Module Mlpost.Transform
Apply linear transformations to objects in Mlpost
val scaled : Num.t -> t'
Scale an object by a constant factor.
- parameter scale
a scaling function to be applied to each float; see
Num.t
for scaling functions for usual units. This makes only sense when the object to be transformed is given in "bp" units
val rotated : float -> t'
Scale an object by a constant factor.
- parameter scale
a scaling function to be applied to each float; see
Num.t
for scaling functions for usual units. This makes only sense when the object to be transformed is given in "bp" units
Rotate an object by an angle given in degrees
val shifted : Point.t -> t'
Rotate an object by an angle given in degrees
Shift an object with respect to a point
val slanted : Num.t -> t'
Shift an object with respect to a point
Slant an object: the point
(x,y)
becomes(x+ay,y)
, with slanting factora
val xscaled : Num.t -> t'
Slant an object: the point
(x,y)
becomes(x+ay,y)
, with slanting factora
Scale an object by a constant factor, but only in the
x
direction
val yscaled : Num.t -> t'
Scale an object by a constant factor, but only in the
x
directionScale an object by a constant factor, but only in the
y
direction
val zscaled : Point.t -> t'
Scale an object by a constant factor, but only in the
y
directionZscaled multiplies points of the object by the given point, using "complex" multiplication:
(x,y) * (a,b) = (ax - by, bx + ay)
; its effect is to rotate and scale so as to map(1,0)
into(a,b)
val reflect : Point.t -> Point.t -> t'
Zscaled multiplies points of the object by the given point, using "complex" multiplication:
(x,y) * (a,b) = (ax - by, bx + ay)
; its effect is to rotate and scale so as to map(1,0)
into(a,b)
Reflect an object with respect to the line that goes through the two given points
val rotate_around : Point.t -> float -> t'
Reflect an object with respect to the line that goes through the two given points
Rotate an object by an angle given in degrees, around a given point
type matrix
= Ctypes.matrix
type t
= t' list
A transformation is a list of single transformations
val id : t
The identity transformation
