EmfPlusFilterType

EmfPlusFilterType enumeration

The FilterType enumeration defines types of filtering algorithms that can be used for text and graphics quality enhancement and image rendering.

public enum EmfPlusFilterType : byte

Values

NameValueDescription
FilterTypeNone0Specifies that filtering is not performed.
FilterTypePoint1Specifies that each destination pixel is computed by sampling the nearest pixel from the source image.
FilterTypeLinear2Specifies that linear interpolation is performed using the weighted average of a 2x2 area of pixels surrounding the source pixel.
FilterTypeTriangle3Specifies that each pixel in the source image contributes equally to the destination image. This is the slowest of filtering algorithms.
FilterTypeBox4Specifies a box filter algorithm, in which each destination pixel is computed by averaging a rectangle of source pixels. This algorithm is useful only when reducing the size of an image.
FilterTypePyramidalQuad6Specifies that a 4-sample tent filter is used.
FilterTypeGaussianQuad7Specifies that a 4-sample Gaussian filter is used, which creates a blur effect on an image.
