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.
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.

Code shape: Specify the shape of the code to be found. For code type Data Matrix: (rectangular,
square, arbitrary). For code type QR code: (Model 1, Model 2, arbitrary).

Columns: Specify the number of columns of the module.

Rows: Specify the number of lines of the module.

Module size (Pixel): Specify the size of a module.

Gap between the modules: Specify whether gaps may occur between the modules.
