Convert from VSDX to PDF using Aspose.Diagram for .NET - cut in the final PDF

Hello
I used Aspose.Diagram.dll in .Net solution to convert file from vsdx to pdf and it was done successfully.

My question is: Why do I have a cut in the final PDF (white horizontal lines)?
How to get the pdf file with the highest resolution?
Why do Arabic words appear in the opposite direction?

I attached two pdf files, one created by aspose.diagram, and the other original, to see what i mean (white horizontal lines)

With Regards
