The InterpolationMode enumeration specifies the algorithm that is used when images are scaled or rotated. This enumeration is used by the GdipGetInterpolationMode and GdipSetInterpolationMode functions of the Graphics functions.

常数

 

InterpolationModeInvalid

 

Used internally.

 

InterpolationModeDefault

 

Specifies the default interpolation mode.

 

InterpolationModeLowQuality

 

Specifies a low-quality mode.

 

InterpolationModeHighQuality

 

Specifies a high-quality mode.

 

InterpolationModeBilinear

 

Specifies bilinear interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 50 percent of its original size.

 

InterpolationModeBicubic

 

Specifies bicubic interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 25 percent of its original size.

 

InterpolationModeNearestNeighbor

 

Specifies nearest-neighbor interpolation.

 

InterpolationModeHighQualityBilinear

 

Specifies high-quality, bilinear interpolation. Prefiltering is performed to ensure high-quality shrinking.

 

InterpolationModeHighQualityBicubic

 

Specifies high-quality, bicubic interpolation. Prefiltering is performed to ensure high-quality shrinking. This mode produces the highest quality transformed images.
