Method Details

compress

public byte[] compress(byte[] data,
 loci.formats.codec.CodecOptions options)
                throws loci.formats.FormatException

Throws:

loci.formats.FormatException

compress

public byte[] compress(byte[][] data,
 loci.formats.codec.CodecOptions options)
                throws loci.formats.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 loci.formats.codec.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:

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

decompress

public byte[] decompress(byte[] data,
 loci.formats.codec.CodecOptions options)
                  throws loci.formats.FormatException

Specified by:

decompress in interface loci.formats.codec.Codec

Overrides:

decompress in class BaseCodec

Throws:

loci.formats.FormatException

decompress

public byte[] decompress(byte[][] data,
 loci.formats.codec.CodecOptions options)
                  throws loci.formats.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 loci.formats.codec.Codec

Overrides:

decompress in class BaseCodec

Parameters:

data - The data to be decompressed.

Returns:

The decompressed data.

Throws:

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

decompress

public byte[] decompress(byte[] data)
                  throws loci.formats.FormatException

Specified by:

decompress in interface loci.formats.codec.Codec

Throws:

loci.formats.FormatException

decompress

public byte[] decompress(byte[][] data)
                  throws loci.formats.FormatException

Specified by:

decompress in interface loci.formats.codec.Codec

Overrides:

Throws:

loci.formats.FormatException

decompress

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

Specified by:

decompress in interface loci.formats.codec.Codec

Specified by:

decompress in class BaseCodec

Throws:

loci.formats.FormatException

IOException

getOptions

protected static CodecOptions getOptions(loci.formats.codec.CodecOptions options)
                                  throws loci.formats.FormatException

Throws:
