    The default implementation computes tables used by the decode method to rescale components to different bit depths. Thus, if this method is overridden, it is important for the subclass method to call super(), unless it overrides decode as well.
    
    Overrides:
    
    beginDecoding in class TIFFDecompressor
  - decodeRaw

               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:
    buf - 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.
