Overview
This class provides static functions to perform rotating, scaling, shearing,
and translation transformations for Affine
objects.
Example:
Rectangle {
width: 50
height: 50
fill:Color.RED
transform: Transform.rotate(45,0,0); //rotate by 45 degress
}

Function Summary
- public static affine(m00: Number, m01: Number, m02: Number, m10: Number, m11: Number, m12: Number) : Affine
-
Returns a new

object from 6 number values representing the 6 specifiable entries of the 3x3 transformation matrix.Returns a new
Affine
object from 6 number values representing the 6 specifiable entries of the 3x3 transformation matrix.-
Parameters
- m00
- the X coordinate scaling element of the 3x3 matrix
- m01
- the Y coordinate shearing element of the 3x3 matrix
- m02
- the X coordinate shearing element of the 3x3 matrix
- m10
- the Y coordinate scaling element of the 3x3 matrix
- m11
- the X coordinate translation element of the 3x3 matrix
- m12
- the Y coordinate translation element of the 3x3 matrix
-
Returns
- Affine
-

- public static rotate(angle: Number, x: Number, y: Number) : Rotate
-
Returns a
More: [+]Rotate
object that rotates coordinates around an anchor point.Returns a
Rotate
object that rotates coordinates around an anchor point. This operation is equivalent to translating the coordinates so that the anchor point is at the origin (S1), then rotating them about the new origin (S2), and finally translating so that the intermediate origin is restored to the coordinates of the original anchor point (S3).The matrix representing the returned transform is:
[ cos(theta) -sin(theta) x-x*cos+y*sin ] [ sin(theta) cos(theta) y-x*sin-y*cos ] [ 0 0 1 ]
Rotating by a positive angle theta rotates points on the positive X axis toward the positive Y axis.-
Parameters
- angle
- the angle of rotation measured in radians
- x
- the X coordinate of the rotation anchor point
- y
- the Y coordinate of the rotation anchor point
-
Returns
- Rotate
-
a
Rotate
object that rotates coordinates around the specified point by the specified angle of rotation.
Profile: common
- public static scale(x: Number, y: Number) : Scale
-
Returns a
More: [+]Scale
object representing a scaling transformation.Returns a
Scale
object representing a scaling transformation.The matrix representing the returned transform is:

-
Returns
- Scale
- an <code>AffineTransform</code> object that scales coordinates by the specified factors.
Profile: common
- public static shear(x: Number, y: Number) : Shear
-
Returns a
More: [+]Shear
object representing a shearing transformation.Returns a
Shear
object representing a shearing transformation.The matrix representing the returned transform is:
