Sample: Y1 = 20 %, Y2 = 70 %; X1 = 10 %, X2 = 80 %
Note The limitation of the image memory for the selected values is not displayed graphically in the
dialog box.

7. Click the O
PTIMIZATION
P
ARAMETERS
button.
The O
PTIMIZATION
tab opens ( Fig. 10-15 ).
8. Adapt the following parameter values if necessary:
Tolerate L-pattern errors:
The ICR can expand the search algorithm for detecting finder patterns for gaps in the
code print of a code. The rest zone of the code must be at least five cell sizes in this
case, however.
¾
Deactivate the checkbox.
Optimize only even patterns:
¾
Click this checkbox if curved structures in the same size as the symbol appear in the
image.
Decoder retry on ...
... corrupted L-pattern:
When evaluating the image memory, the ICR uses a more complex search algorithm.
