Java text handling
Do any of the list denizens have experience with Java font handling and
2D text layout? I'm new to it, and would like to be able to bounce
questions off someone further up the food chain, on or off-line.

I'll have a look at it, thanks.

In no way. While Luca seems to have reimplemented the glue/box/penalty
model, I have a generalization/simplification. I think it is similar to
what Knuth mentions in the Addendum in Digital Typography, Breaking
Paragraphs into Lines, as socalled kerfs model. In UTA there are only
Items. A break is allowed behind every item, an item has a penalty and
different widths depending on its position.

There might be a problem: UTA uses JGraphT which is LGPL. FOP cannot
depend on LGPL software (Apache licence policy).
There is a "graph" subproject inside Jakarta Commons. Maybe this could
be used instead of JGraphT.
Anyway, how does UTA relate to Luca's recent patch on line breaking?

The typesetting is done Font.layoutGlyphVector and
java.awt.font.GlyphVector.performDefaultLayout. Currently TrueType is
supported and therefore the philosophy 'do everything within the font'.
This makes the Java API very hard to extend and not very modular. Cause
OpenType follows the philosophy 'do as much of the typesetting within
the application' it's hard to support both the same time. There are
typesetting issues which are font dependent and some which are not.
My advice: Use UTA and provide a wrapper around the Java font class in
form of a Script [1]. ;-)

My experience has more to do with JRE and FONT handling, rather than
what you probably want. Suffice it to say, that when you're doing
testing use either IBM JRE 1.3.x+ or Sun JRE 1.4.0_b09+ as the AWT
component of earlier versions have significant, sporadic font kerning
issues. PDF/Postscript appears to be OK, though.
