Re: [pygame] multi-width aalines and aacircles
very cool module :)
I uploaded some png's for people to see:
However, with ubuntu SDL_gfx I get this error:
>>> import pygame.gfxdraw
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/lib/python2.5/site-packages/pygame/gfxdraw.so: undefined symbol: arcRGBA
I guess arcRGBA isn't in the version I have... which is version 2.0.13 - a pretty a old SDL_gfx (current is 2.0.19pre).
So... I'll try and start submitting bug reports to distros for them to update SDL_gfx. However that won't help us for 1-2 years -- by the time they process the bug report, then finally get around to packaging the newer version - then time for people to upgrade their distros... Also, I think we'll probably try and get some newer fixes into SDL_gfx, so for now including it with pygame is probably better.
Instead, can we include SDL_gfx parts in with pygame? including the whole directory in src/SDL_gfx/ .
I changed Setup to this, which compiled and worked:
GFX = src/SDL_gfx/SDL_gfxBlitFunc.c src/SDL_gfx/SDL_gfxPrimitives.c
gfxdraw src/gfxdraw.c $(SDL) $(GFX) $(DEBUG)
Instead of including it in src/... we could put it in branch/SDL_gfx and put a svn external to src/SDL_gfx (SDL_gfx doesn't appear to use public version control). Or we could just include the needed files needed. I think a branch with svn external to src/SDL_gfx would be best... then it's nicely separated. Then when we release a source tar.gz/.zip we include it with the pygame sources.

You can see for yourself:
Because of a bug aapolygon_gfx.py will not work with the gfx enabled Windows binaries I have provide. The latest Pygame out of SVN is needed. But you can still look at the images I took from a screen shot.

The results actually look good though, if one first draws the outline, then the filled version. Circles not quit so good, but better than with no anti-aliasing.
You could do a filled polygon and then an aa one around it...
But I think then you'd be getting a lot slower...

The aa polygon is not filled, and the filled polygon does no aa.

there's an aa-polygon in sdl gfx
