Sets the specified fill to a one-color gradient.

public void SetOneColorGradient(Color color, double degree, GradientStyleType style, int variant)

Parameter	Type	Description
color	Color	One gradient color.
degree	Double	The gradient degree. Can be a value from 0.0 (dark) through 1.0 (light).
style	GradientStyleType	Gradient shading style.
variant	Int32	The gradient variant. Can be a value from 1 through 4, corresponding to one of the four variants on the Gradient tab in the Fill Effects dialog box. If style is GradientStyle.FromCenter, the Variant argument can only be 1 or 2.
