Description
Mirroring (only for data matrix codes):
Saved: If the code to be read is mirrored com-
•
pared with the saved code, the reader does
not decode the code to be read.
Dynamic: The reader also decodes codes that
•
are mirrored compared with the saved code.
Saved: The reader does not use all the image
•
enhancement filters and therefore achieves a
faster read result (including "NOK").
Dynamic: This setting improves the read relia-
•
bility with particularly poor code qualities, for
example on metal surfaces.
This parameter has no effect on PDF417 codes.
Description
Height of the barcode in pixels:
Saved: The reader decodes barcodes with a
•
height similar to that of the saved code faster.
Dynamic: The reader decodes a barcode
•
regardless of its height.
Length of the barcode in pixels:
Saved: The reader decodes barcodes with a
•
length similar to that of the saved code faster.
Dynamic: The reader decodes a barcode
•
regardless of its length.
Number of bars in the barcode.
Saved: The reader decodes only barcodes
•
that have the exact same number of bars as
the code used to save the program.
Dynamic: The reader can decode a barcode
•
regardless of the number of bars.
Length of the quiet zone.
Saved: The reader adapts itself to the length
•
of the quiet zone of the saved code to provide
faster and more reliable decoding.
Dynamic: The reader uses the default value
•
for the minimum quiet zone length.
