The SmoothingMode enumeration specifies the type of smoothing (antialiasing) that is applied to lines and curves. This enumeration is used by the GdipGetSmoothingMode and GdipSetSmoothingMode functions.

 

C++ Syntax

 

typedef enum {

SmoothingModeInvalid = QualityModeInvalid,

SmoothingModeDefault = QualityModeDefault,

SmoothingModeHighSpeed = QualityModeLow,

SmoothingModeHighQuality = QualityModeHigh,

SmoothingModeNone,

SmoothingModeAntiAlias8x4,

SmoothingModeAntiAlias = SmoothingModeAntiAlias8x4,

SmoothingModeAntiAlias8x8

} SmoothingMode;

SmoothingModeInvalid = QualityModeInvalid

SmoothingModeNone = 3

end enum

 

常数

 

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.

 

SmoothingModeAntiAlias8x4

 

Specifies that smoothing is applied using an 8 X 4 box filter.

 

SmoothingModeAntiAlias

 

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.

 

备注

 

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.
