pub struct WebPEncoder<W> { /* private fields */ }

Expand description

WebP Encoder.

Implementations§

source §

impl<W: Write> WebPEncoder<W>

source

pub fn new_lossless(w: W) -> Self

Create a new encoder that writes its output to w.

Uses “VP8L” lossless encoding.

source

pub fn encode( self, data: &[u8], width: u32, height: u32, color: ColorType, ) -> ImageResult<()>

Encode image data with the indicated color type.

The encoder requires image data be Rgb8 or Rgba8.

§Panics

Panics if width * height * color.bytes_per_pixel() != data.len().
