setColorWithAlpha

The color is stored internally, and its HSV (Hue, Saturation, Value) components are extracted. The provided alpha value is scaled from a 0-255 range to a 0-100 range for internal representation.
Parameters
color
The base color (RGB integer value, alpha component is ignored and replaced by the alpha parameter).
alpha
The alpha value for the color, in the range 0 (transparent) to 255 (opaque). This will be internally scaled to a 0-100 range.
