new_colorref

new_colorref

The new_colorref function is a non-class version of the CColorRef:new method which creates and returns a new CColorRef object. The CColorRef class includes 3 properties for R, G, and B color intensities.

Syntax

C = new_colorref()

Creates a new object with color initialized to (0,0,0).

C = new_colorref( CColorRef_old )

This is a copy constructor. It creates a new CColorRef C initialized to the color of the CColorRef_old argument.

C = new_colorref( R, G, B )

Creates a new CColorRef with members initialized to the R, G, and B values.

Remarks

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.

Example

The following script computes the equivalent gray intensity using 2 different constructors:

A = CColorRef(255,140,5)	-- create CColorRef A with values
B = new_colorref( 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
