Blank PDF created from DWF

I used Aspose.CAD for .NET to convert DWF to PDF.
With some DWF the pdf created is blank when page size are declared. An error opening PDF is given when AutomaticLayoutsScaling is used.
Aspose.CAD, Version=

using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(src_doc))
	Aspose.CAD.ImageOptions.CadRasterizationOptions dwfRasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();

	//dwfRasterizationOptions.PageHeight = 1200;
	//dwfRasterizationOptions.PageWidth = 1200;
	dwfRasterizationOptions.AutomaticLayoutsScaling = true;

	Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();
	pdfOptions.VectorRasterizationOptions = dwfRasterizationOptions;

	image.Save(dest_doc, pdfOptions);

I have created an issue with ID CADNET-1281 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

It is certainly a problem reading the DWF file: in Aspose.CAD.Image object, I have no Pages and negative Sizing, using my DWFs.
I attach another DWF examples.
