pub enum ColorType { L8, La8, Rgb8, Rgba8, L16, La16, Rgb16, Rgba16, Rgb32F, Rgba32F, }
Expand description

An enumeration over supported color types and 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.
§

L8

Pixel is 8-bit luminance

§

La8

Pixel is 8-bit luminance with an alpha channel

§

Rgb8

Pixel contains 8-bit R, G and B channels

§

Rgba8

Pixel is 8-bit RGB with an alpha channel

§

L16

Pixel is 16-bit luminance

§

La16

Pixel is 16-bit luminance with an alpha channel

§

Rgb16

Pixel is 16-bit RGB

§

Rgba16

Pixel is 16-bit RGBA

§

Rgb32F

Pixel is 32-bit float RGB

§

Rgba32F

Pixel is 32-bit float RGBA

Implementations§

source§

impl ColorType

source

pub fn bytes_per_pixel(self) -> u8

Returns the number of bytes contained in a pixel of ColorType c

source

pub fn has_alpha(self) -> bool

Returns if there is an alpha channel.

source

pub fn has_color(self) -> bool

Returns false if the color scheme is grayscale, true otherwise.

source

pub fn bits_per_pixel(self) -> u16

Returns the number of bits contained in a pixel of ColorType c (which will always be a multiple of 8).

source

pub fn channel_count(self) -> u8

Returns the number of color channels that make up this pixel
