What has changed?
- The engines offered by LEADTOOLS have been renamed
- The OcrEngineType enumeration has been restructured
- New runtime files are required
- The default location for runtime files has been moved
- Some LEADTOOLS DLLs have been renamed
What are the new OCR engine names?The Advantage engine is now called the LEAD engine, and Professional is now OmniPage.
How does this affect my code?All references to OcrEngineType will need to be updated to reflect the new values.
OcrEngineType.Advantage -> OcrEngineType.LEAD
OcrEngineType.Professional -> OcrEngineType.OmniPage
OcrEngineType.Arabic -> OcrEngineType.OmniPageArabic
Where are the new runtime files?LEAD Engine:
C:\LEADTOOLS21\Bin\Common\OcrLEADRuntimeOmniPage Engine:
C:\LEADTOOLS21\Bin\Common\OcrOmniPageRuntimeOmniPage Engine 64-bit:
C:\LEADTOOLS21\Bin\Common\OcrOmniPageRuntime64OmniPage Arabic Engine:
C:\LEADTOOLS21\Bin\Common\OCROmniPageArabicRuntimeWhat are the new libraries?The following files are required for all engines:
- Leadtools.Ocr.dll
- Leadtools.dll
- Leadtools.Forms.Common.dll
- Leadtools.Codecs.dll
- Leadtools.Document.Writer.dll
- Leadtools.ImageProcessing.Core.dll
The LEAD engine requires Leadtools.OcrLEAD.Engine.dll and Leadtools.Ocr.Advantage.dll.
The OmniPage engine requires Leadtools.Ocr.OmniPageEngine.dll and Leadtools.Ocr.Professional.dll.
The OmniPage Arabic engine requires Leadtools.Ocr.OmniPageArabicEngine.dll and Leadtools.Ocr.Arabic.dll.
