There are two ways to convert raw RGB data to a picogui bitmap: - If you want to do it as easily as possible, and you don't need exceptional speed, you can prepend a .PPM header in front and use pgNewBitmap(). There is information about this file format at: http://www-info2.informatik.uni-wuerzburg.de/mitarbeiter/wolfram/lehre/bildformate.html - If you need more speed but don't mind managing the potential complexity of translating the bitmap into other formats, you can use a shared memory segment. There is a short SHM demo in the apps directory, and a longer example in SDL's picogui video driver. --Micah On Tue, Mar 18, 2003 at 07:14:46PM +0300, [email protected] wrote: > Hello everybody, > > I would like to create bitmap from raw data.
