| 'BD' | Use Windows GDI+ | 
(Windows Only)
The 'BD' (Better Drawing) parameter controls whether Windows GDI+ is used to provide smoother curved and angled lines when the following shapes are drawn: Arc, Ellipse, Pie, Line and Polygon.
If this parameter is On, Windows GDI+ will be used.
If this parameter is Off, Windows GDI will be used, which is sufficient for straight horizontal and vertical lines; however, curved and angled lines will appear slightly jagged and uneven.
(The 'BD' system parameter was added in PxPlus 2020.)
On – Windows GDI+ will be used.
