Struct DisplayFunction

pub struct DisplayFunction { /* private fields */ }

A multi-channel screen transfer function

Implementations

impl DisplayFunction

pub fn name(&self) -> Option<&str>

A common name used to distinguish this display function from others or describe its behavior. May contain any valid Unicode.

pub fn r(&self) -> &STF

Screen transfer functions for the red channel of an RGB image

pub fn k(&self) -> &STF

Screen transfer function for the single channel of a grayscale image – just an alias for Self::r()

pub fn g(&self) -> &STF

Screen transfer functions for the red channel of an RGB image

pub fn b(&self) -> &STF

Screen transfer functions for the red channel of an RGB image

pub fn l(&self) -> &STF

Screen transfer function for grayscale/luminance previews of an RGB image

Do not use this for grayscale images! This STF is only meant to be used for grayscale previews of color images. For grayscale images, Self::k() should be used instead.

Trait Implementations

impl Clone for DisplayFunction

fn clone(&self) -> DisplayFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayFunction

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

Formats the value using the given formatter.

impl Default for DisplayFunction

No name and identity STFs for each channel

fn default() -> Self

Returns the “default value” for a type.

impl Index<usize> for DisplayFunction

Allows transparent access to the per-channel STF

type Output = STF

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for DisplayFunction

Ignores the name, just compares the single-channel STFs

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

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

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

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