| int dig_build_area_with_line | ( | struct Plus_head * | plus, |

| ) |
Build topo for area from lines.
Area is built in clockwise order. Take a given line and start off to the RIGHT/LEFT and try to complete an area.
Possible Scenarios:
- I. path runs into first line. : AREA!
- II. path runs into a dead end (no other area lines at node) : no area
- III. path runs into a previous line that is not 1st line or to 1st line but not to start node : no area
After we find an area then we call point_in_area() to see if the specified point is w/in the area
Old returns -1: error 0: no area (1: point in area) -2: island !!
- Parameters
-
[in] plus pointer to Plus_head structure [in] first_line line id of first line [in] side side of line to build area on (GV_LEFT | GV_RIGHT) [in] lines pointer to array of lines
- Returns
- -1 on error
- 0 no area
- number of lines

◆ dig_del_area()
Delete area from Plus_head structure.
This function deletes area from the topo structure and resets references to this area in boundaries, isles (within), and the centroid (if any) to 0. Possible new area is not created by this function, so that old boundaries participating in this area are left without area information even if form new area. Not enabled now: If area is inside other area, area info for islands within deleted area is reset to that area outside. (currently area info of isles is set to 0)
- Parameters
-
[in] plus pointer to Plus_head structure [in] area area id
- Returns
- 0 on error
- 1 on success
