NAME¶

SDL_LoadPNG_IO - Load a PNG image from a seekable SDL data stream.

SYNOPSIS¶

#include <SDL3/SDL_surface.h>

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

DESCRIPTION¶

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.

FUNCTION PARAMETERS¶

src

the data stream for the surface.

closeio

if true, calls SDL_CloseIO() on src before returning, even in the case of an error.

RETURN VALUE¶

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

THREAD SAFETY¶

It is safe to call this function from any thread.

AVAILABILITY¶

This function is available since SDL 3.4.0.
