public IOcrTableZoneManager TableZoneManager { get; } 
property IOcrTableZoneManager^ TableZoneManager { 
   IOcrTableZoneManager^ get(); 
TableZoneManager # get  (IOcrPage) 

Property Value

An instance of IOcrTableZoneManager that can be used to manipulate the cells of table zones inside this IOcrPage, or a null reference (Nothing in VB), if the current OCR engine does not support manipulating the cells of table zones.


This object contains method auto-detect, get information, update, split and merge the cells of a zone of type OcrZoneType.Table contained in this IOcrPage. For more information, refer to IOcrTableZoneManager.
