Barcode Overview

Barcode fields allow barcodes, such as the familiar UPC code, to be read from a filled form image.

When a Barcode field is defined on a form template in FormAssist:

1. the Barcode Xpress engine reads the respondent form, and
2. recognizes the barcode according to the parameters specified.
   

FormAssist window with Barcode tab open and a Barcode field highlighted. 

The image above displays an example Barcode field highlighted on both the Tree and Image Views of the FormAssist window.

• The Tree View displays the name and icon of the field.
• The Image View outlines the area currently selected.

It is recommended to use the "Clip" method of dropout on the Dropout tab to improve barcode processing accuracy.

See the Image Enhancement and Dropout Properties topics in this section for more information on how to improve recognition processing performance. To create Barcode fields, see the Define and Create Fields > Barcode Fields topic.

There are different folder tab options available in the Properties View of the FormAssist window, depending on which field type is currently selected.

ScanFix Xpress	The ScanFix Xpress settings can be used to enhance the image by: allowing the Barcode Xpress engine to locate and read the barcode. determining the respondent marked fields rather than irrelevant marks. There are many choices to choose from and they are performed in the order they are listed. See the ScanFix Xpress Properties topic within the Field section for detailed information on each property.
