imgLoadApngAnimationIo function image

Pointer<ImgAnimation> imgLoadApngAnimationIo(Pointer<SdlIoStream> src)

Load an APNG animation directly from an SDL_IOStream.

If you know you definitely have an APNG image, you can call this function, which will skip SDL_image's file format detection routines. Generally, it's better to use the abstract interfaces; also, there is only an SDL_IOStream interface available here.

When done with the returned animation, the app should dispose of it with a call to IMG_FreeAnimation().

\param src an SDL_IOStream from which data will be read. \returns a new IMG_Animation, or NULL on error.

\since This function is available since SDL_image 3.4.0.
