Illustrations for a planned 3D box tool (SoC)
by Maximilian Albert 26 Mar '07

26 Mar '07

Hi, I am planning to submit a proposal for the 3D box tool as a Summer of Code project. For illustration purposes, I have collected a few ideas and prepared some graphics regarding possible features. This is meant to get across how it would "feel" using the new tool. This "virtual tutorial" is still somewhat preliminary, but everyone who is interested is invited to have a look at it and make comments. Any input is highly appreciated. It can be found at http://www.rzuser.uni-heidelberg.de/~malbert/ Thanks for your attention! Max

SoC: Officially applied!
by Gail Banaszkiewicz 26 Mar '07

26 Mar '07

Ok, I've done it - I've officially applied through Google to SoC. My application pretty much just points to this web page so that I can update it as comments come in: http://www.scs.carleton.ca/~gbanaszk/code/soc07/index.htm If you read through the proposal PDF, you will see that I've tried to leave things fairly flexible. Hopefully this will be a key to success ;) Feel free to comment, good or bad! Gail

3D tools proposal for Inkscape (GSoC)
by The Pete 25 Mar '07

25 Mar '07

Hello, I was toying with some ideas for the 3D capabilities of Inkscape that will soon be developed. These ideas may have been floating around already, and I saw what the character Maximilian Albert proposed with the multiple Vanishing Points in his document for cubes in 3 space, and I figured it could be useful to apply to any style of primitive (such as cylinders, cones, etc...). Though, of course, with something such as a sphere, it would be rather awkward and pointeless, unless you consider an ellipsoid. Which could lead into the idea of incorporating the VPs and 3D ability with the use of Bezier curves, possibly making a sort of moldable surface applicable to cubes, cylinders, and other such primitives. Another possibility being toyed with is the extension of freehand drawings - drawing any shape (closed or not, and including the calligraphy tool), and giving it depth, to which vanishing points can be applied to. I'm not sure if these set of ideas would be considered over the top, or not in the direction the 3D project is aiming for. Of course, feedback and/or laughing is always encouraged. Thanks! -- -Peter

Hey Richard! I suppose the biggest question at this point, while I put together my proposal, is what items you have been wanting to fix, improve, or add to the text code but haven't had time to do. I'd love to get an intro to the text tool, but it may have to wait until after I (hopefully) get accepted, because as useful as it would be, applications to SoC are due tomorrow, so time is important. :) That said, I'm "wing-tip" on IRC, and should be there for a good chunk of the day today.

Fix for [ 1679367 ] no icon to justify text in dialog

My first bug is done and ready to go! It seems that I can't actually upload my patch as an attachment to the bug itself, so mental suggested creating a new entry in the patch tracker. Because I have never had a need for patches in the past, this is the first one I've made. As such, I'd like to have somebody double check that it worked ok before I officially upload it. http://gbanaszk.oasis.nexus.carleton.ca/SummerOfCode/patch-bug1679367.txt All I did here was add the justify button to the text dialog.

Re: [Inkscape-devel] Illustrations for a planned 3D box tool (SoC)
by Maximilian Albert 25 Mar '07

25 Mar '07

Hi Thorsten, finally a response from me, too. ;) Since Bulia already replied to pretty much everything you said/asked, I will just make a few general comments, trying to sum it up. I think I can understand your concerns very well, since until rather recently I shared your attitude. My first brainstormed attempt for a proposal used an approach very similar to yours. I asked myself who would use this tool and tried to tailor it to this target audience. The result was something which would probably have been quite usable, but mostly for people who want to draw 2-point perspectives with a horizontal horizon. Users who are interested in more complicated and/or unusual things like the second picture on the website could certainly use it, too, but with a lot more inconvenience since they would have to start with the restricted case. On the other hand, the more general 3D tool can with minimal overhead be made behave like one that was specially designed for 2-point perspectives. Bulia managed to convince me that it is much better to allow for maximal flexibility while preserving maximal simplicity. I think the described tool satisfies this. You can quickly draw any perspective you like. And if you are not perfectly satisfied, you can change it easily. The size of the box can be changed by dragging the corners (which makes them "glide along" the viewpoints, preserving the perspective). On the other hand, the perspective can be changed either by dragging the vanishing points or by dragging the perspective lines themselves. ==> My point was not about a technical limitation, but the common practical approach to drawing in perspective: you draw a box and the VPs remain in your imagination only. The angles of the edges step into the foreground. <== Hmm, after rereading your email I finally understood your objection. And on second thought I agree that it would probably be good to include an option which allows the user to drag PLs separately, without necessarily moving them together (as would be the case when using the method described in the third paragraph). On the other hand, what you have in mind essentially results in a rotation of the dragged PL around a specific corner and within a plane spanned by two of the VPs. I could imagine that in unusual perspectives it's not totally obvious which one that should be and how the user should be able to change it (in most cases, though, it will be the plane containing the VP for the "up" direction, which lies at infinity in the first picture, as well as the one on the PL being dragged). But I will give that some further thoughts, thanks for the suggestion! On third thought ;) your desired behaviour can almost be achieved using the method in the fifth paragraph. Just shift-drag the PL to constrain the movement of the VP to the horizon. This adapts the angle at the corner in a way which should be sufficiently intuitive. It certainly also adapts the angle at another corner, but that could be remedied (if required) by dragging the horizon when that is implemented later on (see below). As far as horizons and similar things are concerned, I agree that they make life much more easier for the average user, and I think we should provide the relevant functionality sooner or later. But in the beginning it is probably best to confine ourselves to the very basics and to make them work/behave properly and intuitively. Later on it's then no problem to add a horizon, make it draggable, restrict the movements of VPs to it, and many more things you could think of. But let's not attack these things before the core tool really works.

I remember doing some basic animation stuff with KToon but... What I think about KToon is that, the UI is bit strange (and wasting lot of pixel space), The brush tool is not has good has the inkscape one. And I don't think that we can find all that great stuffs that are in inkscape now like clone, linked clone, mask, blur, ... Even the node editing is far more advanced. It's the same problem about Synfig: lots of crash, strange UI and annoying flying windows. I just think that Inkscape have more chance to become an usable and powerfull 2d animation program first.

Right now, the there no opensource program to do traditionnal 2D animation or storyboarding like toonboom or flash... Inkscape could become a great tool for 2D animation. Here is a description of what need to be done: More important: -Add something to handel multiple draws/pages/frames (maybe trought the <mutlipage> svg tag?). -Add a timeline to handle keyframes and the duration of keyframes. -Add onion skin function. -Add realtime playback (temporary ram cache ?). -Add "export multiple frames" function. Secondary stuffs: -Improve the Brush/Calligraphic tool with automatic boolean function (like the one of flash). With that kind of option, it would be easy to add Eraser Tool... -Add an UI to handel different brush shapes/options. -Add a Cut Tool I would like to work on those area myslef to but with my actual coder skills, it would take years before getting something. So if you are interessed in those area, I'm sure you can make the opensource world for animators a better place ;) see you, Ronan

Thanks, So, in that case, I will make an application for the color adjustment dialog. I feel confident, having a clear idea of how that could work as a final result, although I would have to look at the source code to learn more specifics of the implementation (working with the gui, and adjusting the colors and properties of objects in Inkspace). Bulia, since you are the mentor for this task, when I have any questions, regarding the development, and how it would best suit the software and integration with your current code, do I send to your email, or to this mailing list?

Hi, May I introduce myself, My name is Omar El Sawi, I study Computer Visualization at National Centre for Computer Animation, UK. Unfortunately, I was late to hear about the Google Summer of Code Project. However, I have been using your software, and I would love to join. The "Color Adjustment Dialog" task seems suited to my skills. (I made a simple program last year with some similar functionality.) I'm thinking a dialog under (Effects -> adjust colours) which could interactively change the colours of the selected objects. Another one that is interesting for me, is "User Interface for SVG Filters". Are these suitable (free) projects which I could submit an application for? Any advice?

My point was not about a technical limitation, but the common practical approach to drawing in perspective: you draw a box and the VPs remain in your imagination only.

