Hi Christoph Sounds like a good idea. http://gpwiki.org/index.php/SDL:Tutorials:Displaying_a_Bitmap_from_a_Custom_Resource_File_using_SDL_RWops This web page shows you what you need to do in C. So what you'd need to do is load the bmp or png as a binary file into an array of bytes. When you load your image you need to allocate an array of unsigned char, using cffi, and copy the lisp byte array into this one, as I don't think SDL will like the binary format of the lisp array. The you should be able to copy this roughly into lispbuilder-sdl calls... SDL_RWops *rw = SDL_RWFromMem(buffer, filesize); SDL_Surface *temp = SDL_LoadBMP_RW(rw, 1); Something like this (setf rw (sdl-cffi::sdl-rw-from-mem buffer size)) (setf temp (sdl-cffi::SDL-Load-BMP-RW rw 1)) Hope this helps, Justin _______________________________________________ application-builder mailing list [email protected] http://www.lispniks.com/mailman/listinfo/application-builder
