Hey all, Just wanted to let everyone know that Feature & String Freezes are now in effect. Only behind by a day right now, so that's pretty good. :) Translators please do your magic with the confidence that we won't be changing strings. :) Cheers, Josh

Actually the geometry is known (for most LCDs it is RGB) and the direction can be determined by examining xrandr and window position.

The image zoom > software considers images as made of pixel as having the R, G and B I intentionally did not use zooming for the comparison, only displayed the page as-is on two screens, one with the expected RGB direction and one rotated. The reason for crude zooming in bitmap viewers is speed I guess, few people want to wait tens of seconds for their image to show in the viewer. Also without additional information you cannot know how the image was rendered and how it should be scaled or resampled for different subpixel positions and different resolutions. > components on the same point.

The same Working with pixels directly makes sense for very small low resolution images which are more akin to ASCII-art than actual pictures. As the resolution of display devices increases and images are getting more realistic the need for such low-level manipulation decreases as well. Still the low-res images strike back in the form of font glyphs and icons for pocket devices. Actually there is real a problem of converting fonts from vector outlines to some bitmap form which can be used for simple drawing operations (in this particular case for use in a bootloader which should not be concerned with rendering vector graphics). The current method freetype uses fails miserably for conversion to b&w (not grayscale) bitmaps but maybe there is no way how that can be done reasonably. Grayscale is the next thing on the list of things to try but I have not seen the results yet. If your software can render some CJK/Indic/whatever TrueType/OpenType/whatever font glyphs that would be another thing where good antialiasing could be useful. Rendering of Latin or such is also of use but there drawing all the bitmaps by hand is less of an issue and many bitmap fonts already exist. Thanks Michal

Hi, There is a tradition to add blogs of "graphics" GSoC students to graphicsplanet.org every year. If your students blog on their projects, please let me know URLs/RSSs and I'll add them. Thanks, Alexandre Prokoudine http://libregraphicsworld.org

About shapes with translucent borders
by Juan Vuletich 06 Jun '10

06 Jun '10

Hi Folks, Inkscape and other SVG renderes draw shapes by drawing first the fill, and then drawing the border on top. As Ivan noted recently (in ""), at http://dev.w3.org/SVG/modules/vectoreffects/master/SVGVectorEffectsPrimer.h… and http://www.w3.org/TR/SVGTiny12/render.html#PaintingShapesAndText , it is clear that the standard requests to do that. I didn't know that, and took the time to render this svg: http://www.jvuletich.org/Morphic3/rects.svg like this: http://www.jvuletich.org/Morphic3/rectsInM3.png . It is a bit more complicated, but I feel it is better. What do you think? Should I simplify my code and just draw one over the other? Or should the standard be changed, and Inkscape and other renderers do what I did? Thanks, Juan Vuletich

Feature Freeze
by Joshua A. Andler 05 Jun '10

05 Jun '10

Hi all, We're ready to move into Feature Freeze. No further feature work is permitted at this point. Any remaining tasks regarding documentation needs to be wrapped up ASAP, as we will be moving to string freeze soon. Feature Freeze entails: No further development work. Disable features that aren't finished Post additional inkscape-0.48-pre*.tar.gz releases Focus on critical bug fixing. Finalize all tutorials, docs, etc. Finalize all extensions Finalize about screen Translators create translations. Inkscape must pass 'make distcheck' Establish the Stable Branch for release Disable features that won't be turned on in the release Post inkscape-0.48-beta.tar.gz ----- Here's a tentative release schedule (please, lets try to stick to this): Today (6/1) is Feature Freeze Monday (6/7) will be String Freeze Monday (6/21) will be Hard Freeze Monday (6/28) will be Release ----- To stick to this we need to address the following. @Felipe: It appears that either your device-cmyk work needs to get disabled at this time, which was suggested by Jon in the previous thread. Will you be able to address this soon? Please let us know. Bug 542346 @Jon: Please get the "UX" selector in that toolbar sorted ASAP. Are the "Auto" swatches initially editable in the F&S dialog yet? If not, it's looking like they'll need to be disabled again for this release. @Johan: I see you think you've fixed the LPE issue that bulia reported, thank you! @Tavmjong: Awesome work on the Text Tool! Is there anything else that is a "must" to get in/fixed? If so, is it looking feasible to get done in time with your schedule? Also, it appears that bug 583593 is assigned to you, any progress? If there are any other issues that have been overlooked please let me know. Thanks to everyone for all of your hard work! Cheers, Josh

Emergency save could need testing
by Jasper van de Gronde 05 Jun '10

05 Jun '10

I took the liberty of fixing a bug that would cause pretty much any autosave of a document that has already been saved before to fail: https://bugs.launchpad.net/inkscape/+bug/283769 I have tested with multiple files, new documents, existing documents and existing documents which were the result of an emergency save. Given that the release is slowly nearing I would love at least some confirmation that it also works on Linux(/Mac), as I've only tested on Windows. The attached file demonstrates some changes I used to add a Crash menu item to the file menu, as I didn't know of any other way to make Inkscape crash fast and reliably :) Also, if anyone can give the code a quick review that would be great as well (see revision #9470 and/or inkscape.cpp in trunk).

Gradient with beziercurves....
by Axel Richter 04 Jun '10

04 Jun '10

Hi Devs, i think, the gradientool are great and useful, but this could be more advanced. Nice function are the points on the gradientline, but the line should be handle in the second mode like a curve or bezier. every point should the graident tagential to the line or curve. the other option could be possible to convert the bezier-tool into a gradienttool. please all devs help me or take me the way to great this funktion. i like inkscape and i think this is the number one of vector-tools.

mingw, freebsd cross build patches
by Jan Nieuwenhuizen 03 Jun '10

03 Jun '10

Hi, Last year I added Inkscape to our GUB cross build tool so that it creates installers for windows and some Linux/FreeBSD flavours. Inspired by the grand LGM event, today I've updated the patches to latest trunk, for mingw: inkscape-mingw.patch inkscape-wstring.patch for freebsd: inkscape-isfinite.patch inkscape-round-2.patch inkscape-wstring.patch In order to enable cross building, you also need to fix the hard setting of the PKG_CONFIG variable in configure.ac, the GUB builds scripts now have self.file_sub ([('AC_PATH_PROG\(PKG_CONFIG,', 'AC_PATH_PROG(ARE_YOU_FREAKING_MAD__OVERRIDING_PKG_CONFIG,')], '%(srcdir)s/configure.ac') as PKG_CONFIG is set to something like 'PKG_CONFIG': '''pkg-config \ --define-variable prefix=%(system_prefix)s \ --define-variable includedir=%(system_prefix)s/include \ --define-variable libdir=%(system_prefix)s/lib \ ''', Greetings, Jan. -- Jan Nieuwenhuizen <janneke@...570...> | GNU LilyPond http://lilypond.org Freelance IT http://JoyOfSource.com | Avatar® http://AvatarAcademy.nl

Power Stroke discussion
by unknown＠example.com 03 Jun '10

03 Jun '10

Hi all, This summer, Zhenfeng will work on a new "variable stroke width" LivePathEffect, called "Power Stroke". Now that Zhenfeng has started his GSoC, I'd like all who are interested to join the discussion on this page: http://wiki.inkscape.org/wiki/index.php/PowerStroke#Discussion_at_LGM_20 10. Already I got some great input at the Libre Graphics Meeting in Brussels last week. More input is always welcome. Thanks a lot! Johan
