int radialGradientColor(int cx, int cy, int rx, int ry, int startColor, int endColor, bool periodic = false);

Creates a two-point radial gradient color.

Argument	Default	Description
cx	(Mandatory)	The x coordinate of the center of the radial gradient.
cy	(Mandatory)	The y coordinate of the center of the radial gradient.
rx	(Mandatory)	The horizontal radius of the radial gradient defining ellipse.
ry	(Mandatory)	The vertical radius of the radial gradient defining ellipse.
startColor	(Mandatory)	The color at the center of the gradient defining ellipse.
endColor	(Mandatory)	The color at the perimeter of the gradient defining ellipse.
periodic	false	Specifies whether the gradient will repeat itself periodically. If the gradient does not repeat itself, the points that lie outside the gradient defining ellipse will assume the color at the perimeter of the gradient defining ellipse.

A 32-bit integer representing the radial gradient color.
