System information

The individual elements that make up a path are called segments. Sometimes a path can be just
one segment, but it can also consist of multiple segments.

Anchor points
If you draw a line —or a segment— on a piece of paper, you start at a given point, i.e. where you
put your pencil on the paper, and you stop at another point, where you remove the pencil from the
paper. In line art, these points are called anchor points. Logically, if you move these anchor points,
you will change the path segment and perhaps the shape of the path.
Figure 24: Anchor points (A, B and C) define the beginning and the end of each segment.
Direction points
Curved segments have, beside their anchor points, two additional points of control, called direction
points. These direction points are attached to the anchor points of a curved segment by means of
direction lines. If you move any of these direction points, you will change the shape of the curve.
