Interpolation methods

Some of the code to perform interpolation in Fourier space as been adapted from GalSim-developers/JAX-GalSim GalSim-developers/JAX-GalSim

Classes

Interpolant(extent)	Base class for interpolants
Lanczos(n)	Lanczos interpolation class
Quintic()	Quintic interpolation from Gruen & Bernstein (2014)

Functions

resample2d(signal, coords, warp[, interpolant])	Resample a 2-dimensional image using a Lanczos kernel
resample3d(signal, coords, warp, interpolant)	Resample a 3-dimensional image using a Lanczos kernel
resample_fourier(kimage, shape_in, shape_out)	Resampling operation
resample_hermitian(signal, warp, x_min, y_min)	Resample a 2-dimensional image using an interpolation kernel
