Syntax

C#
VB
C++
public void InsertPagesFrom( 
   int insertPageNumber, 
   PDFFile sourceFile, 
   int firstPageNumber, 
   int lastPageNumber 
) 
Public Sub InsertPagesFrom( _ 
   ByVal insertPageNumber As Integer, _ 
   ByVal sourceFile As Leadtools.Pdf.PDFFile, _ 
   ByVal firstPageNumber As Integer, _ 
   ByVal lastPageNumber As Integer _ 
)  
public: 
void InsertPagesFrom(  
   int insertPageNumber, 
   Leadtools.Pdf.PDFFile^ sourceFile, 
   int firstPageNumber, 
   int lastPageNumber 
)  

Parameters

insertPageNumber
The 1-based number of the insertion point in this PDFFile object. Use a value of 0 to insert the new pages at the beginning of the file and -1 to insert the new pages at the end of the file (append).

sourceFile
A PDFFile object associated with an existing PDF file that contain the source file to insert the pages from.

firstPageNumber
The 1-based number of the first page in the source file to be inserted. Must be a value greater than or equal to 1.

lastPageNumber
The 1-based number of the last page in the source file to be inserted. Must be a value greater than or equal to firstPageNumber and less than or equal to the total number of pages in the file. Use the special value of -1 to represent "last page in the file".

Remarks

Both files in this PDFFile (the destination) and sourceFile must exist and contain valid PDF files prior to calling this method.

To use this method, associate this PDFFile object and the source PDFFile 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:

  • DocumentProperties. If the value of this property is null, then default properties will be used

  • SecurityOptions. If the value of this property is not null, then the destination file will be encrypted using the properties of this property. If the value of this property is null, the result file will not be encrypted

  • CompatibilityLevel. The version of the generated PDF file

Example

This example will insert pages from an existing PDF file to a different one in various locations.
