public double DoubleMaximumValue { get; }
The maximum allowed value for the double setting.
You should not pass a value greater than DoubleMaximumValue when setting the value of the double setting.
If the double setting has no maximum value, DoubleMaximumValue will be set to Double.MaxValue.
This member is only valid if ValueType is OcrSettingValueType.Double.
For a list of supported engine-specific settings and their meanings, refer to OCR engine-specific Settings.
