PDF to Tiff

Hello,

I have a problem when I try to convert a PDF file into a Tiff file.

The scenario is:

I have a PDF file with XFA fields in it, I fill the XFA Fields with a XML File.

Then I flat the Generate PDF file, this flatted file looks good, with all fields and values in it.

Now I want to convert the flatted PDF file into a Tiff Image, but not all fields an values are shown in the generated Tiff image.

I've tried the fowling code in version 9.6 and 9.7 of aspose.pdf

            License lic = null;

            lic = new License();

            lic.SetLicense("Aspose.Pdf.lic");

            string pdfTemplate = @"c:\temp\in.pdf";

            string xmlData = @"C:\temp\data.xml";

            string createdPDFFile = @"c:\temp\out.pdf";

            string flatPDFFile = @"c:\temp\flat2.pdf";

            string tifFilePath = @"C:\temp\out.tiff";

            Document pdfDocument = null;

            System.IO.FileStream pdfFileStream = null;

            System.IO.FileStream xmlFileStream = null;

            Aspose.Pdf.Facades.Form form = null;

            PdfConverter pdfConverter = new PdfConverter();

            TiffSettings tiffSettings = new TiffSettings();

            Aspose.Pdf.Devices.Resolution resolution = new Aspose.Pdf.Devices.Resolution(600);

            // Fill PDF with data

            pdfFileStream = new FileStream(pdfTemplate, FileMode.Open, FileAccess.ReadWrite);

            pdfDocument = new Document(pdfFileStream);

            xmlFileStream = new FileStream(xmlData, FileMode.Open);

            form = new Aspose.Pdf.Facades.Form(pdfDocument);

            form.ImportXml(xmlFileStream);

            pdfDocument.Save(createdPDFFile);

            // Flat document

            pdfDocument = new Document(createdPDFFile);

            pdfDocument.Flatten();

            pdfDocument.Form.Type = Aspose.Pdf.InteractiveFeatures.Forms.FormType.Static;

            pdfDocument.Save(flatPDFFile);

            // Convert to tiff

            tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;

            tiffSettings.Compression = CompressionType.LZW;

            tiffSettings.Depth = ColorDepth.Format8bpp;

            tiffSettings.SkipBlankPages = false;

            pdfConverter.Resolution = resolution;

            pdfConverter.BindPdf(flatPDFFile);

            pdfConverter.DoConvert();

            pdfConverter.SaveAsTIFF(tifFilePath, PageSize.A4, tiffSettings);

I've attached my example PDF File to this entry. 

Is there something wrong with my code, or is it a bug in aspose.pdf?
