GSoC Entry - Inkscape Web Exporter
by Alex Trujillo 03 Apr '10

03 Apr '10

Hey folks. I've been using Inkscape for years, and I couldn't think of a better project to join for my first GSoC. I've written up a proposal on an exporter of vector graphics for various web standards. I have experience using those various web standards over the years, most of which are documented on Google Code. I just wanted to run this by you guys before I submitted it, since I've read something to the tune that some of the best proposals have come from those who have sought community support. Here's the link to the proposal on Google Docs (as a public document) http://docs.google.com/Doc?docid=0AcePN-K69iVuZDI2ajlmYl85MjhjaHhyYnhndw&hl… Nanoblok is a project I've been working on my own for a while: http://code.google.com/p/nanoblok/ My personal website, where I have a great deal of graphics I've made in Inkscape: http://infokraft.org/ I even have an Inkscape tutorial on there I did not too long ago! Well, please lend me your questions and comments! - Alex

Re: [Inkscape-devel] Filter effect and blur background

(This is regarding "discontinuities" appearing in blurs, when using BackgroundImage.) Ivan Louette wrote: > Thanks Jasper ! > > Try Yann's file I sent back ; it breaks some times and sometimes not... > > ivan I have indeed been able to reproduce the problem, and found a few copy-paste bugs in Gaussian blur (which normally wouldn't be triggered, and as such went unnoticed) in the process. But the real problem seems to be with the way in which the background image is accessed. In essence the background image doesn't take the area enlargement into account that is needed to correctly render the blur. To properly fix this would probably require a few more changes than I'm comfortable with at this stage in the release cycle, and could take a while anyway, so I've filed a bug (+associated rendering test): https://bugs.launchpad.net/inkscape/+bug/554649

Re: [Inkscape-devel] GSoC - transformation anchors - before apply

Hello, Thank you for all feedback a few days ago. I basically have some understanding about the project, which may allow me to start the proposal. In this weekend, I will write a proposal for the project, "Transformation anchors", with all information that I have got, and my ideas in planning. Should I submit it or send it to the mailing list for some feedback first? I will put some responses below...

I definitely will consider them into the plan. I see the possibility to work on these after completing the transformation anchor project, perhaps one or both of them. If there is no time to finish all of these in three months, I will try to make sure on-going work is easy to do. After the three months of work, I may be interested to continue the work, if I have time. Basically, I will do some planning that includes all these relevant tasks. At some point later, it may become clear what can be done. > ------------------------------ > > Message: 5 > Date: Fri, 26 Mar 2010 23:09:30 +0300 > From: Alexandre Prokoudine <alexandre.prokoudine@...400...> > > On 3/26/10, Pajarico wrote: > > > * 2) allow math operations (like sum, substraction, multiplication, > > division) inside the spin boxes for Height, Width, X, Y; and now I > > would add center of transformations. > > Just steal code from GIMP 2.7.0+ :) > > Alexandre > > Cool. I guess I can do that. Stealing from open source is something that I have done for many times, both for Master thesis and at-work programs. Recently, I took some code for spline interpolations into my thesis. Taking code from Gimp should not be too difficult to me. Translating it into C++ is doable too. I do porting of different languages on daily bases. Regards, Zhenfeng.

XDG User Dirs
by Krzysztof Kosiński 02 Apr '10

02 Apr '10

Hello While taking a stab at fixing the command line on Windows, I can also implement the XDG User Dirs specification, using relevant GLib functions. However, there is a slight problem with this: we currently look for user data (palettes, extensions, etc.) in the user's config directory, not in the data directory. The default user config directory on Unix is ~/.config, while the default user data directory is ~/.local/share. Is it OK to look in .local/share? We can automatically create a README in the config directory on the first run that tells the user to move his datafiles to ~/.local/share/inkscape. Regards, Krzysztof

New memebr and a bug (maybe)
by CoD 01 Apr '10

01 Apr '10

Hello, I'm a 31 years old developer from Italy and I've been using Inkscape for years. I've just subscribed to this mailing list and.. yeah... I'm already here with a bug report :P Recently I experienced a strange behaviour with KDE 4 preview system and svg/svgz files saved with the last version of inkscape (both stable and devel version) so I decided to contact you. I hate duplicate/unclear bug reports so I would like to discuss this thing a bit with you before filing a bug to launchpad. So, let's try to explain what I've found System: Kubuntu 9.10 with KDE 4.3.2 Inkscape: devel version and 0.46 (See below) Reproducible: yes These are the steps I did: 1) I drew a simple icon with inkscape (a circle and a polygon) 2) I save it as svg or svgz (get the file here [1]) 3) The preview on my kubuntu 9.10 looks crazy (get the preview here [2]) as if nodes position has been screwed 4) I open the svg file with Inkscape 0.46 5) I change the color of an element and save again 6) The preview still looks crazy 7) I open the file again with Inkscape 0.46 but this time I move the polygon around, then I place it in the old position and save 8) The preview looks perfect, as if nodes position has been restored (get the file and the preview here [3][4]) I can't really understand what's going on here but seems that KDE 4 has troubles when previewing svg/svgz files saved with inkscape > 0.46 This happens also using ksvgtopng to convert an svg file to a png Could this possibly be related to bug 170049 [5] ? If you need more experiments just ask :-) Thank you Claudio Canavese (CoD) 1: http://cod-web.net/inkscape/devel.svgz 2: http://cod-web.net/inkscape/devel.png 3: http://cod-web.net/inkscape/046.svgz 4: http://cod-web.net/inkscape/046.png 5: https://bugs.launchpad.net/inkscape/+bug/170049

