Re: Centering with proportional font

Buck...
Certainly there is a tipping point as to the effort vs. reward. But, the
printed document is what the customer sees and aesthetics should not be
underestimated. 1/10"? Probably OK. 3/4"? Likely not OK. When I did
the PCL stuff, we needed to right justify some things. Could get it
accurate to the dot level.

Vern...
I had a vague recollection of an API that would retrieve the font widths
also.

PAGSEG may be doable. Only about 6 offices to deal with and I could put a
reference in the Office Master table. The gist of things is to soft code
what is now all hard coded and is an issue due to expansion.

One hurdle would be that a given print run (invoices, etc) encompasses
multiple (or all) offices.

Thanks for the suggestions. Need to read up on PAGSEG.

I thought there were some kind of width tables on the i - vague memory of
digging around once.

I've done this years ago with HP fonts by building a width table and

using
absolute positioning with PCL.

That's going to be quite precise. Does your office name need to be centred
to a tenth of an inch? Sometimes it helps to nail down how much effort to
expend...

I've not used AFP much except for drawing forms. How do you deal with

variable or relative text postioning this using AFP and proportional fonts?

A first approximation is to divide the length in half and position that way
via POSITION(). Some names will be more skewed than others. If that's not
good enough, you can always go the route of building a custom width table
and doing that calculation. But with AFP there's a third
way: Make the office name an image file as wide as the paper. Centre the
name within the image and print it at position 1 via PAGSEG. Be advised
that PAGSEG won't rotate, so if the page is rotated you'll need a rotated
image.
