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. Time to do another one, I guess. bob -----Original Message----- >From: J.B.C.Engelen@...1578... >Sent: May 14, 2008 8:10 AM >To: inkscape-devel(a)lists.sourceforge.net >Subject: [Inkscape-devel] PDF import crash, but not in 0.46 > >Hi all, > >PDF import crashes for me on Windows with current trunk.

Program too big to fit in memory
by Marcin Floryan 16 May '08

Hello! On today's compile of Inkscape (XP, SVN 18630) I got an unpleasant surprise. My system complains: Program too big to fit in memory with inkscape.exe being 224,113,108 B Although I have 2G of RAM I might have starved my XP of it a bit running quite a few programs already but nevertheless... are we going towards a boundary (or is it just my compilation).

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.

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.

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...

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?

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

Win32 devlibs in Subversion
by Bob Jamison 09 May '08

09 May '08

Hi all, In grateful appreciation to ACSpike and his friends at Modevia.com for their continuing altruism and generosity, I want to inform people who are using the devlibs that we finally have the devlibs served via Subversion. The devlibs are now available here: https://svn.modevia.com/inkscape/devlibs However, to keep bandwidth down, I beseech people to get the 7zip of the repository: http://inkscape.modevia.com/win32libs/devlibs-2.12-svn-0805081735.7z Unzip that as your initial working copy, then do svn updates after that. Yes, it is huge (117mb), but it is not as bad as a 300mb svn checkout. So in the future, when there are changes to the devlibs, all you need is an occasional "svn up", and no more monolithic downloads. By the way, I have a question: do we still need to have Perl in the /devlibs? bob

Re: [Inkscape-devel] [Lib2geom-devel] GSL dependency
by Bob Jamison 08 May '08

08 May '08

So we have a couple of weeks to get this ready, then? :-) But a little bit of lead time is always nice, so that we are not always trying to catch up with the dependencies, or worrying that the build might break because of them. Actually, I built gsl-1.11 this morning, http://inkscape.modevia.com/win32libs/gsl-1.11-mingw.tar.gz and uploaded it to the rsync repository. I don't know if that directory is anon rsync downloadable yet. But maybe we can change our mechanism for the .7z's in the meantime from how it is now -- me manually zipping and uploading. Merely 7-zipping the rsync/develibs dir on the server would be much more efficient, and less of a pain. And we have an older version (1.8) from 2 years ago in the win32libs dir, too. -----Original Message----- >From: Aaron Spike <aaron@...749...> >Bob Jamison wrote: >> But I must have missed the heads-up for the new dependency in the mail list. > >No you didn't miss it.

So I'd like that GSL becames a hard dependency, but obviously I'm open to alternative solutions. Implementing these tools by myself could be a solution but it wouldn't be a little effort. So if there are real points against making GSL a hard dependency I'd whish to know them as soon as possible.

GSL is a well established numerical library with really good performance and it supports a lot of platforms. We can't hope to find one library that perfectly fits our needs, and I suppose that we all agree that is not useful to reinvent the wheel. There are problems that own both a geometric and a numerical aspect, and 2geom should offer a specific implementation for these problems, but not for basic numerical algorithms. So, how much should we exploit GSL ? As little as possible but not less. Moreover, I like the idea to make up some wrapper for the needed functionalities, so weakening the source code tie with the library.

I don't know what you have in mind precisely about "the simple animation plan", but here are the main possible goals I see: * implement the svg animation elements : animate, set, animate{Motion|Color|Transform} * figure out a decent UI for editing animations: - a time-based (SMIL oriented) timeline editor to represent / move around keytimes (=keyframes except it's not frame-based but time-based) - an interpolation curves editor * design some animation-related on-canvas items, like: - trajectories (motion-paths) - temporarily overlayed (t-epsilon) / (t+epsilon) state of an object (to mimic onion skinning) Is that close to what you thought about ? There are a lot of open questions, like: - should there be an "animation mode" where the animated attributes values are edited, as opposed to a "normal mode" where it's the object attributes that are modified ? - SMIL semantic is quite rich: at first some things might be discarded like repetition or the possibility to define the start of an animation based of some events (e.g. user click or the end of another animation). Those things don't map well in a timeline UI which I guess is the way animators are used to think. - will the canvas scale well to preview large animations sufficiently smoothly ? Comments welcomed ! regards, Christophe

