Interface ContourPlot.ColorMap

All Known Implementing Classes:

ContourPlot.DefaultColorMap, ContourPlot.SimpleColorMap

Enclosing class:

ContourPlot

public static interface ContourPlot.ColorMap

The ColorMap interface defines discrete mapping from a fixed integer interval [0..N-1] to colors through the getColor(int) method. It also defines a continuous mapping from the unit interval [0,1] to colors through the interpolate(double) method. For this each of the discrete colors is mapped to a location within the unit interval [0,1] with the first color mapping to 0 and the last mapping to 1. The colors in between have arbitrary but ascending locations within ]0,1[ which can be accessed using getLocation(int).

Method Detail

numColors

int numColors()

Returns:

the number of discrete colors in this ContourPlot.ColorMap

getColor

int getColor(int i)

Returns the ith color

Parameters:

i - index of the color

Returns:

ith color in integer packed ARGB format (0xff00ff00 is opaque green)

getColors

int[] getColors()

Returns:

all discrete colors in this ContourPlot.ColorMap in integer packed ARGB format (0xff00ff00 is opaque green)

getLocation

double getLocation(int i)

Returns the location of the ith color within the unit interval.

Parameters:

i - index of the location/color

Returns:

location within [0,1]

getLocations

double[] getLocations()

Returns:

all locations of the discrete colors in this ContourPlot.ColorMap

interpolate

default int interpolate(double m)

linearly interpolates colors for the specified location of the unit interval.

Parameters:

m - location within [0,1]

Returns:

the interpolated color for specified location in integer packed ARGB format (0xff00ff00 is opaque green)

copy

default ContourPlot.SimpleColorMap copy()

Returns:

copy of this color map

resample

default ContourPlot.SimpleColorMap resample(int numSamples,
                                            double start,
                                            double end)

Returns a uniformly sampled version of this map with the specified number of samples within the specified interval.

Parameters:

numSamples - number of uniform samples

start - of sampling interval within [0,1[

end - of sampling interval within ]0,1]

Returns:

re-sampled map
