The StartX property returns or specifies the horizontal starting-coordinate of a fountain-fill vector. For radial, rectangular, and conical fills, the starting point is the center point of the fill. The StartX property is measured in document units.
Examples:
The following VBA example draws circles around the starting and ending points of the fountain-fill vector.
Sub Test()
With ActiveShape.Fill.Fountain
ActiveLayer.CreateEllipse2 .StartX, .StartY, 0.2
ActiveLayer.CreateEllipse2 .EndX, .EndY, 0.2
End With
End Sub
