public void setStream(ImageOutputStream stream)
TIFFCompressorImageOutputStream to be written.
setStream in class TIFFCompressorstream - an ImageOutputStream to be written.TIFFCompressor.getStream()
public int encode(byte[] b,
int off,
int width,

throws IOException
TIFFCompressorImageOutputStream.
encode in class TIFFCompressorb - an array of bytes containing the packed
but uncompressed image data.off - the starting offset of the data to be written in the
array b.width - the width of the rectangle of pixels to be written.height - the height of the rectangle of pixels to be written.bitsPerSample - an array of ints indicting
the number of bits used to represent each image sample within
a pixel.scanlineStride - the number of bytes separating each
row of the input data.
IOException - if the supplied data cannot be encoded by
this TIFFCompressor, or if any I/O error occurs
during writing.
