Assembly:  System.Drawing (in System.Drawing.dll)

public enum InterpolationMode

Member nameDescription
BicubicSpecifies bicubic interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 25 percent of its original size.
BilinearSpecifies bilinear interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 50 percent of its original size.
DefaultSpecifies default mode.
HighSpecifies high quality interpolation.
HighQualityBicubicSpecifies high-quality, bicubic interpolation. Prefiltering is performed to ensure high-quality shrinking. This mode produces the highest quality transformed images.
HighQualityBilinearSpecifies high-quality, bilinear interpolation. Prefiltering is performed to ensure high-quality shrinking.
InvalidEquivalent to the Invalid element of the QualityMode enumeration.
LowSpecifies low quality interpolation.
NearestNeighborSpecifies nearest-neighbor interpolation.
