Detailed Description

Function Documentation

SplineInterpolateImage()

int SplineInterpolateImage	(	float *	ImageCoeff,
		long	Nx,
		long	Ny,
		double	Xargument,
		double	Yargument,
		double *	Result,
		long	Degree,
		enum TBoundaryConvention	Convention,
		int *	Status
	)

Interpolation 2D. See coments on the 1D interpolation.

SplineInterpolateLine()

int SplineInterpolateLine	(	double	LineCoeff[],
		long	LineLength,
		double	Argument,
		double *	Result,
		long	Degree,
		enum TBoundaryConvention	Convention,
		int *	Status
	)

Interpolation 1D. Interpolation of the 1D array LineCoeff[] of length LineLength. Result = SUM(k): LineCoeff[k] * B-spline(Degree, Argument - k). Convention must be consistent with the B-spline coefficients stored in LineCoeff[]

SplineInterpolateVolume()

int SplineInterpolateVolume	(	float *	VolumeCoeff,
		long	Nx,
		long	Ny,
		long	Nz,
		double	Xargument,
		double	Yargument,
		double	Zargument,
		double *	Result,
