Method Details

values

public static TiffCompression[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TiffCompression valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

get

public static TiffCompression get(int code)

Retrieves a TIFF compression instance by code.

Parameters:

code - Integer "code" for the TIFF compression type.

Returns:

See above.

getCode

public int getCode()

Specified by:

getCode in interface CodedEnum

getCodecName

public String getCodecName()

Retrieves the name of the TIFF compression codec.

Returns:

See above.

getCodec

public loci.formats.codec.Codec getCodec()

Returns:

the codec instance for this TIFF compression.

decompress

IOException

Decodes a strip of data.

Throws:

loci.formats.FormatException

IOException

undifference

public static void undifference(byte[] input,
