chromatic_aberration — GFX2D post op

使い方

Scale the red and blue channels about the image centre, green fixed.

Lateral chromatic aberration: red is magnified by 1 + strength, blue by 1 - strength. strength=0 samples the exact pixel centres and returns the input to within 1e-15, which the suite checks.

Negative strength swaps which channel spreads outward — allowed, since which way a real lens disperses depends on the glass.
