rma.util.ColorContour

rma.util.BandedColorContour

All Implemented Interfaces:

AsciiSerializable, FieldAccessor, Serializable, Cloneable

public class BandedColorContour
extends ColorContour

This Color Contour gives "bands" instead of a gradient. For example: Set Blue at 0.0f, Red at 25.0f, and Green at 50.0f, and then: * A value less than zero will return the default color * A Value greater than or equal to zero but also less than 25 will return Blue * A value greater than or equal to zero but also less than 50 will return Red * A value greater than or equal to 50 will return Green

Method Details

buildSwtBandedColor

public static BandedColorContour buildSwtBandedColor()

getIndexes

public NavigableSet<Double> getIndexes()

fetches the set of double used as indexes for colors

Returns:

the set of doubles that are the current color index values

setColorAtIndex

public Color setColorAtIndex(double index,
 Color color)

Sets the color which starts at a value

Parameters:

index - The value at which the color should start

color - The color which is being set

Returns:

The previous color (if any) that was at the value

getColorAtIndex

public Color getColorAtIndex(double index)

Get the color for a value. If Red is set at 0, all values above zero will return Red, and any below will return the default value.

Parameters:

index - The index that the color should start at

Returns:

The color to be set

removeColorAtIndex

public Map.Entry<Double,Color> removeColorAtIndex(double colorIndex)

Remove a color for a given index

Parameters:

colorIndex - The index

Returns:

An Entry containing the removed color and the minimum value for the color

clearColors

public void clearColors()

Remove all colors, leaving just the default color

setDefaultColor

public void setDefaultColor(Color color)

This is the default value for when there is no value below the requested one. If this is set to Blue, no other colors are set, then all requests will return Blue. If this is set to Green and Red is set at 0, all requests below zero will return Green and all requests greater than or equal to zero will return Red.

Parameters:

color - The new default color

getRGB0

 double minValue,
 double maxValue)
