Enum PixelFormat 

#[non_exhaustive]
pub enum PixelFormat {
    Gray,
    Rgb,
    Rgba,
    Bgr,
    Bgra,
    Cmyk,
}

Pixel format for input/output data.

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.

Gray

Grayscale, 1 byte per pixel

Rgb

RGB, 3 bytes per pixel

Rgba

RGBA, 4 bytes per pixel (alpha is ignored for encoding)

Bgr

BGR, 3 bytes per pixel

Bgra

BGRA, 4 bytes per pixel

Cmyk

CMYK, 4 bytes per pixel

Implementations

impl PixelFormat

pub const fn bytes_per_pixel(self) -> usize

Returns the number of bytes per pixel.

pub const fn num_channels(self) -> usize

Returns the number of color channels (excluding alpha).

pub const fn color_space(self) -> ColorSpace

Returns the corresponding color space.

Trait Implementations

impl Clone for PixelFormat

fn clone(&self) -> PixelFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelFormat

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

Formats the value using the given formatter.

impl Default for PixelFormat

fn default() -> PixelFormat

Returns the “default value” for a type.

impl Hash for PixelFormat

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

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 for PixelFormat

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

Tests for self and other values to be equal, and is used by ==.

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

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