Cubic filters contain a collection of different filters of varying B-Spline and Cardinal values. With these two values you can generate any smoothly fitting (continuious first derivative) piece-wise cubic filter. http://www.imagemagick.org/Usage/filter/#cubic_bc https://www.cs.utexas.edu/~fussell/courses/cs384g-fall2013/lectures/mitchell/Mitchell.pdf

Constructors

CubicResampler(float, float, float)

Initializes a new instance of the CubicResampler struct.

public CubicResampler(float radius, float bspline, float cardinal)

Parameters

radius float

The sampling radius.

bspline float

The B-Spline value.

cardinal float

The Cardinal cubic value.

Fields

CatmullRom

The Catmull-Rom filter is a well known standard Cubic Filter often used as a interpolation function. This filter produces a reasonably sharp edge, but without a the pronounced gradient change on large scale image enlargements that a 'Lagrange' filter can produce.

public static readonly CubicResampler CatmullRom

Field Value

CubicResampler

Hermite

The Hermite filter is type of smoothed triangular interpolation Filter, This filter rounds off strong edges while preserving flat 'color levels' in the original image.