NEW: change in Transform dialog
by bulia byak 06 May '08

06 May '08

Previously, the Apply to each object separately checkbox had no effect for the Move tab. Now, if several objects are selected, this checkbox is on, and "Relative move" is on, each object is shifted relative to the closest selected object on the left (for X) or below (for Y). For example, if you have a horizontal row of objects and you move them relatively by X=5px with "Apply to each object separately" on, the leftmost object will shift by 5px, the next one to the right by 10px, and so on; the rightmost selected object is displaced by 5*n px where n is the number of selected objects. As a result, the distance in each pair of adjacent objects will increase by 5px and the whole row will be spaced out, much like a letterspacing adjustment spaces out a text string. Moving these objects by X=-5px will, conversely, squeeze them tighter together: the leftmost will move by -5px, the next one by -10px, and so on. For Y, the effect is the same except that the move starts from the object closest to the bottom (i.e. with smallest Y coordinate). When determining the order of shifting objects, for X, the left edges of their bounding boxes are sorted horizontally, and for Y, the bottoms of their bounding boxes are sorted vertically. Order of selecting the objects or z-order does not matter. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

SimpleCrosser
by Diederik van Lierop 06 May '08

06 May '08

Hi, Maybe it's just me doing something wrong, but I cannot get an intersection with the _closing_ segment of a rectangle. The first three segments between the four points of the rectangle behave as expected and do intersect nicely, but it looks like the closing segments is discarded when using the SimpleCrosser(). Is this by design or a bug, or am I missing something? This behaviour introduces a bug in Inkscape's snapping mechanism. For a constrained snap, I need to find an intersection of a linesegment (in the direction of the constrained handle movement) with an arbitrary path, but this doesn't work for the closing segment.

Drawing algorithm
by Tom Moore 05 May '08

05 May '08

Hi to everyone in the development mailing list - this is my first post, so sorry if I'm not asking the right people. I use Inkscape on a regular basis and have always been really impressed with the freehand drawing tool, specifically the efficient resulting curve (very few points to describe the curve). Does anyone know if it is viable to write a similarly efficient algorithm in Flash using ActionScript 3? I've given it a go on a number of occasions over the past 6 months to decent effect, but not half as impressive as Inkscape. Because ActionScript and Flash are pretty slow compared to C, I tend to use fairly simple algorithms to draw curved lines through points. I can only assume that the Inkscape algorithm is pretty sophisticated and I can't begin to try and work out how it was written from the svc, having had no experience with the language. Has there ever been any documentation, high-level schema or flowchart produced to explain the steps taken to calculate the optimised curve? I'm sure that someone must have produced some pseudo code or white paper to describe the best practice for a vector line drawing tool. If anyone has any ideas I'd be really grateful. Tom

Newest go-ooo.org has built in SVG support
by rygle 04 May '08

04 May '08

Don't know if you know about the community built version of OpenOffice.org, but it's at http://go-ooo.org. It boots quicker than the standard OOo, and has a few other great enhancements, like apparently now the ability to import SVG's directly. Still haven't tested this, as it's a 130Mb download, but the previous go-ooo.org version was noticeably quicker than the default on my computer, and a little more stable too I think. Any comments?

Batch export feature idea/request.
by Brian Vanderburg II 02 May '08

02 May '08

I have a set of several objects I'd like to batch export. I export them all to a single directory. To have multiple color sets I have a few key items and all of the objects are updated (mostly clones/etc), but then the problem is that batch export wants to write over the previous files so I must manually specify new files: directory layout: items.svg red/item1.png red/item2.png red/item3.png blue/item1.png blue/item2.png blue/item3.png etc With batch exports, after I save the red items and then change the key items to me the stuff blue, batch export still wants to save as red/item?.png A simple solution is in the batch export dialog provide an additional option 'Batch export to directory: '. When enabled, any existing export directory information would be ignored and only the filename portion of the exported file would be used, or if not available the object id. Then I can make the items red, batch export ,select 'Put all files in dir' and choose 'red' for the directory and export. Then change the key items to make it all blue, batch export but choose 'blue' as the export directory, etc for other colors. Something like the attached image Brian Vanderburg II

