[][src]Struct jpeg_decoder::Decoder

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

JPEG decoder

Methods

impl<R: Read> Decoder<R>[src]

pub fn new(reader: R) -> Decoder<R>[src]

Creates a new Decoder using the reader reader.

pub fn info(&self) -> Option<ImageInfo>[src]

Returns metadata about the image.

The returned value will be None until a call to either read_info or decode has returned Ok.

pub fn read_info(&mut self) -> Result<(), Error>[src]

Tries to read metadata from the image without decoding it.

If successful, the metadata can be obtained using the info method.

pub fn decode(&mut self) -> Result<Vec<u8>, Error>[src]

Decodes the image and returns the decoded pixels if successful.
