Convert Method

public void Convert( 
   int firstPageNumber,
   int lastPageNumber,
   string destinationFileName
)

'Declaration
 

Public Sub Convert( _
   ByVal firstPageNumber As Integer, _
   ByVal lastPageNumber As Integer, _
   ByVal destinationFileName As String _
) 

'Usage
 

Dim instance As PDFFile
Dim firstPageNumber As Integer
Dim lastPageNumber As Integer
Dim destinationFileName As String
 
instance.Convert(firstPageNumber, lastPageNumber, destinationFileName)

public:
void Convert( 
   int firstPageNumber,
   int lastPageNumber,
   String^ destinationFileName
) 

Parameters

firstPageNumber

The 1-based number of the first page to be converted. It must be a value greater than or equal to 1.

lastPageNumber

The 1-based number of the last page to be converted. It 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".

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.

To use this method, associate the PDFFile object with a valid PDF file and optional password. Do 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 can be used to work on all or portion of the pages in a PDF file. To use all the pages of a document, pass 1 and -1 for firstPageNumber and lastPageNumber.

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

This example will convert a PDF file to 1.5 and save it with new properties.
