Image Enhancement in Workflows
To incorporate image enhancement in a workflow choose its icon in the Workflow
Assistant.
The following options are available:
Display images for manual enhancement - during the execution of a workflow, each loaded
image will be displayed for manual editing.
Apply enhancement template - an already saved enhancement template will be applied
automatically to the image while being processed by the workflow.
Apply enhancement template and display - the workflow will apply the selected image
enhancement template, and will also display the image so that you can make further edits to it.
Zones and backgrounds
Zones define areas on the page to be processed or ignored. Zones are rectangular or irregular,
with vertical and horizontal sides. Page images in a document have a background value:
process or ignore (the latter is more typical). Background values can be changed with the tools
shown. Zones can be drawn on page backgrounds with the tools shown under Zone Types and
Properties (see later).
Process areas (in process zones or backgrounds) are auto-zoned when they are sent to
recognition.
Ignore areas (in ignore zones or backgrounds) are dropped from processing. No text is
recognized and no image is transferred.
Automatic zoning
Automatic zoning allows the program to detect blocks of text, headings, pictures and other
elements on a page and draw zones to enclose them.
You can Auto-zone a whole page or a part of it. Automatically drawn zones and template
zones have solid borders. Manually drawn or modified zones have dotted borders.
Auto-zone a page background
Acquire a page. It appears with a process background. Draw a zone. The background
changes to ignore. Draw text, table or graphic zones to enclose areas you want manually
