Crop To Pixel Addresses - Motorola Symbol PL4507 Integration Manual

Crop to Pixel Addresses

Parameter # F4h F0h 3Bh (Top)
Parameter # F4h F0h 3Ch (Left)
Parameter # F4h F0h 3Dh (Bottom)
Parameter # F4h F0h 3Eh (Right)
If Enable Image Cropping is selected, set the pixel addresses from (0,0) to (751,479) to crop to.
Columns are numbered from 0 to 751, 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 = 744, Right = 751
To set the pixel address to crop to, scan each Pixel Address bar code followed by three bar codes from
D, Numeric Bar Codes
0, 0, 3.
NOTE The decoder has a minimum cropping resolution of four pixels; increment and decrement cropping
addresses in multiples of four. Other values are rounded up. For example, choosing to crop from the top at
addresses 0, 1, or 2 (removing 1, 2, or 3 pixels) has the same result as cropping at address 3; this
removes four rows from the top.
Top Pixel Address
(0 - 479 Decimal)
Bottom Pixel Address
(0 - 479 Decimal)
which represent the value. Include leading zeros, so to enter a value of 3, for example, scan
Imager Preferences 5 - 17
Left Pixel Address
(0 - 751 Decimal)
Right Pixel Address
(0 - 751 Decimal)
