PDFsharp Clock

This sample shows how to create a PDF document on the fly in an ASP.NET application. For illustration the sample draws an analog clock that displays the current server time.

Here is the main routine:

private void Page_Load(object sender, System.EventArgs e)
  // Create new PDF document
  PdfDocument document  = new PdfDocument();
  this.time             = document.Info.CreationDate;
  document.Info.Title   = "PDFsharp Clock Demo";
  document.Info.Author  = "Stefan Lange";
  document.Info.Subject = "Server time: " + 
    this.time.ToString("F", CultureInfo.InvariantCulture);
  // Create new page
  PdfPage page = document.AddPage();
  page.Width  = XUnit.FromMillimeter(200);
  page.Height = XUnit.FromMillimeter(200);
  // Create graphics object and draw clock
  XGraphics gfx = XGraphics.FromPdfPage(page);
  // Send PDF to browser
  MemoryStream stream = new MemoryStream();
  document.Save(stream, false);
  Response.ContentType = "application/pdf";
  Response.AddHeader("content-length", stream.Length.ToString());

The clock looks like this (if you have Acrobat installed in your browser (click image to enlarge)):
