PDPage (Apache PDFBox 1.8.10 API)

java.lang.Object
- org.apache.pdfbox.pdmodel.PDPage

All Implemented Interfaces:

Printable, COSObjectable
```
public class PDPage
extends Object
implements COSObjectable, Printable
```
This represents a single page in a PDF document.
This class implements the Printable interface, but since PDFBox version 1.3.0 you should be using the PDPageable adapter instead (see PDFBOX-788).