Re: [Inkscape-devel] Buildtool -- new
by Bob Jamison 02 May '08

02 May '08

When you say "btool something" that something is one of the targets in build.xml. The project has a default target listed at the top (dist). This is the one that will be executed, after all of its dependent targets, unless you specify another one. You can pick any target to execute. So you can say: btool compile ...and only run a compile, with no linking or copying. I guess you could add a pair of targets, something like this: <target name="refresh_prepare" description="delete the build.dep file to force a regeneration"> <delete file="build.dep"/> </target> <target name="refresh" depends="refresh_prepare,compile" description="force the cc task to regenerate its cache">  </target> The second task doesn't need to do anything. It just says: "before me, run refresh_prepare, and then compile" I'm not sure how to work that into the scheme of the rest of the target hierarchy, though. :) bob -----Original Message----- >Nice, > >Can you alias that, so that -Drefresh=true is just refresh, so you can >simply go 'btool refresh'? >

Re: [Inkscape-devel] Buildtool -- new
by Bob Jamison 02 May '08

02 May '08

Just a reminder, for when you do an "svn update". If, in the left column, in addition to U and G, you see any A or D for added or deleted files, then you will need to regenerate the dependency list. Also, at link time, if you see errors about missing symbols, then you probably have too many or too few .o files in the /build/obj directory. This is another clue that you need to refresh the dependency cache. The "clean" target has a task for deleting build.dep, so "btool clean" always works, if all else fails and you need to take drastic measures. Another trick: if you need to force a rebuild of a certain set of files, but don't want to rebuild the whole tree, then look in /build/obj. The directory structure mirrors /src. Just delete the corresponding .o's and run btool again. bob

Buildtool -- new "refreshCache" flag
by Bob Jamison 02 May '08

02 May '08

After thinking about telling Rygle about deleting build.dep to force a recomp, it occurred to me how kludgey that is. So I added yet another flag to the <cc> task, refreshCache="true/false". Setting this to true will force a regeneration of the cache. But you say "Hey, I don't want to edit build.xml every time I want to clean the cache!" Fair enough. So I added another property to build.xml, "refresh=false". This value is used in the <cc> task as refreshCache="${refresh}" To change this, and force a refresh, merely redefine "refresh" on the command line: btool -Drefresh=true You should see this near the top of the output: overloading property 'refresh' = 'true' This is a workaround to the problem: how to specify a task-specific parameter on the command line. I need to figure this one out eventually. By the way, did you know that you can do this? Calling btool this way: btool -Ddist=c:/inkscape ...sends the completed Inkscape distro directly to c:\inkscape :) Since btool uses URIs, "\" or "/" doesn't matter. Let me know if you have any problems. But this is a good example of how btool can be modified, and new Tasks added, to perform whatever build functionality we need. bob

New Extensions and Translation or other requirements
by rygle 01 May '08

01 May '08

Hi, Inductiveload has been busy fixing and making extensions. The version of Add Nodes in trunk can now divide into a given number of segments (see LP#171856), and there is also now a Render -> Polar Grid option in trunk (see LP#224522). Soon there will also be a Render -> Cartesian Grid extension, but that's got a slight problem being sorted (see LP#224955). I've recently added the new files to /share/extensions/Makefile.am - I realise that affects the Linux (Mac?) build process, even if it doesn't affect Win32. Does /share/extensions/Makefile.am also flag files for translation (seems to hint at that)? If not, is there a need to change something else for translations? Is there anything else that needs to be updated for new extensions? Cheers, Rygle. -- View this message in context: http://www.nabble.com/New-Extensions-and-Translation-or-other-requirements-… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Release wardens impose marshal law during release times to make sure things get out the door in a reasonable amount of time and without any avoidable nasty bugs.

I think sometimes applying a patch assigned to another person could possibly maybe tread on another person's toes perhaps. This time it didn't. I grabbed this patch because the author had written me individually about the change and because there doesn't seem like a lot of people who want to deal with python patches. But I knew that I wasn't going to get around to committing it until the weekend and it is very important to have quick turn around on patches. This shows that we value the work being done and encourages repeat contribution. Just think how discouraging it is when I sit on a two line python patch that is obviously fine. You're timing was excellent. Feel free to commit a patch. As long as you do due diligence. Meaning: You understand the issue it addresses. You test it locally to see that it does address that issue. You do not notice any major regressions as a result of it. Otherwise ask for a little clarification and help. And if you feel comfortable, go ahead and assign bugs to yourself. :-) And, yeah, it probably doesn't hurt to ask if the bug is assigned to someone else. I know in my situation sometimes I don't comment everything I know on the bug because I don't think of it. There might be some issue I want to check into. So if you ask I'd be more likely to write that in the bug comments. Not trying to hide info; I just don't think of these things all the time. Thanks for applying this patch! Aaron P.S. I'm copying Inkscape-devel to give people a chance to disagree with me. :-)

