Do you have to use bitmap files with DirectDraw? Can you make your own file loader that then can be blitted to a surface? Plz tell me how to do this... I know how to make the file format, just not how to blt it once it is loaded. --------------------

I can''t get into specifics right now (I''m extremely busy at work), but you would load the file, and put it pixel by pixel onto the generic surface (according to whatever formats/rules your file contains). At that point, all surfaces are stored in DIB format, so you would blit like normal from the surface to the backbuffer, and then do the flip (you would only need to do the PIXEL by PIXEL thing when the sprite''s surface was created). Note that you WOULDN''T create this type of file as a resource -- you would need to load it manually during run-time.

Sorry I can''t go into it in more depth (if you email me, i should be able to describe it better tomorrow)

I use the intel JPEG library to load my JPEG based bitmaps to a DirectDraw Surface.

U would need:
1) To download the Intel JPEG (IJL) library from intel.com. (its free)
2) create your own routine to read the JPEG file via the IJL library straight into a DDraw surface.

If u want, I can give u the source code I made.
