Class RawImageReader

  • public class RawImageReader
extends javax.imageio.ImageReader
    This class is the Java Image IO plugin reader for Raw images. It may subsample the image, clip the image, select sub-bands, and shift the decoded image origin if the proper decoding parameter are set in the provided PNMImageReadParam.
