imgLoadAnimationTypedRw function

Pointer<ImgAnimation> imgLoadAnimationTypedRw(Pointer<SdlRWops> src, int freesrc, String? type)

Load an animation from an SDL datasource

Even though this function accepts a file type, SDL_image may still try other decoders that are capable of detecting file type from the contents of the image data, but may rely on the caller-provided type string for formats that it cannot autodetect. If type is NULL, SDL_image will rely solely on its ability to guess the format.

If freesrc is non-zero, the RWops will be closed before returning, whether this function succeeds or not. SDL_image reads everything it needs from the RWops during this call in any case.

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

\param src an SDL_RWops that data will be read from. \param freesrc non-zero to close/free the SDL_RWops before returning, zero to leave it open. \param type a filename extension that represent this data ("GIF", etc). \returns a new IMG_Animation, or NULL on error.

\since This function is available since SDL_image 2.6.0.
