If Enable Image Cropping is selected, set the pixel addresses from (0,0) to (639,479) to crop to.
Columns are numbered from 0 to 639, rows from 0 to 479. Specify four values for Top, Left, Bottom, and Right, 
where Top and Bottom correspond to row pixel addresses, and Left and Right correspond to column pixel 
addresses. For example, for a 4 row x 8 column image in the extreme bottom-right section of the image, set the 
following values:
Top = 476, Bottom = 479, Left = 632, Right = 639
To set the pixel address to crop to, capture each Pixel Address bar code followed by three bar codes from 
 which represent the value. Leading zeros are required, so to enter a value of 3, 
for example, capture 003
Top Pixel Address
(0 - 479 Decimal)
Left Pixel Address
(0 - 639 Decimal)
Bottom Pixel Address
(0 - 479 Decimal)
Right Pixel Address
(0 - 639 Decimal)
