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
by julien robert 23 Mar '07

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

mingw/gcc-4.1.2
by Bob Jamison 22 Mar '07

22 Mar '07

Hi, all, For a specific bug I needed fixed (doesn't affect Inkscape, as far as I know), I built mingw cross- and native-compilers with a particular bugfix patch applied. Win32 builders don't need to upgrade unless they want to. However, they do both have the latest win32api and mingw-runtime libs applied. Look for 4.1.2 here: http://inkscape.modevia.com/win32libs bob

Minion font problem
by Vladimir Savic 22 Mar '07

22 Mar '07

I own Adobe FontFolio 8.0 and have strange problems with Minion font family. Those fonts render correctly with GIMP and Scribus, but not Inkscape. If I somehow manage to get them on canvas, they get totally messed up when picking Bold or Italic faces of the same using Font dialog, but not if I use secondary toolbar for the same purpose. Anyone experienced similar problems? Thanks in advance, Vlada

Excellent; I don't know of many who use the nntp interface, but GMANE has been an extremely reliable archive for the list, so I expect it should work quite well. Bryce

Johan goes LIVE for GSoC
by Johan Engelen 22 Mar '07

22 Mar '07

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... Cheers! Johan
