Hi! I'd need to use bitmaps rendered with the graphics toolkit as OpenGL textures in a GL context created by a foreign library (like GLFW, for example). I was looking through the documentation but couldn't any information on how to bind Racket bitmaps as GL textures. The SGL examples seem to do a byte-by-byte copy of a Racket byte-vector acquired with get-argb-pixels which seems redundant and slow since I assume the bitmap is already stored in some format that could be directly used by OpenGL texture creation functions.
So, is there a way to get a foreign pointer to the bitmap data (and format information) or is there some other way to accomplish what I'd need? -- tomppa ____________________ Racket Users list: http://lists.racket-lang.org/users
