp: #define NO_CHECKS (put comment // in front) This enables the checking I have coded at the end of those functions to check whether there is a difference between the NArtBpath repr and PathVector repr. Because of this "doubling" of path operations, things will be slower, but I didn't notice a huge set back. The doubling will be removed when it works 100% okay, so no worries! Thanks! Johan

Minor inconsistency with disabling snapping by "key accelerators"
by Rock Star 05 Jun '08

05 Jun '08

Since I'm using Inkscape mostly for technical drawings I've come across minor inconsistency with disabling snapping by key accelerators. This is an extremely useful feature when you need to temporarily disable, otherwise turned on, snapping - for example for positioning text etc. However, I find the behavior a bit inconsistent. Currently it is like this: If you want to disable snapping by key accelerator while: 1) MOVING a path, shape, group, text etc., you have to press SHIFT. 2) MOVING a NODE of a CURVED PATH, you have to press SHIFT or ALT. 3) MOVING a NODE of a STRAIGHT PATH, you have to press ALT. If you press SHIFT, a straight path becomes curved. So, the 3rd behavior is somehow nonintuitive to me. I think it would be better if the same key accelerator would be used in all cases. I would vote for SHIFT since I'm used of it. In this case I guess that for straight paths SHIFT and ALT should be switched. Though, on the other hand, if ALT comes from "alternative" it would make more sense to use ALT for disabling snapping. Anyway, maybe I'm missing something here, because I'm really much more technically than artistically oriented. So, is there some other explanation of this? Rok

Tablet support on win32
by Bob Jamison 05 Jun '08

05 Jun '08

I have been hearing that there has been some trouble getting Wacom tablets working on win32. Gtk had a bigfix release today, 2.12.10, that mentions Wacom support as one of its fixes. Give this a look: http://inkscape.modevia.com/win32/Inkscape0806041806.7z I added the new Gtk, Glib, and Pango revisions to the devlibs. Just "svn up" now to receive them. If you notice that the build is a bit larger, it's because for some strange reason, Gtk changed the name of their PNG DLL dependency from libpng13.dll to libpng12-0.dll. Rather than spend several days recompiling everything that needs PNG, we'll just make a copy for now. (ARRRGH!) bob

Fwd: Programming for Inkscape.

05 Jun '08

...forwarding this to the devel list... ---------- Forwarded message ---------- From: Pam B. <pamely@...329...> Date: Thu, Feb 14, 2008 at 2:26 PM Subject: Programming for Inkscape. To: buliabyak@...400... Hi, I have been told to contact you by Bibi Morris. I understand that in the past some wonderful people have made changes in Inkscape that made it an incredibly useful program for owners of Wishblade and CraftRobo personal media cutters. I have now been provided a tip that would allow users of Linux to drive their machines directly from Inkscape. The "tip" suggested that Windows users might be able to do the same if someone was able to do something with the windows binary for Inkscape. As is probably already obvious, I know nothing about Operating Systems, nor do I know anything about coding and software programming. Actually, I no longer even own a Wishblade, (I have moved on to a bigger machine.) but I do run a support group for over 1,000 personal cutter owners. This has the potential of being a very powerful tool to owners of these types of cutters and could save them hundreds of dollars in software upgrades. Would you please check into this and see if it is something that can be done for us? Thank you, Pam Beard and the 1,000+ in the yahoo group: EasyWishbladers The "tip" is pasted below: If the words Linux, RedHat, Debian, Inkscape and / or Python mean anything to you read on (warning, getting technical here...). How would you like to cut from inkscape? all in Linux? I have been lurking in Linux Printer Driver land and was very happy to find an early copy of a Python script designed to provide the necessary "linkage" between Inkscape and a craftrobo cutter. With a little change to the code, we verified it works with a wishblade as well. But you might have to wait until there is support in the down loadable python script. Basically, you print from Inkscape "using PostScript operators" (not as a bitmap). And, instead of sending the output to a printer, you "pipe" it to the python application. This operation is actually described in the Inkscape print popup menu. When you click on print, the python GUI pops up giving you more options. This GUI interface is *much* simpler than the actual graphtec software. Most anything to do with the image needs to be done in Inkscape. The only real control on the GUI are the paper size, the cutting speed and the cutting pressure. I suppose this can also be done in windows. My *assumptions* are that there is a windows binary for inkscape as well as python and python related software. If that's the case, then you may be able to skip setting up a Linux box. I know I am hitting only about 1% of you, but if you want to try the script you can get it here: http://vidar.gimp.org/graphtecprint/ ....I am sure feed back at this stage of development would influence what features are fixed, enhanced and / or added. -- bulia byak Inkscape.

Some issues with using .46
by MilesTogoe 04 Jun '08

04 Jun '08

As we're using .46, here are some issues that have arisen (some pre-date .46). Should they be added as RFE's? Sodipodi absolute paths - if you add an image, then delete it, the old image absolute path seem to remain in the file. Maybe it's the sodipodi namespace stuff. In fact is there a good reason for both an xlink and sodipodi:absref for the same image - seems like unnecessary duplication and chance for bugs. Effects|Modify Path|Color Markers - In .46 it's giving a weird warning message box (maybe it is being fixed) and does strange things like accessing the sodipodi full paths (see above). This effect has always seemed to be a kludge since stroke color should be applied when end markers are chosen in the object|fill & stroke|stroke style dialog Effects|Render|Grid - This is confusing. the right grid and guides are in document properties. I used the effects grid by mistake, then couldn't adjust it - had to undo. If the Render grid is for fill shouldn't it be under the object|fill & stroke |fill pattern Open Icon - the blue folder color is very similar to the old save icons (with blue floppy disk) thus, I keep clicking the wrong icon for save - the open folder color should be tan (manila). Object|Fill & Stroke|Fill gradient pattern - trying to use the awesome gradient tools more and I find there is an inside out gradient but not an outside in gradient and I can't figure out how to switch it. This also applies to left-right vs right-left (including the gradient adjustment tool) - this can be worked around by flipping the object but that's kind of kludgy. Finally here's a perfect patch opportunity for a newcomer wanting to get involved: Object|Transform|Scale - switch default scale proportionally to checked - this is a simple gtk checkbox setting

Is the behaviour continuous or discrete (as in, can you set in just about any value or are you limited to a few specific ones?) Same for italics: you decide the slant of the text right? Can you specify just about any value? I remember a person who proposed this handy pop-up slider where you can click and drag left and right pretty easily. If the above behaviour allows you to take just about any value, then I Could see a "bold" drop-down horizontal slider where as you slide around the font becomes bolder. If there are a finite number of values possible, then you could constrain the values of the slider. Same with italics. How does Inkscape actually handle all that though? By distorting the fonts to hell? (something I don't really have a problem with, as long as it doesn't cause the memory usage to go to hell because handling of long text always seems to eat up my memory like no tomorrow right now?) Speaking of that person's handy slider thing, I don't suppose anybody is going to implement it anytime soon? (a pity, because it's real handy. One-click value adjustment. Somebody should really make that widget)

UI proposal for text in shapes
by Valerie 04 Jun '08

04 Jun '08

Well, work on the vector brush interface is just about done, so I've tackled another thing I'd like to have (though it's not as significant): proper flowing of text into shapes (chart items in particular). At first I thought about making dedicated chart shapes, which have an automatic text box at the centre (or defined alignment position). Then I thought about adding the functionality to existing shapes. Though it still doesn't address the question of non-predefined shapes. So, the simplest way in the end is to add the functionality to the text toolbar, so that it can be applied to any shape. http://img294.imageshack.us/img294/1162/textinterfacelk4.png Note the grid by the way. Whoever thought of it first (not me, but I don't remember who. It was proposed for some other Inkscape feature though) is genius. You can align the text to: - top-left - top-center - top-right - middle-left - (you get the idea) Why this proposal? - because the align grid eliminates the need for calling up the bulky align dialogue all the time when doing chart items. The current flow functionality always starts at the top-left corner, unless I'm missing something. - because the padding means you can use the actual shape as border, instead of having to manually make a smaller version and stuffing the text into it. I suppose this would address the following wishlist items: https://bugs.launchpad.net/inkscape/+bug/171105 https://bugs.launchpad.net/inkscape/+bug/171602

