color_grade — GFX2D post op

使い方

Apply a 3-D colour LUT to an rgb image by trilinear interpolation.

lut is (n, n, n, 3) indexed [r, g, b] — the layout :func:color_lut produces. The identity LUT returns the input to within float64 rounding (measured maximum 3.3e-16), which is what makes this testable without a reference implementation: trilinear interpolation of a coordinate function is that coordinate, exactly.
