Hi Wayne, I tried your issue with GdGetTextSize() and get a result. I compared the widths I get from GrGetTextSize() and GrGetFontInfo() => different widths.
For my problem: I use both functions in combinition to get the info I need. Many thanks. But only for interest: Why is it so? merry christmas and a happy new year 2014 Andreas -----Ursprüngliche Nachricht----- Von: Wayne Johnson [mailto:wa...@zk.com] Gesendet: Donnerstag, 19.

We don't use that portion of the code so I don't have it in my source tree at the moment. I would look for this function in the nano-x wrapper code to see if it used. From there you can figure out how it is exposed.
