public float Opacity { get; set; }

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 . 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;
