Gets the current value of a double setting.
The settingName setting must be a "double" type setting, otherwise; this method will return an error. To get the type of a setting along with other information such as its friendly name and range use the L_OcrSettingManager_GetSettingDescriptor method.
To set the value of a double setting, use L_OcrSettingManager_SetDoubleValue.
You can also set the value of any setting from a string (where the string will be converted to a compatible type) using L_OcrSettingManager_SetValue. To get the value of any setting as a string, use L_OcrSettingManager_GetValue. Note that settings of type L_OcrSettingValueType_BeginCategory and L_OcrSettingValueType_EndCategory have no values and will return an error if you try to get or set their values.
Advantage OCR 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_Double, you can use the L_OcrSettingManager_GetDoubleValue to get the current value of the setting and the L_OcrSettingManager_SetDoubleValue to change its value. Refer to L_OcrEngine_GetSettingManager for a complete example.
