Using zone templates
A template contains a page background value and a set of zones and
their properties, stored in a file. A zone template file can be loaded
to have template zones used during recognition. Load a template file
in the Layout Description drop-down list or from the Tools menu.
You can browse to network locations to load templates created by
others.
When you load a template, its background and zones are placed:
• on the current page, replacing any zones already there
• on all further acquired pages
• on pre-existing pages sent to (re-)recognition without any
zones.
With manual processing the template zones in the first two cases
can be viewed and modified before recognition.
With automatic processing the template zones can be viewed and
modified only after recognition.
With workflow processing, use the zone images step. This
combines two steps: load templates and manual zoning. To use a
zone template, click the Add button in the appropriate panel of the
Workflow Assistant, and select the zone template file to use. Then
make your choice between displaying images for manual zoning;
applying the zone template; or applying it and display the images.
Templates accept ignore and process zones and backgrounds. They
can therefore be useful to define which parts of the pages to process
with auto-zoning, and which parts to ignore. Process zones or
process background areas from a template may be replaced during
recognition by a set of smaller zones; specific zone types will be
assigned to these zones.