New tool added
by Jon A. Cruz 01 May '08

01 May '08

I've just committed the first cut of the new eraser tool. This first part only adds in the functionality to cut away parts of objects you have selected. It won't do anything if you don't have something selected, and it won't do anything if the first mode is selected (the sub-toolbar has toggles for the two modes). However it does commit all the infrastructure changes including the new icons, new drawing context, verbs, switching, etc. I had been wanting to get that in first to shake down bugs in that support work. Hopefully I'll be able to get the other mode committed this weekend. That's the main differentiator and works like touch-delete or perhaps pop-the-balloons. Please let me know if there is anything in that commit that needs fixing, etc. etc. Thanks.

GSoC tag-team for lib2geom integration
by unknown＠example.com 29 Apr '08

29 Apr '08

Hi all, Yesterday I had a chat with mgsloan about lib2geom integration for GSoC'08. We spoke about working together on it. He knows 2geom very well, I know Inkscape well and have worked with 2geom a lot for LPE. Because complete conversion to 2geom is a big task, where 2geom issues can become apparant, I think it is nice to have a 2geom developer working on it aswell (although I did commit some small things to 2geom, I do not count myself as a real 2geom developer). This way, we can both work and discuss things where we are uncertain. I hope to have a somewhat longer discussion with mgsloan within the next couple of days. How do people feel about this? Apart from having a 2-man team on lib2geom integration: I know I have been very brief in my gsoc proposal as blueprint. I am thinking about 1. writing test code (cxxtest) 2. integrating lib2geom in steps, for example per tool or per feature 3. switching to 2geom path representation in inkscape core is advanced task and should be tried later in the project 4. I'd rather *not* work in a branch, because then people that code new things will use 2geom instead of me/us having to recode new things to 2geom. (conflicts etc abound) 5. Release lib2geom after integration is complete. Not before integration is complete because of things that might be missing or bugged in 2geom. Thanks for your opinion, Johan

Win32 0.46.1 patches
by rygle 29 Apr '08

29 Apr '08

Hi guys, Just letting you know I've moved all previous Win32 patches for 0.46 to /packaging/win32/patches/0.46, and created a new 0.46.1 directory, just to keep things neat. Bryce and others have expressed concern about linux distros getting narky about unnecessary bug fixes, hence keeping the Win32 only patches separate. That way we can fix a bunch of stuff that was still broken in the win32 0.46 release and not bother the linux distro people at all. All these patches should already be in trunk, and so should automatically make it into 0.47 without remaining separate (I think). The Mac guys might like to do the same ?? Can we keep milestoning bugs for certain releases (unless they're not likely to be solved by 0.47) - with only bug fixes of existing features being marked of 0.46.1. Can we also start adding patches to the win32 0.46.1 section for stuff that's been tried in trunk? I've committed two patches that were in trunk, but there are a bunch more out there already.

new SVGEllipticalArc implementation merged into path.h
by Marco 29 Apr '08

29 Apr '08

I merged my implementation of the SVGEllipticalArc class into path.h substituting the old one. Some method lacks of a native implementation, yet and it relies on a conversion to SBasisCurve, but the class is fully working (there isn't any not_implemented exception thrown any more). Moreover I commit a new version of the svg-elliptic-arc-toy, with the ability of testing the portion method too. PAY ATTENTION ! I want to point out that I modified the src/CMakeList.txt file, adding some line of code in order to find out which version of ragel is installed. This is needed because starting from version 5.18 the ragel package substituted the command rlcodegen with the rlgen-cd command as specific code generator back-end for C, C++ and D languages. If you'll get into troubles when you build the library you'd look that you have the ragel package installed. Anyway in case of problem you can send me a mail or contact me on the lib2geom channel.

It's probably going to be close to that. Bbyak had already been working on such an additive and subtractive options for the calligraphic tool. There's a bit of a difference in some use cases, and it will be diverging more. From what I can see of things, though, the calligraphic tool will be very useful for a different set of operations. > An other thing; it would be really cool to be able to auto switch > to the eraser tool when using the eraser of a wacom tablet. Eeek! You got me! :-) Actually with the code in SVN it should be able to do almost that already. It should be detecting input devices and switching to the last tool used with a given device (tablet mouse/puck, stylus front, eraser back), so once you use the eraser end and use it to pick the eraser tool, it should switch tools as you go. I've just not tested that again recently since I'm on my box running Hardy and that has some wacom issues. And thanks for reminding me. I'll make that tool the default for any "ERASER" type extended input device.

