To subset using map coordinates, you first need to convert your map
coordinates into pixel coordinates for the image of interest. Create
an array containing the lat/lon coordinates for a box containing Italy
(or whatever map subset you want), and push these through
ENVI_CONVERT_FILE_COORDINATES to retrieve their respective pixel
coordinates. Then construct your DIMS vector to RESIZE_DOIT by
finding the min and max boundaries of the returned vertices (in pixel
coordinates) that form a polygon.
