Constructor Details

Index

public Index(Color[] colors)

Construct a new Index color map.

Parameters:

colors - the array of colors to assign to indices

Index

public Index(Color[] colors,
 int alpha)

Construct a new Index color map with transparency where \(\alpha\in[0,255]\) with \(0\) fully transparent and \(255\) fully opaque.

Note: this is a convenient way to generate maps with a different transparency. The transparency of the supplied colors is always honoured but overruled if alpha != 255.

Parameters:

colors - the array of colors to assign to indices

alpha - the alpha value for opaque colors

the color represented as an object of type T

toGradient1D

public ColorMap.Gradient1D<String> toGradient1D(int nIncr)

Description copied from class: ColorMap.Index