I have been working on an > Inkscape plugin for testing it, so maybe that would be a better way to > introduce this type design interface into Inkscape - then we can talk ;) I can't help with that unfortunately, I have no idea what you'd be trying to achieve UI-wise. On the bright side, I've thought up a possible interface for the toolbar. However, I'd suggest the option to revert to "simple" mode for those who aren't used to it. The fontface choices would basically be done in a drop-down: http://img147.imageshack.us/img147/7818/textstylesmk2.png (rough drawing for now, I'll do the nicer looking version later) Mouse-over the values will also reveal their names (bold, ultra-bold, heavy etc) Now it would still be cumbersome no matter what you do because there are just that many options. However, Mouse-over to Each field Must reveal the shortcuts, which would get the users to quickly get used to them and thus minimize their usage of the drop-down. Shortcuts: - Ctrl+I: toggle between italic modes (normal, oblique, italic) - Ctrl+B: make bolder. - Ctrl+Shift-B and Ctrl+L: make lighter. - Ctrl+E: expand. - Ctrl+Shift+E: contract If gravity is added in there, then sure. As for "weight," it'd go like this: if for a style (say, Italic), there is no font for that weight, they the implicit weight value stays the same, but Italic takes on the next closest value. The explanation to the user is that "Italic with Bold" and Italic with Ultrabold" look the same. And that's about it. A possible alternate interface is that Italic gets drop-down value boxes and Bold next to it gets a drop-down horizontal slider. The other options still get stuffed into a drop-down.

Knotholder C++ification
by Maximilian Albert 04 Jun '08

04 Jun '08

Hi all, in rev. 18775 I committed some changes to C++ify the knotholder-related classes (this was made necessary by my LPE-integration work). Basically, I just rewrapped the existing functions as methods of the new classes KnotHolder, KnotHolderEntity etc. Although the changes were quite straightforward, there is a chance that some code got lost in the process, so please watch out for any regressions!! The main change to be aware of when writing new knotholder code is perhaps that each knotholder entity (which among other things encapsulates a visual on-canvas handle) should now derive from the "general" KnotHolderEntity class and override the virtual functions knot_(get|set|click) which are responsible for the actions taken when the associated handle's position is read/set or when the handle is clicked. Similarly, each item-specific knotholder class (like RectKnotHolder) now derives from the general KnotHolder class, and in its constructor the necessary KnotHolderEntities for all required handles are created. Note that a KnotHolderEntity must currently be explicitly created using the create() method (i.e., this does not happen in the constructor).[1] I'd welcome any comments because although it works well, it still seems slightly awkward to have a new class for each knotholder entity and each knotholder. Did I miss anything and is there a more elegant way to organize things or is this indeed the way to go? More on my other and yet-to-be-committed work in a separate email. Cheers, Max P.S.: Known issue: LPE PointParams are currently broken and they cannot be edited on-canvas. I hope to get this fixed very soon and then the cumbersome edit-on-vanas button will disappear, too. :) [1] I know that there used to be a good reason for this but it may be the case that due to some later refactoring it's not necessary any more to have it this way. In any case, I left it for now because it slightly declutters the declarations of the derived classes. Please tell me if you want it changed.

SVG Filters optimizations
by Felipe Sanches 04 Jun '08

04 Jun '08

I have seen an article (in the Beautiful Code book that Google sent me as a SoC gift) about runtime code specialization/compilation using C# in order to optimize code. I was thinking about using similar things to optimize our SVG Filters code but I don't know whether this kind of thing is possible in C++. C# can run bytecode generated in runtime. How could that be achieved in C++? I also have seen an article about a library for C++ that seems to do exactly this, but the lib is non-free: TaskGraph (http://www.doc.ic.ac.uk/~phjk/Software/TGL/) Is there a free-software lib for this?

NEW : LPE stacking
by Steren Giannini 04 Jun '08

04 Jun '08

Hello, Our student project is now finished. Thanks to our mentor Johan, our work is now in main trunk. For us it is a real pleasure to see that. Our goals were : - LPE stacking : Check it out - LPE for groups : has already been committed - LPE envelope : we created 2 deformation effects, the first one is "Envelope", the second is "Lattice" and is based on the d2sb2d object from 2geom. They are not designed for the same use. Indeed, while the lattice offers an accurate deformation, this deformation is only determined by control points. It also allows the user to move inner control points, which can't be done with the Envelope deformation. The power of the Envelope deformation is the absolute control of the shape of the envelope. We made lots of efforts to correct bugs we found, but you may find some more. Concerning the school, our teachers told us our project is one of the best of this year. They qualified it of "excellent project" and they were very glad to see our results. I hope this will spur the students on to work on open source project. I intend to continue working on Inkscape, first by "polishing the edge" of our actual work and then by adding things I have in mind. I hope people will like and use what we did. Thanks again Johan and the inkscape community, The team : De-Cooman Aurélie Tebby Hugh Falzon Noé Bouclet Bastien Navez Victor Giannini Steren

And at latest Libre Graphics Meeting in May > it was discussed with Behdad from Pango team. Alright, alright, I think I get it more. It's fine for keyboard, I suggest just going with Ctrl (or Alt) and the directional keys in text mode. They don't seem to be taken in text mode. Simple right? For the top level interface though, there's the problem of what takes precedence. The drop-down can still be used, but the available values of one would depend on the available values for the other, as you've given with the example of Italics. And I Really doubt people would want to see a check box system. Ah great, I just took a look at the Pango manual. There's a whole series of bold values in there And stretch (and a few other things. What, pray tell, is "font mask gravity"? Well, fortunately, there are only 3 values of Italics: normal, oblique and italic, so that can be the starter value: once you've chosen one of those, the available bold and stretch values pop out, all of which could still be set to a slider interface. A button somewhere could show a matrix of what's available in each mode (...). Have you set a date for when you'll be discussing with the Pango people? It'd be a Lot easier to think up an interface if I actually knew what needs to be implemented. As I've said, keyboard-wise, just go with modifier key + directional arrows. Up-down for bold, right-left for stretch (hey, that's pretty intuitive!). For the rest though... > With such modular typeface engine, we could have fonts where you > can modify stuff like how bold you want your font - though > obviously only on fonts generated with the same engine. Nice concept, except people will probably be expecting a lot more than the modifiable fonts. On well. :( Anyway, I have to log off for today. One of these days I may try to look into Pango more, but that'd take some time since I really don't know much about fonts. Unless someone else knows how to deal with the issue instead? :)

