Hello! :) I have trouble with alpha! I have a texture, I check every single pixel in loop and if it's black (0,0,0) I set alpha = 0, if it's not exactly black I set alpha = 255. Later, by using Color4f, I try to make my picture gets better visability and there is my problem! I need better visability for picture without background whitch alpha was 0, but Color4f incrases visability for the picture (that's ok) and background that shouldn't be visable! Do You know the way to make background's alpha = 0 forever, without any way to change it? Thanks for any help! :) [Edited by - Gravell on December 10, 2006 1:29:14 PM]

I can't stay with alpha = 0 :( I have to change alpha, but only image's alpha, without background's :/ Is there an easy way to change pixel's alpha (image's pixels, without background's)?

PS I'll add screenshots later, now I'm busy :)
