CColorRef:new
The new method constructs a new instance of a CColorRef object. The CColorRef class includes 3 data members for R, G, and B color intensities. Three different constructor overloads are available to create a new CColorRef and initialize the data members.
C = CColorRef:new() Creates a new object with color initialized to (0,0,0). C = CColorRef:new( CColorRef2 ) This is a copy constructor. It creates a new CColorRef C initialized to the color of the CColorRef2 argument. C = CColorRef:new( R, G, B ) Creates a new CColorRef with members initialized to the R, G, and B values. |
Three overloads are provided for this method. They create a default CColorRef, a copy of a CColorRef, or an initialized CColorRef. If you pass something other than nil, a CColorRef, or data member values—such as a string—the default constructor is used.
The following script fragment computes the equivalent gray intensity using 2 different constructors:
A = CColorRef(255,140,5) |
-- create CColorRef A with values |
B = CColorRef:new( A ) |
-- copy A to a new CColorRef B |
n = A:ToGray(B) |
-- complement the color |
Printf("%d,%d,%d -> %.2lf", A.R,A.G,A.B,n) |
-- result: 255,140,5 -> 158.19 |
Printf("%d,%d,%d -> %.2lf", B.R,B.G,B.B,n) |
-- result: 255,140,5 -> 158.19 |
