Module Hugin_gg.P2

Points of the plane.

Types

#type t

The type for points. Coordinates are any floats; a non-finite coordinate is meaningful only where a function says so, as in a path's gaps.

#val v : float -> float -> t

v x y is the point (x, y).

#val x : t -> float

x p is the x coordinate of p.

#val y : t -> float

y p is the y coordinate of p.

#val transform : Affine.t -> t -> t

transform m p is the image of p under m.

#val equal : t -> t -> bool

equal p q is true iff p and q have equal coordinates.

#val compare : t -> t -> int

compare p q orders points by x, then by y.

#val pp : Stdlib.Format.formatter -> t -> unit

pp ppf p formats p as (x, y) for debugging.
