Hello Geotoolers,

A small postscript to my query about neighbourhood operations on grid
covereages (see below) which may be useful for other newbies.

After Martin pointed me towards JAI for doing such ops I also stumbled
upon the very handy org.geotools.image.ImageWorker class which nicely
wraps a selection of JAI operators.  I'm now happily convolving,
binarizing etc. :)
