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

CubicResampler(float, float, float)

Initializes a new instance of the CubicResampler struct.

Declaration

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

Parameters

Type	Name	Description
float	radius	The sampling radius.
float	bspline	The B-Spline value.
float	cardinal	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.

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