Re: [Inkscape-devel] UI proposal for text in shapes
by Valerie 03 Jun '08

03 Jun '08

Alright, here's what I've got for now (below is the draft of what I'd put in the wiki): Text-UI-improvements Text UI with space, kerning, path and flow Summary: An improvement of the text toolbar functionalities, adding: spacing, kerning, put-on-path, flow-into-shape (with auto align and padding values) and perhaps more font styles (underline, etc.). All this is done without making the toolbar excessively long via usage of drop-downs. http://img135.imageshack.us/img135/5168/textinterface1ix1.png The interface: - (by the way, can the font size value drop-down be made slightly smaller?) - clicking on "Spacing" pops up a temporary drop-down, where you can set the line spacing and letter spacing values. Clicking anywhere else closes it. It is assumed that users would not need to modify these Too often. - the "horizontal layout" button is eliminated to save some space. - more font styles are accessible from the toolbar. However, this may take too much space, so see below for alternate toolbar. - Kerning is also accessed via a drop-down. There you can set values manually, but mouse-over will reveal the shortcuts, so users quickly learn how to manually do kerning instead of having to use the drop-down all the time. A button enables the user to remove all kerning. - the "put text on path" operation is included onto the text toolbar. To use it, you simple select both the text and the path, and click the button. Clicking again removes the operation. - the "flow text into shape" is very useful for charts and comics. However, the current operation is too limited because of the absence of padding and alignment options. More precisions below. Note that I have made heavy use of down-downs. There are two major differences between such drop-downs and popping up a whole Text dialog that makes them hopefully more pleasant to use: - they're Smaller. i.e., less cumbersome. You can access exactly the operations you need without popping up something huge in the middle of the screen. - they disappear as soon as you click elsewhere, so you quickly get them out of the way. - and yet they still allow you to quickly access some operations that are hopefully not Too frequent. Precisions on the "flow into shape" section: - I often make charts, and it is extremely cumbersome to bring up the align dialog all the time just because I want to align a text to the center of a shape. Ideally, this should be automatic. I forgot who first came up with the align grid for Inkscape, but credits goes to him! :) The align grid is as its name implies: clicking on the center aligns the text to the middle-center of the object (as is often the case for chart items and comic bubbles), the top-left option is most use for text boxes. Right- alignment would be handy for Asian layouts. See examples: http://img176.imageshack.us/img176/7099/alignmentbc9.png - Also, the padding is automatic: it basically automatically creates a shape inset of that value, and flows the text into the invisible shape. This way the form can finally be used as the actual border of the frame instead of other complicated work-arounds. - Ideally, the x and y values of padding could be set independently, but it is otherwise not really a problem because in the case of comic shapes, for example, the text would be aligned to middle-center so the top and bottom borders will rarely be reached. Alternate interface: the following interface presents ideas to further reduce toolbar length: http://img260.imageshack.us/img260/8550/textinterface2nb3.png - the text align options would be reduced to a single button with a horizontal drop-down. However, users would probably like to have these options at top-level. - instead of cluttering the bar with font styles, another drop- down could be used. What goes into this drop-down depends on who plans to stuff it: it can be more buttons, check boxes, even complex drop-downs like Open Office (though hopefully not That complex and not That big). This allows users to access a wide range of rare styles as they are made available. - if the x and y padding values of "border" for text flow can be modified separately, then they get grouped into a drop-down as well. Anyway, I know many of you are busy. I'll probably leave this proposal up for about a week, and in the meantime, I'm open to any additional suggestions, or I'll wait longer if anybody gives a more specific date on when they'll have time. As you can see, many of the elements have several possibilities, so there could be additional refinement there as well. :)

This, however: https://bugs.launchpad.net/inkscape/+bug/188849 Gives me errors (mostly ¡®sp_curve_unref¡¯ was not declared in this scope and similar) Unfortunately I have no experience no the matter.

Once again, congratulations on the terrific work done with LPE stacking! I'm having a blast putting all sorts of shapes on Spiro lines (which convinces me more than ever that we should have Spiro lines as a sub-mode of Pencil and Bezier: it'd basically be an automatic Spiro line upon a bezier, minus the annoying bezier skeleton popping up all the time, yes? ;) ) Now that was a blast! http://img118.imageshack.us/img118/2219/lpesqm7.png I tried deforming a text with Envelop by the way but found a bug instead: the LPE dialogue didn't let me do effects with Text so I tried to convert it to path first. Result: Inkscape seems to crash if you select the text then the edit tool (F2). The console says: (inkscape:7044): GLib-GObject-WARNING **: invalid cast from `SPText' to `SPLPEItem' Does the same problem occur to anybody else? I suppose I should file a bug. There is no such bug on 0.46 though, and an exported text can be deformed just fine.

Hi all, to "officially" kick off my GSoC project I have made my initial draft available as a LP Blueprint: https://blueprints.launchpad.net/inkscape/+spec/tech-drawing I'd be glad if folks added their suggestions and ideas there (and/or reorganize stuff if it seems helpful) so that I can get an impression of which features are most wanted and how people imagine them to work most smoothly UI-wise. As for coding, during the last 1-2 weeks I did some experiments with LPEs in various directions. Some of these are in SVN already, but overall it was mainly to get an impression of what is already there and what still needs to be done in order to integrate LPEs more tightly into existing tools. In the next few days I'm going to write an email summarizing my thoughts and giving an overview of the first steps I'm planning to take. Max P.S.: As I'm still not subscribed to inscape-user, feel free to forward my email there.

Re: [Inkscape-devel] Resource paths on win32
by Bob Jamison 31 May '08

Ok, This path stuff on win32 has been biting us for a long time now. :-) So I added some code to prefix.cpp to provide a macro, WIN32_DATADIR, that works similarly to BR_DATADIR, so that paths are calculated now, rather than static. So INKSCAPE_EXTENSIONDIR, for example, will always be valid, no matter what the CurrentDirectory is. In fact, we should make sure that CurrentDirectory does not affect resource loading at all. It seems to work OK. If anyone sees an Inkscape win32 build that looks like icons/menus/etc might be missing, please let me know. But I really consider this a short-term fix. If we actually jumped into the deep water, quit using strings for paths and started using URIs, then this problem might disappear forever. bob -----Original Message----- >From: Albin Sunnanbo <albin@...1900...> >Sent: May 29, 2008 12:35 PM >To: Bob Jamison <rwjj@...127...> >Subject: Re: [Inkscape-devel] Resource paths on win32 > >Hi >I did some bugfixing with extensions a while a go.

Re quest: Calligraphy Tool - Union and difference button toggle
by microUgly 30 May '08

30 May '08

I actually posted this idea on the forum last year (http://www.inkscapeforum.com/viewtopic.php?f=28&t=304&p=1693) and then being without a PC with Inkscape for almost 7 months meant I never got around to posting here for developers opinions. I believe that most artists, when inking a drawing, will ink a line with many strokes to accurately control the shape of the lines. The problem at the moment is that multiple strokes create multiple shapes. You can hold SHIFT so they only form one shape, but this is awkward when you're using it most of the time. So I would like to see a toggle on the Tool Control Bar that allows for union without holding SHIFT. Likewise I would also like to see a toggle that has the opposite effect and performs a difference. This toggle obviously conflicts with the new Eraser tool so I'll let you guys debate which is more intuitive or less cumbersome (I assume the erase tool will share the exact same tool controls as the calligraphy tool) This is a simple screenshot of what I'm talking about - http://www.microugly.com/images/calligraphy-union-difference.png -- View this message in context: http://www.nabble.com/Request%3A-Calligraphy-Tool---Union-and-difference-bu… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

UI proposal for Freehand with automatic LPE (stroke effects)
by Valerie 30 May '08

30 May '08

Hey Bulia! Happy now? :) http://img67.imageshack.us/img67/5248/lpeiz6.png You'll notice that I've submitted several proposals in one. I included them in one mock-up because I needed to make sure everything fits (they seem to, the current version is just about the same size as the toolbar for the selection and calligraphy tools). The 4 components (which ones to be included to be seen are): 1. The Width x base unit component. If you set your base unit to 0.2 pixels for example, you can increment the width of the stroke in increments of 0.2 pixels with just the directional keys. :D 2. I'd like to see Mode there too, because I rather like the smoothness of the freehand tool in Karbon14. Instead of Karbon14's "exactness" and "combine angle" text though, I just called it "smooth", because it's pretty intuitive, not to mention short. :\ I'm not sure if it will get added, but I'd be pretty happy if it were. For those who've missed it, the output of Karbon14: http://img137.imageshack.us/img137/9927/karbon14px5.png (for me, Inkscape's current output is closer to Curve with exactness of 5, not more) 3. The drop-down allows you to chose the behaviour of the line! Either a normal, simple line, LPE with presets, or LPE with clipboard items. Lots of fun, no? You can create a shape and make a true vector brush out of it! (example: you do a leaf shape, you copy it, and you start "drawing" it in various sizes everywhere on the file. Whoo-hoo! How pointless! Moving on) Anyway, the presets drop-down allows you to access dotted lines for normal lines and pre-defined shapes for LPE lines (I'm naming them calligraphy just because. If you name them Live Path Effect or Pattern Along Path, most users will probably not get it...) 4. Finally, I wouldn't have markers accessible from the top-level. Again, this depends on whether people agree or not, but I find it handy when doing charts. Very. Actually, I've just noticed that I forgot the "pattern copies" components of LPE. Aww geez. Maybe for Clipboard, there could be sub-modes that take up the place the Markers buttons would. Icons: - single instance of a small shape - single instance of a shape stretched - multiple instance of the shape along the path - multiple stretched instances of the shape along the path Not as necessary for those pre-defined calligraphy shapes though.

