Enum Constant Detail

• Auto

  public static final ImageCompressionEnum Auto

  Automatically selects the most appropriate compression for each image.

• None

  public static final ImageCompressionEnum None

  Saves raw image bytes resulting in bigger pdf file sizes.

• Rle

  public static final ImageCompressionEnum Rle

  Run Length compression.

• Flate

  public static final ImageCompressionEnum Flate

  Flate compression.

• LzwBaselinePredictor

  public static final ImageCompressionEnum LzwBaselinePredictor

  Predictor selection is restricted to PNG Paeth predictor to speed-up the process. In practice performs surprisingly good. Better than LzwOptimizedPredictor.

• LzwOptimizedPredictor

  public static final ImageCompressionEnum LzwOptimizedPredictor

  Predictor selection is more complicated and should result in smaller image sizes but taking more time. RFC 2083 says it is the best way to go. But on the test data baseline predictor LzwBaselinePredictor kicks ass leaving optimized predictor behing by 25-40% compression rate gains.

• Jpeg

  public static final ImageCompressionEnum Jpeg

  Jpeg compression. Does not support transparency.

• Ccitt3

  public static final ImageCompressionEnum Ccitt3

  /CCITTFaxDecode/DecodeParms/K 0/Columns 173 Does not support transparency.

• Ccitt4

  public static final ImageCompressionEnum Ccitt4

  /CCITTFaxDecode/DecodeParms/K -1/Columns 173 Does not support transparency.

Method Detail

• values

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

  Returns:

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

• valueOf

  public static ImageCompressionEnum 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

• getType

  public int getType()

  Gets the value that represents the type of the enum.

  Returns:

  the type
