6.12 Function Centering
Centering window is used to narrow the field of view to make sure the imager reads
only those bar codes intended by the user. For instance, if multiple codes are placed
closely together, centering will insure that only the desired codes are read.
The centering window is specified as a percentage of the whole image. The default
centering window is 40% for top and left, 60% for bottom and right. The following
diagram illustrates the default top, bottom, left, and right pixel positions, measured
from the top and the left side of the whole image.