Yes. For example, a drop-down with a list of LPEs with some preset parameters and a "last used LPE" entry, and separately from that a drop-down with profiles as in your mockup, implemented as pattern-on-path LPE (and therefore disabling the LPE chooser, until we can support more than one LPE per path). > That's workable.

This is a relatively minor point - but Calligraphic pen works fine using the current fill color for its "strokes" and nobody complained so far :) -- bulia byak Inkscape.

Toolbox management proposal (presets and tool toggle)
by Valerie 30 May '08

30 May '08

Before I start... what can I submit as "blueprint", and what should I be submitting as "wishlist" instead? Can I use the wiki? If so, what pages am I supposed to save them as? Anyway, most of these will be submitted separately, but they're all only made feasible with a proper toolbox management. So the toolbox is getting cramped, right? At the same time, it's not really fun when many tools are grouped and you have to find each sub-component (case of the tweak tools, I can never remember the shortcuts either). So here's a possible solution, and some possibilities that'd derive from it. 1. Toolbox proposal http://img113.imageshack.us/img113/416/toolbarmanagement1ov3.png http://img146.imageshack.us/img146/3712/toolbarmanagement2xb0.png Some features: - There should be a visible icon, as people won't be able to find the feature otherwise. - The icon allows you to access toolbox presets. - Managing a preset is easy, just go to "configure toolbox" and toggle on and off the visibility of any tool, just like with Gimp. - Multiple toolbars may be possible: see mock-up 1. The additional floating toolboxes would have a close button, though not the "main" one to avoid confusion (insert "Aaah! My toolbox has disappeared!" messages). - Some tools could have "grouped" and "separate" options (mock-up 2). Examples: . square, ellipse, spiral and polygon can be options of a single "shapes" button for those who don't use them often. . the individual modes of the tweak tool could be accessible separately: see mock-up. . when 3D shapes are added, they'd also have both grouped and separate options. - Since management is easy now, have some LPEs as tools too? Please? PLEASE??? 2. LPE as tools With a proper toolbox management system like the one above, LPEs can be incorporated as tools when needed. It saves one the trouble of applying one from a panel every time (it Really breaks the flow when you have a lot of lines to do, not to mention the LPE panel takes up a lot of space). This would simplify interface for many LPEs tremendously. You just select the tool, modify any necessary parameters, and draw the paths you need. As soon as you've drawn the path the effect is automatically applied. For example, Spiro lines: you draw your normal bezier, and as soon as you release the mouse it becomes a Spiro line (by the way, any chance for "native" Spiro lines as opposed to a Bezier with an LPE on it?). I actually think LPEs should eventually be separated into categories: - Spiro lines (native spiro lines? Yes please!) - Complex lines (sketch, waves, wide) - Shape generators (gears, stiches, etc.) - Guides (grids, technical, composition guides, perspective guides) - Transform (envelop deform, perspective deform) - etc. 3. LPE tool: Wide lines It's crazy, but it's nearly impossible to find a program that would let you do a nice double-edged line without either: - a tablet (+ very steady hands, which I don't have) - half a dozen operations - or forcing you to switch between panels. It's Really discouraging when you want to do several hundred hair strands. D: The wide lines LPE would be a very simple tool: a few basic shapes are saved. You draw your path. The shape automatically gets stretched onto it: http://img164.imageshack.us/img164/9302/widestrokeslpemx3.png There you go, easy-to-edit (direction wise, in any case, I'm assuming that a person doing dozens of hair strands does not care about the exact form of each) double-edged stroke drawn in a single operation with a mouse (or with bezier, whichever). Note: Developers will probably not want to set this as a tool until a proper toolbox management system is in place, which is why I proposed one myself (though I'd be more than happy if a better solution comes along). For this particular LPE tool, you'd have the following entries: - size: size of the maximum. It basically takes the saved shape and adjusts the size first, so you can modify the width of the strokes with just the directional keys. - presets: preset shapes: single edge, double edge with max at 1/2, double-edge with max at 1/4, etc. Users can add their own commonly-used shapes, but the above are among the most ridiculously common ones. - and you can adjust the size with just the directional keys! (though there could be %width options to further tweak the thin lines) If anybody knows how to automatically generate shapes likes these, that's fine too (though let's be honest, including a few files of shapes like these would take up tiny disk space anyway. They're 4 nodes each!). 4. Tool for charts: shapes with text Another feature that probably would be considered too much waste of real-estate without a proper toolbox management. I often use Inkscape to do charts. Having to call up the Align dialog each time (which really takes up a Lot of space by the way) just to place a few text into shapes, and having to realign every time the text is modified, is needlessly tedious to say the least. The auto-text shapes I'm proposing would come as Ellipse, Text, or Polygon. They're simple: place a shape, click on the center and you can start typing away. The text is always automatically aligned to center (or some other option of your choosing). They may have the following features or options: - padding of text to borders: sets a minimum distance between the text and the border. - auto-adjust size: if the text starts to fill the shape, the shape resizes automatically to fit. - the default is for the text to be centered, but there could be other alignments. - linked duplicates: a linked duplicate only conserves the shape, not the text content, so by making a duplicate, when the text in one of the boxes forces one of the items to become bigger, all the other shapes of the same type resize as well. This is for those charts that need all elements to be of approximately the same size. - adding points for connectors: this is simpler for rectangle shapes than for other shapes... you can basically specify how many connector points you want per side (example: 3). Though, ideally, there'd be an on-canvas means to mark points for each side, but I don't have UI ideas for that one... Also handy for comics. It's at least three steps fewer (changing the tool, selecting all then aligning the whole, not to mention it has to be repeated if the text is changed much) for a rather common task, which can translate into a good enough time gain and a much more pleasant work flow. Any comments before I submit? (if only to say which ones should Not be submitted as blueprints, because I'm a bit confused right now)

Resource paths on win32
by Bob Jamison 29 May '08

29 May '08

Hi, wormsxulla alerted me to a problem with the Tutorial menu items not being able to load a tutorial file. The error is something like "can't load file \share\tutorials\blah.svg". Which makes me think that Inkscape has forgotten its path some time since startup. It must have known -during- startup, else you wouldn't get your icons or translations. Has anyone done anything recently to change the path-prefixes, or CurrentDirectory of Inkscape? This was working before. bob

Proposed change of config directory
by Jon A. Cruz 28 May '08

28 May '08

In discussion today the subject of our preferences, etc came up. The initial comment was "also, i really would love to be able to store the inkscape preferences files in a given location (so, to be able to run two builds alternatively without having to save & rename the prefs files manually). profiles!" Looking into that, it seems that perhaps we should switch some of the mess that is path-prefix.h with the stock calls that now are in glib and that follow the XDG Base Directory Specification http://www.freedesktop.org/Standards/basedir-spec In fact, we should perhaps look over a few of those "Miscellaneous Utility Functions" in glib http://library.gnome.org/devel/glib/stable/glib-Miscellaneous-Utility-Funct… The immediately useful function would be g_get_user_config_dir(). One main benefit of using that call is that Inkscape should then be easy to direct to different "config" directories and allow for users to pair different versions of Inkscape with different directories... or different work scenarios with different ones, etc.

