I want to include some vector graphics capabilities to Lua Player. This may be useful for other programs as well, so what do you think, if I'll add it to PSPSDK?

There are at least two libraries, which looks like good candidates and which are used in other large projects. But I don't know the libs.

http://www.levien.com/libart/

This looks like a nice small lib, which does just vector graphics and some image scaling operation, with some low level operations, like creating vector paths from bezier paths.

http://cairographics.org/introduction

Looks like a big lib, with font support and nice high level functions, similiar to SVG or postscript.

I seriously doubt pspsdk is the place to put such a port.

Both libs look very cool, not that I've ever used them.

It's also probably worth mentioning that I have submitted a SDL_gfx port to svn. SDL_gfx can rotate/zoom images and draw antialiased gfx primitives, including bezier curves (and has framerate control, whoop!).

Comparing cairo and libarts is a little unfair, the counterpart to libarts is more the GL rendering backend of cairo: glitz. If you compare these two, you'll get a slight advantage for glitz (in terms of lines of code) -- and hardware-accelerated graphics:

$ wc -l glitz-0.4.4/src/*.[hc] glitz-0.4.4/src/egl/*.[hc]
12423 total

$ wc -l libart_lgpl-2.3.3/*.[hc]
13434 total

note: glitz does the compositing, so if you are looking more for a vector primitive renderer you'll go probably better with libarts...

The eyeGT thing is interesting, but looks like it is a commercial library, so I've compiled Libart for the PSP and wrote a sample program. The full source code with EBOOT.PBP for 1.00 and 1.50 firmware:

http://www.frank-buss.de/tmp/libart.zip

Conclusion: it is not usable (or I've done something very wrong), because it needs some 10 seconds for rendering a simple 512x512 bitmap. Now I try Cairo.

just wanted to put in the info that someone already brought eyeGT to psp

maybe this helps? (maybe contact this guy)

I've an alternative ! ;)
I'm one of the developers of Amanith (www.amanith.org), it's a crossplatform opensource framework of classes in ansi c++ for handle vector graphics with powerful modelling functions (like curves cut, joins, flatten, and so on) and in the near future also with a good rendering layer and gfx-vector file format support (SVG, SWF). Amanith is also very portable, we have used only Ansi C++ with STL, so it compile under many environments (linux, freebsd, windows, macosx, irix, solaris) with gcc or visualstudio, on several platforms/processor (we have tested x86 and x86_64 intel machines, g4&g5 mac, mips from sgi, and sparc workstations). Some cool guys are porting Amanith also on BeOs, AmigaOS and MorphOS.
