    • decodeRaw

      public void decodeRaw(byte[] b, int dstOffset, int bitsPerPixel, 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.
      bitsPerPixel - 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.
