InterpolationMode enumeration
Applies to: desktop apps only
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 {
InterpolationModeInvalid = QualityModeInvalid,
InterpolationModeDefault = QualityModeDefault,
InterpolationModeLowQuality = QualityModeLow,
InterpolationModeHighQuality = QualityModeHigh,
InterpolationModeBilinear = QualityModeHigh + 1,
InterpolationModeBicubic = QualityModeHigh + 2,
InterpolationModeNearestNeighbor = QualityModeHigh + 3,
InterpolationModeHighQualityBilinear = QualityModeHigh + 4,
InterpolationModeHighQualityBicubic = QualityModeHigh + 5
} InterpolationMode;
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.
