sobelTaps
Eight brightness samples in a ring around each pixel, for finding edges.
sobelTaps(slots: {spacing: PropRef}): SobelRing
Import effects from shaders/std and use effects.stylize.sobelTaps.
spacing is the distance to the ring in device pixels (about 0.5 to 4; thicker strokes at larger values). Returns the ring for chalkSketch.
Parameters
