In the example below, the white box is the centering window. The centering window has been
set to 20% left, 30% right, 8% top, and 25% bottom.
Since Bar Code 1 passes through the centering window, it will be read. Bar Code 2 does not
pass through the centering window, so it will not be read.
Note: A bar code needs only to be touched by the centering window in order to be read. It does
not need to pass completely through the centering window.
