Mask tools
DrawoverSince 1.0
Overview
A real layer mask: strokes apply in order onto an alpha channel rather than each punching a permanent hole, which is what makes erase-then-restore work.
The typical job is putting something behind something else. Lay a mountain reference over the plate, erase it across the trees, and the plate's trees come back through — the mountain now sits behind them. Nick an edge, and the restore brush paints that patch of reference back instead of forcing you to start the mask over.
How to
- Select the reference layer (or just click it with a mask tool).
- Erase reference — brush the reference away; the daily shows through.
- Restore reference — paint it back where you over-erased.
- Lasso erase / Lasso keep for fast area work.

Known edges
Masking is non-destructive and per-layer. The tools grey out until the frame has a reference image on it.
