rpfProps.put("rpfLayer.imageScaleFactor", "32");
Got it. Worked great. I did see that in the javadoc for rpfLayer, but frankly if you're not an expert on OpenMap nor familiar with RPF, many of the properties need more than a single-line comment to understand what is going on. and I wasn't about to mess around with the defaults until I got it working...
So thanks again :-)

You can increase the scaleFactor property.
