Patch Code Recognition

Overview

A patch code is a pattern of horizontal black bars separated by spaces and typically

placed near the leading edge of a document to be scanned. It can be used to separate

documents or to stop the scanner. You may perform patch code recognition if you are

using an ImageControls-based or ISIS-based application and one of the following is

true:

• You purchased the VRS for Professional Scanners with the Adrenaline Image

Processing Engine bundle.

• You are using VRS in combination with a Kofax 650iMV, 650iHV, or an

Adrenaline 650i as your SCSI scanner controller.

The Patch Code Properties dialog box, shown in Figure E-1, can be used to enable,

disable, or specify the location of a patch code. In VCDemo, the Patch Code dialog box

is accessed via the Imaging menu. Other patch code options are set from the Units

option on the File menu in VCDemo.