I wonder if you can keep proportions and perspective apart at all, if you have no movable camera and no projection from a reference. First image, if I drag the lower front corner, do I change perspective or proportions? -- Thorsten Wilms Thorwil's Creature Illustrations: http://www.printfection.com/thorwil

GSoC Proposal from a Minor :(
by Joel Snyder 24 Mar '07

24 Mar '07

Hey everyone, I'm brand new to the Inkscape development world, however, I have been interested in graphics since a very young age. I was on IRC earlier today asking around for advice on a python script for _Blender_ (Notice, not Inkscape) for a 3D `SVG' editor; more like : 1. An advanced hack for Blender to convert meshes to control points for a collection of Bézier patches. Then use the topology tools to project the NURB surface to a bunch of curves on a plane to save as an SVG file. Of course a few passes would need to be made, one for the outline as Bézier curves, one for textures, gradients, on and on as you wish ;) ! ^ -> .Blend to SVG 2. I haven't seen an SVG yet to this date that hasn't been HAND-coded to include great animation. This could be solved by use of using Blender's amazing animation/tracking/timeline UI as a most needed helper tool. ^-> SVG Animation 3. AIGLX/Beryl is teh man! (Sorry for incorrect grammar..) But it really is, and it attracts a lot of people looking for something pretty...now imagine if _artists_ could be drawn to a system like that... Sadly, however, my dreams of having this amazing UI of new dimensions, rotations, amazing color, and all of that, are still not progressing. As such, that makes me feel bad as a developer. SO, let's start working guys and girls! What we need are analogies for the UI! They allow the user to bootstrap (compiling lingo..) to unfamiliar systems. Simply, I want to help people learn how to use complex things such as boolean operations, multiple gradients, and _artistic/thoughtful_ simplicity while drawing...making a picture with 10E10 control verts is pointless unless you are mapping the [Hemi]spherical view of the Universe! In order to achieve this, we need to see what a picture is _made_ of. We need to see the back, front, top, bottom, middle, second to last!, basically _every_ perspective we can get of layers to help people visualize better what they are trying to make. Art isn't about efficiency or even skill to put something to paper....it's about the creativity that happens, expression of that should come through careful analysis of oneself , and through the education the community should be providing with tools to empower individuals (such as Inkscape). So we must make a `flipbook' or stack of transparent OpenGL canvases, that can be played with like cards in a deck. Or something natural like that...So they could have SVG `cards' we will call them, and you can rotate them in 3D, look at the next card underneath, etc! Now that is a productive use of technology that also makes windows wobbly.... :-/ ^-> SVG/OpenGL Intuitive interface... I have other ideas for graphics if anyone's interested...I dunno not many people _are_ interested in my ideas, haha. ==================================================================== The most Important part... ==================================================================== But basically, after finding that I need to concentrate on coding the Blender part of the code...making all the SVG effects from scratch would take quite a while for a little me! That's where I turn to you people. Somehow I want to connect the Inkscape codebase as well as the Blender sources to a common fork, at least. 2D vectors and 3D aren't that different after all ya know! Why can't we all be friends? ;) ==== P.S. ==== About SoC...I'm most certainly under 18, if you couldn't tell from my unarticulate diction, syntax, grammar, etc. Therefore, _if_ anyone wants to use these projects for it, you are free to do so since I am not eligible.

SoC proposal: ImageMagick effects in Inkscape
by Nicholas Bishop 24 Mar '07

24 Mar '07

Hi, I have written up a proposal to Inkscape for this year's Summer of Code. I'd be much obliged if you guys could give it a look and let me know how it is. Thanks, -Nicholas Bishop == Project Proposal == The goal of this project is to add multiple raster effects to Inkscape through the ImageMagick library. == Details == Integration with ImageMagick will be achieved using Magick++, the C++ binding for ImageMagick. Magick++ comes with excellent documentation, which should greatly ease the integration process. ImageMagick has quite a large set of effects, probably at least 50 or so. Time permitting, all of these can be added to Inkscape (though naturally I'll skip some of the unnecessary ones like flip and rotate.) The initial GUI for the raster effects can be quite simple; most effects take only a few inputs, if they take any at all. In order to avoid dumping 50 new menu items into the Effects menu, I propose creating a single 'Raster Effects' menu item, which will bring up a dialog containing a list of all the effects, and space enough to show controls for any parameters the currently-selected effect might have. A handy feature to implement, time permitting, would be a small preview window showing how the effect will look when applied to the selection. My proposed schedule for this project is based on the timeline suggested in the Inkscape wiki, with some modifications: 0) I've already successfully built and installed the latest revision of Inkscape from SVN. 1) Make the modifications to the Inkscape build system needed to use the Magick++ library. I have some prior experience with autoconf scripts. 2) Start building the basic code that will be used for all the effects; get one effect in ImageMagick to a usable state (I'll start with something like the negate effect since it's easy to see when it's working correctly.) Also begin code documentation. 3) Implement more ImageMagick effects. 4) Finish the code documentation and implement a test suite. Note: I'm not familiar with how Inkscape's existing testing code works, so I will need guidance from my mentor in this area. 5) If I complete the above plan before time runs out, I'm confident that there are more tasks related to the earlier work that I can fill in the remaining time with. For example, it might be useful to implement a stack of raster effects, so instead of simply applying effects to a selection, multiple effects can be attached to it, and arbitrarily reordered and altered at a later time. Doubtless other useful side features will be suggested as the project progresses. == Bio == I'm a computer science student at the University of Maryland, College Park. I don't have any summer classes or jobs, so I'll be free to devote as much time to this project as necessary for me to complete it successfully. I've been excited about the possibilities offered by open source graphics applications since I switched to using GNU/Linux several years ago. I've regularly used GIMP, Inkscape, and Blender for some time now, and in that time I've been amazed to see how far each has come. Three years ago, in an effort to duplicate some of the new tools becoming popular in commercial 3D modelers, I started a graphics project called SharpConstruct (sharp3d.sourceforge.net), an open-source 3D sculpting tool. While working on SharpConstruct I gained experience with C++, the automake system, and gtkmm. This was my big introduction to the world of free software development, and while it was a relatively small project with only one other developer, it was an invaluable experience for me in terms of learning about programming and interacting with the many interesting users of open source graphics software. Last year I successfully completed a Google Summer of Code project with Blender that involved adding three new modeling tools (written in C) to the program. (See Sculpt Modeling, Retopo, and Multires in the 2.43 release notes: http://www.blender.org/development/release-logs/blender-243). Last year's Summer of Code was quite an experience for me; although I was able to complete all the tools I had outlined about in my proposal and more, it was not until some time after the final SoC deadline that my final (and rather large) patch was reviewed and merged into Blender's main CVS branch. In order to complete the merge I was given commit rights, and I continued to further develop and extend the tools. It was not until February of this year that Blender 2.43 was released, which was the first official release to contain the tools I wrote during the Summer of Code. The community response to the tools was overwhelmingly positive, and since then I have continued to maintain and extend the tools. For this year's Summer of Code I am applying to three organizations: BZFlag, GNOME, and Inkscape. I'm looking forward to another great experience of writing code, and as with my project last year, I hope to continue working with Inkscape after the conclusion of the Summer of Code.

