Here a quick proof of concept I wrote to try it out: Using my old API I wrote a script that made various shapes and did some selections moved things around etc. Then I ran it twice and saved the file each time (as svg) and ran a diff. No difference but the filename, just as I had hoped. Worried that lots of floating point math would be it's downfall, I used the same technique with scripts that generate these images: http://www.cs.grinnell.edu/~bergsore/dimond-fractal.jpg http://www.cs.grinnell.edu/~bergsore/morph.jpg (They are jpegs here but you can imagine how messy the paths are.) It worked perfectly. Obviously this won't catch errors in the way Inkscape displays things, like bitmap comparisons, but if automated it would be very quick. A fast and easy alternative regression test could definitely be one of my deliverables. What do you guys think? Soren Berg

Re: [Inkscape-devel] Rendering problem for an object with blur / 0.46 Official vs 209225 vs 20967
by worms invasion 29 Mar '09

29 Mar '09

Hi, I'll try to explain better what I mean with a new screenshot: http://www.corpsmoderne.net/~eve97/vertex/rocket_bug/display_inkscape_046_v… First, I'd like to state a few things: - I'm not an artist, but I draw things in Inkscape, and I draw them in SVG to have them displayed as SVG. So my "visual perception" of SVG is what Inkscape shows to me, not a PNG (which I often not even generate). It means I design the object *as I see it rendered on Inkscape canvas*. - I have several drawings made with 0.46 or previous versions of Inkscape, and there are many places where I could download SVG designed with that (openclipart, etc.) So, let's take the following hypothesis: - After seeing a nice SVG in my browser, I download or open in Inkscape 0.47 a file which was drawn with a previous 0.46 version, in order to use it as a clipart, or to rework on it. On the top of the screenshot, it is a shape drawn in Inkscape 0.46, with filter quality set to average (default). It is what I see in my browser, or on the PNG if I generate it. My 0.47 Inkscape is set to default for both Blur display and Filter display, as I have a small machine (512Mb memory, Intel Pentium III mobile, 1133Mhz). I open the file, and I see what shows at the bottom of the screenshot. I hope you'll admit that it is awful and doesn't look like at all what shows in my browser. BUT it is what I work on, I have no other way to work on SVG. I'm not switching back and forth to PNG or to the browser to check what it looks like there. What am I supposed to do at this point? Remember, I'm an average user, not knowning the Inkscape internals. A) I say: this Inkscape program is mad, I'm not going to use it. I close it, end of story. B) I could try to change the blur quality and/or the filter quality to better or best. OK, I do that. But the problem is, the canvas is not updated when I do that, and it's a general preference, not a per-document preference. So, first, I'll have to: - with my document still opened, change the Blur / Filter effect and see that what is displayed on canvas has not changed. - close the document and Inkscape, reopen Inkscape which now has Blur and Filter set to better or best, and see that the file looks like what it should. (or something similar, because I have no idea of the exact real value of the quality). SO: setting the displays to a "lower" average quality in Inkscape 0.47 than in Inkscape 0.46, which was supposed to be intentional to help the designer (the designer in Inkscape 0.47) conserve CPU, results in fact in obliging me (who opened on older file) to set Inkscape to high quality, for all my documents. And I have a small machine - I can't afford to do that. C) I could just do what I was adviced to in the channel: remove the filters on the object. This means I need to find all objects with blur/filter, one by one, and remove that. After such a tedious task, then I lose the original information (here, the blur was 0.3), meaning I am absolutely unable to re-create or re-see the original file, as the artist designed it. What am I supposed to do now? For all the reasons explained above, I think that, although done with the best intention, the fact that the blur/filter display "average quality" has changed results in the opposite effect as the one intended. It seems to me that, at the moment, there are more SVG "done with 0.46" than "done with O.47', and that the case I am describing will arrive for a long, long time... If I missed an obvious point, I'd very much like to hear it.

