Automatic Gap Closing

Thanks to the MapKernel library, we:

• compute the planar map, i.e. the zones defined by all the strokes,
• edit this planar map, adding, cutting or removing edges,
• read back a planar geometry in terms of Bézier curves.

We use the central trajectory of strokes to compute the planar map for three reasons:

• the size of the map is smaller (twice),
• the width of the strokes may have to be changed when the drawing is reused,
• we want to avoid artifacts that arise when two zones are exactly adjacent.
