###### (This function is part of SDL_image, a separate library from SDL.) # IMG_GetAnimationDecoderFrame Get the next frame in an animation decoder. ## Header File Defined in [](https://github.com/libsdl-org/SDL_image/blob/main/include/SDL3_image/SDL_image.h) ## Syntax ```c bool IMG_GetAnimationDecoderFrame(IMG_AnimationDecoder *decoder, SDL_Surface **frame, Uint64 *duration); ``` ## Function Parameters | | | | | ---------------------------------------------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [IMG_AnimationDecoder](IMG_AnimationDecoder) * | **decoder** | the animation decoder. | | SDL_Surface ** | **frame** | a pointer filled in with the SDL_Surface for the next frame in the animation. | | Uint64 * | **duration** | the duration of the frame, usually in milliseconds but can be other units if the [`IMG_PROP_ANIMATION_DECODER_CREATE_TIMEBASE_DENOMINATOR_NUMBER`](IMG_PROP_ANIMATION_DECODER_CREATE_TIMEBASE_DENOMINATOR_NUMBER) property is set when creating the decoder. | ## Return Value (bool) Returns true on success or false on failure and when no more frames are available; call [IMG_GetAnimationDecoderStatus](IMG_GetAnimationDecoderStatus)() or SDL_GetError() for more information. ## Remarks This function decodes the next frame in the animation decoder, returning it as an SDL_Surface. The returned surface should be freed with SDL_FreeSurface() when no longer needed. If the animation decoder has no more frames or an error occurred while decoding the frame, this function returns false. In that case, please call SDL_GetError() for more information. If SDL_GetError() returns an empty string, that means there are no more available frames. If SDL_GetError() returns a valid string, that means the decoding failed. ## Version This function is available since SDL_image 3.4.0. ## See Also - [IMG_CreateAnimationDecoder](IMG_CreateAnimationDecoder) - [IMG_CreateAnimationDecoder_IO](IMG_CreateAnimationDecoder_IO) - [IMG_CreateAnimationDecoderWithProperties](IMG_CreateAnimationDecoderWithProperties) - [IMG_GetAnimationDecoderStatus](IMG_GetAnimationDecoderStatus) - [IMG_ResetAnimationDecoder](IMG_ResetAnimationDecoder) - [IMG_CloseAnimationDecoder](IMG_CloseAnimationDecoder) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategorySDLImage](CategorySDLImage)
