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

	  NVresize.PageWidth = 5 ' page width = 5 inches
	  NVresize.PageHeight = 10 ' page height = 10 inches
	  NVresize.Units = 1 ' measurement units = inches

	  NVresize.Scale = true ' scale page
	  NVresize.ConstrainProportions = true ' constrain proportions when scaling

	  NVresize.Center = true ' center page content

	  NVresize.Linearize = true ' linearize output file

	  Dim retVal
   	  retVal = NVresize.ResizePDF("c:\in.pdf", "c:\out.pdf")
	  If retVal <> 0 Then

I was looking for a product that could place watermarks on very large PDF files (some of them over 30 thousand pages) in as less time as possible. After testing many tools I found Neevia PDFstamp. It did the job!
