    • alpha - (optional)(default=1) - real number between 0 or 1

public method

method	description
cobj:isEqual(cobj2)	if cobj (color object) is equal to cobj2 (that is, cobj and cobj2 has the same r,g,b, and alpha values) then return true

Static method

method	description
Color.rand()	creates Color object that has random color information (alpha=1)
Color.invert(cobj)	return color object that inverts cobj

Examples

local color1 = Color(255, 0, 0) local color2 = Color(0,255,0, 0.5) local BLUE = Color.BLUE local r = Rect(100,200) r:setStrokeColor(color1) r:fill(BLUE)