Curve Sketching
by Ilya Baran 01 Apr '10

01 Apr '10

Hi, I've developed an algorithm for fitting smooth curves (the curves are like in Spiro, but piecewise-linear curvature) to user sketches. I'm thinking that this could be useful in Inkscape as a replacement or alternative to the current pencil tool algorithm. Compared to existing stuff, the benefit is that the curves are usually much nicer, the drawback is that it's a complicated algorithm and is slower--fitting a curve of moderate complexity will likely take about 1 second. Would the Inkscape devs be potentially interested in including this functionality? I'm looking into rewriting my research prototype to be faster, cleaner, more robust, and to remove proprietary dependencies. I can write the library that does the fitting, but I'm unfamiliar with Inkscape's code base, so I'd need help integrating it in. The time frame is that I'd likely be done with the library by the middle of summer. My paper with details and comparisons to existing methods (including Inkscape) at the end is at http://www.mit.edu/~ibaran/curves/ The reported timings can probably be improved by close to a factor of 2. Thanks, -Ilya

Yes, this is oversketching--it's not a new idea, but I haven't seen it implemented well in a full product (and my implementation in the prototype is not great either). Integrating this feature into Inkscape would be to a large extent a UI issue--and I'm not the best person to figure those out :) > Without having read the paper, what does this implementation look like > in terms of number of nodes/points created? We currently have a > smoothing option for the pencil tool, and when you choose to make it > smoother, it reduces the number of nodes used (and also reduces > accuracy). Yes, in producing the Inkscape examples, I tried tuning the smoothing option as well as I could. The central idea of my algorithm is to solve a global optimization problem explicitly minimizing the number of curve segments, subject to accuracy constraints, so in general it produces relatively few segments. The examples in the paper have the curve segments color coded, so you can see exactly which ones are produced. > Are you at all familiar with lib2geom?

As far as I can tell, it's based on these S-basis things, to which I haven't been able to find a great introduction--I think I understand them well enough to conclude that converting my splines to this representation (approximately) should be relatively painless. Regardless, I want my library to be standalone (and I need, for example, Eigen for high-performance linear algebra--so I'll use it for vectors in general to make my life easier), but if it makes sense to interface with Inkscape through lib2geom, then that's the way to go. > I'd recommend checking out lib2geom if you have a chance, compiling it, > and checking out the many "toys" that it has... your demo video feels > somewhat like the toys that they create (basically the proof of concept > before things are attempted in Inkscape).

Moving ahead in inkscape development..
by Abhishek Sharma 31 Mar '10

31 Mar '10

Hello all, I had previously introduced myself as a GSOC 2010 aspirant. I am devoting myself to the idea of c++ifying(in Object Oriented manner) the inkscape code. For that I am trying to move into the code and traversing, but due to its vastness am facing problems in it. I got hold of a very old bug, "Y Scale inversion" -> https://bugs.launchpad.net/inkscape/+bug/170049. As i have seen the heat on this, this bug is of a very wide scope and so can actually help me to involve myself with *much* of the inkscape codebase. So it is my urgent and honest request to inkscape developers as well as corresponding GSOC mentors to just direct me as to where in the code I should start tracking and removing the bug. I will be glad. Thanking You. Yours sincerely, -- Abhishek Sharma B-Tech Information Technology Indian Institute of Information Technology(Amethi Campus)

Filter effect and blur background
by Yann Papouin 31 Mar '10

31 Mar '10

Hi, Please first take a look at this picture composited in photoshop: http://ftpmerou.free.fr/inkscape/blur-background.png I tried to reproduce the same effect in inkscape easilly, and i made it by using a copy of the picture, bluring it and applying a mask with a shape to simulate the effect: http://ftpmerou.free.fr/inkscape/blur-background-fakebymask.svg It's ok now, but I thought about filter effects (background image can be used as a connection link in the filter editor) and saw this: http://www.w3.org/TR/SVG/filters.html#AccessingBackgroundImage On http://wiki.inkscape.org/wiki/index.php/Filter_Effects there is a note about this property "There's no GUI for setting the enable-background property. This property has to be set on some parent layer of filtered object to make Background Image and Background Alpha input images work." Does the background image support is implemented? Do you think that the same effect can be achieved with filters by applying the effect on a shape (that will blur its background content)?

