OmrFormField Class

A single rectangular region on a form that defines an OMR (optical mark) area on a blank (not filled-in) form so that an OMR reading process can be performed on the filled form during form processing.

Remarks

Fields are defined for each page in the processing engine. All fields require you fill in the Property specifying where the field is located, and a Name Property.

Fields can be added or retrieved through the FormProcessingEngine.Pages property. Once fields are defined, they can be loaded/saved from disk using the FormProcessingEngine.LoadFields and FormProcessingEngine.SaveFields methods, allowing you to define MasterForm fields just once and save them to disk. LEADTOOLS supports TextFormField, OmrFormField, BarcodeFormField, ImageFormField, and custom user-defined fields derived from FormField. When obtaining processing results, you should check for the type of each field, and cast it to the appropriate type in order to obtain the field specific results (barcode, image, etc).
