Class TIFFFaxDecompressor

    • Field Detail

      • fillOrder

        protected int fillOrder
        The logical order of bits within a byte.
         1 = MSB-to-LSB
         2 = LSB-to-MSB (flipped)
         
      • compression

        protected int compression
      • uncompressedMode

        protected int uncompressedMode
        Uncompressed mode flag: 1 if uncompressed, 0 if not.
      • fillBits

        protected int fillBits
        EOL padding flag: 1 if fill bits have been added before an EOL such that the EOL ends on a byte boundary, 0 otherwise.
      • oneD

        protected int oneD
        Coding dimensionality: 1 for 2-dimensional, 0 for 1-dimensional.

    • Method Detail

      • beginDecoding

        public void beginDecoding()
        Invokes the superclass method and then sets instance variables on the basis of the metadata set on this decompressor.
        Overrides:
        beginDecoding in class TIFFDecompressor
      • decodeRaw

        public void decodeRaw​(byte[] b,
                              int dstOffset,
                              int pixelBitStride,
                              int scanlineStride)
                       throws IOException
        Description copied from class: TIFFDecompressor
        Decodes the source data into the provided byte array b, starting at the offset given by dstOffset. Each pixel occupies bitsPerPixel bits, with no padding between pixels. Scanlines are separated by scanlineStride bytes.
        Specified by:
        decodeRaw in class TIFFDecompressor
        Parameters:
        b - a byte array to be written.
        dstOffset - the starting offset in b to be written.
        pixelBitStride - the number of bits for each pixel.
        scanlineStride - the number of bytes to advance between that starting pixels of each scanline.
        Throws:
        IOException - if an error occurs reading from the source ImageInputStream.
