If this is not even close to what you want, then perhaps you need to upgrade your IM. I used 6.5.8-10 Q16 Mac OSX Tiger.

the 100x65000 was some trial and error as I have not used vignette much. using x65000 means that the taper will be linear rather than gaussian. the 100 means that the taper should extend over about 100 pixels.
