Returns a value that indicates how dark or light a one-color gradient fill is. A value of 0 (zero) means that black is mixed in with the shape's foreground color to form the gradient; a value of 1 means that white is mixed in; and values between 0 and 1 mean that a darker or lighter shade of the foreground color is mixed in. Read-only Single.
This property is read-only. Use the OneColorGradient method to set the gradient degree for the fill.
Example
This example adds a rectangle to myDocument and sets the degree of its fill gradient to match that of the shape named "Rectangle 2." If Rectangle 2 doesn't have a one-color gradient fill, this example fails.
Set myDocument = ActivePresentation.Slides(1)
With myDocument.Shapes
gradDegree1 = .Item("Rectangle 2").Fill.GradientDegree
With .AddShape(msoShapeRectangle, 0, 0, 40, 80).Fill
.ForeColor.RGB = RGB(128, 0, 0)
.OneColorGradient msoGradientHorizontal, 1, gradDegree1
