Namespace:  System.Drawing.Drawing2D
Assembly:  System.Drawing (in System.Drawing.dll)

public enum InterpolationMode

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