I would like to read in a JPEG image of an island with IMREAD and then
overlay a plot of shoreline datapoints with HOLD ON. I would like to be
able to adjust the shoreline so that it overlaps the JPEG, expanding the x
and y scales and offsets as necessary (I am sure someone has done
something like this already, and can tell me the best way, probably using
the mouse).

Once I have the shoreline scaled to the JPEG I plan to digitize points
on the JPEG into an array with [x,y]=GINPUT.

Thanks for your suggestions in advance! Do you have some code that will
let me scale my plot of shoreline to the JPEG of an island on which it
overlies?
