## Detailed Description

A directed line segment.

## Constructor & Destructor Documentation

IpeSegment::IpeSegment | ( |  | ) | `[inline]`

| Create default segment.

## Member Function Documentation

IpeLine IpeSegment::Line | ( |  | ) | const`[inline]`

| Return directed line supporting the segment.

double IpeSegment::Distance | ( | const IpeVector & | v,
|  | double | bound
| ) | const

| Returns distance between segment and point v, but may just return bound when its larger than bound.

double IpeSegment::Distance | ( | const IpeVector & | v | ) | const

| Returns distance between segment and point v

bool IpeSegment::Project | ( | const IpeVector & | v,
|  | IpeVector & | projection
| ) | const

| Project point v orthogonally on segment. Returns false if the point falls outside the segment.

bool IpeSegment::Intersects | ( | const IpeSegment & | seg,
|  | IpeVector & | pt
| ) | const

| Compute intersection point. Return `false` if segs don't intersect.

bool IpeSegment::Intersects | ( | const IpeLine & | l,
|  | IpeVector & | pt
| ) | const

| Compute intersection point. Return `false` if no intersection.
