Description
If the data matrix shows unusual differences in
brightness in the code area (for example when
one side is much brighter than the other), ena-
bling this option allows the reader to read the
code. However, this may take longer.
If the border is severely damaged, enabling this
option allows the reader to read the code. How-
ever, this may take longer.
If the image has single lines, enabling this option
may help to speed up decoding.
With image acquisition at an angle < 60 degrees,
enabling this option can make reading more relia-
ble.
Description
Polarity (only data matrix codes):
Saved: If dark code is saved on light back-
•
ground, the reader can read dark code on light
background faster. The same is true for in-
verse polarity, that is, light codes on dark
background.
Dynamic: Any code polarity is read, regardless
•
of whether the saved code was dark on light
background or light on dark background.
Number of rows and columns:
Saved: The reader decodes the data matrix
•
code faster if a data matrix code contains the
same number of rows and columns as the
saved code.
Dynamic: The reader can decode a data ma-
•
trix if the number of rows and columns differs
from the saved code.