[Lib2geom-devel] New HLineSegment/VLineSegment classes and path.h splitting
by Marco 28 May '08

28 May '08

I splitted path.h in the following files: curve.h (abstract class Curve) sbasis-curve.h bezier-curve.h elliptical-arc.h path.h (class Path and iterators ) and path.cpp in curve-helpers.cpp (CurveHelpers::root_winding) path.cpp (all the previous methods) finally I added a curves.h file so defined: #include curve.h #include sbasis-curve.h #include bezier-curve.h #include elliptical-arc.h #include hvlinesegment.h path.h includes curves.h so existent code should have no problem. The HLineSegment and VLineSegment classes will be useful to represent directly "H" and "V" curves found in the svg path element. I committed all changes both to 2geom and Inkscape. Btw I needed to do a make clean before succeeding in building inkscape correctly, because at beginning CurveHelpers::root_winding was seen as defined more than once.

inkscape community site
by Frank Karlitschek 27 May '08

27 May '08

Hi guys, I'm running openDesktop.org, KDE-Look.org, GNOME-Look.org and other websites for Free software. I´m also a longtime inkscape user. I created lots of icons for KDE with inkscape. :-) I noticed that there is no real community site where Inkscape users and developers can share drawing, templates, scripts, fonts, screenshots, new ideas and other stuff. I know there is open clipart, but it lacks the social networking functionality and other stuff. So I created www.inkscapestuff.org . It is part of the openDesktop.org network. So if you have an account on GNOME-Look.org on any other website you can login. There is also a public api if you want to fetch and integrate the stuff into other websites or Inkscape. http://api.inkscapestuff.org I hope this is helpfull for you and the Inkscape users. What do you think? I you have ideas or suggestions how to improve the site please send me a mail. Cheers Frank -- Frank Karlitschek frank@...1981...

UI proposal: workspaces (art, chart, technical, kids)
by Valerie 27 May '08

27 May '08

Inkscape doesn't need this as much as some other graphics programs probably do (I'm mostly trying to push it for Krita), but since Inkscape is going to add technical drawing capabilities, it's as good a time to start considering this as ever: Workspaces would basically be a divide and conquer approach against excessive UI bloat. Basically, 1 workspace = one saved set of settings (including toolbox items and tool option settings). UI: in the top menu, you add a Workspace drop-down with the following possible entries: - General - Icons/logos - Art - Charts - Technical - Kids - anything else you can think of (comics, maps, whatever) Click on any entry to switch from one to another. Art for example will emphasize the Calligraphy tool (with eventually several settings possible and separate entries toolbox entries for the tweak tools, so you don't have to dig them up all the time). I'd also like to see a separate workspace for Composition when composition tools are created (the workspace would basically give you composition tools and a few basic drawing tools). In workspaces such as Charts, tool option settings will automatically switch to properties such as "disable scale stroke width." You could also implement hybrids of the shape and text tools so that when you click on the centre of a shape (say... rectangle), you can start typing and editing text directly, and the text will automatically align itself with the centre of the shape, and/or the shape automatically expands when necessary (options available). Normally, such a feature would add bloat to the UI, but within a specific workspace it'd Really save time since the user would no longer be forced to align all the time. Really, this could cut down chart drawing time by half. Technical drawing will emphasize technical tools while pushing back all the non-technical items. It may also have default grids and snap settings. Within each workspace, you can still add another of the existing tools. This could be done either via a "configure toolbox" button or within a "Configure workspace" entry in the workspace drop-down. There, you just tick the tools you want in your toolbox. Workspaces could also make one's life simpler when the following start to get implemented: - animation (I Really doubt most people want the animation features taking up screen real-estate most of the time) - collaborative online work environments and such? The difficulty, of course, lies in whether Inkscape has the architectural options necessary to save and switch settings in such a way. If possible though, it will decrease UI bloat while allowing easier access to certain tools depending on the task (like the sub-modes of the Tweak tool), and could eventually allow some workspaces to have features that would otherwise be bloat in others (timeline bar for animation, maybe mini-icon galleries for if those are needed, and the shape/text hybrids I've mentioned for a chart workspace).

Suggestion: Calligraphic presets - save and edit
by microUgly 26 May '08

26 May '08

Sorry if I'm raising a suggestion that has already be discussed. I've just tried out the calligraphic preset option in the May 22 Win32 snapshot. When you select a preset and make a change, instead of the preset selection jumping to "No preset" can the preset selection remain except with a "*" beside the name (i.e. Marker*)? This will make it easier to identify which preset you had been using before making a change. When you choose to save the changes, populate the "Profile name" (should that be changed to "preset name"?) with the select preset name so you can easily save over it. With these changes you could change "No preset" to "Default" and allow users to easily define their own default. In my work I'll probably create a few presets combinations such as "Slow thin" and "Fast fat" etc. But every drawing will be slightly different, and in some cases the same part of the same drawing might require tweaking of the settings. So being able to quickly tweak and save my presets would be an useful feature. -- View this message in context: http://www.nabble.com/Suggestion%3A-Calligraphic-presets---save-and-edit-tp… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

SVG Fonts: current status
by Felipe Sanches 26 May '08

26 May '08

------ If you just wanted to see some SVGFonts rendering, stop reading, this is not ready yet... ------ I have been working on SVG Fonts and I have recently created a coupe of files (src/display/nr-svgfonts.{cpp,h}) to deal with cairo userfont feature (rendering). It is still incomplete code, of course. I am sending a patch attached to this email. It has several issues: * Still doesnt render at all :-P (but the cairo userfont callbacks seem to be called properly, so it is a matter of time&pacience to get it working) * The userfont callbacks are called only once for each glyph. It means cairo is caching my glyphs, which will be a problem when the user modifies them. * It deals with only one <font> declaration (should be extended to various svgfonts in a single document). * Currently I have been trying to test this code by calling cairo_set_font_face (ct, nr_svgfonts_get_user_font_face()); cairo_show_text (ct, "A!@A"); But I do not have a proper place to put this call. I have tried to call if from within nr-arena-render-glyphs.cpp, but it is probably wrong. * Our SVG fonts are not registered to the fontlister nor managed by pango yet. * We still depend on pango integration so that we can fed pango with our cairo_font_face_t* created by nr_svgfonts_get_user_font_face(). This would be integrated with the current pango code that exists in inkscape. * I also admit that I need to study a bit more about how inkscape handles units and how these are fed to cairo. Some units&coordinates in this patch are arbirary guesses. Also, this patch depends on linking inkscape to cairo development branch (git master) which has support for userfonts. That's one of the reasons why this has not been commited to svn yet. I don't want to branch, but I will do it if there's no other option. I would rather prefer to have --enable-svgfonts option in ./configure Can anybody help me with that? I have never done this kind of thing. cheers, Juca

Things worked perfectly until maybe a few days ago. I just tested a previous build of may 15th, but that one works just fine. Is anyone else seeing this? Does this ring a bell for someone?

