```
    Returns the bitrate reduction (compression information). This will be an array of seven strings (which may be empty, but should never be null) interpreted as follows:
    
    0: codecName
    1: codecNameVersion

public void setUse(String useType,
                   String otherType)
```
    Sets the role of the document. Permitted values are ORIGINAL_MASTER, PRESERVATION_MASTER, PRODUCTION_MASTER, SERVICE, PREVIEW, or OTHER. If useType is "OTHER", then otherType is significant. Since OTHER is the only meaningful value for a digital document, the code assumes this will always be the case and uses otherType.

public void setWordSize(int wordSize)
```
    Sets the word size.
  - addFormatRegion
```
public void addFormatRegion()
```

public void addFace()
```
    Adds a Face.
