Points Property

Summary

Gets the list of points for the underline annotations.

Syntax

C++/CLI

Java

Python

public IList<PDFPoint> Points { get; }

public java.util.List<PDFPoint> getPoints();

public: 
property IList<PDFPoint>^ Points { 
   IList<PDFPoint>^ get(); 
}

Points # get  (PDFUnderlineAnnotation)

Property Value

An IList of PDFPoint structures that contain the list of points, in PDF units (1/72 of an inch from the bottom-left), of the underline annotations.

Remarks

The position is in PDF units (1/72 of an inch from the bottom-left). So 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.

The number of points should be multiple of four, each four points represent a single underline annotation object
