Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class ColorMapBase

Returns:

static information for all exported properties

setBrightnessRange

public void setBrightnessRange(double min,
                               double max)

Sets the greyscale range [min, max]. If max < min, then colors will be interpolated from bright to dark

setBrightnessRange

public void setBrightnessRange(DoubleInterval range)

Sets the greyscale range [min, max]. If max < min, then colors will be interpolated from bright to dark

getBrightnessRange

public DoubleInterval getBrightnessRange()

Gets the brightness range

getBrightness

public double getBrightness(double a)

Interpolates a brightness value with parameter a in [0,1]

getColor

public java.awt.Color getColor(double a)

Description copied from interface: ColorMap

Returns an interpolated color

Parameters:

a - input, usually in the range [0,1]

Returns:

the color

getRGB

public void getRGB(double a,
