                              RhumbLine

Compute one or several points on a single rhumb line.

Class RhumbLine facilitates the determination of points on a single rhumb line. The starting point (`lat1`, `lon1`) and the azimuth `azi12` are specified once.

Method RhumbLine.Position returns the location of an other point and optionally the distance `s12` along the corresponding area `S12` under the rhumb line.

Method RhumbLine.intersection2 finds the intersection between two rhumb lines.

Method RhumbLine.nearestOn4 computes the nearest point on and its distance to a rhumb line.

Method Details

### __init__ (self, rhumb, lat1=0, lon1=0, azi12=None, caps=0, name='') (Constructor) |
New RhumbLine. Arguments: `rhumb` - The rhumb reference (Rhumb). `lat1` - Latitude of the start point (`degrees90`). `lon1` - Longitude of the start point (`degrees180`). `azi12` - Azimuth of this rhumb line (compass `degrees`). `caps` - Bit-or'ed combination of Caps values specifying the capabilities. Include `Caps.LINE_OFF` if updates to `rhumb` should not be reflected in this rhumb line. `name` - Optional name (`str`). Overrides: object.__init__
