Hi Rakshit and thanks Michael for putting me in the loop.
Actually Jody wrote the font part for the uDig project, I just did the
job in pasting and adapting it here :)
Have a look at the org.geotools.swt.styling.simple.LabelViewer class.
Everything you need happens inside the method:
public TextSymbolizer get( StyleBuilder build )
Cheers,
Andrea