Calligraphy Tool
by Fela Winkelmolen 25 May '08

25 May '08

Hi! I'm currently implementing a calligraphy tool, much like the one present in Inkscape, for Karbon as a Google Summer of Code project. I've heard rumors that there is a plan to rewrite the calligraphy tool of Inkscape, but I couldn't find anything in the ml archives about it. If I understood it correctly the main reason is to make it possible to edit the path in an easier way--actually making it possible to edit the path drawn instead of the final shape created by the tool. I've heard the idea seem to be to use pattern on path, but that doesn't seem to me to be very easy to get right, particularly becase in this case the "pattern" depends on the path. I would like to hear more about this, is there any concrete idea about how it would be implemented, or is it only a vague idea? Also, if you have any other kind of advice, please share! =) Thanks, - fela

memory usage
by Florian Lohoff 25 May '08

25 May '08

Hi, i am thinking of digging a bit into inkscape code concerning the memory usage. As some might know inkscape is used for rendering tiles for OpenStreetmap (Osmarender) or better InformationFreeway. I have seen inkscape regularly consuming up to 12GB (yes - twelve GIGABYTE) of memory to render a tile. Less complex tiles get away with 300-1200MByte of memory which also is a huge amount of memory. This memory issues reduces the number of machines capable of hosting the "tilesat home" client quite drastically (64bit Linux with 16GByte of ram). I have seen that there way a Memory track for the Google SOC 2006 to reduce the inkscapes memory - What has been the outcome to this? My first imagination is that probably the garbage collector does not kick in because of using inkscape in batch mode or somethin. I ran inscape with GC_LEAK set and found the GC running so its not an issue of not reclaimed memory.

<title> and <desc>
by Stephen Silver 25 May '08

25 May '08

I'm currently working on making the title and description fields in the Object Properties dialog work (bug 171024). SPObject already had some dummy member functions to get and set titles and descriptions, so I've turned these into working functions. But I see that there are also dummy non-member functions that are supposed to do the same thing. I could easily implement these using the member functions, but it seems like pointless clutter to have both member functions and non-member functions doing the same thing, so I'm tempted just to delete them (they are not used anywhere, except in the macros SP_OBJECT_DESCRIPTION and SP_OBJECT_TITLE, which are themselves unused). Is there any reason to keep the non-member functions? -- Stephen Silver

Path intersection, union, difference code
by Frederich, Eric P21322 21 May '08

21 May '08

Hey guys, I'm writing a program that generates SVGs. I realized how big of a pain paths are. Right now I am basically just doing straight lines. The curves that I do have are radii and they're all 90 degree semi circles. Those were a pain too, luckily I stumbled upon http://www.whizkidtech.redprince.net/bezier/circle/ and I can create them in my paths. Anyway, I'm at the point where I need to start doing some more complicated things. I can do these things easily in Inkscape but I'm finding it difficult to generate the path data directly. I am wondering where in the source of Inkscape I can find the routines that do the intersection, union, and difference of paths so that I can incorporate it into my code. Thanks, ~Eric

Accessing individual nodes in a path

Hi, for a couple of applications I have in mind it would be very desirable if one was able to access and refer to individual nodes in a path in a way that is unaffected by future insertion/deletion of other nodes (in much the same way as accessing the members of a linked list is unaffected by insertion/deletion of other elements). How easy would it be to achieve this, especially considering the change of path representations to 2geom? What would be necessary to implement it? Can this be easily integrated into existing path representations? Max

NEW: SVG Output preferences
by unknown＠example.com 20 May '08

20 May '08

Hello all, I have exposed the SVG Output preferences in a new tab in the preference dialog. Because of some of the preferences I am not too sure what they do, the tooltip text might be wrong. I hope someone who does know can fix them. The "allowshorthands" option seems not used anywhere in Inkscape code. Does anybody know what happened with this option? (I have commented it out, so it does not show up in Pref dialog) Thanks, Johan

categorisation of LPE
by Alexandre Prokoudine 20 May '08

20 May '08

Hi, There are 15 LPE in the combobox currently and at least Lattice Deformation LPE is going to hit 0.47. Then pluggable LPE are coming. Should we start thinking about catogerisation of LPE before the poor little combobox is overpopulated? ;-) Alexandre

edit image externally
by Felipe Sanches 20 May '08

20 May '08

JonCruz, this is a really nice idea! One little issue: when xlink:href contain a relatve path, gimp does not find the image. Try to edit externaly the image used in share/icons/feConvolveMatrix-icon.svg Its xlink:href attribute is set to "./ticotico.jpg" cheers, Juca PS: I have seen sodipodi:absref="ticotico.jpg" Doesnt absref stand for "absolute reference"? If so, why isnt it storing an absolute path to the jpg file? Also, I guess, absolute paths in xlink:href are evil, since they often only work on the drawing author computer :-P

No default units in dev build Inkscape0805062005.7z
by worms invasion 20 May '08

20 May '08

I have downloaded http://inkscape.modevia.com/win32/Inkscape0805062005.7z yesterday, and tested it. It has a weird problem : no default units are showing, and nothing is showing when I try to use the drop-down menus to select a unit. I am on Windows 2000 - which is known to have problems with drop-down boxes, but nothing can be done at OS level, I believe. Anyway... Has someone the same problem on other OSs? Also, when I enter 10.00 in the box to transform, it becomes 1000000.00, but I can't select "pix". Same in the document properties.

isFinite() problem again
by Maximilian Albert 19 May '08

19 May '08

Hi all, recently there was a discussion about name clashes involving is_finite(). The problem appeared to be solved but now I ran into it (or something similar?) again. Namely, adding the line #include "live_effects/effect.h" to object-edit.cpp yielded the following compile error: object-edit.cpp: In function ‘void sp_spiral_outer_set(SPItem*, const NR::Point&, const NR::Point&, guint)’: object-edit.cpp:1121: error: ‘isFinite’ was not declared in this scope When I additionally changed the line #include "isnan.h" to #include "2geom/isnan.h" and replaced isFinite() with IS_FINITE(), compilation worked fine again. Thus it seems that there is some kind of clashing between isnan.h and 2geom/isnan.h. Has anyone else seen this and what should be done to avoid further difficulties in the future? Max

NEW: Spiro splines LPE
by bulia byak 19 May '08

19 May '08

Spiro splines are a novel way of defining curvilinear paths developed by Raph Levien. Recently, Spiro support was added to the FontForge font editor, and now it is available in Inkscape too. It takes some getting used to, but for certain tasks Spiros have a clear advantage over Bezier curves. http://www.levien.com/spiro/ A Spiro path is defined by a sequence of points, but unlike a regular path with Bezier curves, all Spiro points lie on the path and there are no off-path handles. The curvature of the path is defined entirely by the positions of the points and their types. The path behaves very similar to a springy rod which is forced to pass through the given points and which uses the minimum possible curvature to satisfy the requirement. As such, it feels quite natural and the resulting path is very smooth - with the kind of smoothness you can achieve with Beziers only after much tweaking. To create a Spiro path, select any path and assign the "Spiro spline" path effect to it. There are no parameters. Each node of your path becomes a point of a Spiro path, depending on the type of node: * Smooth nodes (those with two collinear Bezier handles) become curve points of the Spiro path; such points bend the curve but must remain smooth. Note that the length or direction of the Bezier handles of the source path is ignored; the only thing that matters is that the node is smooth. * Cusp nodes of the source path become corner points of the Spiro path. Between two corner points, the path is always a straight line. * Half-smooth nodes - those with one Bezier handle collinear with a straight line segment on the other hand - become "left" or "right" points on the Spiro path which behave exactly the same: they sit between a straight line and a curve and enforce that these two segments join smoothly without a cusp. Note that what matters is the actual collinearity of a node's handles, regardless of the node type that the node has in the Node tool; for example, if a cusp (diamond-shaped) node has collinear handles, it will become a curve point of the Spiro path. For creating half-smooth nodes, use Ctrl+dragging of the node handle to make it snap to the direction of the straight line segment on the other side, or press Shift+S to lock it to that direction. Some configurations of points do not converge and produce wild loop and spirals instead of a smooth curve. According to Raph, "The spline solver in this release is _not_ numerically robust. When you start drawing random points, you'll quickly run into divergence. However, "sensible" plates based on real fonts usually converge." Avoid too sharp changes in direction between points to prevent divergence. Hopefully, the robustness of the algorithm will be improved in future releases. For now, to edit Spiro paths viewing the result in real time, you have to use the Node tool. The Pen tool does not yet allow you to preview a Spiro as you draw, although you can paste the Spiro effect on the path and see the result as soon as the path is finalized. You can always use the Node tool to continue a Spiro path by duplicating and dragging away its end nodes. Also, when you have a Spiro path selected, you can add a new subpath to it with Pen or Pencil if you start drawing with Shift. Raph: Thanks for your code, and let me know when you have a new version :) I have copied only spiro.c/h and bezctx.c/h to Inkscape tree, renaming .c to .cpp and removing debug output, but otherwise unchanged. -- bulia byak Inkscape.

