Library has an issue with breaking paths at intersection points. Function is called Dissolve.

In my case I use this lab for .gpx files. And to get around this issue I use GDAL ogr2ogr operation. The command call looks like this:

ogr2ogr -nlt MULTILINESTRING -dsco GPXUSEEXTENSIONS=YES -lco FORCEGPXTRACK=YES -f GPX "%output%" "%input%" -dialect sqlite -sql "select ST_union(Geometry) from tracks"

Here %input% is an input gpx file and %output% - output gpx file.

After performing this operation outline calculation works like a charm.
