  i am convert a image to pdf using pdfsharp lib. i need to set margin & page size so i got a trick from this forum to set page size and margin. from here i got code which i used but getting error for two area. here is code which i got.

  page = document.AddPage();
  //page.Size = PdfSharp.PageSize.A4;
  XSize size = PageSizeConverter.ToSize(PdfSharp.PageSize.A4);
  if(page.Orientation == PageOrientation.Landscape)
  {
     page.Width  = size.Height;
     page.Height = size.Width;
  }
  else
  {
     page.Width  = size.Width;
     page.Height = size.Height;
  }
  
  // default unit in points 1 inch = 72 points
  page.TrimMargins.Top = 5;
  page.TrimMargins.Right = 5;
  page.TrimMargins.Bottom = 5;
  page.TrimMargins.Left = 5;

  i got a error for this line

  XSize size = PageSizeConverter.ToSize(PdfSharp.PageSize.A4);

  so i need to change it to

  System.Drawing.Size size = PageSizeConverter.ToSize(PdfSharp.PageSize.A4);

  now my program compile but when i set margin then i am getting error called PdfSharp does not contain a definition for TrimMargins

  these below line does not compile for setting margin.

      pdfPage.TrimMargins.Top = 5;
      pdfPage.TrimMargins.Right = 5;
      pdfPage.TrimMargins.Bottom = 5;
      pdfPage.TrimMargins.Left = 5;
