Remarks

To set the properties of the alpha channel, call the MedicalViewerBaseCell.SetActionProperties method. To retrieve the properties call the MedicalViewerBaseCell.GetActionProperties method.

Alpha is the standard name for the Factor Value that indicates the factor to be applied to the lookup table. It is important to set the value of the lookup table to one of the following types: Sigmoid, Logarithmic or exponential. Valid values range from -1000 to 1000.

The mouse controls the actions as follows:

Click and hold the mouse to start the effect. When the assigned mouse button is released the action ends.
Dragging the mouse to the left decreases the center parameter.
Dragging the mouse to the right increases the center parameter.
Dragging the mouse up decreases the width parameter.
Dragging the mouse down increases the width parameter.
