SDL_LoadPNG_IO

Load a PNG image from a seekable SDL data stream.

Header File

Syntax

SDL_Surface * SDL_LoadPNG_IO(SDL_IOStream *src, bool closeio);

Function Parameters

SDL_IOStream *	src	the data stream for the surface.
bool	closeio	if true, calls SDL_CloseIO() on `src` before returning, even in the case of an error.

Return Value

(SDL_Surface *) Returns a pointer to a new SDL_Surface structure or NULL on failure; call SDL_GetError() for more information.

Remarks

This is intended as a convenience function for loading images from trusted sources. If you want to load arbitrary images you should use libpng or another image loading library designed with security in mind.

The new surface should be freed with SDL_DestroySurface(). Not doing so will result in a memory leak.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.4.0.
