Specifies whether to use the services of the Mathematica notebook front end in rendering the image to display.
If the front end is used, then depending on various circumstances you might see a special "Mathematica Server" instance of the front end appear in the Windows taskbar. This separate instance of the front end is used only for rendering services in the background. It has no user interface and cannot be brought the foreground. It is completely managed for you by .NET/Link.
This setting is ignored if the PictureType property is set to "StandardForm" or "TraditionalForm", as typeset output always requires the services of the front end.
