m. Encoding Type

• Encoding Type is the barcode formats that able to support.

• Supported Encoding type as below:

❖ Codebar

❖ Code 39

❖ Code 93

❖ Code 128

❖ EAN 8

❖ EAN 132/5 Industrial

❖ 2/5 Interleaved

❖ All

n. Zoom Factor

• Zoom factor is used to set the inspection size of the barcode.

• When Zoom factor set to 0.5 (50% of original barcode size)

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.
