Reflection properties of the start/stop pattern, decoded codeword yield, unused error
correction, modulation, decodability, defects
In the AIM DPM-1-2006 mode, a total of 8 characteristics are determined (for ECC200 / QR code
only):
Cell contrast, cell modulation, fixed pattern damage, decodability, axial non-uniformity (evaluation of
the width and height), grid non-uniformity (evaluation of the slope angle), unused error correction,
mean grey value of the light modules (0,70..0,86 → A; 0,86..1,0 and 0,55..0,7 → B; 0,4..0,55 → C;
0,25 .. 0,4 → D; below 0,25 → F).
NOTE
In order to be able to make the settings "Appearance" and "Code parameters" on the
tabs, you must set the Parameters on the "Common" tab to User defined.

Polarity: Specify whether the code is brighter or darker than the background.

Mirroring: Specify whether the code is mirrored.

Minimum contrast: Specify the minimum contrast of the matrix code.

Recognition: If the outer contour of the code exhibits disturbances, you should activate "Tolerant"
recognition. Otherwise, "Normal" recognition is sufficient.
