Method Detail

compress

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

Encodes a block of data into Base64.

Specified by:

compress in interface Codec

Parameters:

input - the data to be encoded.

x - ignored.

y - ignored.

dims - ignored.

options - ignored.

Returns:

The encoded data.

Throws:

loci.formats.FormatException - If input is not a compressed data block of the appropriate type.

decompress

public byte[] decompress(byte[] base64Data,
                         Object options)
                  throws loci.formats.FormatException

Decompresses a block of data.

Specified by:

decompress in interface Codec

Parameters:

base64Data - the data to be decoded

options - Options to be used during decompression.

Returns:

The decoded data

Throws:

loci.formats.FormatException - if data is not valid Base64 data

base64Decode

public byte[] base64Decode(String s)
                    throws loci.formats.FormatException

Decodes a Base64 String by converting to bytes and passing to the decompress method.

Parameters:

s - the String to be decoded

Returns:

The decoded data

Throws:

loci.formats.FormatException - if s is not valid Base64 data.

main

public static void main(String[] args)
                 throws loci.formats.FormatException

Main testing method. test is inherited from parent class.

Parameters:

args - ignored

Throws:

loci.formats.FormatException - Can only occur if there is a bug in the compress method.
