public auto namedColour(in string name)

Convert a name (string) into a Nullable!colour.

Internally calls std.experimental.colorFromString and names supported are therefore exactly the same. This inludes all the colors defined by X11, adopted by the W3C, SVG, and other popular libraries.

alias ColourGradientFunction = RGBA delegate(
    double value, 
    double from, 
    double till)

public ColourGradientFunction colourGradient(T)(
    in ColourGradient!T cg, 
    bool absolute = false)

Function returning a colourgradient function based on a specified ColourGradient

Parameters

cg	A ColourGradient
absolute	Whether the cg is an absolute scale or relative (between 0 and 1)

Examples

auto cg = ColourGradient!HCY();
cg.put( 0, HCY(200, 0.5, 0) ); 
cg.put( 100, HCY(200, 0.5, 0) ); 
GGPlotD().put( colourGradient( cg ) );

public ColourGradientFunction colourGradient(T)(string name)

Function returning a named colourgradient.

Colours can be specified with colour names separated by dashes: "white-red" will result in a colourgradient from white to red. You can specify more than two colours "blue-white-red". "default" will result in the default (blueish) colourgradient.

Examples

GGPlotD().put( colourGradient( "blue-red" );

Deal with colour related struct/functions, such as ColourSpaces etc.
