To create and store an image enhancement template, first bring an
image file into the Image Enhancement window, then carry out your
preprocessing steps and add them to the History clicking the Apply
button. When you are done, choose Save Enhancement Template
from the File menu. Browse to your preferred destination and save
the template file (with the extension .ipp).
To carry out the set of modifications saved in the template file on
another image, simply open the new image in the Image
Enhancement window and choose Load Enhancement Template
from the File menu.
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).
