LanczosWarpingKernel
: public lsst::afw::math::SeparableKernel¶ Lanczos warping: accurate but slow and can introduce ringing artifacts.
This kernel is the product of two 1-dimensional Lanczos functions. The number of minima and maxima in the 1-dimensional Lanczos function is 2*order + 1. The kernel has one pixel per function minimum or maximum; but as applied to warping, the first or last pixel is always zero and can be omitted. Thus the kernel size is 2*order x 2*order.
