What each control does
Section titled “What each control does”- Density: how many points are thrown per hundred-pixel square of the composition.
- Seed: randomises where points are thrown.
- Size: the diameter of the disc a point is drawn as.
- Feather: how soft that disc’s edge is.
- Colour: what the points are drawn in.
- Max points: the most points.
- Mix: how much of the drawing lands on the picture.
- Matte: this is not a strength. It chooses the alpha the points land inside. Points take that layer’s shape instead of this one’s. Invert reads that matte the other way round, which fills everything the shape does not cover.
