Peter, I've had a look at your changes to the RTF output concerning image support. It's cool to see that switching to FOP's image adapters was relatively painless.
I've stumbled upon one problem, though. If you run external-graphic_emf.xml through the RTFHandler the image is distorted. It looks like RtfExternalGraphic.computeImageSize() fetches wrong values from the EMF. That's not so important for me right now, but I wanted you to know about it. Jeremias Maerki
