The Data property returns or specifies the string representing a bitmap pattern. The pattern is encoded with a special algorithm to allow the binary bitmap data to be represented in a text form. Data is the default property of the PatternCanvas class.
Examples:
The following VBA example creates a new checkerboard pattern that is 16 × 16 pixels and then applies it to a rectangle.
Sub Test()
Dim c As New PatternCanvas
c.Data = "%%['$aH,&A5&0C"
With ActiveLayer.CreateRectangle(0, 0, 3, 3)
.Fill.ApplyPatternFill cdrTwoColorPattern
.Fill.Pattern.Canvas = c
End With
End Sub
