Overview

The concept of a field in the forms processing world is described as a single rectangular region on a form defined by pixels, along with a type, and various other attributes. Frequently, a field will contain a single user-filled item, such as a last name or phone number.

FormDirector implements this concept as the type Field. This type exposes several parameters to allow storage of various attributes of a field.

In FormDirector, a Field is associated with exactly one FormDefinition, and a FormDefinition is associated with zero or more Fields. When a FormDefinition is written to persistent storage, all of the associated Fields are written to persistent storage at the same time. And, when a FormDefinition is retrieved from persistent storage, all of the associated Fields are retrieved at the same time.

Purpose

The primary purpose of a Field object is to contain the parameters you need to process a single field on a form. Those parameters are a rectangle, measured in pixels relative to the top left corner of the template image; a set of construction parameters, a set of processing operations, and some miscellaneous data.
