This function gets all settings descriptors at once.
LEADTOOLS OCR Module - LEAD Engine contain specific additional features and functionality that can be queried and updated using different L_OcrSettingManager handle functions.
You can use the different methods of the L_OcrSettingManager handle to get and set the engine-specific settings. Each setting has a unique name (a string value). You can get all the settings available to the current OCR engine through the L_OcrSettingManager_GetSettingName method. The L_OcrSettingManager_GetSettingDescriptor and L_OcrSettingManager_GetSettingDescriptors methods returns a description of the setting (its type, friendly name and value range), you can then use the various setting get and set methods to query and change the value of a certain setting. For example, if the setting type is L_OcrSettingValueType_Integer, you can use the L_OcrSettingManager_GetIntegerValue to get the current value of the setting and the L_OcrSettingManager_SetIntegerValue to change its value. Refer to L_OcrEngine_GetSettingManager for a complete example.
Note: You should call L_OcrMemory_Free after you are done with these setting descriptors in order to free the allocated memory.
For an example, refer to L_OcrEngine_GetSettingManager
