Property Value

When anti-aliasing is enabled, the shapes are drawn with smooth edges, which affects both shape filling and path drawing.

Anti-aliasing uses 16x16 subpixels per pixel to achieve smooth edges. This means that anti-aliased drawing is slower than aliased drawing.

The following images provide a few examples regarding anti-aliasing:

Description	Image Example
Filling a polygon with AntiAliasing = .
Filling a polygon with AntiAliasing = .
Drawing a Path with AntiAliasing = , FastThinLines = . This is the default configuration of these properties.
Drawing a Path with AntiAliasing = , FastThinLines = , DrawPathPixelOffset = Half. Note that the lines are more jagged than above.
Drawing a Path with AntiAliasing = , DrawPathPixelOffset = Half. The lines are much smoother.
Drawing an ellipse with AntiAliasing = , FastThinLines = . The image is zoomed in for better visibility.
Drawing an ellipse with AntiAliasing = , FastThinLines = , DrawPathPixelOffset = Half. The image is zoomed in for better visibility.
Drawing an ellipse with AntiAliasing = , DrawPathPixelOffset = Half. The image is zoomed in for better visibility.