I have checked the file. The problem cause was an absence of font engine in old UniConvertor versions. We have refactored sK1 and UniConvertor code base and font engine now in common sk1libs package. These changes will be in UniConvertor 1.1.5. So just waiting for the release. Thank you for provided sample. It allows us improving some CGM filter related issues.

GSOC spatial indexing - renderer
by Vangelis Katsikaros 29 Mar '10

29 Mar '10

Hello I have briefly described in the past my thoughts on how the render can be improved by introducing spatial indexes. The render has to find which shapes intersect with the user's viewport. Currently this is done by a full scan in display/sp-canvas.cpp:871 in sp_canvas_group_render() right? (Krzysztof gave some hints in another thread some days ago). The idea is to implement an index, so that the renderer performs the range query faster than the full scan. Some basic ideas on the project. * The index is going to be a standard one like R-star (used in oracle, postgis, sqlite). * This R-trees can support 3 dimensions without any performance penalty (if the index has many dimensions performance deteriorates and other kind of indexes perform better). If we do this project we can implement a third dimension (time), for future usage, and leave it there until Inkscape goes into animation. * It would be better if the project is hosted in lib2geom. In this way Inkscape's code base undergoes the minimal changes (ideally no more than a few lines of code). * The index should be disk based (so that it can be saved and reused when Inkscape opens the same file again) * There should be a way to identify the shapes of the SVG uniquely (either XML elements or elements from another abstraction Inkscape uses). Can anyone give me some pointers on how I should work for this issue? Any ideas are welcome.

by Joshua A. Andler 29 Mar '10

29 Mar '10

Hey all, I propose moving to Frost on Tuesday if nobody opposes. To be clear, the main delay in moving forward was an improper usage of Poppler and it blocking us from having "make check" being run. Thank you to Krzysztof for addressing our poppler issue, and Ted for pushing forward with the "check" issues (both make and dist). Given that the main hurdle has been jumped over, I'm comfortable saying that we should push forward to Frost now. We are NOT at Feature Freeze and we don't need to uber-restrict commits yet... but we need to tone down the "radical" nature of commits. Frost will have us achieve: Most development complete. Release Notes should be >90% filled in. Bug Hunt: 300 points Post inkscape-0.48-alpha.tar.gz The following outstanding issues are being actively worked on: *Krzysztof's Node Tool rewrite bugs and issues. *Jon's wicked custom Swatch issues. *Tavmjong's LinuxFund text tool work. The following outstanding issues HAVE to be addressed to not be cut: *Jon's swatches MUST be initially editable in the F&S dialog. *Jon's new Input Devices dialog needs whatever polish to be good enough. *Jon's "UX" work (specifically UI placement should be looked at). *Tavmjong's LinuxFund text tool work (yes it hasn't been committed, but we can only accept so much depending on when code lands). *Felipe Sanches' color management work. The "not real" (device) cmyk thing MUST be addressed prior to release. I'm not saying to remove, but perhaps disable, it is a part of the SVG spec, but it's not how the CMYK workflow actually works. Notes: Tavmjong's work can thankfully be pulled in partially... if we have new and working widgets for the text tool, we should take them when available rather than wait. Jon has put an extraordinary amount of effort into refactoring stuff for the swatches. 0.48 is a multi-point release in that we're anticipating 0.49 dev to be lengthy... if there are bugs (which are committed to be worked on), I'm not against a release with them. No offense, but, we're just like every software vendor out there in this case saying that we know there are issues and are committed to fix them... but feeding our audience takes priority. If you have any issues, comments, or something to address... please speak up! Cheers, Josh

Feature Suggestion: Automatic layer size adjustment
by Michael Grosberg 29 Mar '10

29 Mar '10

I think it would be nice if some GSOC student were to work on such a feature: Currently you can't draw outside a layer's boundary, and you have to tell GIMP to adjust the boundary yourself. I think an option can be added that, when set to "on", lets GIMP handle that in such a way: 1. any time a layer is moved, GIMP will after the operation set the layer boundary to include the entire canvas. 2. On save, GIMP will autocrop all layers. what do you think?

