Image Cropping
This parameter crops a captured image. If Disable Image Cropping is selected, the full 640
x 480 pixels are presented. If Enable is selected, the decoder crops the image to the pixel
addresses set in Crop to Pixel Addresses.
Enable Image Cropping
Crop to Pixel Addresses
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, scan each Pixel Address bar code followed by three bar
codes from Appendix D, Numeric Bar Codes which represent the value. Leading zeros are
required, so to enter a value of 3, for example, scan 0, 0, 3.
