RemoteException - Java RMI failure.

ImageRGBDisplayable

public ImageRGBDisplayable(String name,
 float[][] colorPalette,
 boolean doAlpha)
                    throws VisADException,
RemoteException

Constructs from a name for the Displayable and the type of the RGB parameter.

Parameters:

name - The name for the displayable.

colorPalette - The color palette

doAlpha - true to map to RGBA

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

ImageRGBDisplayable

public ImageRGBDisplayable(String name,
 float[][] colorPalette,
 boolean doAlpha,
 FieldImpl field)
                    throws VisADException,
RemoteException

Constructs from a name for the Displayable and the type of the RGB parameter.

Parameters:

name - The name for the displayable.

colorPalette - The color palette

doAlpha - true to map to RGBA

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

ImageRGBDisplayable

protected ImageRGBDisplayable(ImageRGBDisplayable that)
                       throws VisADException,
RemoteException

Constructs from another instance. The following attributes are set from the other instance: color palette, the color RealType.

Parameters:

that - The other instance.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Details

loadData

public void loadData(FieldImpl field)
              throws VisADException,
RemoteException

Set the data into the Displayable; set RGB Type

Specified by:

loadData in interface GridDisplayable

Parameters:

field - an image or sequence of images

Throws:

VisADException - from construction of VisAd objects

RemoteException - from construction of VisAD objects

getColorTupleType

public RealTupleType getColorTupleType()

Get the RealTupleType of the RGB parameter.

Returns:

The RealTupleType of the RGB parameters. May be null.

setColorTupleType

protected void setColorTupleType(RealTupleType realTupleType)
                          throws RemoteException,
VisADException

Sets the RealTupleType of the RGB parameter.

Parameters:

realTupleType - The RealTupleType of the RGB parameters. May not be null.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

getRGBRealTupleType

public RealTupleType getRGBRealTupleType()

Returns the RealTupleType of the RGB parameter.

Returns:

The RealTupleType of the color parameter. May be null. deprecated use getColorTupleType()

setScalarMaps

protected void setScalarMaps(ScalarMapSet maps)
                      throws BadMappingException

Sets the set of ScalarMap-s of this instance. The ScalarMap-s of this instance will be added to the set before the SCALAR_MAP_SET property is set. This method fires a PropertyChangeEvent for SCALAR_MAP_SET with null for the old value and the new set of ScalarMap-s for the new Value. Intermediate subclasses that have their own ScalarMap-s should override this method and invoke super.setScalarMaps(ScalarMapSet).

Parameters:

maps - The set of ScalarMap-s to be added.

Throws:

BadMappingException - The RealType of the color parameter has not been set or its ScalarMap is alread in the set.

setAlpha

VisADException,
RemoteException

Set the display.

Overrides:

setDisplay in class Displayable

Parameters:

display - display to set this into

Throws:

DisplayException - Display type exception

RemoteException - Java RMI error

VisADException - problem creating VisAD object

This method sets the color palette according to the color table in argument; pair this method with setRange(lo,high) to get a fixed association of color table and range of values.

Overrides:

setColorPalette in class Displayable

Parameters:

colorPalette - the color table or color-alpha table desired

Throws:
