# System Parameters

'BD' | Use Windows GDI+

## Description

(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.)

## Default

On – Windows GDI+ will be used.

## Example

Curved Line: Smooth | Curved Line: Uneven
