   javax.media.jai.OperationDescriptorImpl
      javax.media.jai.operator.StreamDescriptor

StreamDescriptor
public class StreamDescriptor extends OperationDescriptorImpl (Code)
An OperationDescriptor describing the "Stream" operation.

The Stream operation produces an image by decoding data from a SeekableStream. The allowable formats are those registered with the com.sun.media.jai.codec.ImageCodec class.

The allowable formats are those registered with the com.sun.media.jai.codec.ImageCodec class.

The second parameter contains an instance of ImageDecodeParam to be used during the decoding. It may be set to null in order to perform default decoding, or equivalently may be omitted.

The classes in the com.sun.media.jai.codec package are not a committed part of the JAI API. Future releases of JAI will make use of new classes in their place. This class will change accordingly.
