EffectBlend.AccelerateSize property
Gets or sets whether or not the size accelerates along the path
Syntax:
Property Get AccelerateSize() As Boolean
Property Let AccelerateSize(ByVal Value As Boolean)

The AccelerateSize property returns or specifies whether the size of blend steps accelerates along the path for a blend.
Examples:
The following VBA example creates a non-uniform blend between a rectangle and a circle.
Sub Test()
Dim s1 As Shape, s2 As Shape
Set s1 = ActiveLayer.CreateEllipse2(2, 2, 1)
s1.Fill.UniformColor.RGBAssign 255, 0, 0
Set s2 = ActiveLayer.CreateRectangle2(4, 4, 1, 1)
s2.Fill.UniformColor.RGBAssign 255, 255, 0
With s2.CreateBlend(s1).Blend
  .LinkAcceleration = False
  .ColorAcceleration = 50
  .SpacingAcceleration = -50
  .AccelerateSize = True
End With 
End Sub
