Struct CubicResampler

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_bchttps://www.cs.utexas.edu/~fussell/courses/cs384g-fall2013/lectures/mitchell/Mitchell.pdf

CubicResampler(float, float, float)

Initializes a new instance of the CubicResampler struct.

float bspline

The B-Spline value.
float cardinal

The Cardinal cubic value.

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.

Declaration
public static readonly CubicResampler CatmullRom
Field Value
Type Description
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.

Declaration
public static readonly CubicResampler Hermite
Field Value
Type Description
CubicResampler