envelope LPE
by bulia byak 19 May '08

19 May '08

Thanks to whoever added this, it's fantastic! I have one request though: can you please combine the four envelope paths into one four-sided envelope? It will be much easier to edit this way. I understand that this may introduce the ambiguity as to where one side of the envelope ends and another starts, because the envelope sides may be more than 2 nodes long. But I have a rough idea on how to handle this: Imagine a line that goes at 45 degrees from SW to NE, and imagine that that line moves from infinity in the SE direction. The first node of the envelope path that it touches will be considered the top of the left side and the left end of the top side. Same for finding the 3 other corners. I think it will be relatively easy to implement - and much easier to use than the four separate sides. Thanks again, and by the way please add a description of the new feature to http://wiki.inkscape.org/wiki/index.php/ReleaseNotes047 -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

LPEs/paths and knotholders
by Maximilian Albert 18 May '08

18 May '08

Hi, I was experimenting with additional knotholders for items carrying an LPE but I'm having problems. What I did was simply to add another case distinction to sp_item_knot_holder() in object-edit.cpp. It checks whether an object has an LPE applied to it, in which case it returns a different knotholder than the standard one. The handling methods for the new knotholder are minimal (a 'set' method which does nothing and a 'get' method wich just returns a constant point) but Inkscape keeps crashing when handles corresponding to the "ordinary" knotholder are moved. I suspect that the new knotholder somehow interferes with the one that is created for paths in nodepath.cpp but I can't seem to find the exact cause of the problem. The backtraces don't look very helpful to me either since the crash happens in different places and I haven't yet found the common cause (see below for 2 sample backtraces; note that the line numbers may slightly vary due to my changes to the code). I wonder if anyone has an idea what could be wrong. Really some kind of interference between the two knotholders? How do the knotholders for paths work anyway? Is object-edit.cpp the wrong place to alter them?

Yes, I believe that all of the patches made it into the trunk. However, I don't think that any of them applied to Poppler. This sounds like simply a typical common regression here. ^^ We haven't done a "debug" upload in a few weeks.

Do I understand that your design for Pango will not call the render_glyph_func at all, i.e. we can leave it as NULL until we've figured out how to do things properly? Richard.

What other backend > do you have in mind? pangoft2? Inkscape really should just use the > cairo backend. Many cool new features (like vertical text support) are > only implemented in the cairo backend. OK, I was just trying to figure out what our options were. Of course Inkscape should be using the Cairo backend, we just don't at the moment. The difficulty we're having is that not enough of Inkscape's rendering has been converted to Cairo for it to be easy for us to use Cairo's user-fonts for output. Do you think it would be possible for us to create a fake Cairo user-font which only has a partially-implemented render_glyph_func (returns the extents but doesn't draw anything) and then we figure it all out later and send it to our own renderer? I'm just looking for a more incremental approach to this feature rather than having to bundle in a complete Cairo conversion at the same time. Changing the subject slightly, I can't see any mention of kerning in the current Cairo API. Is this something for later, or am I just ignoring things right in front of me again? Richard.

Request for translation SVN commit rights
by Domas Jokubauskis 14 May '08

14 May '08

Hello, I have been using Inkscape for a couple of years now and it have been a great experience. Thank you! I'm passionate about getting proper Lithuanian language user interfaces so I did a substantial update of Lithuanian Inkscape translation for version 0.45.1. I would like to continue my work on future releases but sending changes to the mailing list and asking others to commit them is counter-productive. Thus, I would be grateful if the project's admins granted me the permission to commit changes to lt.po file. My SF.net e-mail: domasj@...58... -- Domas Jokubauskis DomasJ@...1970...

I am working on nr-arena-glyphs.cpp there, at line 468: NRArenaGlyphs *g = NR_ARENA_GLYPHS(child); g->glyph holds an integer (the glyph id). As I understand it, there must be a mapping between a unicode char and its respective glyph id. How can I retrieve it? Juca

Reading through that bug I'm unclear whether the proposed pango_font_description_set_domain() function could be used to support a user-font which wasn't also a Cairo user-font. Could you clarify whether it intended to be able to use this feature without being required to use Cairo? Richard.

buildtool again
by Bob Jamison 13 May '08

13 May '08

Hi again. I left something out of buildtool yesterday, that broke the cross-compiler build on a linux box. Buildtool was not handling recursive substitutions, like: a = "Hello, ${b}" b = "earth, the third ${c}" c = "planet" This is slightly more work to do at execution time than at read time. command="${archutil}windres" archutil="${arch}" arch="i686-pc-mingw-" ...was not working. But it's fixed now, and has that pleasant late-binding smell. Sorry if this broke any cron jobs out there. ALSO: Does anyone know what might be causing this warning? I was afraid to touch it: http://rafb.net/p/34eJBu54.html bob

Fwd: CSS fonts only?
by Gail Carmichael 13 May '08

13 May '08

Below are some excerpts from my conversation with the Pango folks. Not the whole conversation, but will hopefully help Juca out a bit with his project. Gail ---------- Forwarded message ---------- From: Gail Carmichael <gail.banaszkiewicz@...400...> Date: Fri, Mar 21, 2008 at 2:14 PM Subject: Re: CSS fonts only? To: cfynn@...240... Cc: gtk-i18n-list <gtk-i18n-list@...45...> Thanks for the responses, everyone. I just got into a busy spell at school again, but later on I will need to look into this more. It sounds to me that, basically, we shouldn't be using that PangoFontDescription structure in memory to represent our fonts? Unless that changes (either the options the structure can represent or the fact that Inkscape relies on it so much), we will be stuck with the fonts it can represent. I will probably be back more a bit later to ask questions :) Gail Christopher Fynn wrote: Gail Carmichael wrote: Hi Christopher (and others)! Basically what I am saying is that the enumerations defined here <http://library.gnome.org/devel/pango/unstable/pango-Fonts.html><http://library.gnome.org/devel/pango/unstable/pango-Fonts.html>, like the variant, for example, have a specific subset of values. I just happened to notice that the defined values are pretty much equivalent to allowable CSS text attributes. In Inkscape, we use the PangoFontDescription pretty extensively. It is how font information is stored in memory while the program is running, for example. The problem is that some fonts have, say, a swash variant, which cannot be described with CSS text attributes, and also cannot be described with any of these enumerations in Pango in terms of the PangoFontDescription. Instead, the regular face of a font family is used (as a default fall-back), and "fancy" fonts are thus not accessible in Inkscape. Gail My guess is the best way to handle this w Pango would be through OpenType features & lookups i.e. to include the swash variant glyphs in the base font and have those accessed through OpenType features and lookups - which could be either contextual or user selected. Having *separate* alternative "fancy" fonts with swash / small caps / etc. fonts is the old way of doing things - if you think about it that way, is much more limited. For user selected / discretionary OT features the application (Inkscape) would need some kind of interface /menu through which the user could apply the features she wanted to. WRT CSS - there has been some serious discussion off and on over several years (on the OpenType list, CSS related lists and other places) about specifying - or applying OpenType features through CSS. regards - Chris Hope that clarifies what I am trying to say. It would be cool to pretty much just add more values to the enumerations (and supporting code) so more varieties of fonts could be described. I wanted to know what you guys thought of that possibility - is there some technical or philosophical reason, as can sometimes happen, for not doing so? Thanks Gail ------------------------------ *** VIRUS SCANNED by FASTLINK ISP ***

