10 years ago Possible scribble UI controls:
left mouse: positive stroke (green) right mouse: negative stroke (red) mouse wheel: change brush size
keyboard: shift/caps lock toggle draw vs erase of each stroke type
keyboard shortcuts select brush type (separately assignable for each of left/right mouse) brush types: circular, snap to region
auto-fill slider bar: selects default UCM threshold for limiting expansion of positive strokes to fill out region
Add scribble support to the current brush-based region creation interface. The scribble interface should be a single-region version (positive/negative strokes) guided by machine-generated Ultrametric Contour Maps (UCMs).
