Save a surface to a seekable SDL data stream in BMP format.
int SDL_SaveBMP_RW(SDL_Surface *surface, SDL_RWops *dst, SDL_bool freedst);
|surface||the SDL_Surface structure containing the image to be saved|
|dst||a data stream to save to|
|freedst||if SDL_TRUE, calls SDL_RWclose() on
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
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.
This function is available since SDL 3.0.0.
