Struct image::jpeg::JPEGEncoder

pub struct JPEGEncoder<'a, W: 'a> { /* fields omitted */ }

The representation of a JPEG encoder

Methods

impl<'a, W: Write> JPEGEncoder<'a, W>

fn new(w: &mut W) -> JPEGEncoder<W>

Create a new encoder that writes its output to w

fn new_with_quality(w: &mut W, quality: u8) -> JPEGEncoder<W>

Create a new encoder that writes its output to w, and has the quality parameter quality with a value in the range 1-100 where 1 is the worst and 100 is the best.

fn encode(&mut self,
          image: &[u8],
          width: u32,
          height: u32,
          c: ColorType)
          -> Result<()>

Encodes the image image that has dimensions width and height and ColorType c

The Image in encoded with subsampling ratio 4:2:2
