Write In Existing Pdf Using ItextSharp on Specific Coordinat

Hello,

Here is my code to draw rectangle in existing PDF document. But I don't use itextpdf but another .NET PDF component.

  PdfDocument document = new PdfDocument();
  document.LoadFromFile("Sample");
  PdfPageBase page = document.Pages[0];
  //save graphics state
  PdfGraphicsState state = page.Canvas.Save();
  //draw rectangles
  PdfPen pen = new PdfPen(Color.ForestGreen, 0.1f);
  PdfPen pen1 = new PdfPen(Color.Red, 3f);
  PdfBrush brush = new PdfSolidBrush(Color.Orange);
  page.Canvas.DrawRectangle(pen, new Rectangle(new Point(10, 350), new Size(120, 120)));
  page.Canvas.DrawRectangle(pen1, new Rectangle(new Point(350, 350), new Size(160, 120)));
  page.Canvas.DrawRectangle(brush, new RectangleF(new Point(158, 350), new SizeF(160, 120)));
  //restor graphics
  page.Canvas.Restore(state);