Saying hello
by Miklós Erdélyi 24 Mar '07

24 Mar '07

Hi all, I sort of disappeared after last year's SoC was over, but some of you might remember me. I'm a student pursuing an MSc degree in Computer Science from Hungary who contributed to Inkscape with SoC working on the Cairo-based PDF exporter(s). My 'disapperance' was mainly because of an overloaded schedule at the university and because of other activities. I apologize for this. Looking back now I know that developing the native PDF export extension into a full-blown one would've been a better approach because with that now Inkscape wouldn't have to wait for Cairo to get decent PDF export capabilities. Of course, in the long term, the integration with Cairo is a good thing. But I'm glad that the work on Cairo's PDF backend went in the direction I was investigating. Now thanks to Adrian Johnson transparent gradients are supported in Cairo (fortunately he could make good use of my previous patch). Rendering of groups is a bigger issue since that would need a reorganization of how the PDF backend's functions now work (especially the stream handling functions). I wrote proof of concept code for this at the end of last summer but there wasn't enough time to polish it into a full solution because of the involved deeper modifications to the backend. Now, building on the experience I gained last summer, I would be happy to work on PDF import for Inkscape taking part in this year's SoC. My approach would be to use Poppler for parsing the PDF document and then generate Inkscape's representation in memory from an output device. Other solution would be to use Cairo's SVG backend to generate the SVG file from the PDF document using Poppler and import it with sp_document_new_from_mem. Though I doubt that this would yield good quality results. I can't see a mentor mentioned for this project idea in the wiki. So who would be the mentor for this project? The obvious advantage of this project compared to last summer's Cairo PDF export project is that regarding development it wouldn't depend on any external libraries so it could be actually done in three months. Please follow up with your comments regarding the PDF import issue. Best regards, miklos

How debug you under windows?
by Bernd D. 23 Mar '07

23 Mar '07

Hi, Im new here. I have check out inkscape from svn and build its under WinXP like describe on http://wiki.inkscape.org/wiki/index.php/Win32Port. It was very easy. Many thanks for this. Next step I will look into the code with a debugger for lerning how inkscape work and find the right place for my modifications wishes. My question: Are there any way for debug inkscape under WinXP with a IDE integrated debugger (e.g. DevC++, Code::Blocks, Eclipse/CDT or MS Visual C++)? How debug you under windows? Thanks in advance!

"Repeat last action feature", need some advise

23 Mar '07

A feature requested by spikevision is the following: Repeating the last action > No "Repeating" is different than "redoing". It refers to applying the same > action again on an object or on a different one. Redoing reapplies the > action that was undone. Some drawing programs, like CorelDraw, give the > ability to repeat the last action(CTRL-R). For exemple, if you applied a > color on an object, you could select another object and repeat the fill > action. The second object will have the same color. If you performed a > "rote/move/leave original" action on an object, this action can be applied > to the newly created object. This can be handy when creating patterns like > in the european flag exemple of "A Guide to Inkscape" by Tavmjong Bah. > This > would be faster since it could be done with just a few keyboard shortcuts. I began its implementation, but as i'm not sure to do it in the right way, i would like to discuss with someone having a better vision of the source code than mine. I attach you what i've done for the moment, waiting some feedback before to continue. Also, spikevision sent me some icons that he drew for the 'repeat last action' button, and i forward it to you : which one do you like more ? (to me, it's number 6) Cordially, cbvJohn

Johan goes LIVE for GSoC

Hello all, Here is my application, please give me comments so I can improve it. Most of you know me already but I decided to write a biography anyway :) What happened to grids? Yesterday I committed my grid framework implementation which facilitates easier grid implementation. I think the grid GSoC project should focus more on technical 3D drawing then only on grids (see http://sourceforge.net/mailarchive/message.php?msg_id=38507645) I decided to have a go on a topic I had not worked on yet. I am very enthusiastic about the live effects, especially after a reassuring IRC chat :) Unfortunately I was not able to pass this enthusiasm onto a friend who is too psyched up about some other GSoC project where he gets some DSP hardware to work on...

CorelDRAW Import

Random thought. I was thinking about the CorelDRAW import SoC project, and assuming to myself it may be best to stay away, since the potential IP problems *may* be even worse than working on text (which may actually be generic enough to not have to worry). HOWEVER I want you guys to know that I can help put together a bunch of test files, and even test the code of whoever ends up working on it (SoC or not). So don't forget! Gail

Ping (SoC)
by Eric Sumner 21 Mar '07

21 Mar '07

I'm here, like several others, because of Google's SoC. I am a Master's student in Mechanical Engineering at Southern Methodist University. I have kept an eye on Inkscape for several years, but I have only rarely had occasion to use it. I, like everyone else here (it seems), am interested in adding facilities that will make Inkscape easier to use to make 3D drawings. Being an engineer, I am also interested in being able to use it to make orthographic drawings. Aside from the 3D box tool, there are several features that might prove useful for 3D drawing: 1) Isometric/Axiometric grid 2) Diagonal guides (converging to a vanishing point) 3) Drawing with a prespecified transformation 4) Make Ctrl-dragging a node observe the object's transformation matrix 5) Perspective transformation (this would require somehow extending SVG's transformation mechanism) 6) Support for snapping non-node corners of rectangles I would be happy to work on any of these features over the summer. The usefulness of the first two seem obvious (to me), but the rest may take some explaining. Being able to set a transformation before you start drawing would allow you to, for example, set up drawing top faces for an isometric drawing, and have the rectangle tool work properly for those faces. Similarly, it would be useful to have a convenient way to move a node only along the basis vectors of an object's coordinate space, thus moving horizontally and vertically in the conceptual image. In conjunction with the previous two items, a perspective transformation would allow the same manipulations of orthographic images to be applied to perspective images. As for (6), this is usually taken care of by bounding-box snapping, but that doesn't work when the rectangle has undergone a transformation, making its corners not at the corners of its bounding box. Also, for bug #1674596, would an acceptable replacement for "Export Bitmap..." be "Render to File..."? This seems like an ideal bug for me to figure out the patch submission process because the change is only one line (I think; I haven't been able to test it yet). -- Eric Sumner

NUBIE: extending pstricks output; printing subsystem
by Richard Henwood 20 Mar '07

20 Mar '07

Hi folks, I'm looking into fixing (text doesn't appear in output with latest SVN) and extending it to support embedding text as text. During a preliminary familiarisation hack, I've introduced a function: PrintLatex::text(Inkscape::Extension::Print *mod, char const *text, NR::Point p, SPStyle const *const style) (using ps.cpp as an example). I need the position of the text, and I was hoping that p[NR::X] and p[NR::Y] would give this, but they have the value 0.0000 0.0000 I'm new to cpp and Inkscape. Can you advise where I might be going wrong - and any wiki documents I should be checking in addition to PrintingSubsystem best regards, richard

Contributing...
by Jeff Schiller 20 Mar '07

20 Mar '07

I've become interested in Inkscape again and I'd like to figure out a good way to contribute. Here's a couple things I thought I'd throw out there: 1) I'm used to Bugzilla, has there been any discussion about moving away from a Sourceforge Bug Tracker into something a little more powerful (in terms of search? 2) In Mozilla, anyone can submit a patch to a bug, then the admins/super-reviewers must accept and merge the patch. Is there a mechanism for this within Inkscape? For instance, I'd like to report a bug against a SVG tutorial and then post a suggested fix for it that an admin can take and merge into the codebase. Similarly, my ambitions would be to get into the source code of Inkscape eventually and attempt another patch (this is more of a long-term goal though). Basically is there a way for the "casual" developer to submit patches in a standardized way? Thanks, Jeff

