3 - 7
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.
