Applies the percentage of reflectivity to the picture displayed over the button surface.
The value of this property can range from 0 (no reflectivity applied) to a value of 100 (maximum reflectivity). Lower or higher values will be automatically capped to the nearest valid value. The default value is 50.
Below you can see two buttons: the left one has a picture whose PictureReflectivityPerc property is set to 30, the right one has a picture whose PictureReflectivityPerc property is set to 100.
This property has no effect if the PictureReflectivityEnabled property is set to FALSE.
