- de.intarsys.pdf.encoding.Encoding
- - de.intarsys.pdf.font.DifferenceEncoding

```
public class DifferenceEncoding
extends Encoding
```
An encoding defined as a delta to another base encoding.
```
   the encoding difference is defined in the form
   ...
   num name name name
   num name..
   ...
 
```
where num is the codepoint for the first glyph name in the list. The following names are mapped to the codepoint of the predecessor + 1. Multiple redefinition offsets can be defined.
