Center Property

Summary

Center point of this ellipse annotation.

Syntax

C++/CLI

Java

Python

public PDFPoint Center { get; set; }

public PDFPoint getCenter(); 
public void setCenter( 
   PDFPoint pDFPoint 
);

public: 
property PDFPoint Center { 
   PDFPoint get(); 
   void set (    PDFPoint ); 
}

Center # get and set (PDFEllipseAnnotation)

Property Value

A PDFPoint that represents the center point, in PDF units (1/72 of an inch from the bottom-left), of the ellipse annotation. The default value is an empty PDFPoint.

Remarks

The position is in PDF units (1/72 of an inch from the bottom-left). To go to the top of the page, you must go to "0, PageHeight". You can use the PDFDocumentPage.ConvertPoint helper method to convert from pixel or inches to PDF units and back.
