pub struct JPEGDecoder<R> { /* fields omitted */ }

JPEG decoder

Methods

impl<R: Read> JPEGDecoder<R>[src]

pub fn new(r: R) -> ImageResult<JPEGDecoder<R>>[src]

Create a new decoder that decodes from the stream r

Trait Implementations

impl<R: Read> ImageDecoder for JPEGDecoder<R>[src]

type Reader = Cursor<Vec<u8>>

The type of reader produced by into_reader.

fn row_bytes(&self) -> u64[src]

Returns the number of bytes in a single row of the image. All decoders will pad image rows to a byte boundary. Read more

fn total_bytes(&self) -> u64[src]

Returns the total number of bytes in the image.

fn scanline_bytes(&self) -> u64[src]

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

fn read_image_with_progress<F: Fn(Progress)>(
    self,
    progress_callback: F
) -> ImageResult<Vec<u8>>
[src]

Same as read_image but periodically calls the provided callback to give updates on loading progress. Read more
