Cleaning Points

Imported line art often carries far more points than it needs — a Grease Pencil stroke can be hundreds of micro-segments. The point sliders in the Stroke Thickness card clean that up without changing the line's shape. Turn on the Points overlay to watch the anchors thin out live.

Simplify Points

Simplify decimates redundant anchors using a corner-aware Schneider bézier fit — it removes points on straight or gently-curving stretches and keeps the ones that carry the shape. More Simplify = fewer anchors and a lighter, more hand-editable stroke in Harmony.

Shape stays, points go

Simplify never moves the line off its path — it re-fits the same curve with fewer control points. The pressure keys ride along, re-labelled onto the new geometry.

Relax Points

Relax is a gentle global denoise — it nudges each point toward the mean of its neighbours without removing any. Use it to take the jitter out of a shaky traced or hand-drawn line before Simplify decimates it.

• Simplify changes the number of points.
• Relax changes their position (smooths noise), keeping the count.

They stack: Relax first (de-noise), then Simplify (decimate), then the global smoothing on top.

Corners

Corners controls how sharp a corner has to be to survive the smoothing. High Corners = keep sharp corners sharp while the rest rounds out; low Corners = let everything round. It feeds the Schneider fit's corner-angle threshold, so a character's crisp chin stays crisp while soft curves stay soft.

A typical cleanup

1. Relax a little to settle a noisy source.
2. Simplify until the anchor count looks hand-drawn.
3. Corners up if a sharp feature is getting rounded off.

Prefer the brushes for local cleanup

The sliders are global — they affect the whole stroke set. When you only want to relax or simplify one region (a messy hand, a busy hairline), use the Weight-Paint Brushes to paint the effect exactly where it's needed.
