IOcrEngine is a wrapper for different OCR engines. Each engine contains additional features and functionalities that can be queried and updated using the IOcrSettingManager interface.
Obtain an instance of the IOcrSettingManager associated with an engine through the IOcrEngine.SettingManager property.
Use the IOcrSettingManager.GetSettingNames and IOcrSettingManager.GetSettingDescriptor methods to programmatically obtain setting names, value types and ranges.
Alternatively, consult the following links for valid settings for each engine:
Choosing which draw engine to use in an application depends, in part, on which platforms the application is targeted for deployment:
If an application will be deployed exclusively to Windows platforms, use DrawEngineType.DefaultEngine. It is based on Windows GDI/GDI+ and produces the fastest rendering.
If an application will be deployed to both Windows and non-Windows platforms (such as Linux, Android, macOS, iOS, and Universal Windows Platform (UWP)), use DrawEngineType.MultiplatformEngine. This ensures identical rendering across all platforms.
For more information, refer to LEADTOOLS Draw Engine and Multi-Platform Considerations and RasterImage and GDI/GDI+.
