Detailed Description

Sequence of subpaths.

This class corresponds to the SVG notion of a path: a sequence of any number of open or closed contiguous subpaths. Unlike Path, this class is closed under boolean operations.

If you want to represent an arbitrary shape, this is the best class to use. Shapes with a boundary that is composed of only a single contiguous component can be represented with Path instead.

◆ resize()

void Geom::PathVector::resize ( size_type  n)
inline

Change the number of paths.

If the vector size increases, it is passed with paths that contain only a degenerate closing segment at (0,0).

◆ reverse()

void Geom::PathVector::reverse ( bool  reverse_paths = true)

Reverse the direction of paths in the vector.

Parameters
reverse_pathsIf this is true, the order of paths is reversed as well; otherwise each path is reversed, but their order in the PathVector stays the same
