Hi Jeremias,
> Uhm, why would you want to do such a thing in an XSL-FO environment?
Because I have a table with a variable number of columns and want to implement
vertical splitting by calculating the width of all cell entries, get max width
per column and see how much I can fit on the page. The other columns move to a
new table below. Since I'm quite greedy with space, I need a result as close to
the real print result as possible. java FontMetrics is not good enough (and

Well, I do have a FopFactory. But PDFRenderer has a default constructor. So has
FontInfo. But I'm quite sure I'm thinking myself into incorrectly initialized
territory here.
I tried
FontInfo info = new FontInfo();
FontSetup.setup(info);
FontTriplet unicode = info.createFontKey("arial unicode ms",
org.apache.fop.fonts.Font.STYLE_NORMAL, org.apache.fop.fonts.Font.WEIGHT_NORMAL
);
org.apache.fop.fonts.Font funicode = info.getFontInstance(unicode, fontSize);
That gives me a nice looking FontTriplet, and the FontInfo object has internal
Fonts set, but only default fonts, no fonts from fop.xconf. Are these fonts
somewhere in PDFRenderer?

No problem, I work in pt anyway.

Betreff: Re: Usage of Font.getWordWidth()
Uhm, why would you want to do such a thing in an XSL-FO environment?
Anyway, you need access to the FontInfo object that is attached to the
PDFRenderer (somehow). If you set up the PDFRenderer yourself and set it using
FOUserAgent.setRendererOverride(), that could work. From there, you can get a
FontTriplet using FontInfo.fontLookup(). With a FontTriplet you can get a Font
object using FontInfo.getFontInstance().
The units from the Font object will most likely be millipoints (a 1000th of a
point, our internal unit). You can use UnitConv to convert those.
Sorry, I don't have a recipe ready at hand. I've never had to do something like
that from outside FOP.
