Expand description

A vulcanic colormap that display red/orange and black colors

Implementations§

§

impl VulcanoHSL

pub fn get_color<FloatType>(h: FloatType) -> HSLColor
where FloatType: Debug + Float + FromPrimitive + ToPrimitive,

Get color value from VulcanoHSL by supplying a parameter 0.0 <= h <= 1.0

pub fn get_color_normalized<FloatType>( h: FloatType, min: FloatType, max: FloatType, ) -> HSLColor
where FloatType: Debug + Float + FromPrimitive + ToPrimitive,

Get color value from VulcanoHSL by supplying lower and upper bounds min, max and a parameter h where min <= h <= max

Trait Implementations§

§

impl<FloatType> ColorMap<HSLColor, FloatType> for VulcanoHSL
where FloatType: Debug + Float + FromPrimitive + ToPrimitive,

§

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

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

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 this function see get_color_normalized.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
