imgCreateAnimationEncoder function image

Pointer<ImgAnimationEncoder> imgCreateAnimationEncoder(String? file)

Create an encoder to save a series of images to a file.

The file type is determined from the file extension, e.g. "file.webp" will be encoded using WEBP.

\param file the file where the animation will be saved. \returns a new IMG_AnimationEncoder, or NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL_image 3.4.0.
