int linearGradientColor(int startX, int startY, int endX, int endY, int startColor, int endColor, bool periodic = false);

Creates a two-point linear gradient color.

Argument	Default	Description
startX	(Mandatory)	The x coordinate of the starting point of the reference gradient line segment.
startY	(Mandatory)	The y coordinate of the starting point of the reference gradient line segment.
endX	(Mandatory)	The x coordinate of the ending point of the reference gradient line segment.
endY	(Mandatory)	The y coordinate of the ending point of the reference gradient line segment.
startColor	(Mandatory)	The color at the starting point of the reference gradient line segment.
endColor	(Mandatory)	The color at the ending point of the reference gradient line segment.
periodic	false	Specifies whether the gradient will repeat itself periodically. If the gradient does not repeat itself, the points that lie beyond the end points of the gradient line segment will assume the colors of the end points.

A 32-bit integer representing the linear gradient color.
