Features

Clipping

Clipping allows you to perform boolean operations (AND, OR, NOT & XOR) on poligons.

• AND (Intersection) - create regions where both subject and clip polygons are filled;
• OR (Union) - create regions where either subject or clip polygons (or both) are filled;
• NOT (Difference) - create regions where subject polygons are filled except where clip polygons are filled;
• XOR (Exclusive or) - create regions where either subject or clip polygons are filled but not where both are filled.

Offsetting

Offsetting is the process of inflating/deflating both open and closed paths using a number of different join types and end types.
