Enum jpeg_encoder::ColorType

pub enum ColorType {
    Luma,
    Rgb,
    Rgba,

Color types for input images

Available color input formats for Encoder::encode. Other types can be used by implementing an ImageBuffer.

Variants

Luma

Grayscale with 1 byte per pixel

Rgb

RGB with 3 bytes per pixel

Rgba

Red, Green, Blue with 4 bytes per pixel. The alpha channel will be ignored during encoding.

Bgr

RGB with 3 bytes per pixel

Bgra

RGBA with 4 bytes per pixel. The alpha channel will be ignored during encoding.

Ycbcr

YCbCr with 3 bytes per pixel.

Cmyk

CMYK with 4 bytes per pixel.

CmykAsYcck

CMYK with 4 bytes per pixel. Encoded as YCCK (YCbCrK)

Ycck

YCCK (YCbCrK) with 4 bytes per pixel.

Trait Implementations

impl Clone for ColorType

fn clone(&self) -> ColorType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColorType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ColorType

fn eq(&self, other: &ColorType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
