Implementations

impl Colormap

pub fn from_name(name: &str) -> Option<Self>

Parse colormap name from string

pub fn apply(&self, value: f64) -> (u8, u8, u8)

Apply colormap to a normalized value (0.0 to 1.0) Returns (R, G, B) values in range 0-255

Trait Implementations

impl Clone for Colormap

fn clone(&self) -> Colormap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Colormap

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

Formats the value using the given formatter.

impl PartialEq for Colormap

fn eq(&self, other: &Colormap) -> 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 Colormap
