Why does this work:
Infragistics.Documents.Graphics.Font QuoteFonta = new Infragistics.Documents.Graphics.Font("verdana", 16, "C:\\Windows\\Fonts\\verdana.ttf");
But this does not work:
(Open Type Font)
Infragistics.Documents.Graphics.Font QuoteFonta = new Infragistics.Documents.Graphics.Font("MyriadPro-Black", 16, "C:\\Windows\\Fonts\\MyriadPro-Black.otf");
Both fonts are in the directory indicated.
I'm not sure, but I know there are some limitations to the way PDF files deal with fonts. You should submit your question to Infragistics developer support so they can check it out and give you a more definitive answer. Submit an incident to Infragistics Developer Support
