}

Pixel data layout for raw byte input.

Describes channel order, bit depth, and color space interpretation. Use with encode_from_bytes() when working with raw buffers.

For rgb crate types, use encode_from_rgb() which infers layout.

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.

Implementations

impl PixelLayout

pub const fn bytes_per_pixel(&self) -> usize

Bytes per pixel for this layout.

pub const fn channels(&self) -> usize

Number of channels (including ignored channels).

pub const fn is_grayscale(&self) -> bool

Whether this is a grayscale format.

pub const fn is_ycbcr(&self) -> bool

Whether this is pre-converted YCbCr.

pub const fn is_bgr(&self) -> bool

Whether this uses BGR channel order.

pub const fn is_float(&self) -> bool

Whether this is a float format (linear color space).

pub const fn is_16bit(&self) -> bool

Whether this is a 16-bit format (linear color space).

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 Copy for PixelLayout

impl Debug for PixelLayout

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

Formats the value using the given formatter.

impl Eq for PixelLayout

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.