GSOC: Interested in joining Inkscape
by sonali mendis 29 Mar '09

29 Mar '09

Hi, I'm Sonali Mendis from University of Moratuwa, Sri Lanka. I went through the project ideas listed at Inkscape page and I think it is a great project of my interest. I'm a graphic designer plus a developer and I think and I want to add my ideas and effort to improve this open source project. While using Inkscape, I thought *Guide Improvement *is essentially needed. In addition to that I have another my own idea of introducing different brush types with ability to increase and decrease the size by click of a key while drawing to the pencil tool and introduce an eraser tool with the same options. I need your kind feed back on the ideas mentioned above to select one which will benefit the Inkscape most. Thanking You, Regards, Sonali Mendis

Blurry Icons Problem on OSX
by André Berg 29 Mar '09

29 Mar '09

Hi, In the latest build from source on OSX (rev 21007) 95% of all user interface icons continue to be totally blurred. I submitted a screenshot in an earlier thread which, if it interests you, can be viewed here: http://img102.imageshack.us/img102/9260/inkscape20798osx105inte.png I understand that this is probably not at the top of the priority list. On that end, I would like to just ask two questions: 1. Is this normal for the current OSX builds or is this tied to my environment only? 2. Is there something I can do to revert back to rev. (approx) 20600 behaviour? At least until this has been fixed. As I understand, the icon engine was radically changed. Thank you very much for reading! André

[GSoC] kidscape and NFT dialog ideas!
by Jesus Mager 27 Mar '09

27 Mar '09

HI! My name is Jesus Mager. I am Computer Science Student in Mexico, and I wanna apply in this GSoC for Inskape. But I cant decide what idea I will choose to work on. May be the list can help me: Kidscape I was working with kids software, so: The kid-version of inkscape is a real important idea in the idea list so i con work on it? (In blueprint ti appear as a low priority) If yes: should it be a independent branch of the project, may be a separate project or should it be a option in the same inkscape. (I think the first is the best) The idea is make it for kids in what sense: easier, fashionable, lighter?? I saw the possible GUI: It only seems to do it for netbooks, and lighter platforms. But if the main idea is make it for kids: what about make a cooler kid-friendly interface... may be like tuxpaint (www.tuxpaint.org)? Any idea? New From Template dialog Is it a better option than kidscape? Should it only be the interface, or may be also a guitool to make new templates (dynamical)?? I hope you can give me a orientation to find the appropriate idea and clarify my questions. Bests Jesus Mager

Rendering problem for an object with blur / 0.46 Official vs 209225 vs 20967
by worms invasion 27 Mar '09

27 Mar '09

Hello, I have opened a file which I had done originally with 0.45.1 with the latest win32 snapshot (rev 20967) and there is a problem of rendering in Inkscape. The most obvious object is a simple object with fill and stroke solid colours, and a blur of 0.3. You'll find, for each version that I tested: - the object extracted from the original file, in svg - a screenshot of the rendering in the chosen Inkscape verion - the PNG exported by the said version. In all three versions, the filters/blur parameters were set to average (the default). I'll put them on my server so everyone can see the differences. There is also a zip of the 9 files to download. In short: the exported PNG appears correct in the three versions, but the screenshots of the rendering in Inkscape look very (or very) different across versions. The file looks absolutely normal, as I draw it, in 0.46 official. In r20225, the object is already badly rendered in Inkscape. In r20967, it's awful... How will the user figure out what do draw, or what will happen when a file made with 0.46 will be opened in a later version? Which one is correct to draw?

Logo for SVG Open 2009
by Jon A. Cruz 26 Mar '09

26 Mar '09

Hello all, I just wanted to put out that SVG Open 2009 is looking for header graphics for their new website... which is about to go live. SVG Open 2008 had a subtle header with outlines of the castles in Nuremberg, so is probably not good for this year's conference in California. If anyone is interested, this is a great opportunity to showcase both SVG and Inkscape. I believe that the site will be able to serve SVG directly for browsers that support it.

Guide editing by mouse
by Maximilian Albert 21 Mar '09

21 Mar '09

Hi, as a kind of test for some other things I have in mind I added better support for editing guides by mouse. You will notice that the anchor point of guides is now displayed on canvas as a small dot. You can still move guides as you used to, but now you can also rotate them around the anchor as well as move the anchor along the guide. What I'm not really happy with, though, is the way in which the various functionalities are accessed. So I'd like your help in this respect. Currently it works as follows: 1) dragging the anchor moves the whole guide (and the anchor with it) 2) pressing Shift and dragging the anchor moves it along the guide (while the guide itself stays in place) 3) dragging the guide anywhere outside the anchor rotates it around the anchor 4) pressing Shift and dragging the guide outside the anchor bypasses rotation and moves the whole guide (as in 1.) Does this make sense to you? Do you have better suggestions as to which functionality should be accessed in which way/with which modifier? Thanks for your feedback, Max

