Public Member Functions

 SquareTranspFillAttribute ()
 Default Constuctor for fill attribute values.
virtual NodeAttribute * MakeNode ()
 Make a AttrSquareFill node from this graduated fill attribute.
virtual DocCoord * GetEndPoint2 ()
virtual void SetEndPoint2 (DocCoord *Pos)
 Sets the End Point of this fill.
virtual DocCoord * GetEndPoint3 ()
virtual void SetEndPoint3 (DocCoord *Pos)
 Sets the End Point of this fill.
virtual BOOL IsPerspective ()
virtual void MakePerspective ()
 Make the fill perspectived. This should be called just before it is transformed by the moulder, so it can validate the 4th control point.
virtual void RemovePerspective ()
 Removes perspective from this fill.
virtual BOOL IsASquareFill ()
virtual ColourFillAttribute * MakeSimilarNonTranspFillGeometry (double TransparencyScale)
 Creates a non-transparent version of this transparent fill attribute. (The original use of this was so airbrushes could maintain their fill's transparency geometry).
virtual INT32 GetGeometryShape ()
