This probably isn't the right forum, but I've looked everywhere and can't figure this out on my own or with Google's help.
I was on a Windows machine, using Oxygen 16.1 and the Apache FOP for PDF output. My fonts used Avenir Light and Medium. No problems. I switched to a Mac OS X Yosemite, and the Avenir set is included as a .ttc. Even though I've installed the OTF fonts, when I generate the PDF my system uses Avenir fonts that it chooses. It chooses Book and Heavy, which is not what I want.
Finally, to the question. How do I get the FOP to let me select which fonts within the .ttc to use? I didn't see anything in fop.xconf that looked like I could do that. Can anyone point me in the right direction? Please and thank you.