Inline Function Removal
by Jimmy 28 Apr '08

28 Apr '08

I am currently working on Inline Function Removal and while replacing calls to sp_repr_set_attr with direct calls to the wrapped member functions I noticed that the wrapped function is defined as void. There are tests that are run to check if sp_repr_set_attr fails. sp_repr_set_attr always returns true although I suspect this was designed to change at some point If sp_repr_set_attr is replaced in one of these tests for example: /// \todo fixme: Exception if object is NULL? */ if (!sp_repr_set_attr(object->repr, key, NULL)) { No value will return and the compilation will fail. Should I just comment out these tests or remove them and leave the todo? As of now the tests just accept true from sp_repr_set_attr and they don't actually check anything. Jimmy Varvaro

NEW: Filter Effects
by Ted Gould 27 Apr '08

27 Apr '08

Hey, So I subclassed the effects to provide an easier way to just add filters on a group of objects. Hopefully bringing this into the realm where anyone who understands the filter dialog could build their own filter effect. It needs to documentation and overall is less than complete, but I thought I'd put it out there for people to play with. I took all the examples from Mauve's excellent example file[1] and turned them into effects on the effects menu. Now you should be able to just grab and object and apply these to your objects. To create your own I suggest copying "sepia.h" in /src/extensions/internal/filter and replacing the strings. All you need is a non-translated name (ID), Menu name, description and then the filter that you want to apply. You'll then need to add it to "filter-all.cpp" but that is also pretty straight-forward. If someone isn't faster, I'll make better docs. [2] It is a little more difficult to use parameters, but not that hard. There is one example of that, drop shadow, which of course works with live-effects also. I would also like to clean this up and make it easier. The biggest limitation of the implementation right now is that it will ONLY apply if there isn't a filter on the object currently. Long term, I'd like it to merge the filters. That's all for now! --Ted [1] I didn't take Drop Shadow from there because I was looking at the SVG file and the filter for Drop Shadow is above the linear gradient where I started looking, so I missed it. No seriously, stop laughing. [2] I would like for someone with a light programming background to do this as they're likely not to skip over things that other people would need to get started.

Buildtool -- new "continueOnError" flag
by Bob Jamison 26 Apr '08

26 Apr '08

Johan asked me to look into a way of having buildtool continue processing files after a compile error happens on a file. Although going to the next task after a failure would be incorrect, there is nothing to stop us from letting the <cc> task continue processing its file list after a compile failure. So now there is a new attribute for <cc>: continueOnError="true" which will allow the <cc> task to proceed with its file list after an error. At the end of processing the list, it will return failure as before. If you want to use this feature, just set the flag to true, and read the "compile.lst" compiler listing file after buildtool is done. By the way, everyone should read compile.lst occasionally, even when builds are successful. Warnings are listed there. bob

Toolbar icon sizes

The preferences for the toolbar icon sizes has been changed from a simple toggle of two sizes, to a combo to allow for three sizes. Also, all three toolbars are now configurable. This fixes a problem many users, especially Ubuntu users, were seeing on monitors that only went to 1024x768 or smaller. Things should not affect anyone's existing preferred setup, and should take manual intervention to see a difference in the UI.

converting to C++, helper script
by unknown＠example.com 25 Apr '08

25 Apr '08

Hello all, In my branch (gsoc2008_johan_path2geom), I've been converting SPCurve to a proper C++ class. A lot of the work involves replacing "sp_curve_moveto(c, p);" to "c->moveto(p);" . I've written a script to do this kind of thing. If anyone wants to move more to C++, I think you'll find this automation very handy. Basically, the script searches for a certain regexp, and replaces it with another. There is a confirmation check on every occurance, because the replacement might go wrong (in my script "sp_curve_moveto(human->arm().fingerpath, p);" is incorrectly replaced with invalid code). I have added the file to our wiki. Do we have a page about converting to C++? I'd like to move my SPCurve C++ify to trunk, I have tested and there seem to be no bugs. Can I proceed? Cheers, Johan

