public double getDoubleValue(String settingName)
Unique setting name. If the IOcrEngine does not support the setting with the unique name settingName, an exception will be thrown. You can check which settings the engine supports by using GetSettingNames or IsSettingNameSupported.
The current double value of the setting with the unique name settingName.
The settingName setting must be a "double" type setting, otherwise; this method will throw an exception. To get the type of a setting along with other information such as its friendly name and range use the GetSettingDescriptor method.
To set the value of a double setting, use SetDoubleValue.
You can also set the value of any setting from a string (where the string will be converted to a compatible type) using SetValue. To get the value of any setting as a string, use GetValue Note that settings of type OcrSettingValueType.BeginCategory and OcrSettingValueType.EndCategory have no values and will throw an exception if you try to get or set their values.
You can use the different methods of the IOcrSettingManager interface 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 GetSettingNames method. The GetSettingDescriptor method 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 OcrSettingValueType.Integer, you can use the GetIntegerValue to get the current value of the setting and the SetIntegerValue to change its value. Refer to IOcrSettingManager for a complete example.
For a list of supported engine-specific settings and their meanings, refer to OCR engine-specific Settings.
For an example, refer to IOcrSettingManager.
