NEW: color effects extensions
by bulia byak 16 Nov '06

16 Nov '06

Contributed by Jos Hirth, with some changes by me: * Color effects: a new group of extensions in the Color submenu of the Effects menu allows you to adjust all colors of a selection at once. These commands affect both fill and stroke colors, including gradients (but not bitmaps). The commands include Brighter and Darker (adjust brightness by up or down by 10%), Desaturate, Grayscale, Negative, commands for removing or swapping the Red, Green, Blue channels, as well as a Custom command where you can set your own formulas for modifying the color channels. These extensions are a temporary solution; in a future version, similar functionality will be added to Inkscape core. Adjusting gradient colors may be buggy because a gradient is sometimes shared by more than one object. Also, undoing color changes on gradients exposes a bug where an object seems to "disappear"; this is however only a display issue (probably caused by the order in which gradients and their users are restored on undo) not causing any loss of information. Finally, on large documents and large selections with gradients, Python's XPath code may get quite slow. Despite these shortcomings, I decided to commit this, because it's genuinely useful functionality which was so far missing in Inkscape. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

SSE2 optimized compositing functions
by Jasper van de Gronde 15 Nov '06

15 Nov '06

Some time ago I wrote versions of a (small) number of compositing functions (from libnr/nr-compose.cpp) using SSE2 (with intrinsics), but I'm not sure how I should integrate them with Inkscape code (separate file? compile settings? ...?). Also, if there is anyone who has some experience with SSE2 I wouldn't mind if they took a look (I don't have very much experience with writing SSE2 and it's quite possible that I'm not achieving optimal performance). BTW, I have code for: nr_R8G8B8A8_P_R8G8B8A8_P_R8G8B8A8_N_A8 nr_R8G8B8A8_P_EMPTY_R8G8B8A8_N_A8 nr_R8G8B8A8_P_R8G8B8A8_P_R8G8B8A8_P And it could probably be adapted to variants of those functions. The SSE2 versions are approximately 2 times as fast as the normal versions (on my machine, a P4).

new Buildtool stuff for win32
by Bob Jamison 15 Nov '06

15 Nov '06

Hi all, I've been working on a project to replace all of our old aging Makefile.mingw and the Makedep stuff for win32 builds. From the years when I worked in Java, I learned to love the Ant build tool and how it automates many tasks, and replaces a lot of shelling out for trivial tasks (copy, mkdir, delete, etc). So I made this Buildtool thing vaguely similar to Ant. It is of course infinitely less powerful than that mature project. But the basic theory of operation is the same. And if there is ever any new feature or function we need, we can easily code it into the tool. So, instead of requiring Perl, we have a single .cpp file and a build descriptor file, "build.xml," which currently is the only file it needs for a complete Inkscape build. To run the thing, merely do: g++ buildtool.cpp -o build.exe There are no dependencies. Then compile with "build" or clean up with "build clean" I see no reason that an alternative build.xml could not be made for running on Unix, also. bob

openraster
by Alexandre Prokoudine 15 Nov '06

15 Nov '06

Hi, This is a quick reminder for Inkscape developers that OpenRaster project has been evolving [1] thanks to Cyrille Berger of Krita team and Øyvind Kolås of GEGL/GIMP teams for quite a while now. The project was mentioned in this list early in March this year. I've just checked again and it turned out that it wasn't really much discussed. Here is a short overview. OpenRaster aims to become an OpenDocument format (ODR) for multilayered raster graphics with clipping paths, masks, layer effects etc.. It is going to become a standard for exchanging of project data between users of different applications. Repesentatives of several opensource projects have expressed their interest in supporting this file format by providing either exporting or importing (or both) filters for it, when this standard is approved by respective OASIS TC as such (or even earlier). Krita/SVN and GEGL/CVS HEAD already have initial supporting code. There is a draft document from June 2006 available [2] to read. In case of Inkscape this task might be quite simple, since it can already write OpenDocument Draw documents, and exporting an Inkscape SVG document to ODR, when ODR is ready, would be a matter of exporting each layer to a respective PNG file and combining them into ODR layers, with clipping paths or masks where applicable (some effects like Gaussian blur could be exported to an effect layer, too, possibly by means of XSLT), then saving it to a ZIP archive (sure, I oversimplify this description :)). If any of Inkscape developers is interested in supporting this file format in the future (especially since it is going to have basic vector graphics capabilities) -- at least exporting to it, the team would appreciate your input. Most discussions are held in CREATE mailing list [3].

Hi, Just for my curiousity, does the -G option (start with gtkmm UI) still make sense? Alexandre

The contest was theorically closed today, but don't know were the result are and the The ccHost contest admin tools link is dead (or not born yet) : http://openclipart.org/wiki/Contests#Contest_1_-_Inkscape_0.45_About_Screen Has anyone received submissions ? Could this contest be extended another month to take benefits of new functions ?

Re: [Inkscape-devel] NEW: Trace Bitmap dialog redesign and new parameters

One thing though - would it be better to have the preview not in it's own tab but to double the width (or height) of the window and have the preview separate to the two tabs? Otherwise the steps are Adjust->Change tab->Update->Change tab->Adjust etc instead of Adjust->Update->Adjust... Cheers Derek

I would maintain consistency with the transparency range of values: from 0.00 to 1.00 with 2 digits precision.
