stipple_energy — PRINTPATH stroke op

• Data kinds: image2d × pairs → measurement

• Call: import fullseye as fs; fs.ledger.stipple_energy(image, points, gamma=1.0, floor=0.02) (to call the implementation directly, import printpath; printpath.stipple_energy(image, points, gamma=1.0, floor=0.02); from the registry, opsprintpath.get("stipple_energy"))
