Squares in heatmaps - old post

[Nickos]

Hi all,

I found _almost_ the answer to my problem in this thread -
http://groups.google.com/group/gheat/browse_thread/thread/a18a27b6d9c61ea4

but I am struggling to figure out exactly what to do as I am a python/
pygame novice - I am integrating gheat into a mainly PHP environment.
That aside - can anyone give me a pointer as to how to BLEND_ADD the
(1,1,1) as described in this post by Josh Gross? I can't recompile
pygame as I have no choice in the environment I am working in, so I
need to make the change to gheat. I am guessing the code is somewhere
around here?

for dest in points:
tile.blit(self.dot, dest, None, pygame.BLEND_MULT)

Hope you can help :-)