Update to buildtool for win32
by Bob Jamison 13 May '08

13 May '08

Hi, all. Over the weekend, I noticed a big flaw in Buildtool. The property aliasing, such as: path="{$gtk}/lib" ...was done at file-read-time. This made it impossible for a Task to use the results of another task as input. So all of the Tasks were recoded to have late binding. Package-config now works. To query a package, just use ${pc.packageName} for the 'all' query, ${pcc.packageName} for the 'cflags' query, and ${pcl.packageName} for the 'libs' query. Note that this is processed internally, and does not call the pkg-config executable. It also grabs all dependent packages' queries, too. This is in addition to the existing: ${env.VARIABLE_NAME} to fetch an environment variable. I did a test build, and it seems to work ok. Please let me know if there are any problems. After you svn up, you will need to do: g++ buildtool.cpp -o btool.exe ...again, for btool to use build.xml properly. bob (ishmal)

CSS for SVGFonts
by Felipe Sanches 12 May '08

12 May '08

During this weekend I have spent some time coding parameter loading for the font-face tag. Then, after commiting (http://inkscape.svn.sourceforge.net/viewvc/inkscape?view=rev&revision=18594), I noticed that style.{cpp,h} contain code that partially implements the same thing. So, I supose that I will have to revert what I did and use face->style to access the content of those attributes (such as font-style, font-variant, font-stretch, etc). Although, I have also noticed that not every attributes described on CSS2 spec, section 15 (Fonts) are implemented. For example, none of the attributes on section 15.3.6 ('panose-1', 'stemv', 'stemh', 'slope', 'cap-height', 'x-height', 'ascent', and 'descent') seem to be implemented. What should I do? Should I implement them in SPStyle? Or should I implement it on SPFontFace ? Juca

feature request, XY lower-left vs center toggle
by qazxswedcvfrtgbnhyujmkiolp2000 qazxswedcvfrtgbnhyujmkiolp2000 12 May '08

12 May '08

Hi inkscape-devel, A very useful feature for me (and probably others) is to toggle the meaning of the X and Y boxes between object lower left coordinate and object center coordinate. For example, just as there is a padlock button to control whether W and H are locked, there could be an origin button to control whether X and Y are lower left or center coordinate. I want this e.g. for positioning centered text by center coordinate, not lower left. What do you think? qazxswedcvfrtgbnhyujmkiolp2000

eraser tool feedback
by MenTaLguY 12 May '08

12 May '08

After experimenting with the eraser tool a little bit, I think the best answer to my use case would be to expand the tool to three modes, something like: - Delete - Erase from selected - Erase from all [i.e. all on current layer] Additionally, the tool needs the ability to "reach into" groups when erase. Currently it just leaves the erasure path behind without doing anything if you try to erase a group with paths inside. Also, the dynamic stroke features aren't very useful for erasure, which benefits most from a uniform, controllable shape. -mental

Inkscape 0.46 binaries / Zero Install
by Thomas Leonard 11 May '08

11 May '08

Hi, I normally add a link to an Inkscape binary (either the RPM or the Autopackage, whichever turns up first) in the Inkscape Zero Install feed: http://0install.net/2006/3rd-party/Inkscape.xml However, there don't seem to be any Linux binaries this time, so I have added the source to the feed and compiled two binaries myself (x86 and x86_64). These can be run using this command: 0launch http://0install.net/2006/3rd-party/Inkscape.xml The correct binary for your platform will be selected automatically (ensure "Help test new versions" is on, or you'll get 0.45). The 0launch command is provided by most Linux distributions, or you can get it from: http://0install.net Alternatively, you can use the binaries without using 0launch by going to the web-page above and clicking on one of the download links. The binaries are compiled with binreloc on, so you can run them directly after unpacking. I've tested them on Ubuntu/Hardy, but I don't know if they'll work on anything else. To choose a different version or compile from source: 0launch -g http://0install.net/2006/3rd-party/Inkscape.xml When compiling (right click -> Compile), Zero Install will download the headers for GTK, GLib, Pango, ATK, GTKmm and GLibmm automatically. However, some other libraries are not available this way and must be installed manually first as root, e.g. $ sudo apt-get install build-essential gettext libpng-dev libgc-dev libfreetype6-dev liblcms-dev libsigc++-2.0-dev libcairo-dev libcairomm-1.0-dev libxslt-dev libboost-dev libpopt-dev Hope that's useful! PS: The Zero Install feed is currently listed under "Development Versions" on http://inkscape.org/download. In fact, it only lists official releases, so it should be moved to "Official Release Packages". Cheers! -- Dr Thomas Leonard http://rox.sourceforge.net GPG: 9242 9807 C985 3C07 44A6 8B9A AE07 8280 59A5 3CC1

Temporary Bitmap Display Help in New Tool
by Keith 10 May '08

10 May '08

I'm busy developing a cool new drawing tool for Inkscape (one that I've been dying to implement since using Inkscape :D ), the core is pretty much finished, but I'm running into a bug which can be resolved by implementing a feature of the tool that I have no clue on how to achieve :( . My tool creates a GrayMap when the mouse button is pressed, updates it as the mouse is moved then processes and destroys it when the mouse button is released. I need to be able to show the GrayMap, any other kind of bitmap will do, on the canvas and then hide it when not used. How can I do this? I've been looking around and I can't find any examples in the existing code that does something like it. I'd really appreciate any help guys. Thank you.

not-set behaviour of some attributes
by Felipe Sanches 10 May '08

10 May '08

I am working on the parameter loading code for svgfonts. Some attributes of the font-face tag are specified to behave in special ways when not set. One example is this couple of attribute: accent-height = "<number>" The distance from the origin to the top of accent characters, measured by a distance within the font coordinate system. If the attribute is not specified, the effect is as if the attribute were set to the value of the ascent attribute. If this attribute is used, the units-per-em attribute must also be specified. Animatable: no. ascent = "<number>" Same syntax and semantics as the 'ascent' descriptor within an @font-face rule. The maximum unaccented height of the font within the font coordinate system. If the attribute is not specified, the effect is as if the attribute were set to the difference between the units- per-em value and the vert-origin-y value for the corresponding font. Animatable: no. Is there already a established good practice to deal with this kind of thing on the inkscape codebase? I suppose that a good solution would be to implement a container template-class which would take care of the set/unset state of the stored object (in these cases, a double) and a method to compute the nonset value, sometimes refering to the value of other objects. In these cases, it would refer to an ascent object for the computation of a not-set accent-height attribute and both vert-origin-y and units-per-em objects for the computation of a not-set ascent attribute. Am I right? Does this already exist on the codebase? Should I implement it this way? Juca

Nameclashing with is_finite macro
by unknown＠example.com 10 May '08

10 May '08

Hi all, I am having troubles with the is_finite 2geom macro. In Inkscape code, there are cases where an is_finite function is defined (proj_pt.h for example). This goes okay now, only because no 2geom headers are included before that header is included. If the isnan.h header is included before proj_pt.h, the compiler will place the is_finite macro in the function definition and compilation will fail. (on windows in any case) I see 2 options: 1. change the is_finite function name in proj_pt.h 2. change the is_finite macro name in 2geom/isnan.h to something less clashable Thanks, Johan
