Zone processing
Zone processing is available on the i100 Series Scanners.
Some applications have a requirement to store part of an image
in color or grayscale and the rest of the image in bi-tonal format
(this saves storage space by not storing the entire image in color
or grayscale). Zone processing is a fixed crop window (the zone)
located relative to the upper left corner of a document. It allows
the operator to select via the host application areas on the
document to be delivered in either color, grayscale or bi-tonal
format. Different zones may be selected for both the front and
rear of the image.
This feature may be used in conjunction with auto cropping.
Following is an example of producing a color zone.