Security updates to Inkscape
by Kees Cook 20 Mar '07

20 Mar '07

Just before 0.45.1 was going to release I happened to do an audit of Inkscape's use of printf-style format strings (and the "..." argument). Unfortunately, there were multiple vulnerabilities[1]. Aaron gracefully delayed the final release so I could get CVEs issued, and notify other distributions. The basic problem the use of a *printf call directly on a variable without a format string. For example: printf(variable); vs printf("%s",variable); In the former, printf will parse any format chars in "variable", including the dangerous "%n", which allows for arbitrary memory overwriting. When functions use "..." to take in format strings for later processing by a *printf function, you can end up in the same situation. (Sorry to pick on ishmal's code, but it's a good example.) From the recent security fix commit: - status(event.getData().c_str()); + status("%s", event.getData().c_str()); "status" was defined as: virtual void status(const char *fmt, ...); Now, since the code is *filled* with format string "..." usage, it can be a real pain to find them all. Luckily, gcc has an attribute to flag a function as acting like a printf-family call, and Glib has a macro to create this attribute if gcc is being used as the compiler. So, now "status" is defined as: virtual void status(const char *fmt, ...) G_GNUC_PRINTF(2,3); The two args in G_GNUC_PRINTF point[2] to the format string variable, and the "..." argument. In the case of a class (as above) there is an implicit "this" argument as argument #1, meaning the format string "fmt" is really arg 2, and the "..." happens at position 3, as reflected in the G_GNUC_PRINTF usage. These markings, combined with the gcc compiler flag "-Wformat-security" will issue warnings about missing format strings, and do other strict type-checking. I've added this to the default CFLAGS as well. (And -D_FORTIFY_SOURCE=2, which adds even more protections via glibc.) Overall, many format issues were corrected[3], only a few of which were security-sensitive (37 files changed, 120 insertions(+), 111 deletions(-)). When making new "..."-using function, please review the glib macros for appropriate attributes, and take care to use them safely. I'd especially appreciate it if someone could look at: ./display/sp-canvas.h:SPCanvasItem *sp_canvas_item_new(SPCanvasGroup *parent, GtkType type, const gchar *first_arg_name, ...); This seems to be a NULL-terminated list (and not a format string, obviously), but it should get marked as such[4] if that's true. The dom/js/ tree is stuffed with "..." and I did not audit it, since it is not hooked up yet. However, we need to be very careful with it, and I'd MUCH prefer this code stayed outside of the inkscape code base so we can just link to an external library in the event of security updates to those libraries. Let me know if anyone has any questions; I'd like to keep inkscape as safe as possible. :) Thanks, -Kees [1] Try it yourself: prior to current trunk and 0.45.1, run this: inkscape /tmp/no-such-file-%x.svg And you'll see the "%x" turned into a number off the edge of the stack. The Jabber protocol handler was also vulnerable.

I arrive just now in this mailing list. At first, I have to say that my mother language isn't english, but portuguese, so I ask you to apologize any grammar/spell error. Here, in Brazil, I'm very interested in Inkscape plugins development, although I'm still trying write the first and studying things like SVG and XML. You also can find me in Inkscape-Brasil mailing list. It's a pleasure to be here. [ ]'s -- +..........................................................+ . Gmail:celina.jorge@...400... . .

Re: [Inkscape-devel] Summer of Code 2007 - Possible application?
by Gail Banaszkiewicz 20 Mar '07

Hey Max! You seem to share the same enthusiasm as I do. You have beat me to the bug fixing though... I was hoping to do that this week along with putting together some proposals ;) > On second thought, the shared interest of two people could also be a > great advantage because maybe there is a way to split the project into > smaller parts which can be tackled more or less independently. I think that if this is possible, it's a really great idea. Our abilities seem to match up well, because as you say, you have a (probably) deeper understanding of the math, and I (may) have more programming experience given that my major is computer science rather than minor. Yet I imagine we are both sufficiently proficient in both aspects. I guess we can wait and see what the good mentoring folks say, but if we can come up with complementary proposals where we each have separate and sufficient work, I imagine our chances are good! I should note, though, that there are many suggested projects I am interested in, which somewhat deters me from wanting to come up with my own ideas ;) Instead, I may just try to put together a killer proposal for the suggested project ideas. We'll see what happens. My point here is mostly that if you turn out to be more suited for the 3D tool, there are no hard feelings. We should both put forward multiple proposals if possible and it would be nice if we could both get in. Looking forward to seeing how this will play out, Gail

Inkscape and barcodes - Inkbar (fwd)
by Alan Horkan 19 Mar '07

19 Mar '07

I was going to send this to inkscape users to help inform them about the Inkbar Barcode extension and ask if anyone know who was the author of Inkbar. Instead I thought maybe it would be better to direct it here so that developers might share their thoughts on making extensions easier to develop since Inkbar does suffer some of the common problems? ---------- Forwarded message ---------- Date: Mon, 19 Mar 2007 22:50:05 +0000 (GMT) From: Alan Horkan <horkana@...44...> Subject: Inkscape and barcodes - Inkbar I was thinking a barcode program could make some of the work I'm doing at the moment a lot easier, especially one I could also run on windows (Kbarcode is a good barcode AND label program but it is not availalbe for windows). On a whim I searched google for Inkscape + Barcodes and turned up a nice page in the Wiki listing some extensions* which are not included by default (doesn't make sense to include all extensions* by default). http://inkscape.org/wiki/index.php/ExtensionsRepository In particular it looks like "InkBar" might do what I need http://www.inkbar.lineaire.net/ My french is a bit rusty and I cannot see any contact or author information either on that page or included with the extension but I would apprecaite some help and perhaps my concerns with this script* are applicatable to others. I've had similar concerns before when writing scripts for the GNU Image Manipulation Program (GIMP) and some Javascript bookmarklets so these suggestions are based on a fair measure of experience, and some of things I wished I'd had to help me write my scripts. First there is the problem of translation. I'm not sure how we can help translate third party extensions/plugins/scripts/whatever*. I would guess that perhaps certain strings would keep coming up over and over again such as Angles, Detail, Gradient, Path, or something like that so maybe Inkscape could provide some kind of stock labels which would get translated once then any script writer could reuse them (something like how Gnome stock lables are supposed to work)? The other problem - and I've seen this a million times with GIMP scripts - is input checking. The inkbar script fails if the required 12 or 13 characters are not provided, which isn't very forgiving. (In the case of inkbar the rest could probably be padded with spaces.) In general scripts will require input checking, and hopefully this isn't something each script developer would need to writer their own collection of checks and tests for (because in that case testing is unlikely to happen at all). In the case of Python scripts (and any other scripts) there is something of a delay between the time the user sets the values and then hits OK (lets call that stage 1) to execute the script and then another delay before the script runs (stage 2). In practice this delay is usually quite short but delay and errors could be avoided if there was some immediate error checking as the user types to make sure a letter is not typed into a box where only numbers are allowed even before the OK button is hit (stage 1). After the OK button has been hit other checks may also be necessary. (Sorry very tired, I'll stop and try and explain better later, but I think I should probably have phrased things for developers in terms of preprocessing and postprocessing like on Web based forms as an example of how much easier extensions might be.) Anyway, I could do with some help contacting the author of the Inkbar barcode extensions and I hope to get a lot of use out of it (and help make it easier to use, provide an English translation, and anything else i can think of). I do believe it could gain inkscape a lot of attention in small businesses and more. (Useful as Inkbar could be for me I'm not saying I'd want to include it by default, not yet anyway. Inkscape for artists.) Off to see if I can modify the script to group the output to keep things tidy and stop them from falling apart. Sincerely Alan Horkan http://advogato.org/person/AlanHorkan/ http://www.linkedin.com/in/alanhorkan http://alanhorkan.livejournal.com/ * cannot use the jargon consistently, brain hurts, long day P.S. Looking at the command line options I see they are also in French, hmm.

Help about Animate Document in Inkscape
by Federico 19 Mar '07

19 Mar '07

Hello Bryce and M-List member, you remembar that I'm an Italian student and I'm writing my Thesis of bachelor in engineering on the diagrams animated in inkscape. I explain you my problem: I would have the necessity to modify the attributes of field STYLE of an object to regular intervals of time. More in the detail, I would have necessity to write a “extension” of Inkscape that reads the data of an object (rect, path, star, etc.) from a DBMS and he applies them to the present object on the screen. As I said to you in one mail of some day makes (the bringing back under): --------------------------------- On Tue, Mar 13, 2007 at 12:08:15PM +0100, Federico wrote: > Hello, remembered of me! > I'm a student graduating in Computer science Engineering and I'm leading a > thesis on the Vectorial Diagrams Animated in Inkscape. > > I had successful to insert of inkscape a "parallel" Thread to the main > program, that it reads of the regarding data the characteristics of an > object and then assigns them to the object by means of the endured function > > sp_repr_set_attr(nodes[i],style.c_str(),attrib.c_str()); > > nodes[i] -> it is a carrier of gunlayers "Node" > (std::vector<Inkscape::XML::Node *> nodes;) > style & attrib -> are strings. > > But after this call, the program crasha and it is closed without some > message.

