                       int y,
                       int[] dims,
                       Object options)
                throws loci.formats.FormatException

data - the data to be compressed
x - length of the x dimension of the image data, if appropriate
y - length of the y dimension of the image data, if appropriate
dims - the dimensions of the image data, if appropriate
options - options to be used during compression, if appropriate
Returns:
The compressed data
Throws:
loci.formats.FormatException - If input is not an Adobe data block.

decompress

public byte[] decompress(byte[] input,
