}

Available on crate feature output only.

The depth (number and type of channels) a pixel in a Layer is composed of.

Variants

OneChannel

A single channel. Obtained when setting "layertype" "scalar" on an OutputLayer.

OneChannelAndAlpha

A single channel with alpha. Obtained when setting "layertype" "scalar" and "withalpha" 1 on an OutputLayer.

Color

An rgb color triplet. Obtained when setting "layertype" "color" on an OutputLayer.

ColorAndAlpha

An rgb color triplet with alpha. Obtained when setting "layertype" "color" and "withalpha" 1 on an OutputLayer.

Vector

An xyz triplet. Obtained when setting "layertype" "vector" on an OutputLayer.

VectorAndAlpha

An xyz triplet with alpha. Obtained when setting "layertype" "vector" and "withalpha" 1 on an OutputLayer.

FourChannels

An quadruple of values. Obtained when setting "layertype" "quad" on an OutputLayer.

FourChannelsAndAlpha

An quadruple of values with alpha. Obtained when setting "layertype" "quad" and "withalpha" 1 on an OutputLayer.

Implementations

impl LayerDepth

pub fn channels(&self) -> usize

Returns the number of channels this layer type consists of.

pub fn has_alpha(&self) -> bool

Returns `true`` if this layer contains an alpha channel.

Trait Implementations

impl Clone for LayerDepth

fn clone(&self) -> LayerDepth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerDepth

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

Formats the value using the given formatter.

impl Default for LayerDepth

fn default() -> LayerDepth

Returns the “default value” for a type.

impl PartialEq for LayerDepth

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

impl Copy for LayerDepth

impl StructuralPartialEq for LayerDepth
