a. Barcode Format

• The barcode formats that able to support are show below:

b. Scale X & Scale Y

• Scale X and Scale Y used to set the inspection size of the barcode. There

have the range of 0.1 to 1.0 which covered 10% of orignal barcode size to

100% of original barcode size.

• Scale X is the vertical direction while scale Y is the horizontal direction.

• When scale X and scale Y set to 0.5, the barcode after rescale will display

at center of barcode inspection box. (red)

c. Preprocessing

• Morph opening: This is used to preprocess for normal barcode.

• Morph Closing: This is used to preprocess for inverted barcode.

d. Morph Kernel Size

• This is used to set morphing percentage.
