Normally, the developer will want the control to observe the actual high-contrast setting for the local machine, which it does when no value is assigned to this property.
In cases where it is convenient to force the control to behave as if high-contrast mode is enabled/disabled, this property can be set accordingly. In this case, image resolution will proceed as if the actual high-contrast setting is that which corresponds to the value of this property.
By default, this property uses the HighContrast property of the SystemInformation class to determine whether high-contrast mode is enabled, and returns that value.
