control point
The
points that define a path. Line segments and gaps have two control
points, at the start and end, cubic Bézier segments have four
control points: one at the start of the segment, one at the end of
the segment, and two others that define the curvature of the segment.
Adjacent segments share a common control point. When a path is under
construction, or is being edited, the control points are shown as
orange or red squares. Composite paths also have control points that
govern how the full path is created from the underlying shape. The
composite control points are coloured differently to the standard
path controls.
