Struct RGBAColor

pub struct RGBAColor(pub u8, pub u8, pub u8, pub f64);

The RGBA representation of the color, Plotters use RGBA as the internal representation of color

If you want to directly create a RGB color with transparency use RGBColor::mix

Tuple Fields

0: u8

1: u8

2: u8

3: f64

Trait Implementations

impl BackendStyle for RGBAColor

fn color(&self) -> BackendColor

Get the color of current style

fn stroke_width(&self) -> u32

Get the stroke width of current style

impl Clone for RGBAColor

fn clone(&self) -> RGBAColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Color for RGBAColor

fn to_backend_color(&self) -> BackendColor

Normalize this color representation to the backend color

fn rgb(&self) -> (u8, u8, u8)

Convert the RGB representation to the standard RGB tuple

fn alpha(&self) -> f64

Get the alpha channel of the color

fn mix(&self, value: f64) -> RGBAColor

Mix the color with given opacity

fn to_rgba(&self) -> RGBAColor

Convert the color into the RGBA color which is internally used by Plotters

fn filled(&self) -> ShapeStyle

where Self: Sized,

Make a filled style form the color

fn stroke_width(&self, width: u32) -> ShapeStyle

where Self: Sized,

Make a shape style with stroke width from a color

impl<FloatType> ColorMap<RGBAColor, FloatType> for DerivedColorMap<RGBAColor>

where FloatType: Float + FromPrimitive + ToPrimitive,

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

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<FloatType> ColorMap<RGBAColor, FloatType> for ViridisRGBA

where FloatType: Debug + Float + FromPrimitive + ToPrimitive,

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

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 Debug for RGBAColor

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

Formats the value using the given formatter.

impl Default for RGBAColor

fn default() -> RGBAColor

Returns the “default value” for a type.

impl From<RGBColor> for RGBAColor

fn from(rgb: RGBColor) -> RGBAColor

Converts to this type from the input type.

impl PartialEq for RGBAColor

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