TIFFDecompressorbyte
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.
decodeRaw in class TIFFDecompressorb - 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.
IOException - if an error occurs reading from the source
ImageInputStream.
