Cut By Line

Cut closed contours into multiple closed contours.

1. Left click to define the cut line starting point

2. Left click again to define the second point of the cut line

3. Any contours that crossed the cut path are divided into separate contours along the cut line

Cut by Line affects contours differently when used on multiple selected contours. When groups of contours are selected, they are automatically grouped into containers and holes. The grouping is respected by the Cut by Line tool. The following images illustrate this concept. When 2 contours are cut without selecting them, 4 contours are created. When the contours are selected before cutting, the hole is respected and 2 contours are created.
