Does Pyweek enforce one? If not choose whatever suits you most.

Speaking of which. Are we expected to use Pygame1.9 or Pygame2 for the Pyweek?

No need to use pygame2 for gfxdraw, it's in pygame.

yeah, pygame is still going.  But might be renamed to pygame10... or pygame12 ;)

Yes. Currently there are no plans to drop pygame.

They already use different names, (pygame --> package pygame, pygame2 -->
package pygame2), so they can be installed at the same time without
influencing each other.

gfxdraw is from pygame2, I assume?
Thanks Rene, I'll give it a try.  Pygame2 looks quite awesome.  Is the 1.9
branch gonna keep being maintained when pygame2 is official?  it breaks
backwards compatibility, I guess, are you just going to keep it with a
different name so they can be installed together?

Hi,

please see:  pgyame.gfxdraw.aacircle(surface, x, y, r, color): return None

cheers,

Yes, it is included in pygame2, and uses the SDL_gfx library-

 Thanks for the quick response, Ian.  Been a fan of your work for a while,
hope to see you in PyWeek next month!  I'll give the lib a try and if I end
up needing to / being able to optimize it somehow I'll let you know.  I'll
also post if I come up with a better solution but I'll likely just use your
lib.
Thanks again!

Hi--I wrote some code that makes an anti-aliased circle in my PyGame
Graphics 
Library.
It essentially does a box blur on a circle.
