Save a surface to a file.
int SDL_SaveBMP(SDL_Surface *surface, const char *file);surface |
the SDL_Surface structure containing the image to be saved |
file |
a file to save to |
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.
