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`

fn new() -> Self

Creates a new streaming decoder

fn update(&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.

fn last_ext_sub_block(&mut self) -> &[u8]

Data of the last extension sub block that has been decoded. You need to concatenate all subblocks together to get the overall block content.

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

Current frame info as a mutable ref.

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

Current frame info as a ref.

fn width(&self) -> u16

Width of the image

fn height(&self) -> u16

Height of the image

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.
