GetLineDistance()
Summary
Finds the distance from a coordinate to a line.
Syntax
dist = GetLineDistance(coord c, array shape_pts)
| Argument | Contents |
|---|---|
| c | The coordinate |
| shape_pts | The array of shape points in the line |
Returns
An array of three elements:
| Element | Type | Contents |
|---|---|---|
| 1 | Real | The distance to the closest line segment |
| 2 | Coord | The coordinate on the segment that is closest to the point |
| 3 | Integer | The index of the shape point in the array that forms the beginning of the closest line segment (1 <= index < shape_pts.length) |
Notes
-
Use GetLine() to get the array of shape points in the line.
