Namespace:  System.Drawing.Drawing2D
Assembly:  System.Drawing (in System.Drawing.dll)

public enum SmoothingMode

Member nameDescription
AntiAliasSpecifies antialiased rendering.
DefaultSpecifies no antialiasing.
HighQualitySpecifies antialiased rendering.
HighSpeedSpecifies no antialiasing.
InvalidSpecifies an invalid mode.
NoneSpecifies no antialiasing.

Default, None, and HighSpeed are equivalent and specify rendering without smoothing applied.

AntiAlias and HighQuality are equivalent and specify rendering with smoothing applied.

NoteNote

When the Graphics.SmoothingMode property is specified by using the SmoothingMode enumeration, it does not affect text. To set the text rendering quality, use the Graphics.TextRenderingHint property and the TextRenderingHint enumeration.

NoteNote

When the Graphics.SmoothingMode property is specified by using the SmoothingMode enumeration, it does not affect areas filled by a path gradient brush. Areas filled by using a PathGradientBrush object are rendered the same way (aliased) regardless of the setting for the Graphics.SmoothingMode property.
