Method Details

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.

decompress

public byte[] decompress(loci.common.RandomAccessInputStream in,
 CodecOptions options)
                  throws FormatException,
IOException

Description copied from interface: Codec

Decompresses data from the given RandomAccessInputStream.

Specified by:

decompress in interface Codec

Specified by:

decompress in class BaseCodec

Parameters:

in - The stream from which to read compressed data.

options - Options to be used during decompression.

Returns:

The decompressed data.

Throws:

FormatException - If data is not valid compressed data for this decompressor.

IOException

decompress

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

The CodecOptions parameter should have the following fields set: maxBytes interleaved bitsPerSample littleEndian width height

Specified by:

decompress in interface Codec

Overrides:

decompress in class BaseCodec

Parameters:

buf - the data to be decompressed

options - Options to be used during decompression.

Returns:

the decompressed data.

Throws:

FormatException - If data is not valid.

• Codec.decompress(byte[], CodecOptions)

initialize

private void initialize()
                 throws FormatException

Initializes the JPEG-XR dependency service. This is called at the beginning of the decompress(loci.common.RandomAccessInputStream, loci.formats.codec.CodecOptions) method to avoid having the constructor's method definition contain a checked exception.

Throws:

FormatException - If there is an error initializing JPEG-XR services.
