Using the Properties tab
6-12
The Bar Code Zone Properties window provides a Properties tab and a
Separation and Deletion tab. The Properties tab allows you to specify size and
quality characteristics of the bar code as well as the position of the bar code.
To define those characteristics fill out the Properties tab as described below:
1. If the bar code has a fixed width or height, enter these values in the
Bar code width and Bar code height fields. Enter the width and height
in 1/100 of an inch.
Making 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
bar code width and height is "0."
NOTES: 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.
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 in.).
When specifying a bar code height and/or width, the tolerance is
±10% (e.g., if you specify 20/100 for the bar code height, any bar
code between 18/100 and 22/100 in. will be detected).
2. Set one of the following Position options:
• Anywhere—select this option if the bar code can appear anywhere on the
image. This often occurs when bar code labels are used on documents.
When drawing a zone around the bar code, draw it precisely around one bar
code label somewhere on the page, and select the Anywhere option.
NOTE: In Capture Software v6.0 or higher, when looking for Anywhere bar
codes, Capture Software searches the image from top to bottom for
horizontal and vertical bar codes. This search order is important to
understand if you have more than one Anywhere bar code on a page.
In all previous versions of Capture Software, the search order is
different: Top to bottom for horizontal bar codes and left to right for
vertical bar codes.
• Zone—if a bar code is always in the same position, enable the Zone
option. This increases bar code reading performance. The Zone option is
the default.
- Alternatively search on 180° rotated images—this option can only be
used when the Zone option is enabled. When bar code reading is
unsuccessful, Capture Software will also look for the zone after rotating
an image 180 degrees. This slows down bar code reading, but prevents a
bar code read failure because a page was scanned upside down. The
image is not permanently rotated unless the Rotate based on bar code
option is selected.
- Rotate based on bar code—this option rotates either the document
or attachment in the same orientation as the orientation of the bar code
depending on the level (document or attachment) selected in the
Separation and Deletion tab. For document rotation, all of the pages
of the document will be rotated in the same manner as the lead page
containing the bar code zone. If required, only one bar code zone should
have the Rotate based on bar code option enabled.
Capture Software can determine if a bar code is rotated 180 degrees and
will rotate the bar code page 180° to display it in the correct orientation.
NOTE: Batch rotation is not supported in Capture Software.
