Thanks,

But when I talk about "raw" I mean a simple RGBA, RGBA,RGBA.... format, 
not the camera format.

I just have a memory block that contains simple RGBA set of pixels and 
need to compress/uncompress them.

To summarie I need to :

1) compress the "unsigned int" (RGBA) into a compressed version in 
memory (without file access)
2) decompress to the same "unsigned int" (RGBA) memory block

How can I do that ? if possible !

Thanks for your help
