ERROR: Feature not supported. While converting pdf to image

Hi,
   I am getting Error: Feature not supported. while converting pdf to image.
I had included reference of there dlls in my Bin folder (Aspnet).
1) Leadtools.dll
2) Leadtools.Codecs.dll
3) Leadtools.Pdf.dll
4) Leadtools.Codecs.Pdf.dll
5) Leadtools.PdfEngine.dll
6) PDFTools.dll

  And here is the code i am using for conversion:

                RasterCodecs codecs = new RasterCodecs();
                string input = Path.Combine(Server.MapPath("~/Files/Uploaded/PDFs/"), SourcePdf);
                string output = Path.Combine(Server.MapPath("~/Files/Uploaded/Images/"), SourcePdf.Split('.')[0] + ".png");
                codecs.Options.Pdf.InitialPath = Server.MapPath("~/bin");
                using (RasterImage image = codecs.Load(input)) //getting error at this line
                {
                    codecs.Save(image, output, RasterImageFormat.Png, 8);
                    //codecs.Save(image, FileName, RasterImageFormat.RasPdf, image.BitsPerPixel);
                }

Am i missing something? I am using v17. Please help me. [:(]

You need to add the Leadtools.PdfEngine.dll file directly in the Bin folder. And then set the codecs.Options.Pdf.InitialPath property to the location of the Bin folder as follows:
+-----------+
RasterCodecs codecs = new RasterCodecs();

codecs.Options.Pdf.InitialPath = @"D:\WebFormsDemo\Bin";
+-----------+

If the problem persists, please create a small working project (not your full application) that shows the problem and send it to me in a ZIP or RAR file.
Also, provide me with the exact steps to reproduce the problem.

Thanks,
