Minimum length
— enter a number for the minimum length of the bar code
value. By default, this option is set to the length of the tested bar code value. If
a value is not found or the value is equal to or greater than six characters, the
default will be set to “6.” It is recommended that the minimum length parameter
be set at six characters or fewer to allow
Kodak
Capture Pro Software to retain
bar code values in cases of a partial reading.
If the
Partial Reading
option is not required or enabled, then the mask and
minimum length settings can be used in combination to restrict even further the
bar code values that are retained.
For example:
Mask: 9(10)
Minimum bytes: 6
retains bar code values between six and ten digits, while
Mask: 9(10)
Minimum length: 10
retains bar code values only if they are exactly ten digits.
Bar code width and Bar code height
—
if the bar code has a fixed length or
height, enter these values in 1/100ths of an inch. An entry in one or both of
these fields increases the performance of bar code reading. If one of the
dimensions is variable, enter
0
. The default is 0.
Bar code dimensions can vary depending on the amount of skew. Therefore, it
is recommended that you enter these values only when you are sure of the
dimensions of the bar code.
NOTE: You must specify a bar code height for bar codes that are smaller than
40 pixels high (e.g., at 200 dpi, 40 pixels is 20/100
ths
of an inch).
When specifying a bar code width and/or height, the tolerance is ±10%
(e.g., if you specify 20/100
ths
of an inch for the bar code height, any bar code
between 18/100
ths
of an inch and 22/100
ths
on an inch will be detected).
Type
— you may also select additional bar code types that will be considered
valid for this bar code zone. Although it is unusual that more than one bar code
type would be found within a zone, it is possible to select multiple bar code
types. For more information on bar code types, see the section entitled, “Bar
Code types” later in this chapter.
The more bar code types you select, the slower your scanning performance.
When you draw a bar code location,
Kodak
Capture Pro Software searches
the location for all bar code types. When successful, the software sets the bar
code type to the one found. Otherwise, a bar code type is not selected. There
are two exceptions:
• For Code 39 Extended and Code 39 HIBC bar codes, Capture Pro Software
may set the bar code type to Code 39. As a result, you may need to
manually select
Code 39 Extended
and
Code 39 HIBC
.
• For MSIPH bar codes, Capture Pro Software may set the bar code type to
MSI. As a result, you may need to manually select
MSIPH
.
