Remarks

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. You must call RasterCodecs.StartUp before using this function.
