i just updated it, adding a couple more .png files to the help patch.
I've been trying to figure out mgraphics from your examples and from the Jgraphics stuff in the sdk, but still don't understand a few things. I want to be able to specify the colour of the text and a background colour (potentially transparent) in ol.pngknob.js but when I tried that it changed the colours of the image as well. Any ideas?
by the way the povray scripts to make the knob images can be found here:
