Expand description

An enumeration over supported color types and their bit depths

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Gray(u8)

Pixel is grayscale

RGB(u8)

Pixel contains R, G and B channels

Palette(u8)

Pixel is an index into a color palette

GrayA(u8)

Pixel is grayscale with an alpha channel

RGBA(u8)

Pixel is RGB with an alpha channel

CMYK(u8)

Pixel is CMYK

CMYKA(u8)

Pixel is CMYK with an alpha channel

YCbCr(u8)

Pixel is YCbCr

Multiband

Pixel has multiple bands/channels

Fields

§bit_depth: u8

§num_samples: u16
