Gradients (off unless asked for) found a blurred or noisy linear gradient in part or in pieces, with bands around it. The areas that may be a gradient are tried largest first, and one that is a gradient is grown over every pixel next to it whose colour is within 10 levels of the gradient's there: the pixels noise put a little off, a soft rim, the pieces noise cut off it. Linear-gradient inputs with Gradients on, paths beside the gradient, before -> after: blurred 3.0 -> 0.5 (6 Colors) and 55.5 -> 0.5 (High Fidelity Photo); noisy 11.0 -> 0.5 and 23.5 -> 1.5; scanned 5.5 -> 3.0 and 46.5 -> 37.0; clean and aliased as before; dE within 0.02. No gradient on any input that is flat colour, with any preset (the harness fails if there is one).
