		Hi!

	

		I am having some trouble with the rendered PDF.  If i use a Windows Server 2008 with IE9 all works great, but on Server 2003 with IE 7 the text and images are rendered with really bad quality.

	

		Are this a know issue?

	

		 

	

		I am using the following code to render the PDF.

	

		 

	
    
		
  1. 
			//Create a PDF document 
    2. 
		
  2. 
			PdfDocument doc = new PdfDocument(PdfDocumentConformanceLevel.None);
    3. 
		
  3. 
			 
    4. 
		
  4. 
			PdfUnitConvertor convertor = new PdfUnitConvertor();
    5. 
		
  5. 
			doc.PageSettings.SetMargins(15, 30, 15, 40);
    6. 
		
  6. 
			doc.PageSettings.Orientation = PdfPageOrientation.Portrait;
    7. 
		
  7. 
			doc.PageSettings.Rotate = PdfPageRotateAngle.RotateAngle0;
    8. 
		
  8. 
			doc.PageSettings.Size = PdfPageSize.A4;
    9. 
		
  9. 
			 
    10. 
		
  10. 
			PdfMetafileLayoutSettings format = new PdfMetafileLayoutSettings();
    11. 
		
  11. 
			format.Layout = PdfLayoutType.Paginate;
    12. 
		
  12. 
			format.Break = PdfLayoutBreakType.FitElement;
    13. 
		
  13. 
			format.SplitTextLines = false;
    14. 
		
  14. 
			format.SplitImages = false;
    15. 
		
  15. 
			 
    16. 
		
  16. 
			PdfPage newPage = doc.Pages.Add();
    17. 
		
  17. 
			float width = -1;
    18. 
		
  18. 
			float height = -1;
    19. 
		
  19. 
			AspectRatio dimension = AspectRatio.KeepWidth;
    20. 
		
  20. 
			height = convertor.ConvertToPixels(newPage.GetClientSize().Height, PdfGraphicsUnit.Point);
    21. 
		
  21. 
			width = convertor.ConvertToPixels(newPage.GetClientSize().Width, PdfGraphicsUnit.Point);
    22. 
		
  22. 
			 
    23. 
		
  23. 
			Html2PdfOptions options = new Html2PdfOptions();
    24. 
		
  24. 
			options.EnableJavaScript = true;
    25. 
		
  25. 
			options.AutoDetectPageBreak = false;
    26. 
		
  26. 
			options.EnableHyperlinks = false;
    27. 
		
  27. 
			options.Width = (int)width;
    28. 
		
  28. 
			options.Height = (int)height;
    29. 
		
  29. 
			options.SplitTextLines = true;
    30. 
		
  30. 
			options.AspectRatio = dimension;
    31. 
		
  31. 
			 
    32. 
		
  32. 
			var url = "testpage.aspx";
    33. 
		
  33. 
			var sb = new StringBuilder();
    34. 
		
  34. 
			var writer = new StringWriter(sb);
    35. 
		
  35. 
			HttpContext.Current.Server.Execute(url, writer, false);
    36. 
		
  36. 
			var html = sb.ToString().Replace("charset=utf-8", "");
    37. 
		
  37. 
			doc.ImportHtmlText(html, options);
    38. 
		
  38. 
			// Rendering HtmlText 
    39. 
		
  39. 
			doc.Save(finalFilename)
    40. 
		
  40. 
			doc.Close();  
    41.
