Description:

 Smooth Midpoint smoothes the geometry of the selected items, keeping segment mid-points fixed. The resulting smooth items will be made up of joined Bezier curves.

The smoothed geometry will go through the midpoints of each segment in the initial geometry, and will also be tangential at these points. If the initial item geometry is not closed, then the smoothed geometry will start and end at the original start and end positions.

Smooth Midpoint changes the existing LineString item consisting of straight LineString item segments into a curved LineString item which touches the original LineString item at the midpoints of its segments.

Example:

1. Select the LineString item to smooth.
   
   
2. Select Smooth Midpoint.
   
   The following action will be carried out:
