GpSmoothingMode enumeration

Specifies the kind of smoothing (antialiasing) that is applied to lines and curves.

The setting is the SmoothingMode property of Graphics. A box filter that is 8 pixels wide and 4 high gives better results for lines that are nearly vertical than for lines that are nearly horizontal. A filter of 8 by 8 pixels gives equally good results for both and is slower. The first four members have the values of GpQualityMode.

Note

GDI+ replaces some of the values when they are set. A Graphics object that was given SmoothingModeHighQuality returns SmoothingModeAntiAlias when the property is read again, and one that was given SmoothingModeHighSpeed or SmoothingModeDefault returns SmoothingModeNone.

Member Value Description
SmoothingModeInvalid -1 Reserved.
SmoothingModeDefault 0 No smoothing is applied.
SmoothingModeHighSpeed 1 No smoothing is applied.
SmoothingModeHighQuality 2 Smoothing is applied with an 8 by 4 box filter.
SmoothingModeNone 3 No smoothing is applied.
SmoothingModeAntiAlias 4 Smoothing is applied with an 8 by 4 box filter.
SmoothingModeAntiAlias8x4 4 Smoothing is applied with an 8 by 4 box filter. Same value as SmoothingModeAntiAlias.
SmoothingModeAntiAlias8x8 5 Smoothing is applied with an 8 by 8 box filter.
