Enum Constant Details

DEFAULT

public static final CompressionCode DEFAULT

Use the default for the output image type.

NONE

public static final CompressionCode NONE

Use no image compression. Valid for BMP, PNG and TIFF outputs only.

FLATE

public static final CompressionCode FLATE

Deflate algorithm (PNG only). An open source standard widely used for creating zip files and with PDF.

LZW

public static final CompressionCode LZW

Lempel-Ziv-Welch, valid for TIFF output. Valid for GIF and TIFF. A lossless algorithm, resulting files are larger but retain original quality.

G3

public static final CompressionCode G3

CCITT Group3 compression. Valid for TIFF, requires colorModel gray. A lossless algorithm for black and white images that efficiently compresses whitespace.

G4

public static final CompressionCode G4

CCITT Group4 compression. Valid for TIFF, requires colorModel gray. A lossless algorithm for black and white images based on G3.

DCT

public static final CompressionCode DCT

Discrete Cosine Transform. Lossy algorithm, valid for JPEG. Best when used with continuous tone (such as photographs).

Method Details

values

public static CompressionCode[] values()

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

Returns:

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

valueOf

public static CompressionCode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