"Stack Stroke/Fill" effect for Inkscape
by Ove Kaaven 25 Apr '08

25 Apr '08

Hey, I just subscribed to this list. I've written an effect for Inkscape in Python, and if you like it, it'd be nice to see it included in the official Inkscape. I've explained what it's supposed to do, with screenshots, here: http://www.ping.uio.no/~ovehk/inkscape/stack.html Comments welcome. Perhaps I should call it something else (I just called it "stack" because it kind of stacks the stroke on top and the fill on the bottom), and perhaps there's a better way to do what I'm trying to do. (Also, it'd be nice if there was a better tool for brushing out blobs than that calligraphy+union trick I used there...) <inkscape-extension> <_name>Stack Stroke/Fill</_name> <id>org.ekips.filter.stack</id> <dependency type="executable" location="extensions">stack.py</dependency> <dependency type="executable" location="extensions">inkex.py</dependency> <effect> <object-type>all</object-type> <effects-menu> <submenu _name="Generate from Path"/> </effects-menu> </effect> <script> <command reldir="extensions" interpreter="python">stack.py</command> </script> </inkscape-extension>

Extensions (inx) files
by Marcin Floryan 25 Apr '08

25 Apr '08

Hi! I was playing with some extensions recently and started wondering that it would be nice if the extension files (inx) could be made into properly formatted XML documents with their own namespace and an XSD to come with it. This should make creating new ones easier as well as validating them. I should be able to carry out all necessary work but wanted to know if you guys think it is sensible...

Re: [Inkscape-devel] FUN: a weird clock in SVG+javascript
by Alvin Penner 24 Apr '08

24 Apr '08

Okay, I have to admit, that was EXTREMELY COOL, I didn't know that SVG could do animation. But now, being a Windows user, I have a question, this animation runs very well using SeaMonkey in Windows XP, but if I use IE7 as I normally would, then I just get a static image, no animation, anybody know why (other than the obvious answer, that it was made by Microsoft) ?

FUN: a weird clock in SVG+javascript
by Felipe Sanches 24 Apr '08

24 Apr '08

I have just coded this javascript+SVG weird clock. It is composed by several clock pointers that together form words indicating the current time. This animation is obviously running faster than usual clocks, but I guess you get the idea. http://bighead.poli.usp.br/~juca/code/svg/javascript/weirdclock.svg I have drawn it using Inkscape and then coded it using gedit. I had some issues while doing it. One issue is that javascript code is escaped with html escape codes. This messes my code everytime I modify the SVG file using Inkscape. Another issue is the path:d attribute, which seems to use m and M path codes randomly . I hope you like my animation and that it helps improve inkscape in this use case: handling of SVG files containing javascript code.

use current drawing datas in Extensions (inx) files WAS Re: Extensions (inx) files

Would be extremely useful and powerful for extension designer, better than redesign the well each time an extension need a boolean operation or sthing else ! But what would be actually really useful for some projects is that we can use data taken from the current drawing inside an extension dialog. Just for instance, I want to design an origami diagram manager upon inkscape, where each step is stock in an svg:g with an id in a particular namespace. Writing an extension where I can manage the creation or removing of a step, open the new group in order to the step will be drawn inside it is really easy (I am on the finishing of this part) with lxml, but I would love to write another part to choose the step to edit, where the extension dialog let me shows all the step-id and title of the current drawing. I have think about delegate some parts of my project on another gui -tkinter or something else- when I need to use datas from the drawing, but something like : <xslt:for-each select="g[@oh:step]"> <option value="{./@id}"><xslt:value-of select="@title" /></option> </xslt:for-each> would be really really great.

GSOC branches
by unknown＠example.com 22 Apr '08

22 Apr '08

Hi all! I just heard the great news! Thanks for giving me this opportunity again! Congratulations Felipe, Marco, Jasper and Max! Special note to Max and Marco: since you do geometry things, I'd be happy to work more closely with you if possible and desired :) To Jasper: is it okay if I bug you about path tests? :) Really excited by the project ideas that were accepted! Now, to the topic of this mail: GSoC branches, yes/no. I will be doing under-the-hood refactoring, and I am thinking about whether or not to work in my own svn branch. Pros: I can break builds with partial commits and/or make bad bad bugs. Cons: I won't discover bad bugs. I'd like to work in trunk, because of the bugs issue and because it will force me to immediately handle new code by others. Moreover, I will be forced to make changes that build and function and won't be drawn into making a half-way solution that will not work at the end of GSOC. For the people that are afraid I will be messing up trunk badly: I first intend to do changes in the way the code accesses the path data, then make a test function for conversion to 2geom, then have both representations in inkscape at the same time and constantly check whether they are the same, etc. I intend to do small steps towards completely going to 2geom, so I am more sure that it actually works and did not introduce new bugs. Please let me know what you think of this. Cheers! Johan