When you are in the debugger, issue the command 'bt'; this should give you a backtrace to show the functions that were being called to reach this crash. You will probably also need to specify which thread you're debugging; since Inkscape is single threaded we don't have directions on this, however they can be found on the internet - Ubuntu has good directions for debugging multithreaded applications. A technique that I find useful to help identify bugs like this is to set a break point in the code somewhere prior to the segmentation fault, and then step through the lines until the segmentation fault, and look at the values of some variables that might be causing the problem. Generally segmentation faults are caused by mis-used pointers. For instance, trying to use a pointer with a NULL or undefined value. Regarding adding multi-threaded capabilities to Inkscape, this is something which we have avoided. In part, it makes debugging more complex, and it opens a large class of bugs that are challenging to deal with. We've also heard that some of the libraries we use may not behave as well when used in a multithreaded app. If it is very important for you to have the multithreaded capabilities, please explain why; otherwise you may wish to go single threaded to save yourself a lot of difficult work. Either way though, it's exciting to hear of your work on animated diagrams in Inkscape! I'd love to hear more about it. Bryce --------------------------------- I have used a Thread parallel that goes to write field STYLE of the rappresentazione of an object. But in this way a Segmentation Fault is generated. How I can avoid this problem? For me it is not binding that my extension is multithread, only interests to me that to regular intervali of time they can be applied of the changes to of the present objects on the canvas and that they have a particular ID or one particular LABEL. You can give me of the straight ones in order to resolve the problem?

Summer of Code 2007 - Possible application?
by Maximilian Albert 19 Mar '07

19 Mar '07

Hi everyone at the Inkscape team, my name is Maximilian Albert and I am currently a student of mathematics with minor subject computer science at the university of Heidelberg, Germany. This email serves the purpose of introducing myself to the Inkscape community because I am considering applying for Google Summer of Code 2007. For your convenience I have split this email into several sections. I apologize in advance for its length, but I figured it might be helpful to be a bit more verbose and give you a chance to get an impression of me (at least, as far as this is possible via such a rather impersonal medium as email). 1) Current stage of my education. Right now I am in the final stage of my Diplom thesis in mathematics (the Diplom is roughly equivalent to a combined bachelor and master degree). I expect to complete my thesis in the next few weeks. Subsequently, there are four oral examinations the last of which will probably take place in late autumn or even further towards the end of the year. Passing these will finish my studies. 2) How I got interested in the project. I learned about Google summer of Code only about one week ago when I accidentally stumbled across the corresponding webpages. I was fascinated by the concept right from the outset, but with regard to the current state of my studies quickly jettisoned the idea of applying. I figured it would be illusionary to try and tackle an additional project of this extent, given that I will probably be spending most of the time in summer learning for my exams. However, the idea kept lurking in the back of my mind, and since I found myself more and more excited about the project's concept, I thought it over and came to the conclusion that there actually is a very good - and, most importantly, realistic - chance to successfully work on it. By now I am very much willing to give it a try. The point is that I can probably choose the dates of my exams in such a way as to keep the period during which SoC is supposed to take place completely free from any other duties. At this point you will probably be thinking that I am much too over-enthusiastic and therefore running the risk of completely misjudging my capacities. Please be assured that I definitely won't submit an application unless I can 100% guarantee that I will be able to commit my full time and power to the project. I am well aware that this requires very careful planning and organization. But I proved more than once in the past that precisely this kind of "double burden" makes me tap my full potential (this is also why I am mentioning it at all instead of keeping you in the dark about it). I am sure that in case I should really come to the conclusion that an application is realistic, and should I be chosen, I would be of great benefit for the project. 3) Why Inkscape? Having decided to wholeheartedly think about getting involved, I browsed the list of mentoring organizations and was delighted to find Inkscape among them. Way back in the last millenium ;) when I was still working under MS Windows I had made my first experiences with Adobe Illustrator and got even more fascinated about computer graphics and visualization than I already was. After my switch to GNU/Linux many years ago I discovered Inkscape and since then have used it working on a handful of projects, most of which were fun ones only of interest to myself. But some examples are actually used as the logos on my choir's website. See the main page at http://www.kammerchor-alumni.de as well as the several subcategories (unfortunately the site is in German, but clicking on the icons shouldn't require any advanced language knowledge ;)). Recently I have been following the improvements and breathtaking new developments announced on the Inkscape website. More than once I thought about making a contribution (in fact, I already made a tiny one in the form of reporting bug #1598337, but I guess that doesn't really count). Lacking a concrete starting point, however, and above all the necessary time during the preparation of my thesis, I had to postpone the idea. Therefore I was excited to learn about the opportunity of getting involved in the framework of GSoC. 4) My experience in (graphics) programming and open source development To tell the truth, in Heidelberg the demands for computer science as a minor subject with regard to concrete programming tasks are not the highest. Therefore most of the programming I have done so far were smaller projects for my own amusement. However, when working on a practical at the visualization group of the Interdisciplinary Center of Scientific Research [1] which was required for my Vordiplom (a kind of pre-degree), I was lucky in that I could bring in an idea of my own which developed into a very fruitful and quite extensive project. It was concerned with the development of a program I dubbed HyperView, which serves as a tool for 3-dimensional visualization of 4-dimensional spheres, using the Hopf fibration. The projects' documentation can be found at http://pille.iwr.uni-heidelberg.de/~kugeln/ (Luckily, I prepared it in English at the time.) Be warned, however, that the code has not been maintained since the completion of the project in 2003, and I am not even certain that it will currently compile. In recent times my extensive hobby of making music (singing in particular) and in this connection preparing score arrangements and even composing short pieces has led me to get involved with Lilypond,[2] a free(TM) musical typesetter and automated engraving software. My first small contributions were the creation of a new notehead (requested by a composer on the mailing list), a small bugfix and one or two bug reports. Right now I am working on a couple of small to medium-sized projects ranging from the creation of further noteheads and other symbols to the implementation of a new style for microtonal accidentals (used, for example, in contemporary pieces as well as Eastern European and Asian music). All of these are close to being finished, and I hope them to be included in one of the next few development releases (as soon as I will have submitted them). As far as my general programming knowledge is concerned, I am proficient in C, C++, HTML, (shell) scripting, and even such an excentric thing as metafont. ;) Furthermore, I am knowledgeable to different extents in a couple of other languages/tools, including Scheme/Lisp, Python, Perl, sed, and awk. 5) Ideas for a SoC project The most severe problem I am facing right now is that in the short period since mid-week (when I discovered SoC) I haven't yet been able to develop really great ideas about possible projects I could tackle. My primary intention so far has been to get acquainted with the source code (see also point 6 below) and to find out for myself if it would make sense to submit an application (which the way I see it now I would almost certainly answer in the affirmative). Of course, I browsed your website where first and foremost the description of the planned 3D box tool captured my fascination. I believe that all of the ideas related to it that are mentioned on the webpage are certainly both tractable (although the whole lot is doubtlessly too much for a single person during a SoC project) and promising to be fun projects. The underlying mathematics are definitely comparatively trivial from a mathematician's point of view, but judging from my experience with HyperView (see point 4 above) - albeit only on a gut level, without having thought about details yet - I suppose that a lot of small problems can be avoided by choosing the right design approach. I think that my knowledge of the underlying algebra would definitely prove very useful in this regard. Unfortunately (for me, at least ;)), I saw that Gail Banszkiewicz has already exchanged her ideas with you about this project (I may have missed other peoples' contributions on the subject since I only skimmed over the mailing list archives). I certainly do not want to come into conflict with her, especially since she has contacted you much earlier and seems to have more precise ideas. So I will have a deeper look at the other projects described on your website and will also try to come up with and crystalize out my own ideas. On second thought, the shared interest of two people could also be a great advantage because maybe there is a way to split the project into smaller parts which can be tackled more or less independently. If it were possible to agree in some way on a certain design or common interface prior to the start of the project, the two of us (or even more students if interested and accepted) could work independently on their specified task(s). In the end the various features could be combined to yield a much more powerful tool than would have been possible if worked on by a single person alone. Does any one of the mentors who is more into it than I currently am see a possibility for this? Of course, this is only a vague idea and would certainly require Gail's and other people's approval. And I would like to reemphasize that I definitely don't want to thwart anyone. Just thinking aloud ... 6) Completed tasks and open issues related to an application Following the recommendations on your website, I have tried to get acquainted with Inkscape's source code and internals. This also served the purpose of deciding for myself if it would make sense to apply. IMHO, the results have been encouraging. ;) Yesterday I checked out the svn version and compiled it on my system, which worked more or less smoothly. After agreeing on very short notice to participate in a singing project last night, ;) I have been concerned today with fixing bug #1671665 (randomly chosen from the list). This afternoon I was already about to write that my progress looks promising. Waiting until tonight turned out to be a good decision, however, because in the meantime I was able to actually fix the bug. The fix is submitted as patch #1683338. Please feel free to have a look at it and make comments if you wish. This completes half of the required bugfix task, I believe. It is unlikely that I can work on a second one tomorrow but I will do it in the next couple of days and keep you posted on my progress. As I said, it will also take me a few more days before I can finally decide if working on a project this summer really makes sense. Definitely the last thing I want to do is waste both my and your time with a healf-hearted application that is doomed to failure due to misjudgement and bad planning. I will get in touch with you again as soon as there are any news, such as ideas for possible projects. In the meantime, if there are any questions or proposaly from your part, please do not hesitate to contact me. I am very much looking forward to hearing your comments, thoughts and oponions. Until then thank you very much for struggling through this extremely long email! Best regards, Max

