The SkewAngle property returns or specifies the slant angle of the tile in a texture-fill pattern.
Examples:
The following VBA example creates a texture pattern that is rotated by 45° and skewed by 10°.
Sub Test()
Dim s As Shape
Dim tf As TextureFill
Set s = ActiveLayer.CreateRectangle(0, 0, 4, 4)
Set tf = s.Fill.ApplyTextureFill("Scribbles")
tf.SetProperties 14430, 5, 90
tf.RotationAngle = 45
tf.SkewAngle = 10
End Sub
