SmoothingMode enumeration (gdiplusenums.h)

The SmoothingMode enumeration specifies the type of smoothing (antialiasing) that is applied to lines and curves. This enumeration is used by the Graphics::GetSmoothingMode and Graphics::SetSmoothingMode methods of the Graphics class.

Syntax

typedef enum SmoothingMode {
  SmoothingModeInvalid,
  SmoothingModeDefault,
  SmoothingModeHighSpeed,
  SmoothingModeHighQuality,
  SmoothingModeNone,
  SmoothingModeAntiAlias,
  SmoothingModeAntiAlias8x4,
  SmoothingModeAntiAlias8x8
} ;

Constants

SmoothingModeInvalid Reserved.
SmoothingModeDefault Specifies that smoothing is not applied.
SmoothingModeHighSpeed Specifies that smoothing is not applied.
SmoothingModeHighQuality Specifies that smoothing is applied using an 8 X 4 box filter.
SmoothingModeNone Specifies that smoothing is not applied.
SmoothingModeAntiAlias Specifies that smoothing is applied using an 8 X 4 box filter.
SmoothingModeAntiAlias8x4 Specifies that smoothing is applied using an 8 X 4 box filter.
SmoothingModeAntiAlias8x8 Specifies that smoothing is applied using an 8 X 8 box filter.

Remarks

Smoothing performed by an 8 X 4 box filter gives better results for nearly vertical lines than it does for nearly horizontal lines. Smoothing performed by an 8 X 8 box filter gives equally good results for nearly vertical and nearly horizontal lines. The 8x8 algorithm produces higher quality smoothing but is slower than the 8 X 4 algorithm.
