All Implemented Interfaces:

Serializable, Comparable<CompressionMethod>

public enum CompressionMethod
extends Enum<CompressionMethod>

Defines the compression method used for image data.

Enum Constant Summary

Enum Constants

Enum Constant and Description
Raw No compression.
RLE RLE compressed the image data starts with the byte counts for all the scan lines (rows * channels), with each count stored as a two-byte value.
ZipWithoutPrediction ZIP without prediction.
ZipWithPrediction ZIP with prediction.

Enum Constant Detail

Raw

public static final CompressionMethod Raw

No compression. The image data stored as raw bytes in RGBA planar order. That means that first all R data is written, then all G is written, then all B and finally all A data is written.

RLE

public static final CompressionMethod RLE

RLE compressed the image data starts with the byte counts for all the scan lines (rows * channels), with each count stored as a two-byte value. The RLE compressed data follows, with each scan line compressed separately. The RLE compression is the same compression algorithm used by the Macintosh ROM routine PackBits and the TIFF standard.

ZipWithoutPrediction

public static final CompressionMethod ZipWithoutPrediction

ZIP without prediction.

ZipWithPrediction

public static final CompressionMethod ZipWithPrediction

ZIP with prediction.

Method Detail

values

public static CompressionMethod[] 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 (CompressionMethod c : CompressionMethod.values())
    System.out.println(c);

Returns:

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

valueOf

public static CompressionMethod 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
