A zone is a rectangular area in the image, up to full size, containing a feature of interest to the user. The image data covered by each zone is handled and processed (and typically recognized) separately, according to zone-specific parameters. The zones of an ImGearRecPage Class image form a list, the zone list, which is attached to the image. The zone list can be examined at any time with the Zones Property of ImGearRecPage Class.
The characterizing attributes of a zone are the following:
- Size and position
- Identifier of the zone (identifies the zone in the zone list)
- Type (determines the role of the zone in the image layout, i.e., Flowed text, Table, or Graphic)
- Filling method (specifies the nature of the zone content, i.e., how the zone's area was supposed to be filled originally)
- Recognition method (the recognition module to be applied for the zone)
- A Character Set filter
- What kind of checking is enabled for the zone content
- User dictionary section assigned to the zone (for UD-checking)
- Checking event assigned to the zone for user-written checking
The zone's filling method (fm) can take one of the following ImGerRecFillingMethod Enumeration values:
- OMNIFONT : denotes machine printed text with any typeface that is not too stylized
- DRAFTDOT9 : denotes a 9-pin draft dot-matrix printout
- DRAFTDOT24 : denotes a 24-pin draft dot-matrix printout
- OCRA : denotes OCR-A zone filling
- OCRB : denotes OCR-B zone filling
There are two special filling methods worth mentioning separately:
- NO_OCR : denotes that no recognition should be attempted
- DEFAULT : allows a number of zones on the image to be handled together. For zones having this filling method, the recognition engine will apply a common value according to the setting previously given by the DefaultFillingMethod property of ImGearRecRecognitionSettings Class.
