▶Help / Legend

Click a vessel segment to mark it as collateral (click again to remove). Every click leaves a red dot marking its coordinate; clicking background (no vessel) also leaves a red dot — click near an existing red dot to delete it. Zoom: wheel/pinch; pan: left-drag/two-finger. Colors: vessel mask = bright blue, selected = green, hover = orange, red dot = click location.

Annotation tool

Magnetic snap (grab nearest vessel)

Off: click exactly on a segment to select it. On: a click near a vessel snaps onto the nearest one.

Radius8

Left-drag to select every segment the brush touches (uses the active class); pan with wheel/two-finger, or hold Space + left-drag.

Radius6

Left-drag = paint (uses the active class’s color); pan with wheel/two-finger, or hold Space + left-drag.
