All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CompressionCode>
```
public enum CompressionCode
extends java.lang.Enum<CompressionCode>
```
Compression values for generating graphics files from PDF pages. A compression value must be provided for JPG or GIF images.

Enum Constant Summary

`FLATE` Deflate algorithm (PNG only).
`G3` CCITT Group3 compression.
`G4` CCITT Group4 compression.
`LZW` Lempel-Ziv-Welch, valid for TIFF output.
`NONE` Use no image compression.

- Enum Constant Detail
  - 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).

  - values
```
public static CompressionCode[] 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 (CompressionCode c : CompressionCode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static CompressionCode valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
