Enum Constant Detail

• Auto

  public static final PdfImageCompression Auto

  Automatically selects the most appropriate compression for each image.

• None

  public static final PdfImageCompression None

  Saves raw image bytes resulting in bigger PDF file sizes.

• Rle

  public static final PdfImageCompression Rle

  Run Length compression.

• Flate

  public static final PdfImageCompression Flate

  Flate compression.

• LzwBaselinePredictor

  public static final PdfImageCompression 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 PdfImageCompression LzwOptimizedPredictor

  Predictor selection is more complicated and should result in smaller image sizes but taking more time.

• Jpeg

  public static final PdfImageCompression Jpeg

  JPEG compression. Does not support transparency.

Method Detail

• values

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

  Returns:

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

• valueOf

  public static PdfImageCompression 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
