Constructor Detail

ColorMapWidget

public ColorMapWidget(ScalarMap smap)
               throws VisADException,
                      RemoteException

Construct a LabeledColorWidget 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.

ColorMapWidget

public ColorMapWidget(ScalarMap smap,
                      boolean immediate)
               throws VisADException,
                      RemoteException

Construct a LabeledColorWidget 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.

immediate - true if changes are immediately propagated to the associated Control.

Throws:

RemoteException - If there is an RMI-related problem.

VisADException - If there is a problem initializing the widget.

ColorMapWidget

public ColorMapWidget(ScalarMap smap,
                      float[][] table)
               throws VisADException,
                      RemoteException

Construct a LabeledColorWidget 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. The initial color table (if non-null) should be a float[resolution][dimension], where dimension is either 3 for Display.RGB or 4 for Display.RGB) with values between 0.0f and 1.0f.

Parameters:

smap - ScalarMap to which this widget is bound.

table - Initial color lookup table.

Throws:

RemoteException - If there is an RMI-related problem.

VisADException - If there is a problem initializing the widget.

               throws VisADException,
                      RemoteException

Construct a LabeledColorWidget 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).

table - Initial color lookup table.

update - true if the slider should follow the ScalarMap's range.

Throws:

RemoteException - If there is an RMI-related problem.

VisADException - If there is a problem initializing the widget.
