Enum druid::piet::image_crate::ColorType

#[non_exhaustive]
pub enum ColorType {
    L8,
    La8,

}

An enumeration over supported color types and bit depths

Variants (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

impl ColorType

pub fn bytes_per_pixel(self) -> u8

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

pub fn has_alpha(self) -> bool

Returns if there is an alpha channel.

pub fn has_color(self) -> bool

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

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).

pub fn channel_count(self) -> u8

Returns the number of color channels that make up this 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<(), Error>

Formats the value using the given formatter.

impl From<ColorType> for ExtendedColorType

fn from(c: ColorType) -> ExtendedColorType

Converts to this type from the input type.

impl Hash for ColorType

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ColorType> 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.