Latest news on LGM 2007 Montreal
by Louis Desjardins 16 Mar '07

16 Mar '07

Dear Inkscape team! I'd like to post a few info here for the benefits of all travellers to LGM. 1. I know the website of LGM is outdated. I expect things to be straightened up in the coming days. :) 2. Meanwhile, the Create wiki has been updated : http://create.freedesktop.org/wiki/index.php/Conference 3. Visa. Please review the VISA info as it might apply to some of you when travelling to Canada. 4. Rooms. We have dealt a LGM special price on rooms at the Student Residences of the uni hosting the LGM. All info is on the wiki. What has guided me is to allow LGM participants and especially the devel teams to be together most of the time (remember we only have 3 days), have internet access and enough room to organize meetings. All that into a calm environment. The residences are on the site of the LGM at less than 5 minutes from the main auditorium. Arrival date : May 3 (Conference starts on May 4). We may be able to arrange things if you want to arrive earlier. Please let me know. And we also want to avoid getting people lost in the city (Montreal is a North American city, quite extended...) and taking up most of their time getting from their hotel to the LGM site and back. I have made a reservation on 50 Single rooms + 5 Cosy Suites (with large bed) and there are lots more room there if needed. On each other floor of the residence people have access to a Salon that can hold a good 10 to 12 people meeting and we also have access to another 3 large rooms for meetings with more than 20 persons at a time. 5. Sponsorship. I am deeply concerned by sponsorship. We have to be able to help people get to the LGM. So far, I am still waiting on confirmation but sponsors have shown clear interest in helping us again this year. It's a matter of time until we know for sure the exact amount we going to get from the sponsors. Please stay tuned. I will post the info as soon as I have something to say. 6. LGM speakers. I would appreciate that people interested in making a talk at LGM show up on the Create wiki. Some people have contacted me early by e-mail. Please fill the wiki as well. This is the only sure way to help me put the schedule together. Also, if you know someone that would be a good speaker, don't hesitate to propose his/her name. And don't forget the subject suggestions as well. 7. LGM Brochure (see wiki for details) : we'd like to have each project described. Cédric Gemy should be able to take care of Inkscape's description and maybe more. At the same time, if anyone on this list has images created with Inkscape that we could use to show what the program can do, please contact me off list. We don't need that many images but since we're distributed in the graphic designers magazine, the higher the level the better the effect, imo. 8. If anyone has a question or comment or suggestion, please don't hesitate to get back to me. Hope to see you again at LGM2 and of course meet new people!

0.45.1: Small translation changes
by Colin Marquardt 16 Mar '07

16 Mar '07

Hi, it seems that translations in the 0.45.1 branch got some new (< 10) fuzzy strings. Also, the very first msgid which is meant for metadata has a strange header: #: ../src/widgets/toolbox.cpp:4037 ../src/widgets/toolbox.cpp:4058 #: ../src/widgets/toolbox.cpp:4087 ../src/widgets/toolbox.cpp:4108 #: ../src/widgets/toolbox.cpp:4135 msgid "" msgstr "" "Project-Id-Version: inkscape\n" [...] All these toolbox.cpp lines should not be there. They don't seem to hurt though. If someone has time to dig into this and possibly revert a commit, please do, I myself probably won't find the time before the 0.45.1 release. Cheers Colin

OpenICC in SoC
by Jon A. Cruz 16 Mar '07

16 Mar '07

OpenICC has also been selected for Google's Summer of Code. There's a blog entry on it at http://www.valdyas.org/fading/index.cgi/software/iccsoc.html And their main page on it at http://freedesktop.org/wiki/OpenIccForGoogleSoC2007 I point this out in case there are some students out there who aren't as interested in SVG and Inkscape directly, but who are interested in various color issues. We should be interested in OpenICC as the work there is good for graphics apps and professionals, and Inkscape will gain more integration of it over time.

Font size: Pixels vs. Points
by Jed Frechette 16 Mar '07

16 Mar '07

I've written a simplistic Python script [1] that will change all of the font-size units in an SVG file from pixels to points. The script doesn't actually do a conversion it simply replaces the unit suffix of px with pt. If you create some text in Inkscape with size 10 and save it; font-size:10px Run the script on the file; font-size:10pt Open and edit the file in Inkscape; font-size:12.5px This is a workaround for the bug that the UI never shows the units (pixels) associated with font size numbers and it is difficult to specify sizes in units other than pixels [2]. This is the quickest hack I could put together when I realized that the text in all of the figures for my thesis was the wrong size, therefore it hasn't been tested much, so if anybody uses it you should take appropriate precautions (e.g. backup your data). Clearly this is an ugly hack, but if there is no interest in fixing the underlying issue, or it's to painful, I could put together something similar as an effect. It seems like a better solution would be to, at a minimum show, what unit font size is in. When setting the default font size in the toolbar specifying a unit results in the correct conversion, so maybe a more general fix wouldn't be to hard. Unfortunately, trying to specify a unit when changing the size of existing text or doing anything with a unit in the text dialog doesn't work. In any case, I would be interested in getting some input from others. Best, [1] http://www.unm.edu/~jdfrech/svg_font-size_px2pt.py [2] See bugs 161347, 1619753, and 1657337 P.S. Sorry about the cross-posting but this seems like a somewhat nonobvious issue that has tripped up at least a few other people before me. -- Jed Frechette http://jdfrechette.alturl.com 3203 Dead, 23,417 Wounded

New transform idea: Quick XForm
by Mazin 14 Mar '07

14 Mar '07

I've been working an a drawing that involves a lot of little objects that have to be placed in the right spots, and I've found that it's cumbersome using the regular transform tools. I have a new idea (please tell me if it's been done before) for a tool that will make this much easier. Basic synopsis: a tool that transforms an object based on a single mouse drag, combining moving, rotating, and scaling into one. This makes transforming an object much quicker and more natural. It's even more useful when creating multiple randomish clones but with finer control. Please, see the full explanation at http://files.aztekera.com/images/Quick%20XForm.svg Inkscape recommended. Tell me what you think, Mazin (This has also been posted to Inkscape's tracker on SF.net)

0.45.1 splash screen
by Aaron Spike 13 Mar '07

13 Mar '07

0.45.1 is approaching at an alarming rate! (no, really, it is.) I'd like to collect opinions on the following patch in our tracker. It is more than simply recasting the 0.45 about in blue. There are quite a few differences. If you have an opportunity please make a side by side comparison, and report your opinions. The ultimate question is, of course, shall we replace the about screen with this version for 0.45.1. http://sourceforge.net/tracker/index.php?func=detail&aid=1671402&group_id=9… Aaron Spike

Need some input on bug #1540195 (snapping problem)
by Diederik en Rezi 13 Mar '07

