- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class JPEGDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "JPEG" operation.
The "JPEG" operation reads an image from a JPEG (JFIF) stream.
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.
