5.7.14.2.1
Symbol size
You can use the
parameter to restrict the permitted number of lines and co-
lumns of the codes.
The code dimensions are calculated from the symbol size and module size. For this, the
symbol size is multiplied by the module size.
To reduce the decoding time, it may make sense to set the actual symbol size of the
code and thus exactly specify the expected code size.
• F
REE
: All AIM/ISO/IEC-specified Data Matrix ECC200 sizes are decoded.
• F
IXED
parameters can be used to
select fixed symbol sizes. Only codes with one of these defined symbol sizes are read.
5.7.14.2.2
Fixed length 1
parameter can be used to select a fixed symbol size. Only codes with this
symbol size are read.
By defining certain permitted symbol sizes, you restrict the range of codes to be read. This
can lead to a reduction in the decoding time.
5.7.14.2.3
Fixed length 2
parameter can be used to select a fixed symbol size. Only codes with this
symbol size are read.
By defining certain permitted symbol sizes, you restrict the range of codes to be read. This
can lead to a reduction in the decoding time.
5.7.14.2.4
Fixed length 3
parameter can be used to select a fixed symbol size. Only codes with this
symbol size are read.
By defining certain permitted symbol sizes, you restrict the range of codes to be read. This
can lead to a reduction in the decoding time.
