Constructor Detail

ChosenColorWidget

public ChosenColorWidget(ScalarMap smap)
                  throws VisADException,
                         RemoteException

Construct a ChosenColorWidget linked to the color control in the ScalarMap (which must be to either Display.RGB or Display.RGBA and already have been added to a Display). It will be labeled with the name of the ScalarMap's RealType and linked to the ScalarMap's color control. The range of RealType values mapped to color is taken from the ScalarMap's range - this allows a color widget to be used with a range of values defined by auto-scaling from displayed data.

Parameters:

smap - ScalarMap to which this widget is bound.

Throws:

RemoteException - If there is an RMI-related problem.

VisADException - If there is a problem initializing the widget.

ChosenColorWidget

public ChosenColorWidget(ColorMapWidget w)

Wrap a ChosenColorWidget around the specified ColorMapWidget.

Parameters:

w - The ColorMapWidget.

Method Detail

getNumberOfRows

public int getNumberOfRows()
                    throws VisADException

Return the number of rows in the table (3 for an RGB-based table, 4 for an RGBA-based table.)

Returns:

The number of rows.

Throws:

VisADException - If the size of the current table cannot be determined.

getRowLength

public int getRowLength()
                 throws VisADException

Return the table's "resolution" (aka the length of its rows.)

Returns:

The row length.

Throws:

VisADException - If the size of the current table cannot be determined.

addGreyWedgeItem

public void addGreyWedgeItem()
                      throws VisADException

Add the standard "Grey Wedge" item to the list of choices.

Throws:

VisADException - If the size of the current table cannot be determined.

addItem

public void addItem(String name,
           float[][] table)
             throws VisADException

Add a color lookup table to the list of choices.

Parameters:

name - Name of this table.

table - Table of colors.

Throws:

VisADException - If there is a problem with the table.
