Description

TCustomKernel serves as the abstract base class for all spatial interpolation filter kernels in Graphics32. It defines the standard mathematical interface for evaluating 1D kernel weights ($f(x)$) and determining the kernel's spatial radius ($W$).

Descendant kernel classes implement specific mathematical functions such as Box, Linear, Cosine, Cubic, B-Spline, Gaussian, and Windowed Sinc filters.