13 Mar '07

While looking into bug #1540195 I ran into some dilemma. This bug occurs when a bounding box is squeezed in between two vertical guides and makes it hard to pull the box out of its squeeze. For more details have a look at http://sourceforge.net/tracker/index.php?func=detail&aid=1540195&group_id=9… The original post includes a nice sample file. This is what's going on: 1) Both the 4 points AND the boundingbox (also 4 points) are snapping, as requested in File -> Document Properties. 2) The origin is set to be at the boundingbox edge, as requested in File -> Inkscape preferences -> Tools -> Selector This will not work in the situation described by bwalle. When snapping the boundingbox, the origin must be at the boundingbox. When snapping the nodes, the origin must be at the farthest opposite node. This is what's going wrong: when dragging the edge at the right, both the bounding box and two additional points will be trying to snap to the left guide, even when dragging the right edge far to the right. The left side of the boundingbox is not being transformed, as it's exactly at the origin. The two additional points though are slightly off the origin, and will be transforming almost invisibly. These are causing the troubles. It's difficult to describe exactly what's going on, the best thing to do is to just try it. This is what we could do: 1) calculate the origin ourselves, instead of obeying the preferences. Should this option even be removed from the preferences? Why is this option available to the user at all? 2) filter the snap points in the snapmanager, to only snap the points or boundingbox edges that are being moved. Points close to the origin could simply be discarded. 3) When dragging the boundingbox, we could feed the snapmanager only the points at the edge being dragged. But this doesn't handle the snapping of a complex object consisting of many points 4) ? Does anyone have any suggestions or pointers? Regards, Diederik van Lierop

website
by Alexandre Prokoudine 13 Mar '07

13 Mar '07

Hi, While working on translation of inkscape.org into RU, I noticed several things I'd be pleased to have feedback on. 1. Documentation page. 1.1. It has a "Translations" section which is not quite related to docs. Should we introduce a separate "Translations" or "i18n" page with information on status of supported languages and basic info for new translators? 1.2. Publications (Overviews). Those brochures are nice, but _very_outdated (0.39). Could we "hire" some artist to give them a new life? 1.3. Example SVG Files. This is not related to docs as well. Maybe we should introduce a basic PR page for SVG? 2. Showcase page. Very outdated. Latest entry dates back to 2005. Don't we have something newer to show people? ;-) 3. Status page. Latest Project Status: 15, November 2005. That speaks for itself. Any comments? Alexandre

NEW: flood fill
by John Bintz 11 Mar '07

11 Mar '07

Inkscape now has a very rudimentary flood fill tool. It works by performing a bitmap-based flood fill on a rendered version of the visible canvas, then tracing the resulting fill using potrace and placing the traced path on the canvas. You can access it by the paint bucket icon in the toolbar. It places the rendered path onto the current layer, so you can have a layer on top (in my case, "Inks") and select the layer below ("Colors") and do the fills so that they always appear below the inks. This tool is in a very basic state, and there are issues with rendering accuracy and memory usage. Some improvements that I can see being done are: * If the [Ctrl] key is held down, clicking on an object changes the fill color to the current fill color, and [Shift]-[Ctrl] changes the stroke color to the current stroke color * A way to either manually or dynamically increase the resolution of the rendered version so that the accuracy of the flood fill is better Try it and let me know what you think. Thanks, John

Selector's scale handle modifiers
by bulia byak 08 Mar '07

08 Mar '07

Currently, when you scale an object by its scale handles in Selector, you can use the following modifiers: Ctrl+mouse drag scale preserving aspect ratio Shift+mouse drag symmetric transformation (around center) Alt+mouse drag slow movement The "slow movement" mode with Alt simply scales the object by 1/10 of your mouse movement, the goal being increased precision. This mode is inherited unchanged all the way from Sodipodi. In my opinion, however, it is weird, counterintuitive and not at all useful. It also has no analogs in other tools. So my question is, will anyone complain if I remove the "slow movement" mode? On the other hand, one useful thing that's missing is the ability to scale the object to 2, 3, 4 and 1/2, 1/3, 1/4 etc of its current size. (This is possible from keyboard by Ctrl+> and Ctrl+< but not by mouse). So I'm thinking about enabling the Alt modifier to do this "quantized scaling". Among other things, this would enable the often needed transformation: flipping an object around one of its bbox edges (by Ctrl+Alt+dragging a side handle). Thoughts? -- bulia byak Inkscape.

Summer of Code
by Gail Banaszkiewicz 06 Mar '07

06 Mar '07

Hi all! I was chatting with Bulia Byak (I believe - please correct me if I'm wrong) on your IRC channel yesterday about Google's Summer of Code. I just wanted to introduce myself to everyone and say that Inkscape is definitely a project I'm really excited about having the chance to work on. More on that in a bit. In the near future, I hope to write the list again with some ideas on possible projects for SoC. So, a bit about me. My name is Gail and I'm a student at Carleton University. This is my last semester of computer science, after which I will be pursuing a masters of computer science in September. My area of interest is computer vision / graphics / computational geometry. This originally stemmed from the fact that, growing up, I have been really into graphic design in a hobby kind of way. My favorite software has been CorelDRAW, and I even got to work at Corel for some of my co-op terms. I worked on the text engine for DRAW X3, so I imagine it will be a good idea to propose projects outside that area to avoid that nasty IP issue ;) The software is quite large, so there are many areas that I never even touched upon. And so you can see why Inkscape is an exciting project for me. I haven't used it much in the past, but was able to recently pick it up quickly thanks to my experience with vector graphics. It looks like the software has an awesome base already, and lots of potential for new and innovative tools. I like your culture of enforcing high usability that was implied during my IRC chat. To me this is a very important aspect that is often given too little weight. That's it for now... If anyone wants to know more about me, please feel free to ask, and if anyone has any big requests for projects this year, I don't mind working with that! And like I said, I intend to play around some more with the program and come up with some new ideas as well. Until then, Gail

It's probably better to reply > here than on comments Shouldn't there be a specification, list of features first? What should be possible with the animation system? I would like to see: - Tracks per object. Layers could be handled as track-folders, then. - The tracks would control an object's 'lifespan' with regions, where a region is basically just a rectangle across time. Outside of regions, the object would not 'exist'. This saves one from tricks like moving objects out of viewport or toggling there visibility in some obscure way. - Keying of shap, stroke, fill, opacity, blur ... - Control over transitions between keys (stepped, linear, progressive ...) Extra: - animation curves (called IPO curves in Blender). Bezier curves (splines would do, too) to control single parameters over time, for example the amout of red in a fill. And just now I remeber it's all SVG and I have no clue what can be put in there in a sensible way. -- Thorsten Wilms Thorwil's Creature Illustrations: http://www.printfection.com/thorwil

If someone else wants to take a look, my guess is that it's "simply" a matter of getting the boundingboxes right. Basically what I did earlier was adjust the visible area (or something like that, I'd have to check) of the export area to the entire image. Usually this doesn't mean that the entire image is drawn for each stripe, but especially if you have objects spanning the entire image this probably could (I couldn't figure out exactly how this all worked, when I tried actually modifying the clipping code I got some results I didn't expect). What it should do instead is just extend the current stripe by the amount needed by any blurs in the current stripe. One theory I had about why modifying the clipping code didn't work (for me) and why the current set up does work was that perhaps some calculations where creating bboxes with negative coordinates and that possibly something didn't like that much, since I suddenly got off set images and so on, but it's mostly guesswork. BTW, if someone gets this fixed there is a good chance it would also fix bug 1643892.

