InterpolationMode Enumeration

The InterpolationMode enumeration specifies the algorithm that is used when images are scaled or rotated.

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

Syntax

Visual Basic (Declaration)

Public Enumeration InterpolationMode

Visual Basic (Usage)

Dim instance As InterpolationMode

public enum InterpolationMode

Visual C++

public enum class InterpolationMode

JScript

public enum InterpolationMode

Members

	Member name	Description
	Invalid	Equivalent to the Invalid element of the QualityMode enumeration.
	Default	Specifies default mode.
	Low	Specifies low quality interpolation.
	High	Specifies high quality interpolation.
	Bilinear	Specifies bilinear interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 50 percent of its original size.
	Bicubic	Specifies bicubic interpolation. No prefiltering is done. This mode is not suitable for shrinking an image below 25 percent of its original size.
	NearestNeighbor	Specifies nearest-neighbor interpolation.
	HighQualityBilinear	Specifies high-quality, bilinear interpolation. Prefiltering is performed to ensure high-quality shrinking.
	HighQualityBicubic	Specifies high-quality, bicubic interpolation. Prefiltering is performed to ensure high-quality shrinking. This mode produces the highest quality transformed images.
