The opacity multiplier applied to the referenced wire.
The opacity multiplier is clamped to the [0, 1] range when set.
Setting a new value overwrites any existing opacity override for that wire.
Setting this property has no effect when the WireReference has no associated WireReference.Context, such as when it is default.
Throws ObjectDisposedException when you access this method after you call Context.Dispose on the context.
Reduce the opacity of a wire to draw it semi-transparently in the graph canvas, for example to de-emphasize inactive connections.
WireReference wire = context.GetWireReference(outputPortID, inputPortID); wire.Opacity = 0.5f;
