Summary

Gets the height of the page in inches.

Syntax

C++/CLI

Java

Python

public double HeightInches { get; }

public double getHeightInches();

public: 
property double HeightInches { 
   double get(); 
}

HeightInches # get  (PDFDocumentPage)

Property Value

The height of the page in inches. The default value is 0.

Remarks

This value is read-only. The WidthInches and HeightInches are properties are populated automatically when the PDFDocument is created by dividing the Width and Height values read from PDF file by 72.

This value is the height of crop box of this page stored in CropBox, For more information, refer to PDF Coordinate System.

PDF units are in 1/72 of an inch, so a page size (Width and Height) of 612 by 792 corresponds to 8.5 by 11 inches (612/72 by 792/72).

You can also use the WidthPixels and HeightPixels to get the size in pixels (depending on the current resolution set in the owner PDFDocument.Resolution.

The PDFDocumentPage object also contains the ConvertPoint and ConvertRect helper methods that can be used to convert a point or a rectangle to and from page/object to pixel or inch coordinates.

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