Re: What's happening with PNG ?

I know some og you are thinking "Hey, this is probably a problem with Photoshop" but it isn't : if I save the original (RGB converted) GIF to a TIFF image, the colors are perfect when I draw the image in my app and when I look at it in Preview !

How exactly does that rule out the possibility that it is a problem with the PNG export/support in photoshop?


There is something strange (I wanted to say "wrong" but maybe that's normal and I don't know why...yet !) with the way MacOSX Tiger draw and display PNG pictures. And this strangeness prevents me from using PNG in my app !

google is your friend...

If someone can help me with this, I'd be glad to hear what's wrong !

"All versions of Photoshop from 5 upward have a known bug that will incorrectly save Gamma values." - http://www.evolt.org/article/ To_PNG_or_not_to_PNG/22/60134/

If you're using a newer version of photoshop this may be related: http://www.wpdfd.com/cgi-bin/yabb/YaBB.pl? board=software;action=display;num=1082967422
