Minor upgrade to autotracing
by Bob Jamison 17 Sep '04

17 Sep '04

A few weeks ago, at the suggestion of one of our fine users, I added a Potrace image-to-vector tracing engine to Inkscape. Initially, it just traced the image according to a hardcoded brightness threshold. Later I added a threshold adjustment. Today, there is a new toy, "Canny Edge Detection", also sometimes called "optimal edge detection." This should help with the tracing of more subtly colored images, and not just by simple brightness. Check it out: http://troi.hous.es3.titan.com/~rjamison/inkscape/files/potrace.png Play with it, break it, etc. Have fun. BTW: Here is the kind of image that 'pov-out' export can make. Our lovely logo, Simpson's-3D style: http://troi.hous.es3.titan.com/~rjamison/inkscape/files/ispov.png Bob

I also submitted a new Freshmeat announcement of it that should be going up soon. https://sourceforge.net/project/showfiles.php?group_id=93438&package_id=130… This is version 0.1 of mod_rsvg that tvon (Tom von Schwerdtner) gave me in 2003. It works with Apache 1.3. I don't plan on maintaining it, but if anyone wishes to submit patches, can roll new releases of it. Bryce

Inkscape helping OpenClipArt.org
by Alan Horkan 16 Sep '04

16 Sep '04

I noticed that we don't have anything to tell Inkscape users that they can get more patterns from the openclipart.org site. Long term there is great potential for collaboration in all sorts of different ways, but I have a simple idea to start with: Presumably Inkscape will ship with at least a few templates, perhaps five small sample gradients, and five small sample patterns. Here is where helping OpenClipArt.org bit comes in - why not just put in a pattern that points people there? It'd be easy to set up, and non-intrusive since only users already looking at the patterns would see it. http://matrix.netsoc.tcd.ie/~horkana/dev/jasc/webdraw/openclipart.org-adver… The whole pattern is a link to http://www.openclipart.org/ Please let me know what you think, I really hope you will accept this suggestion. And thanks Bryce for your help (he knows why, say no more). Sincerely Alan Horkan http://advogato.org/person/AlanHorkan/ Inkscape, Draw Freely http://inkscape.org Free SVG Clip Art http://OpenClipArt.org

NEW: "transform with object" toggle buttons
by bulia byak 16 Sep '04

16 Sep '04

* The preferences that control scaling of stroke widths and rectangle corners, as well as transforming gradient and pattern fills with the object, are now represented by four toggle buttons in the selector's controls panel for easy access. * Gradients no longer behave weird when a path with gradient fill is transformed. Now gradients either transform with the object or remain unmoved, depending on the user setting (toggle button in selector controls). This setting affects grouped objects too.

inkscape in product screenshots
by Robert Crosbie 15 Sep '04

Related to the "inkscape in the news" posts: I find it neet that in the latest releases of KDE 3.3 and Gnome 2.8, you will see inkscape in the product screenshots. Like here for instance, right next to Gimp: http://tinyurl.com/4bu7x Cheers, -- Rob. http://members.rogers.com/rcrosbie

First autobuild since Boehm and <text> fixed on Win32
by Bob Jamison 15 Sep '04

Here is the first attempt at an autobuild since things started working again: http://troi.hous.es3.titan.com/~rjamison/inkscape/builds/Inkscape0409140643… Please let me know if it works. Thanks, Bob

Gdb on win32. was: re: First autobuild, etc
by Bob Jamison 15 Sep '04

15 Sep '04

Notice that there is now a copy of gdb.exe in the install directory. In the future, when testers find a crashing bug, they can instead open a console, cd into the inkscape directory, and type "gdb inkscape" then "run" ... then crash Inkscape, go to the console again, and type "bt" ...and give us the output. If they aren't good at consoles, they can douple-click gdb.exe, and at the 'gdb>' prompt type "target exec inkscape.exe" then "run" ....as before.. This way our testers can be real testers and participants of the project. Several times this has allowed us to fix bugs quickly, and we really appreciate it. Bob

Re: [Inkscape-user] default object behaviours
by Jon Phillips 15 Sep '04

15 Sep '04

I think that the behavior of illustrator in this area is good. Use the last use of the tool's settings for the next use of the tool. Thus if you changed the rectangle from blue to yellow, then the next time one used the rectangle tool, the shape would be yellow.

Freetype2/win32 conversion
by Bob Jamison 15 Sep '04

15 Sep '04

Since I am out for the weekend, I thought I would send some notes to the list about Freetype. Well, it looks as though we are on our own, and must convert to Freetype on Win32, whether we like it or not. So I made a few changes: Added more stuff to gtk24.zip (AGAIN! sorry) to include a freshly-built freetype6.dll, the fontconfig lib, and xmlparse.dll (required by fontconfig). Added WITH_XFT to config.h.mingw, but it is commented out. Freetype will not actually be used unless you uncomment this. I added '-lfontconfig' to the LIBS entry in Makefile.mingw.common. Note: the '-lfontconfig' should be changed to '-lfontconfig-1.0.dll' . This is an error that the original builder of freetype6.dll made, that apparently I duplicated perfectly :) . This is likely the reason that the original dll references "fontconfig", and not "fontconfig.dll" or "libfontconfig-1.0.dll" Both of these are because fontconfig's build erroneously put '-lfontconfig' in its pkg-config file, even though the build is dynamic only. Look in /target/lib for the correct spelling of the .dll.a file. (This is also quite likely the reason for the crasher.) Since the freetype6.dll I made has debug info, the crash reported the location to be at base/ftobjs.c, line 789 in the Freetype source. So to debug, someone might want to try putting breakpoints in FontInstance.cpp, and stepping until the crash happens. A font face * passes a NULL check, but fails a pointer->field reference. Sounds like an uninitialized value. Anyway, these are just some notes that I hope might help someone working on this stuff. Bob
