Function perpendicularPoint

Returns a point perpendicular to line at a specified distance. Use negative distances for the other side of line.

import { Lines } from 'https://unpkg.com/ixfx/dist/geometry.js'
// Project a point 100 units away from line, at its midpoint.
const pt = Lines.perpendicularPoint(line, 100, 0.5);

x: number;
y: number;
}
Parameters
- line: Line
  Line
- distance: number
  Distance from line. Use negatives to flip side
- amount: number = 0
  Relative place on line to project point from. 0 projects from A, 0.5 from the middle, 1 from B.
