Class TIFFDecoderPackbits
public class TIFFDecoderPackbits
A TIFF decoder for files compressed with the Packbits method.
This compression algorithm has the value 32773
in the compression tag of an image file directory.

decode
public void decode()
throws InvalidFileStructureException,
IOException Decode data from input and write the decompressed pixel data to
the image associated with this decoder.
Child classes must override this method to implement the decoding
for a particular compression type.

getCompressionTypes
public Integer[] getCompressionTypes()
Returns an array with Integer values of all compression types supported by
this decoder (see the COMPRESSION_xyz constants in
TIFFConstants.
Normally, this is only one value, but some compression types got assigned more than one constant
(e.g. deflated).
Also, a decoder could be capable of dealing with more than one type of compression
if the compression types are similar enough to justify that.
However, typically a decoder can only deal with one type of compression.
