InterpolationMode Enumeration

The InterpolationMode enumeration specifies the algorithm that is used when images are scaled or rotated. This enumeration is used by the Graphics::GetInterpolationMode and Graphics::SetInterpolationMode methods of the Graphics class.

Syntax

typedef enum InterpolationMode {
  InterpolationModeInvalid              ,
  InterpolationModeDefault              ,
  InterpolationModeLowQuality           ,
  InterpolationModeHighQuality          ,
  InterpolationModeBilinear             ,
  InterpolationModeBicubic              ,
  InterpolationModeNearestNeighbor      ,
  InterpolationModeHighQualityBilinear  ,
  InterpolationModeHighQualityBicubic
} ;

Constants

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.
