Transformation

Represents an affine transformation: a set of coefficients a, b, c, d for transforming a point of a form (x, y) into (a*x + b, c*y + d) and doing the reverse. Used by Leaflet in its projections code.

Usage example

const transformation = new Transformation(2, 5, -1, 10),
p = new Point(1, 2),
p2 = transformation.transform(p), //  new Point(7, 8)
p3 = transformation.untransform(p2); //  new Point(1, 2)
