Save an SDL_Surface into PNG image data, via an SDL_IOStream.
Defined in SDL_image.h
int IMG_SavePNG_IO(SDL_Surface *surface, SDL_IOStream *dst, int closeio);| surface | the SDL surface to save |
| dst | the SDL_IOStream to save the image data to. |
| closeio | SDL_TRUE to close/free the SDL_IOStream before returning, SDL_FALSE to leave it open. |
Returns 0 if successful, -1 on error.
If you just want to save to a filename, you can use IMG_SavePNG() instead.
If closeio is SDL_TRUE, dst will be closed before returning, whether this function succeeds or not.
This function is available since SDL_image 3.0.0.
