@AStelzner,

Hi,

ok, i want to convert several Powerpoint to PDF in parallel threads (same process) and get some confusing Exceptions:
InvalidCastException, Das Objekt des Typs “System.Drawing.SolidBrush” kann nicht in Typ “System.Drawing.TextureBrush” umgewandelt werden.
OR
ArgumentException, Ungültiger Parameter.

If i convert the same files synchron, no error happens!
Is there a special way or “best practice” how to convert Slides parallel?

Kind Regards,
Andy

@AStelzner,

I have observed your question and like to share that Aspose.Slides is a thread safe library and does support multi-threaded application. In order to reproduce the issue further on our end, I need to have a sample Visual Studio project along with source files reproducing the issue. I am also assuming that you are using latest Aspose.Slides for .NET 20.5 on your end.
