The OriginX property returns or specifies the horizontal offset of a texture-fill tile from the lower-left corner of its parent shape. The OriginX property is measured in document units.
Examples:
The following VBA example applies a texture fill to a rectangle and offsets the tile by 1" to the left.
Sub Test()
Dim s As Shape
Dim tf As TextureFill
Set s = ActiveLayer.CreateRectangle(0, 0, 4, 4)
Set tf = s.Fill.ApplyTextureFill("Above the Storm", "Samples 9")
tf.OriginX = 1
End Sub
