[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]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. Jim Nichols Tullahoma, TN USA ----- Original Message ----- From: "H.
