Re: link areas within images

I've just played with Xerox PARCs world map, and been following the
discussion of hot spots with images, and arbitrary polygon hotspots.

It occurs to me to ask whether the various mechanisms described can
handle sending an arbitrary region of the image, e.g. could my broswer
permit me to draw an outline of the region (e.g. Europe on the world
map) I want, then send back a URL for map?X1,Y1+X2,Y2.

This seems to be a reasonable requirement, but I haven't seen it
explictly describe in the correspondence so far.
