Struct AvifEncoder

pub struct AvifEncoder<W> {
    inner: W,
    encoder: Encoder,
}

AVIF Encoder.

Writes one image into the chosen output.

Fields

inner: W

encoder: Encoder

Implementations

impl<W: Write> AvifEncoder<W>

pub fn new(w: W) -> Self

Create a new encoder that writes its output to w.

pub fn new_with_speed_quality(w: W, speed: u8, quality: u8) -> Self

Create a new encoder with a specified speed and quality that writes its output to w. speed accepts a value in the range 1-10, where 1 is the slowest and 10 is the fastest. Slower speeds generally yield better compression results. quality accepts a value in the range 1-100, where 1 is the worst and 100 is the best.

pub fn with_colorspace(self, color_space: ColorSpace) -> Self

Encode with the specified color_space.

pub fn with_num_threads(self, num_threads: Option<usize>) -> Self

Configures rayon thread pool size. The default None is to use all threads in the default rayon thread pool.

impl<W: Write> AvifEncoder<W>

fn set_color(&mut self, _color: ExtendedColorType)

fn encode_as_img<'buf>( fallback: &'buf mut Vec<u8>, data: &'buf [u8], width: u32, height: u32, color: ExtendedColorType, ) -> ImageResult<RgbColor<'buf>>

Trait Implementations

impl<W: Write> ImageEncoder for AvifEncoder<W>

fn write_image( self, data: &[u8], width: u32, height: u32, color: ExtendedColorType, ) -> ImageResult<()>

Encode image data with the indicated color type.

The encoder currently requires all data to be RGBA8, it will be converted internally if necessary. When data is suitably aligned, i.e. u16 channels to two bytes, then the conversion may be more efficient.

fn set_icc_profile( &mut self, icc_profile: Vec<u8>, ) -> Result<(), UnsupportedError>

Set the ICC profile to use for the image.
