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
