2. In Tool options:
change Position and Size drop-downs to percent (%) instead of pixels(px) (See label 1 and 2).
change Position to 0,0 to tell it to start selecting at 0 percent X and 0 percent Y (See label 3 and 4).
change Size to 50,100 to tell it to select width of 50 percent and height of 100 percent (See label 5 and 6).

Thank you very much. I believe that is a much better way than using the pixels.
