Struct StreamingDecoder

pub struct StreamingDecoder { /* private fields */ }

GIF decoder which emits low-level events for items in the GIF file

To just get GIF frames, use crate::Decoder instead.

Implementations

impl StreamingDecoder

pub fn new() -> StreamingDecoder

Creates a new streaming decoder

pub fn update<'a>( &'a mut self, buf: &[u8], write_into: &mut OutputBuffer<'_>, ) -> Result<(usize, Decoded), DecodingError>

Updates the internal state of the decoder.

Returns the number of bytes consumed from the input buffer and the last decoding result.

pub fn last_ext(&self) -> (AnyExtension, &[u8], bool)

Returns the data of the last extension that has been decoded.

pub fn current_frame_mut(&mut self) -> &mut Frame<'static>

Current frame info as a mutable ref.

pub fn current_frame(&self) -> &Frame<'static>

Current frame info as a ref.

pub fn width(&self) -> u16

Width of the image

pub fn height(&self) -> u16

Height of the image

pub fn version(&self) -> Version

The version number of the GIF standard used in this image.

We suppose a minimum of V87a compatibility. This value will be reported until we have read the version information in the magic header bytes.
