These properties allow you to set the image operations for all forms that are processed against the selected form set. Not all operations are designed for use at all bit depths. Some operations are designed to work only on bitonal images and some only on color/grayscale images. While, some operations work with any bit depths. The ScanFix Xpress help document will include this detailed information.
You can use the Validate button in FormAssist to verify that the selected operation(s) and order of operations are valid for the bit depth of the image being processed.
