Capture

In some situations, for example, in the restrict function, the user is allowed to identify drawing information that lies inside (or outside) a rectangle, a polygon or a general area, built up by contours. This facility will throughout this manual be referred to as "CAPTURE" and the geometry identified in this fashion will be called "captured geometry". As default, any kind of geometry will be captured but the user has the opportunity to specify exactly what kind of geometry to capture (for example, points, texts )
