Summary

Syntax

C++/CLI

Java

Python

public int TargetZoomPercent { get; set; }

public int getTargetZoomPercent(); 
public void setTargetZoomPercent( 
   int intValue 
);

public: 
property int TargetZoomPercent { 
   int get(); 
   void set (    int ); 
}

TargetZoomPercent # get and set (PDFInternalLink)

Property Value

A System.Int32 that specifies the zoom percent (100 equals to no zoom) of the target page. The default value is 0.

Remarks

The zoom percent (100 equals to no zoom) of the target page. External viewers should zoom to this value when the internal link is activated. A value of 0 means do not change the current zoom percentage when going to the target page.
