(Inherited from BaseTextExtractor.)
Public propertyOCRAutoModeMinExistingTextLength
Applies to OCRMode.Auto only: Min total length of existing text on current page to decide if OCR should be run or not. If the length of text is lesser than this property then library runs OCR for this page. Otherwise it extracts the existing text only.

(Inherited from BaseTextExtractor.)
Public propertyOCRCacheMode
OCR results caching behaviour. Turned off by default (no cache is used). In "WholePage" caching mode you may save processing time as the SDK will check if need to re-run OCR on the page or can just pull results from previously cached OCR results.
(Inherited from BaseTextExtractor.)
Public propertyOCRCorrections
Collection of corrections automatically applied to recognized text to fix repeating recognition errors.
(Inherited from BaseTextExtractor.)
Public propertyOCRDetectPageRotation

(Inherited from BaseTextExtractor.)
Public propertyTableYMinIntersectionRequiredInPercents
Y coordinate tolerance factor when working with stuctured (table) data. This option controls how much % of the cell rectangle (by Y coordinate) should intersect with row to belong to it.
