Syntax

C++/CLI

Java

Python

public double Height { get; set; }

public double getHeight(); 
public void setHeight( 
   double doubleValue 
);

public:

   double get(); 
   void set (    double ); 
}

Height # get and set (PDFFilePage)

Property Value

The height of the PDF page in PDF units (1/72 of an inch). The default value is 0.

Remarks

The PDFFilePage structure contains the width and height of the page in PDF units which is read from the PDF file directly. PDF page units are in 1/72 of an inch, so a page size of 612 by 792 corresponds to 8.5 by 11 inches (612/72 by 792/72).

This property returns the height of the PDF crop box. For more information, refer to PDF Coordinate System.