Axonometric grid scaling bug
by Radek 28 Mar '10

28 Mar '10

Hello all, some time ago I've encoutered a bug in inkscape resulting in incorrect updating of axonometric grids. I have fixed it myself, then I've filed a bug report with a patch included: https://bugs.launchpad.net/inkscape/+bug/429776 Apparently it hasn't been noticed by any of developers, so I decided to try here. I think that this bug is quite severe for the axonometric grid functionality (conditions in which it appears to be working properly are actually a corner case), it makes the feature hardly usable. I hope that someone will take a look at the bug report and commit the fix. The bug has been reported against 0.46, but I can provide a patch ported to 0.47 if it helps. Radek

GSoC 2010 Cairo canvas
by Krzysztof Kosiński 28 Mar '10

28 Mar '10

Hello all I will limit myself to two possibilities of a GSoC project for this year: Cairo rendering and SP layer improvements. I think they have the biggest potential impact. This mail discusses the first one. In order to use Cairo rendering in Inkscape, we need a Cairo-based canvas widget to replace the current SPCanvas / NRArena. They appear to be originally derived from GnomeCanvas. Canvas widgets are a rather common beast in the FOSS world, so even if we decide none of the existing ones are satisfactory for us, we have a large body of work from which we can derive inspiration. This page has links to several existing canvas implementations. I have not analyzed all of them yet, but will keep you informed about any important http://live.gnome.org/ProjectRidley/CanvasOverview Here are some requirements for our canvas. 0. Based on Cairo. 1. Model/view split: objects displayed on the canvas can exist without it. 2. Widgetless rendering: it should be possible to render completely in memory, for example for console-mode PDF export. 3. No excessive ties to Inkscape - implemented as a library, perhaps using a few well-defined portions of the existing codebase (e.g. 2geom). 4. Canvas primitives should be sufficient to render SVG. There are many things to discuss, but here's the first one: Tiling reduces the area of the screen that needs to be redrawn, but increases the number of drawing operations. We could instead have a tile-less system that would compute the affected bounding box and redraw it in one go, instead of redrawing many tiles. What do you think? Regards, Krzysztof

Node tool & hash maps
by Joshua A. Andler 26 Mar '10

26 Mar '10

I just ran across the following and figured I would pass the link on since it is a comparison of various hash map implementations and their performance. http://incise.org/hash-table-benchmarks.html Are we using unordered w/ integers? If so, we may want to explore other options. Oh, and someone in the notes also pointed out: https://edge.launchpad.net/libmct Cheers, Josh

GSoC (Student Idea) - Graphical Script Extension Editor
by Andrew Simmons 26 Mar '10

26 Mar '10

Hello, I would like to make it easier for Inkscape users to create their own script extensions, especially effects (ie. scripts that operate on the current image). *Ideally* this would involve creating some kind of visual programming language to allow users to drag-and-drop high-level SVG editing commands with intuitive icons into a editor field to create their program - without having to write a single line of code. *Practically* there is no way I could code something so complex in the time-span. Thus I think I should focus on automating as much of the ScriptingHOWTO section as possible. This would (possibly) include: - A graphic tool to generate INX files? - Creating some useful python functions (eg. "addStar()") to allow users to create their script quickly? - An interactive function navigator? Would this be a viable summer of code project? I haven't used GTK+ before nor created an Inkscape extension (yet) Thanks, Andrew Simmons

GSoC - transformation anchors - before apply
by Zhenfeng Zhao 26 Mar '10

26 Mar '10

Hello, I am interested in working on the "transformation-anchors" project in GSOC this year. I am a graduate student in Computer Science in Canada. I knew Inkscape would win GSOC projects this year, as usual. :-) Congrats. I hope it is not too late to say Hi here. Inkscape is one of my favorite open source software. I also have strong interests and work experiences in image processing, image editors. I have developed a vector-based graphics editor from scratch before. That graphics editor uses customized XML formats, have OOP architecture design to deal with all shapes/primitives with object classes, and allow SVG and DXF (Solidworks drawing file) import and export. Therefore, it seems Inkscape GSoC projects are most interesting and relevant to me. The project, transformation-anchors, seems interesting and doable to me. Wiki docs are very helpful. It is impressive that GUI mock-up has already been posted several months before the Gsoc actually starts. I will read and plan in further detail. I have similar work before, to have the default rotation center to be the geometric center of all shapes. Anchor coordinates are a part of the object (drawing) attributes. It can be adjusted, so that geometrical transformations, rotation, translation, scaling, and shearing, can be performed with the updated center. In this project, there will be some GUI modification, e.g. enable and disable buttons, display coordinates and values, take XY input from users, and allow undo and redo. Maybe some nice intuitive and simple designs will help on these. There may be some refactoring to do, but I am not sure. In this stage, I hope to understand more for this project. Please kindly share comments. I will draft a full proposal in about 10 days. Technically, this project seems doable to me. Besides that I am good in C++, which may be a basic requirement, I have done some work using the following. XML: I have used it for many projects, using C++, Python, C# and Java. Libraries used: .NET, DOM, JDOM, Minidom. SVG: I have written a SVG viewer before. GTK+: I have experience with it. It is the most complex GUI widgets that I have used. SVN: I used it at work before.
