What's the internal format of .png? RGBA? Other? I've looked in the books I have, and on the web and can't seem to find a definate answer.



Thanks,

It isn't hard to find...

google PNG

navigate to the latest spec
http://www.w3.org/TR/2003/REC-PNG-20031110/

Look up the colour stuff for answers to your specific RGBA? question

Note that colour profiles and gamma correction are also part of the standard.
