In direct graphics I use textoidl and Hershey fonts
for dealing with greek characters, subscripts and superscripts.
What is the best way to deal with that in object graphics?
I'm under the impression that in OG I have to declare a font,
for example Hershey 4 and use it for a text object. But how
do I mix different Hershey fonts?
thanks,
Mirko

The little snippet of code I tried mixed succesfully roman and greek
Hershey fonts.
Makes me very happy.
Thanks a lot guys.

Well there's the enable_formatting keyword to IDLgrText::Init:
ENABLE_FORMATTING (Get, Set)
Set this keyword to indicate that the text object should honor
embedded Hershey-style formatting codes within the strings.
(Formatting codes are described in Fonts.) The default is not
to honor the formatting codes.
I know that this causes positioning codes like !E and !N to be recognised
(with TrueType as well as Hershey Fonts). I've never tried the codes to
select different fonts.

As the good folks at RSI have let me know, this *would*
have worked had a just set the ENABLE_FORMATTING keyword
on the text object.
So, to do this: use a Font object set up to use Hershey
fonts and be sure you enable embedded formatting codes
by setting the ENABLE_FORMATTING keyword on the text object.
Cheers,
David

Humm, well, *that's* a good question. You certainly can't
use the normal Hershey escape characters, as I just found
out to my chagrin. :-(
I'll see what I can find out, but in the meantime, let
us know if you learn something, Mirko.
Cheers,
David
