Syntax

C#
VB
C++
Java
public void ExtractPages( 
   int[] pages, 
   string destinationFileName 
) 
Public Sub ExtractPages( _ 
   ByVal pages() As Integer, _ 
   ByVal destinationFileName As String _ 
)  
public void extractPages( 
   int pages[],  
   java.lang.String destinationFileName 
); 
public: 
void ExtractPages(  
   int pages[], 
   String^ destinationFileName 
)  

Parameters

pages
The array of pages to be extracted. The array cannot be null and each value in the array must be greater than or equal to 1.

destinationFileName

Name of the destination PDF file to be created. If the value of this parameter is null, then the filename set in FileName will be updated.

Remarks

To use this method, associate this PDFFile object with a valid PDF file and optional password. You can achieve this by either using the PDFFile(string fileName) or PDFFile(string fileName, string password) constructors or set the filename and optional password directly into the FileName and Password properties. You do not need to call Load before using this method.

This method will use the following properties of this PDFFile object:

You can also pass the source pages as range by using the PDFFile.ExtractPages(int firstPageNumber, int lastPageNumber, string destinationFileName) method. Additionally, you can combine pages from multiple files using the PDFFile.MergeFiles or PDFFile.MergeWith methods.
