**Inheritance:**
java.lang.Object
```
public class PdfZoomBehavior
```

Specifies the type of zoom applied to a PDF document when it is opened in a PDF viewer.

 **Examples:** 

Shows how to set the default zooming that a reader applies when opening a rendered PDF document.

```

 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);
 builder.writeln("Hello world!");

 // Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
 // to modify how that method converts the document to .PDF.
 // Set the "ZoomBehavior" property to "PdfZoomBehavior.ZoomFactor" to get a PDF reader to
 // apply a percentage-based zoom factor when we open the document with it.
 // Set the "ZoomFactor" property to "25" to give the zoom factor a value of 25%.
 PdfSaveOptions options = new PdfSaveOptions();
 {
     options.setZoomBehavior(PdfZoomBehavior.ZOOM_FACTOR);
     options.setZoomFactor(25);
 }

 // When we open this document using a reader such as Adobe Acrobat, we will see the document scaled at 1/4 of its actual size.
 doc.save(getArtifactsDir() + "PdfSaveOptions.ZoomBehaviour.pdf", options);
 
```
