Arche,

It has been a while since I used Vuescan, but, if I recall correctly, it 
allows one to make a preliminary scan, then move the four cut-off lines to 
eliminate black edges or indefinite white sky/boundary issues, and then you 
make the final scan. This would seem to set your end points as you wish to 
do.
