Version 16 of the LEADTOOLS OCR C DLL has changed from version 15 as follows:
LEAD'S robust OCR design now supports multiple OCR engines, giving you a choice of LEADTOOLS OCR Modules:
LEADTOOLS OCR Module - Professional: This new engine provides the fastest and most accurate automatic and manual zone detection, Unicode support, formatted output, auto-orientation, custom spelling dictionaries and MICR support. PDF and PDF/A output, ICR and OMR support is available.
The document handle for new engine is L_HDOC2.
The path for the new engine is available from the OCRPathProfessional16 key: HKEY_LOCAL_MACHINE\Software\LEAD Technologies, Inc.\OCRPathProfessional16.
The function naming convention for OCR Professional is L_Doc2xxx.
The demo naming convention for OCR Professional is Ocr2xxx.
LEADTOOLS OCR Module - Plus: our existing engine includes automatic and manual zone detection, formatted output, auto-orientation, custom spelling dictionaries and MICR support. PDF and PDF/A output, ICR and OMR support is also available.
The document handle for the existing engine remains L_HDOC.
The path for the previous engine is from the OCRPathPlus16 key: HKEY_LOCAL_MACHINE\Software\LEAD Technologies, Inc.\OCRPathPlus16.
Both engines can be installed on the same machine.
Continue to use existing code, with no code changes required.
At the same time, upgrade to the new engine for fastest possible performance on new or existing applications.
Both engines will run independently, with no conflict.
