Detailed Description

Models a section of a raw offset curve, starting at a given location along the raw curve. The location is a decimal number, with the integer part containing the segment index and the fractional part giving the fractional distance along the segment. The location of the last section segment is also kept, to allow optimizing joining sections together.

toLine()

static std::unique_ptr< Geometry > geos::operation::buffer::OffsetCurveSection::toLine ( std::vector< std::unique_ptr< OffsetCurveSection > > &  sections, const GeometryFactory *  geomFactory  )

static

Joins section coordinates into a LineString. Join vertices which lie in the same raw curve segment are removed, to simplify the result linework.

Parameters

sections	the sections to join
geomFactory	the geometry factory to use

Returns

the simplified linestring for the joined sections
