Constructor Detail

WrappedCodec

protected WrappedCodec(ome.codecs.Codec codec)

Construct with a codec implementation to wrap.

Parameters:

codec - the codec to wrap.

Method Detail

compress

public byte[] compress(byte[] data,
                       CodecOptions options)
                throws FormatException

Description copied from interface: Codec

Compresses a block of data.

Parameters:

data - The data to be compressed.

options - Options to be used during compression, if appropriate.

Returns:

The compressed data.

Throws:

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

compress

public byte[] compress(byte[][] data,
                       CodecOptions options)
                throws FormatException

Description copied from class: BaseCodec

2D data block encoding default implementation. This method simply concatenates data[0] + data[1] + ... + data[i] into a 1D block of data, then calls the 1D version of compress.

Specified by:

compress in interface Codec

Overrides:

compress in class BaseCodec

Parameters:

data - The data to be compressed.

options - Options to be used during compression, if appropriate.

Returns:

The compressed data.

Throws:

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

decompress

public byte[] decompress(byte[] data,
                         CodecOptions options)
                  throws FormatException

Description copied from interface: Codec

Decompresses a block of data.

Specified by:

decompress in interface Codec

Overrides:

decompress in class BaseCodec

Parameters:

data - the data to be decompressed

options - Options to be used during decompression.

Returns:

the decompressed data.

Throws:

FormatException - If data is not valid.

decompress

public byte[] decompress(byte[][] data,
                         CodecOptions options)
                  throws FormatException

Description copied from class: BaseCodec

2D data block decoding default implementation. This method simply concatenates data[0] + data[1] + ... + data[i] into a 1D block of data, then calls the 1D version of decompress.

Specified by:

decompress in interface Codec

Overrides:

decompress in class BaseCodec

Parameters:

data - The data to be decompressed.

options - Options to be used during decompression.

Returns:

The decompressed data.

Throws:

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