C#

using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
{
    processor.LoadDocument(@"Document.pdf");
    PdfPage page = processor.Document.Pages[0];
    page.ScaleContent(0.75,0.75);
    processor.SaveDocument("result.pdf");
}

Using processor As New PdfDocumentProcessor()
  processor.LoadDocument("Document.pdf")
  Dim page As PdfPage = processor.Document.Pages(0)
  page.ScaleContent(0.75,0.75)
  processor.SaveDocument("result.pdf")
