Enum PixelLayout 

#[non_exhaustive]
pub enum PixelLayout {

Describes the pixel format of input 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.

Rgb8

8-bit sRGB, 3 bytes per pixel (R, G, B).

Rgba8

8-bit sRGB + alpha, 4 bytes per pixel (R, G, B, A).

Bgr8

8-bit sRGB in BGR order, 3 bytes per pixel (B, G, R).

Bgra8

8-bit sRGB in BGRA order, 4 bytes per pixel (B, G, R, A).

Gray8

8-bit grayscale, 1 byte per pixel.

GrayAlpha8

8-bit grayscale + alpha, 2 bytes per pixel.

Rgb16

16-bit sRGB, 6 bytes per pixel (R, G, B) — native-endian u16.

Rgba16

16-bit sRGB + alpha, 8 bytes per pixel (R, G, B, A) — native-endian u16.

Gray16

16-bit grayscale, 2 bytes per pixel — native-endian u16.

RgbLinearF32

Linear f32 RGB, 12 bytes per pixel. Skips sRGB→linear conversion.

Implementations

impl PixelLayout

pub const fn bytes_per_pixel(self) -> usize

Bytes per pixel for this layout.

pub const fn is_linear(self) -> bool

Whether this layout uses linear (not gamma-encoded) values.

pub const fn is_16bit(self) -> bool

Whether this layout uses 16-bit samples.

pub const fn has_alpha(self) -> bool

Whether this layout includes an alpha channel.

pub const fn is_grayscale(self) -> bool

Whether this layout is grayscale.

Trait Implementations

impl Clone for PixelLayout

fn clone(&self) -> PixelLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelLayout

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

Formats the value using the given formatter.

impl PartialEq for PixelLayout

fn eq(&self, other: &PixelLayout) -> 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.
