SDL_Surface *IMG_Load_RW(SDL_RWops *src, int freesrc)
Load src for use as a surface. This can load all supported image formats, except TGA.
SDL_RWops is not covered here, but they enable you to load from almost any source.
Note: If the image format loader requires initialization, it will attempt to do that the first time it is needed if you have not already called
IMG_Init to load support for your image format.
Note: If the image format supports a transparent pixel, SDL_image will set the colorkey for the surface. You can enable RLE acceleration on the surface afterwards by calling:
SDL_SetColorKey(image, SDL_RLEACCEL, image->format->colorkey);
Returns: a pointer to the image as a new
SDL_Surface. NULL is returned on errors.
