[Lib2geom-devel] Subpath from path by length?

[mathog <ma...@ca...>]

How in 2geom does one do (pseudocode)

Geom::Path P;  //contains a path already, lines and/or Beziers

Geom::Point from=P.begin();
subpath = make_sub_path(P,from,start,end,&trunc);

where:

1. subpath is the path: from + start -> from + end, where start & end 
are distances along P
2. trunc is set if the subpath would have extended beyond P.end().

The original path P should not be modified.

Thanks,
