Detailed Description
OCR (Optical Character Recognition) Engine Interfaces without Layout Analysis.
This set of interfaces offers the OCR engine which does not support Layout Analysis on full images. User shall implement their own layout solution
RecognizeBlockL recognizes text information in a single block area regardless of content
RecognizeSpecialRegionL recognizes text information in a single block area and its content sensitive. User can select three different types of contents: e-mail address, phone numbers or web addresses

- TRegionInfo
Note that this class shall be used together with TEngineType set to EEngineRecognizeBlock
