0x00000006	Caption	Caption type zone.
0x00000007	Title	Title type zone.
0x00000008	Other	Other zone type.
0x00000009	AutoGraphic	Zone containing graphics (sure).
0x0000000A	VerticalText	Vertical characters. For Asian characters only.
0x0000000B	LeftRotatedText	Left rotated text (90 degrees counter clockwise). For Latin, Greek and Cyrillic characters only.
0x0000000C	RightRotatedText	Right rotated text (90 degrees clockwise). For Latin, Greek and Cyrillic characters only.

The OcrZoneType is used to classify the zone into one of the three basic zone-categories: flowing text, table or graphics. For these, use OcrZoneType.Text, OcrZoneType.Table, and OcrZoneType.Graphic respectively.

For flowing text, any of the following text types can appear instead of OcrZoneType.Text: OcrZoneType.Column, OcrZoneType.Header, OcrZoneType.Footer, OcrZoneType.Caption, OcrZoneType.Title, OcrZoneType.VerticalText, OcrZoneType.LeftRotatedText, OcrZoneType.RightRotatedText or OcrZoneType.Other.

One of these values is typically created by the page-layout decomposition (auto-zoning) process of the page, however they have the same meaning for the recognition algorithms: the zone contains flowing text.

The OcrZoneType.Table type is for table-type zones. In this type of zone is specified, the OCR engine will try to reconstruct the original table text layout of the zone in the final output document.

For graphic zones use the OcrZoneType.Graphic type. If OcrZoneType.Graphic is specified, no recognition will be run on the zone and all other recognition related settings will be ignored. The related OcrZoneType.AutoGraphic type can appear as the result of the page-layout decomposition (auto-zoning) process, and also signifies a graphic zone. The difference is, OcrZoneType.Graphic is the type that you as the user set in the zone to denote a graphic zone that contain no text, OcrZoneType.AutoGraphic is the type set by the engine during auto-zoning.