[NEW] Icon theming
by Krzysztof Kosiński 20 Mar '09

20 Mar '09

All icons used in Inkscape should now be themable. You can find out the names by looking at the IDs in icons.svg, at icon names in in share/icons/hicolor/scalable/*, or at the file src/ui/icon-names.h. All names are defined in a new file, ui/icon-names.h. This file should be used for all icon names used in Inkscape. I also removed stale files which attempted to do the same but weren't used universally (ui/stock.h, ui/stock-items.h, inkscape-stock.h). Right now Inkscape uses the discrete SVG icons. I timed "hot" startup (using "time inkscape --verb FileQuit" twice and noting the second run) and it seems that it's actually faster (9.281s) than using icons.svg (9.799s), probably because the RSVG renderer which renders the SVG icons in Gnome is faster than ours.

markers
by jf barraud 20 Mar '09

20 Mar '09

Hi, I've had to use markers in inkscape recently and found them very frustrating: putting the markers in the middle of the semgents instead of intermediate nodes is much better in many cases. Consider a path made of horizontal and vertical segments: to show an orientation on it, you'd like to add little arrows at the middle of the segments, definitely not at the corners. I know this contradicts the svg specification, wich has good reason to do so (in patricular, I guess the middle of a segment is not so well defined...) Then I came to the following minimal suggestion: would it make sens to refine the svg spec to avoid/allow markers at smooth/angular points? Even in this case, this wont be a perferct solution: in many cases, I'd like to have only one arrow at the middle of each smooth piece, even if that piece requires many points to be drawn. I don't see any svg compilent way to achieve this. Any suggestion? we could have lpe generated markers, more or less like what "pattern along path" does, with improved placement of the pattern (= markers), but I don't like this solution, as it is not natural to use lpe to do a "stroking decoration"... Cheers, jfb.

These 4 people could then put some effort in the development of ICC, each one working on its own project and giving feedback to the other project. Last year I had to interact often with cairo and pango guys because my project did depend on a new feature of these libs (userfonts). But they didnt seem to have clear deadlines for this feature. Even nowadays we still dont have userfonts feature integrated into libpango. Having "sister SoC projects" could be a way of addressing this kind of issue. JucaBlues

These are the ideas that I am interested: # Font editing and creation features. to continue my previous SoC work. # Multiple Page support it is a much wanted feature in the users community, but it is not that much exciting at all for me to implement... # ICC Color Management for cairo outputs - Would allow Inkscape to produce CMYK PDFs and PSs with Cairo. That is an exciting feature and also a much resquested one. I've played a bit with icc in inkscape sometime ago. The only issue here is that we will probably depend on further developments in cairo API, right? I was also thinking about implementing support for the animation features in SVG. Anyone interested in mentoring me? Last year I got a bit frustrated with my mentor because we haven't had too much interaction. I'd like to be mentored by someone who is often available on IRC and willing to interact in a daily basis. I feel much more productive when I have constant feedback on my work. It would be good to see more detailed descriptions of the proposed ideas. JucaBlues

Early freeze
by bulia byak 18 Mar '09

18 Mar '09

Hi all, for previous releases, we had a two-stage freeze: first, feature freeze (no new features, only bugfixes), followed by full freeze for a short time and then a release. This time, I propose that we start even earlier with an even milder freeze: a _refactoring freeze_ which blocks any wide-ranging, deep-going refactorings that are not focused on adding a specific feature or fixing a specific bug. In particular, this means no lib migrations, no rewriting and rearranging code "for general correctness", and no 2geom syncs "just in case" until the release. I realize this is all done for good reasons, but experience shows that each such wave of changes brings bugs that keep popping up long after the wave has passed. So, if there are no objections, let's finish and commit any refactorings that are pending, and set a date after which we will only be allowed to commit focused, easily testable features and bugfixes. -- bulia byak Inkscape.

No blur on zero area bbox items
by unknown＠example.com 15 Mar '09

15 Mar '09

Hi all, In Jabber someone mentioned that no blur is applied on horizontal and vertical lines. I tried and it is true. I think it is caused by a 'zero area' geometric bbox for horizontal and vertical lines. Could someone with more knowledge of the whole filter rendering chain look into this? I think sp-item.cpp, line 648, "SPItem::GEOMETRIC_BBOX" should be changed to the bbox calculation including stroke width. Thanks, Johan
