imgSaveAnimationTypedIo function image

bool imgSaveAnimationTypedIo(Pointer<ImgAnimation> anim, Pointer<SdlIoStream> dst, bool closeio, String? type,)

Save an animation to an SDL_IOStream.

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

If closeio is true, dst will be closed before returning, whether this function succeeds or not.

For formats that accept a quality, a default quality of 90 will be used.

\param anim the animation to save. \param dst an SDL_IOStream that data will be written to. \param closeio true to close/free the SDL_IOStream before returning, false to leave it open. \param type a filename extension that represent this data ("GIF", etc). \returns true on success or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL_image 3.4.0.
