FormFix uses the FieldTypeClassificationProcessor to classify the content of text fields as containing either handwritten or machine typed text. The results of running the processor on an image are returned as a set of confidence values that describe the type of text in the field. This processor can be used to identify the type of text in an image and allow a program to handle processing that image differently depending on that result. Field Type Classification is only available on 64-bit platforms.

The FieldTypeMatch object contains the information about a single FieldType within a result. The FieldTypeClassificationProcessor is the class used to identify the type of text in a form field. It has methods to perform field type classification, read and write to and from a stream, and has properties for useful parameters that control identification process. The FieldTypeResult object contains the result of the FieldTypeClassificationProcessor.Identify function.
