Syntax

Delphi:

type TGPInterpolationMode = (InterpolationModeInvalid, Ord, QualityModeInvalid, InterpolationModeDefault, Ord, QualityModeDefault, InterpolationModeLowQuality, Ord, QualityModeLow, InterpolationModeHighQuality, Ord, QualityModeHigh, InterpolationModeBilinear, InterpolationModeBicubic, InterpolationModeNearestNeighbor, InterpolationModeHighQualityBilinear, InterpolationModeHighQualityBicubic);

C++ Builder:

enum TGPInterpolationMode {InterpolationModeInvalid, Ord, QualityModeInvalid, InterpolationModeDefault, Ord, QualityModeDefault, InterpolationModeLowQuality, Ord, QualityModeLow, InterpolationModeHighQuality, Ord, QualityModeHigh, InterpolationModeBilinear, InterpolationModeBicubic, InterpolationModeNearestNeighbor, InterpolationModeHighQualityBilinear, InterpolationModeHighQualityBicubic};

Visual C++ (MFC):

enum CTGPInterpolationMode {InterpolationModeInvalid, Ord, QualityModeInvalid, InterpolationModeDefault, Ord, QualityModeDefault, InterpolationModeLowQuality, Ord, QualityModeLow, InterpolationModeHighQuality, Ord, QualityModeHigh, InterpolationModeBilinear, InterpolationModeBicubic, InterpolationModeNearestNeighbor, InterpolationModeHighQualityBilinear, InterpolationModeHighQualityBicubic};

Summary

Specifies the algorithm that is used when images are scaled or rotated.

Description

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

Values

InterpolationModeInvalid Used internally.
Ord
QualityModeInvalid
InterpolationModeDefault Specifies the default interpolation mode.
Ord
QualityModeDefault
InterpolationModeLowQuality Specifies a low-quality mode.
Ord
QualityModeLow
InterpolationModeHighQuality Specifies a high-quality mode.
Ord
QualityModeHigh
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.
