(This function is part of SDL_image, a separate library from SDL.)


Save an SDL_Surface into PNG image data, via an SDL_RWops.


int IMG_SavePNG_RW(SDL_Surface *surface, SDL_RWops *dst, int freedst);

Function Parameters

surface the SDL surface to save
dst the SDL_RWops to save the image data to.
freedst SDL_TRUE to close/free the SDL_RWops before returning, SDL_FALSE to leave it open.

Return Value

Returns 0 if successful, -1 on error.


If you just want to save to a filename, you can use IMG_SavePNG() instead.

If freedst is SDL_TRUE, the RWops will be closed before returning, whether this function succeeds or not.


This function is available since SDL_image 3.0.0.