Dev-Builds on modevia.com
by unknown＠example.com 05 Mar '07

05 Mar '07

About the svn-head builds posted on inkscape.modevia.com: are these done automatically or is building manually initiated? (just out of curiosity) More seriously: the quoted time of the build is that PST, CET or...? :) (it can be important when people want to test after bugfixes) As for debugging: the website says to run "gdb --symbols=inkscape.dbg inkscape", however this does not work for me. I use "gdb" and then in gdb I must enter: "file inkscape.exe inkscape.dbg" (note that the order in which the filenames are typed is essential). Then one must enter "run" to run the prog, etc. (I think it is most clear to explicitly write to enter "run" on the website). And... while I am busy: http://inkscape.modevia.com/win32_inkscape_org/win32buildnotes.html needs to be updated for the current buildtool. This helps new developers tremendously. Thanks for your efforts! Johan

Work toward scripting
by Bob Jamison 05 Mar '07

05 Mar '07

Several people have asked me to let them know if there is anything they can do to help out toward DOM scripting. I came across something today that would be of excellent help. It is quite possible that ActionScript might turn out to be a much better fit than Spidermonkey as our JS engine, since it is C++ and we would be able to use C++ inheritance rather than Spidermonkey's C bindings, which are hard to understand, convoluted, and incredibly verbose. We would need to test this out first, however, to make sure that it is feasible and worth the effort. What we would need is a MinGW build of ActionScript. The free Mozilla version of this is called Tamarin, and is available at: http://www.mozilla.org/projects/tamarin/ The code can be checked out via cvs: cvs -d :pserver:anonymous@...1680...:/cvsroot co mozilla/js/tamarin The problems I found are mostly these: 1. there are a lot of _asm{} chunks distributed through the code, and when they include a chunk with #ifdef WIN32, they assume that you are using MSVC. What they really need is to split their #ifdefs for win32 to _MSC_VER and __MINGW32__. MinGW needs to use the same asm code as the linux-ia32 pieces. 2. setjmp in mingw is defined as a macro, so when they wrap that in a macro later, there is a problem 3. GrowableBuffer has some Intel asm in one place, but -no- gcc asm version. Someone needs to write the 10 lines gcc-style. There are others. If the hacks are clean, we could help out the Mozilla guys by sending them a patch. They could use this for Linux, too. So if people are really serious about helping out with scripting, this is a good place to start. Thanks. bob

0.45.1?
by bulia byak 04 Mar '07

04 Mar '07

I think it's time to start working on 0.45.1 - there are lots of patches in the queue. However the most frequently reported problem is still not fixed: it does not work on OSX 10.3.9. Is there anyone on Mac who could look into this and report if this is fixable at all? -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Re: [Inkscape-devel] [Inkscape-user] PostScript fonts print as Courier when Inkscape exports to EPS
by Adib Taraben 04 Mar '07

04 Mar '07

Niall, I am not the Latex expert. I am using Ubuntu and/or Sarge do. Could you provide me some small document inserting the eps and the command how to start Latex I will investigate in this. btw. You probably know PostScript does not support Unicode thats why Inkscape creates own "Subfonts" for each font before using in the document. This is the reason for the "-ISOLatin1" in the font name. The second PostScript issue is that it does not handle font names containing spaces. There have to be brackets around. There will be no easy patch in the next future and you will be save if you convert fonts to strokes before. I will have an eye on that. HTH, Adib.

PostScript printing problem
by James Richard Tyrer 04 Mar '07

04 Mar '07

The short story is that this would print correctly except as a bitmap: http://home.earthlink.net/~tyrerj/files/OG/ogp_open_window_logo_0.svgz This appears to be an inherent problem with PostScript, but I'm not certain about this. If so, it would be necessary to first transform the SVG file into one that could be converted to PostScript vector format. I also tried the blur filter and had the same problem, it won't convert to PostScript vector format. -- JRT

File dialog changes
by Jon A. Cruz 04 Mar '07

04 Mar '07

I just committed the first of a few changes to the file dialogs. Round one here gets rid of the "Append filename extension automatically" checkbox and instead updates the extension live in the dialog. Give it a spin and see how it works. A few more will come in later.

cairo-1.3.14 build for win32
by Bob Jamison 04 Mar '07

04 Mar '07

People interested in Bulia's work on using Cairo for Outline Mode rendering might want to experiment with cairo-1.3.14's faster rendering. I made a win32 build of it here: http://inkscape.modevia.com/win32libs/cairo-1.3.14-mingw.7z To test it, all you need to do is copy the DLL in /bin into your Inkscape directory. bob

NEW: cairo rendering in outline mode
by bulia byak 04 Mar '07

04 Mar '07

I was curious if cairo is in fact slower or faster than our current renderer. I didn't feel like converting us totally to cairo yet, but we have outline mode which is much simpler and perfect for tests like this. So in about 3 hours (of which 2 hours were spent figuring out a known bug in cairo) I converted our outline mode rendering to cairo. The result of this experiment, after I adjusted the tolerance of cairo to match our outline mode quality, is near parity. That is, cairo is about as fast as our own renderer, at least for outline mode (i.e. lots of paths but no gradients or transparency). However this claim needs to be qualified: - It is only true for the latest version of cairo (tested with 1.3.14). Versions 1.2.x are noticeably slower. - This uses image backend to render to a memory buffer, and therefore cannot use any hardware acceleration. Using hardware-accelerated backends will require much more drastic changes in Inkscape's architecture. - Even with image backend, currently cairo is used _only_ for path rendering, each path going to its own temp buffer, and these buffers are later composed together just as they were before. I suspect that if this is optimized by allowing a single cairo context draw all of the paths in the drawing into a single buffer, performance will improve noticeably. In any case, since this does not make for any speed regression, and since it fixes at least one bug that our native renderer had in outline mode, I committed this. Please test outline mode thoroughly and report if you find any problems. If everything works fine I'll remove the old outline mode code and will look into doing some further optimizations. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Buildtool fix
by Bob Jamison 03 Mar '07

03 Mar '07

Running buildtool today, there was an occasion where gcc stopped with an error, but there were only warnings on the output. Turns out that the code handling the piping of the messages from the shell was buggy. No wonder that people wanted a listing file. I don't have that file yet (soon), but the warnings and messages are -much- better now. Also, the latest MinGW mingw-runtime has gettimeofday() defined, while older versions do not. If you have a problem compiling buildtool with g++, try compiling with: g++ -O3 -DHAVE_GETTIMEOFDAY buildtool.cpp -o btool.exe I guess that later, when most people have the newer mingw, that can be changed to NEED_GETTIMEOFDAY for the Luddites. :-) bob

This is the tool we now use at Logilab for all of our projects (for a year now; we used to use CVS). Mercurial is incredibly fast (git also I guess).

Last call for LGM brochure
by cedric GEMY 02 Mar '07

02 Mar '07

Hi guys We are soon ready to finish the brochure made for LGM. People who are interested can send me the nice artworks and design (in svg if possible) they have made, with credits+licence (use metadata for example). I can't promise it can be put within the brochure but there is a chance. Don't worry if you're not a professional : if you like your work may be others will like it too. For info : the brochure will be ditributed in 4000 ex with graphika which is a high level magazin for graphic designer in canada. The purpose of the brochure is to introduce and promote Inkscape (and others) to this public. Cedric (pygmee)

OK, well one thing we definitely need is a test case for linear gradients with all of the extend modes, (could be much like the recent radial case I added). > The results of testing linear gradients with CAIRO_EXTEND_PAD and rgba > stops are: > acroread - ok but the colors seem to be too dark. > evince - broken, The padded region is opaque when it should have > some transparency. > ghostscript - broken. all opaque colors. no transparency. All I looked at was the output from poppler which the test suite uses. I'm also seeing the colors as too dark, but otherwise the results look quite promising, (again without testing extend modes yet). Here's the reference image (sorry it's so tiny): http://cairographics.org/~cworth/images/linear-gradient-ref.png and here's the rendering of the PDF output: http://cairographics.org/~cworth/images/linear-gradient-pdf-argb32-out.png So that just looks like one simple color scaling issue somewhere. And once we test the extend modes, it would at least be very easy to only turn on native gradients for known-good extend modes. > I have not tested radial gradients. I did now, and it's not too pretty. Here's our reference image: http://cairographics.org/~cworth/images/radial-gradient-ref.png and here's the rendering of the PDF output: http://cairographics.org/~cworth/images/radial-gradient-pdf-argb32-out.png So it looks like there's still a fair amount of work to be done there. Anyway, if anyone wants to help out with this, it would be *greatly* appreciated. I took this quick look to see if there was anything here in a state ready to make it into 1.4, but it looks like there's not. -Carl
