Constructor Detail

ImageSequenceImpl

public ImageSequenceImpl(FunctionType type,
                         SingleBandedImage[] images)
                  throws VisADException,
                         RemoteException

Create an image sequence with the specified FunctionType.

Parameters:

type - new type for the sequence. The FunctionType of all the images must be the same as the range of type and the domain must be RealType.Time.

images - array of images to be in the sequence

Throws:

VisADException - not the correct MathType or images have different MathTypes.

RemoteException - couldn't create the remote object

ImageSequenceImpl

public ImageSequenceImpl(SingleBandedImage[] images)
                  throws VisADException,
                         RemoteException

Create an image sequence from an array of images

Parameters:

images - array of images to be in the sequence. The FunctionType of all the images must be the same.

Throws:

VisADException - images have different FunctionTypes.

RemoteException - couldn't create the remote object
