Percentage opacity of the icon
Member of PRIM_MD.RadioButton (PRIM_MD.RadioButton)
Data Type - Integer
The IconOpacity property denotes the appearance of the RadioButton in terms of its interaction with the background. The default is 100; entirely opaque. No background will be visible at all. As the value decreases, more and more of the background will become visible through the RadioButton. When the value is 0 the icon will be entirely transparent and only the background will be visible. Note: a RadioButton with opacity of 0 is not visible to the user but will continue to function as normal and is still both visible and enabled.
