'Declaration
 
Public Sub Write( _
   ByVal outputFileName As String _
)

'Usage
 
Dim instance As PdfCompressorEngine
Dim outputFileName As String
 
instance.Write(outputFileName)

public void Write( 
   string outputFileName
)

 function Leadtools.PdfCompressor.PdfCompressorEngine.Write( 
   outputFileName 
)

public:
void Write( 
   String^ outputFileName
)

Parameters

outputFileName: The name of the output file to be saved.

The PDF Compressor object normally creates the compressed PDF document file in memory. It can add as many pages as required to the file. Once the PDF file in memory is complete, call this method to write the file to disk, before calling the Dispose method.
