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.

circle and polyline elements
by Alexandre Prokoudine 16 Mar '09

16 Mar '09

Hi, Some of our extensions create polyline (WMF importer, IIRC) and circle (create_from_triangle.py) elements which are not directly supported, thought rendered in Inkscape. I wonder what the plan for suporting them is, because right now when you have e.g. a circle element, you cannot edit it and you cannot even change its style. Alexandre

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

Problem with our stream writing
by Jon A. Cruz 14 Mar '09

14 Mar '09

I was tracking down bug #340451 and it turns out to be more pervasive than I thought: https://bugs.launchpad.net/inkscape/+bug/340451 The problem is that things are casting 16-bit Unicode values to bytes by chopping all but the last 8 bits. I'm going to be working on fixing this, but it is such a fundamental issue that I'm surprised we're not seeing more issues. Also I'll need to test a few more things and make sure I don't break more than I fix. In the Java world they address this by having a very explicit difference between characters and bytes. Bytes are 'byte' and handled by "OutputStream"s whereas characters are 'character' and are handled by "Writer"s. So I'll just get some tests fixed and then clean up with proper transformations. If anyone can take a look for things that might be a problem, related bugs, things I should test, etc. that would help. Thanks.

Yes. The version 0.46, for instance, isn't shipped with UniConvertor which is used for opening CDR (v0.47 will). > I can send through a list of the file types in particular if that helps.

Google's Summer of Code 2009
by Joshua A. Andler 12 Mar '09

12 Mar '09

Hey all! Our application for this year's GSoC has been submitted. Last years info page has been rolled over to this year with a few minor updates. If people would like to take a look and perhaps edit the page as they see fit that would be excellent. http://wiki.inkscape.org/wiki/index.php/Googles_Summer_Of_Code_2009 As soon as there is any further info or news I will keep the list up to date. Cheers, Josh
