HeightPixels Property

Summary

Gets the height of the page in pixels

Syntax

C++/CLI

Java

Python

public int HeightPixels { get; }

public int getHeightPixels();

public: 
property int HeightPixels { 
   int get(); 
}

HeightPixels # get  (PDFDocumentPage)

Property Value

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

Remarks

This value is read-only. The WidthPixels and HeightPixels are properties are populated automatically when the PDFDocument is created by using the Width and Height values in PDF units read from the file and the current resolution set in the owner PDFDocument.Resolution.

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 at a resolution of 300 corresponds to 2550 by 3300 pixels ("612 * 300"/72 by "792 * 300"/72).

You can also use the WidthInches and HeightInches to get the size of the page in inches.

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

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