Pages Property

Summary

Object that manages the pages of the document.

Syntax

C++/CLI

Java

Python

public DocumentPages Pages { get; }

public:  
   property DocumentPages^ Pages 
   { 
      DocumentPages^ get() 
   }

public DocumentPages getPages()

Pages # get  (LEADDocument)

Property Value

The DocumentPages object that manages the pages of this LEADDocument.

Remarks

DocumentPages derives from LeadCollection<T> and thus can implement System.Collections.ObjectModel.Collection. You can use any of the collection methods to add, remove, insert, get, set and iterate through the pages.

DocumentPages contains a collection of DocumentPage that contains the data for a single page in the document. The page item is the main entry point for using the documents in a viewer or converter application. It contains functions to retrieve or update the raster or XVG image of the page, text data, annotations and hyperlinks. Refer to DocumentPage for more information.