GSoC and My Plans

Hey all, I just got the rejection letter from Google. I wanted to let you guys know that I will definitely try to make an effort and contribute a bit to the community anyway, but I do take this as a bit of a sign - it's the gods telling me I should work on my thesis as much as I can this summer ;) Hopefully I can contribute something to the conversation on SVG Fonts (assuming Felipe was accepted, but I think that's a safe assumption), and I know there are a good number of text bugs that might be a good place for me to spend short bursts of time. Congrats to all those accepted, and I hope everyone has a fantastic summer! Gail

Inkscape and the Hackontest
by Bill Baxter 22 Apr '08

22 Apr '08

Is anyone interested getting Inkscape into the the Hackontest? Seems to me like if registered, Inkscape would have a pretty good chance of being accepted. Inkscape has a large user base -- good for getting votes from the loyal Inkscape's purpose is easy to understand -- good for getting votes from people who've never even heard of it Inkscape is modular enough -- you need a project idea that can realistically be done in 24 hrs, and many things like cool new LPEs or exporters or importers could realistically be done in that time frame. Inkscape has a huge list of contributors -- important because you need to actually get 3 people willing to go to Sweeden and code for 24 hrs straight. I think Inkscape would have a good shot. --bb

X,Y,W,H settings do not change independently
by qazxswedcvfrtgbnhyujmkiolp2000 qazxswedcvfrtgbnhyujmkiolp2000 22 Apr '08

22 Apr '08

Hi inkscape-devel, I notice that when I want to draw an object with a particular X,Y,W,H this is not easy, because these settings do not change independently. For example, I want to draw a box 210x297 centered at 0,0 (i.e. W=210, H=297, X=-105, Y=-148.5). I make sure I am using geometric bounding box, and I draw the box by hand with a random size and position, then I enter these values in the W,H,X,Y fields. But when I enter some of these values, they change the other values slightly! Is this a bug, and is there a way to correct this behavior? Thank you, qazxswedcvfrtgbnhyujmkiolp2000

I asked if he'd create a bunch of stock filters for us to provide, as bulia mentioned a desire a while back for "easy filters". So, it's definitely a phenomenal start. But we also need to figure out how to implement the UI for easy filters. Just via menu options with no params? An "easy" dialog which hides the advanced bits? Or filter specific dialogs like the effects? Any other ideas? Unfortunately, the problem is that we now have figure out where some filter related issues lie. I tried opening up the file in Batik, but it sees it as invalid. Are we producing invalid svg, or is batik just really picky? Also, some filters render differently in Firefox 3 & Opera 9.5. So at this point, we shouldn't get overly excited until A) we're producing files batik likes (or we file a bug report with them if the problem is on their end) and B) we figure out who really has the most accurate filter implementation and either match it, or inform them if ours is "better". -Josh

Re: [Inkscape-devel] Extensions (inx) files - XML parser
by Bob Jamison 21 Apr '08

21 Apr '08

Just my humble opinion on how Inkscape reads SVG files, is to be very forgiving on input file parsing. In case of a minor format violation, try to correct it. Report the worst errors, of course. And then do Inkscape's best to generate clean and proper data. Thus, over time, Inkscape has a side effect of gradually mending a domain of broken files. A lot of editors do it this way. Do we want to reject an XML file if it is horribly munged? Sure. But if it merely needs a bit of tender care, then allow it. Then instead of merely telling users to fix their file, Inkscape does the fix itself. Use validation to tell people why their file has a problem. But don't always reject it.

While the "Live preview" checkbox is useful for most effects, for some it just does not make sense.

