I have some code that can read a 24bit bitmap into a buffer, and then save it in a 32 bit per fixel file format, then read it again from there. when i get home I'll mail it to you.
NOTE: has no compression watsoever, did it just so I could store alpha channel info, then realised DDraw doesn't support alpha channel... bummer!

Thanks for your code example! It seems really helpful.

But what datatype is Cor? A struct?

I don´t want that anybody can look at my terrific pictures, so can anyone tell me how to save the pictures in a diffrent format, and then open them.

Sorry, forgot I dindn't send you my typedefs.
Cor in Portuguese means colour, it's just a _int32 (dword).
