Please find the code snippet we are using below:

public static System.Drawing.Image[] ConvertPDFtoMultiPageTiff(string OutputFolder, string FullInputFileName)
{
System.Drawing.Image[] sourceImages = null;

        try
        {
           

            Document pdfDocument = new Document(FullInputFileName);
            pdfDocument.Flatten();

            //create Resolution object
            Resolution resolution = new Resolution(600);//300
            //create TiffSettings object
            TiffSettings tiffSettings = new TiffSettings();

            tiffSettings.Compression = CompressionType.CCITT4;
            tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Format8bpp;


            if (tiffSettings.Shape == ShapeType.Landscape)
                tiffSettings.Shape = ShapeType.None;
            tiffSettings.SkipBlankPages = false;
            //tiffSettings.Brightness = .40f;

            Stream output = null;
            sourceImages = new System.Drawing.Image[pdfDocument.Pages.Count];
            //create TIFF device
            TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);


            for (int page = 1; page <= pdfDocument.Pages.Count; page++)
            {
                Aspose.Pdf.ColorType pageColorType = pdfDocument.Pages[page].ColorType;
                if (pageColorType == ColorType.Rgb)
                {
                    tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;
                }

                else
                {
                    tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Format1bpp;
                }

                output = new MemoryStream();

                tiffDevice.Process(pdfDocument, page , page , output);


                sourceImages[page - 1] = System.Drawing.Image.FromStream(output);

                sourceImages[page-1].Save(Path.Combine(OutputFolder, String.Concat(Path.GetFileNameWithoutExtension(FullInputFileName), ".", page.ToString().PadLeft(3, '0'))));



            }

            output = null;
            pdfDocument = null;
            tiffSettings = null;


        }
        catch (Exception ex)
        {
            sourceImages = null;
            throw new Exception(String.Format("Error in splitTiffPages: {0}", ex.Message));
        }


        return sourceImages;
    }
