PDF to Tiff conversion error Null reference exception


with the pdf attached to this post I receive this error:

System.NullReferenceException: Riferimento a un oggetto non impostato su un’istanza di oggetto.
in .?.?()
in .?.()
in Aspose.Pdf.PageCollection…ctor(Document )
in Aspose.Pdf.Document.()
in Aspose.Pdf.Document.(String , String )
in Aspose.Pdf.Document…ctor(String filename)

with this code:

Aspose.Pdf.Document oDoc = new Aspose.Pdf.Document(sFile);
Aspose.Pdf.Devices.Resolution resolution = new Aspose.Pdf.Devices.Resolution(200);

Aspose.Pdf.Devices.TiffSettings tiffSettings = new Aspose.Pdf.Devices.TiffSettings();

tiffSettings.Compression = Aspose.Pdf.Devices.CompressionType.LZW;

tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;
tiffSettings.Shape = Aspose.Pdf.Devices.ShapeType.Portait;
tiffSettings.SkipBlankPages = false;

Aspose.Pdf.Devices.TiffDevice tiffDevice = new Aspose.Pdf.Devices.TiffDevice(resolution, tiffSettings);

tiffDevice.Process(oDoc, sFile + “.tif”);

I have tried also with the latest version 6.4.2

Can you help me?

Thank you.
