I want to be able to change the colors of my background image - fade in/out. The image isn''t a 3D texture and is just a regular offscreen surface. Is alpha blending the only way to accomplish this or is there some other method? If alpha blending is the only way I think unless the surface is a 3D texture then alpha blending can''t be used. Also the reason that I''m not using a 3D texture is because the image is really big and not a power of 2 (e.g. 1000x500). Thanks for any help!

If your image is a palettized image it can be done by fading the palette. Otherwise you will most likely have to make your own fade function where you fade each pixel in the image.

I never thought of doing that! Thanks, you''re a lifesaver
