Copy the PDFcompress .NET assembly from the c:\program files\neeviaPDF.com\PDFcompress\ dotNet\ folder into your web site bin folder;

	  NVcomp.CI = "jpx"
	  NVcomp.CQ = 20

	  NVcomp.GI = "jpx"
	  NVcomp.GQ = 20

	  NVcomp.MI = "jbig2"
	  NVcomp.MQ = 2

	  ' For better compression uncomment the line below
	  ' NVcomp.CreateObjectStreams = true

   	  retVal = NVcomp.CompressPDF("c:\in.pdf", "c:\out.pdf")
	  If retVal <> 0 Then
  	    Response.Write("Error code=" & CStr(retVal))
