impl<'a, R: Read + 'a> AnimationDecoder<'a> for GifDecoder<R>

fn into_frames(self) -> Frames<'a>ⓘNotable traits for Frames<'a>impl<'a> Iterator for Frames<'a> type Item = ImageResult<Frame>;
Consume the decoder producing a series of frames.

sourcefn dimensions(&self) -> (u32, u32)
fn dimensions(&self) -> (u32, u32)
Returns a tuple containing the width and height of the image
sourcefn color_type(&self) -> ColorType
fn color_type(&self) -> ColorType
Returns the color type of the image data produced by this decoder
sourcefn into_reader(self) -> ImageResult<Self::Reader>
fn into_reader(self) -> ImageResult<Self::Reader>
Returns a reader that can be used to obtain the bytes of the image. For the best
performance, always try to read at least scanline_bytes from the reader at a time. Reading
fewer bytes will cause the reader to perform internal buffering. Read more
sourcefn read_image(self, buf: &mut [u8]) -> ImageResult<()>
fn read_image(self, buf: &mut [u8]) -> ImageResult<()>
Returns all the bytes in the image. Read more
sourcefn original_color_type(&self) -> ExtendedColorType
fn original_color_type(&self) -> ExtendedColorType
Retuns the color type of the image file before decoding
sourcefn total_bytes(&self) -> u64
fn total_bytes(&self) -> u64
Returns the total number of bytes in the decoded image. Read more
sourcefn scanline_bytes(&self) -> u64
fn scanline_bytes(&self) -> u64
Returns the minimum number of bytes that can be efficiently read from this decoder. This may
be as few as 1 or as many as total_bytes(). Read more
sourcefn read_image_with_progress<F: Fn(Progress)>(
self,
buf: &mut [u8],
progress_callback: F
) -> ImageResult<()>
fn read_image_with_progress<F: Fn(Progress)>(
self,
buf: &mut [u8],
progress_callback: F
) -> ImageResult<()>
Same as read_image but periodically calls the provided callback to give updates on loading
progress. Read more
