Method Detail

compress

public byte[] compress(byte[] data,
                       int x,
                       int y,
                       int[] dims,
                       Object options)
                throws loci.formats.FormatException

Compresses a block of Nikon data. Currently not supported.

Specified by:

compress in interface Codec

Parameters:

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,
                         Object options)
                  throws loci.formats.FormatException

Decodes an image strip using Nikon's compression algorithm (a variant on Huffman coding). TODO : this is broken

Specified by:

decompress in interface Codec

Parameters:

input - input data to be decompressed

options - Options to be used during decompression.

Returns:

The decompressed data

Throws:

loci.formats.FormatException - if data is not valid compressed data for this decompressor
