The Fountain property returns a fountain fill (or FountainFill object) representing the settings for a fountain-fill transparency.
Examples:
The following VBA example sets the direction angle of all fountain-fill transparencies to 45°.
Sub Test()
Dim s As Shape
For Each s In ActivePage.Shapes
If s.Transparency.Type = cdrFountainTransparency Then
s.Transparency.Fountain.SetAngle 45
End If
Next s
End Sub