Bug triaging help needed
by Bryce Harrington 19 Apr '08

19 Apr '08

Heya all, Have you been enjoying Inkscape and wondering about an easy way to contribute back? Bug triaging may be for you! Bug triaging is basically our first line step in the process of handling bugs. It's like being the host in a restaraunt - you don't fix the bugs, you just make sure the reporter has been greeted and find where they should sit. You can see the problem we're trying to solve by just looking at this plot: http://people.ubuntu.com/~brian/project-graphs/inkscape/plots/inkscape-mont… Or, this one is less intimidating since it shows the progress we'd made prior to the release: http://people.ubuntu.com/~brian/project-graphs/inkscape/plots/inkscape-half… (There is a friendly navigation web thingee here: http://people.ubuntu.com/~bryce/Plots/) The job is to keep our total # of New bugs at as close to 0 as possible. We're up towards 200 now, so there's a bit of work to get caught up on, but once that's caught up you can see that there's a rate of about 3 new bugs/day. Triaging is pretty easy; anyone can do it - you just need to sign up for a launchpad bug account. (For extra triaging powers you can also join the Inkscape bug team.) Then you read each bug report that comes in, and make sure it has all the necessary information for developers to troubleshoot it. So for example, this may include asking people to include screenshots, steps to reproduce the issue, backtraces, and/or example files; then you set it to Incomplete state. Then, you also review bugs that are in 'Incomplete with response' and check if they've included the needed info, and move them into Completed state. You can see the bugs still in Incomplete state via the Plots link above. And that's pretty much it. If you are looking for a way to contribute some help to Inkscape that doesn't require an extensive time commitment, this is one of the easiest ways to make a difference. Plus it's addictive! You can track your "karma score" at this link: https://launchpad.net/inkscape/+topcontributors Getting yourself up into the top 5 is a good challenge if you have the interest and time to put into it. Karma degrades over time, so even if you're starting from 0 you have a chance to catch up and pass the long timers! Bryce

Problems with font selection toolbox.
by Marcin Floryan 18 Apr '08

18 Apr '08

Hi! There seem to be an awful increase, recently, in the number of bugs reported around the behaviour of the font family and font size selection toolbox in 0.46 (and it equally affects SVN as for now). There are also some outstanding Critical bugs - just some examples are: https://bugs.launchpad.net/inkscape/+bug/168161 https://bugs.launchpad.net/inkscape/+bug/168320 https://bugs.launchpad.net/inkscape/+bug/168719 https://bugs.launchpad.net/inkscape/+bug/183179 https://bugs.launchpad.net/inkscape/+bug/218502 https://bugs.launchpad.net/inkscape/+bug/218502 I know often this is associated with Win32 platform but I have seen those on Linux as well. What seems to cause the problem often is when the default font (or font applied to the text) does not exist. Would it not be nice, if one could enter any arbitrary font family name for a font and have Inkscape handle it gracefully. I would like to help with this issue (OK, I can even abandon my Linux for a bit to help on the Win32 platform) but I still know too little of the Inkscape codebase. But what seems to me like a plausible solution would be to reproduce the functionality of the Text and Font dialog in the font tool bar. I presume that many issues could be solved when SVG Fonts are finally implemented. Just wanted to grab some of your attention though no doubt it is already on the issue :-) Cheers, -- Marcin Floryan http://marcin.floryan.pl/ [GPG Key ID: 0D5581C5]

restack extension

Hi, We got a neat new extension by Rob Antonishen during 0.46 development cycle that for some reason didn't go into 0.46 after all.

Behavior of X,Y,W,H settings in the GUI
by qazxswedcvfrtgbnhyujmkiolp2000 qazxswedcvfrtgbnhyujmkiolp2000 17 Apr '08

17 Apr '08

Hello Inkscape Devel, Great software, big fan here. I notice that the X,Y,W,H settings in the GUI include the stroke width. i.e. if you have a 2,2 sized object located at 0,0 with stroke width of 0.05, the X,Y position reads -0.025,-0.025 and the W,H value reads 2.05,2.05. Using the grid can help, but technical drawing with this system is very difficult. Would it be possible to add an option so that X,Y,W,H settings refer to true object coordinates (like they are output in the SVG file), independent of the stroke width? Thank you qazx (qazxswedcvfrtgbnhyujmkiolp)

SoC Updates
by Gail Carmichael 17 Apr '08

17 Apr '08

Hi everyone, I mentioned in my app that I had applied to work with a colleague for Summer of Code (with Python Software Foundation) in addition to the text application I made to Inkscape. I also stated my intentions to try and work on Inkscape one day a week or so starting in the fall, meaning I would attempt to tackle the stuff of my app even without SoC. Still, I would like to participate in the official program if possible, since I can't justify working more than that one day a week otherwise (it's thesis time), no matter the project. I had promised in my app to keep would-be mentors updated on the progress of the other app. At this point, PSF has 50 projects with mentors, but only 30 slots, so it's hard to know what my chances are there, but duplicate acceptances have to be sorted out still. I think that happens by the 18th, which is the deadline that Aaron mentioned for ranking the apps. Also, I don't think I necessarily need a mentor with a lot of experience in text (i.e. Richard) but just with Inkscape architecture in general. That would ensure Richard would be available for Felipe's application without precluding me being able to do mine. I think all would-be SoC'ers would appreciate any feedback in terms of our applications, if anyone can give any :) Gail
