Expand description

Converts scalar values to colors.

Required Methods§

source

fn get_color_normalized( &self, h: FloatType, min: FloatType, max: FloatType ) -> ColorType

A slight abstraction over get_color function where lower and upper bound can be specified.

Provided Methods§

source

fn get_color(&self, h: FloatType) -> ColorType

Takes a scalar value 0.0 <= h <= 1.0 and returns the corresponding color. Typically color-scales are named according to which color-type they return. To use upper and lower bounds with ths function see get_color_normalized.
