public enum CompressionValue
extends Enum<CompressionValue>

Enumerates the possible compression values for TIFF images.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DEFLATE	DEFLATE lossless compression (also known as "Zip-in-TIFF").
GROUP3_1D	Modified Huffman Compression (CCITT Group 3 1D facsimile compression).
GROUP3_2D	CCITT T.4 bilevel compression (CCITT Group 3 2D facsimile compression).
GROUP4	CCITT T.6 bilevel compression (CCITT Group 4 facsimile compression).
JPEG_BROKEN	Code for original JPEG-in-TIFF compression which has been depricated (for many good reasons) in favor of Tech Note 2 JPEG compression (compression scheme 7).
JPEG_TTN2	JPEG-in-TIFF compression.
LZW	LZW compression.
NONE	No compression.
PACKBITS	Byte-oriented run-length encoding "PackBits" compression.

Method Summary

Modifier and Type	Method	Description

Method Detail

values

public static CompressionValue[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CompressionValue c : CompressionValue.values())
    System.out.println(c);

Returns:

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

valueOf

public static CompressionValue 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

getValue

public static CompressionValue getValue(String name)

Gets the compression value given the name of the compression type.

Parameters:

name - the compression name

Returns:

the compression value
