Re: Printing double underline

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Yep.  I feel your pain, Mark. It's very hard to get any sort of text 
metrics (font width, height, string length, etc.) when working with 
printing on the i.

With CPI/LPI, I tend to just hard-code it.  That means that if I change 
my print file, I'll have to modify my program as well...  ugly, I know, 
but it's what I do.

What's even worse is when using fonts in AFP.  I don't mean the 
fixed-width LPI/CPI fonts, but rather the proportional ones. There's 
absolutely way to get font metrics about height and width.  On other 
platforms there are extensive libraries of routines to give you 
information about this sort of thing, but on i you're pretty much S.O.L. 
unless you can hard-code the positions of everything.
