Tim, you might want to test the PDF transcoder that is bundled with Apache Batik. Or to get the latest version of the PDF transcoder, just put the latest Apache FOP in the classpath instead of pdf-transcoder.jar. That has the benefit that you don't have to care much about the scaling problem and you get text as text (and not text converted to shapes) and nice-looking gradients among other things.
