public class PNMDescriptor

extends OperationDescriptorImpl

An OperationDescriptor describing the "PNM" operation.

The "PNM" operation reads a standard PNM file, including PBM, PGM, and PPM images of both ASCII and raw formats. It stores the image data into an appropriate SampleModel,

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.
