We use the PdfTron V 5.9.0 of PdfNetDotNet4 to convert PDFs to XPS using the following line:
pdftron.PDF.Convert.ToXps(pdfDoc, sOutFile, xpsOut);
This works fine and the resulting XPS-Files look fine in the Internet Explorer.
A different viewing componet we use (Silverlight application) has a problem, showing the xps-file (text is lost). This has to do with the latest Microsoft-security-patch KB2753842 (http://support.microsoft.com/kb/2507618, http://patch-info.de/artikel/2012/12/11/1463, that), that), that)), that has a problem with true-type-fonts.
I know, this is not a problem of pdftron, but we are looking for a workaround, as we don’t know, if and when Microsoft will fix this problem.
My question is, are there any options in PdfTron regarding the used fonts, that we could use, so we might avoid this problem?
A:
Apparently the problem breaks lots of programs that use these fonts, including PowerPoint:
It seems that your best bet is to complain to Microsoft. As an worst case alternative, you could convert PDF text to paths (https://groups.google.com/d/topic/pdfnet-sdk/eOATUHGFyqU/discussion). Another option could be to use some third party app to convert/normalize all PDF fonts to non-CFF TrueType font. There are some quality issues with this approach though and we are not familiar with any app that can do a good job.
