Fill Pattern

Object ID of a Picture Graphic object to be used as the fill pattern. Ignored if fill type ≠ 3.

To change from fill type 0, 1 or 2 to fill type 3, the Working Set must first change the fill pattern attribute and then the fill type attribute in order to avoid errors in the VT.

If this order is not followed, the behaviour of the VT cannot be predicted and is proprietary.

If fill type is 3 and the fill pattern attribute is NULL, no fill is performed by the VT.
