 javax.media.jai.OperationDescriptorImpl
javax.media.jai.operator.URLDescriptor
| URLDescriptor | | public class URLDescriptor extends OperationDescriptorImpl (Code) | | An OperationDescriptor describing the "URL" operation.
The URL operation creates an output image whose source is
specified by a Uniform Resource Locator (URL).
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.
