int SDL_SaveBMP(SDL_Surface* surface,
                const char*  file)

Function Parameters


the SDL_Surface structure containing the image to be saved


the file to be saved to

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Code Examples


    SDL_Surface *sfc = ...

    if(SDL_SaveBMP(sfc, "somefile.bmp") != 0)
        // Error saving bitmap
        printf("SDL_SaveBMP failed: %s\n", SDL_GetError());


Surfaces with a 24-bit, 32-bit and paletted 8-bit format get saved in the BMP directly. Other RGB formats with 8-bit or higher get converted to a 24-bit surface or, if they have an alpha mask or a colorkey, to a 32-bit surface before they are saved. YUV and paletted 1-bit and 4-bit formats are not supported.
