Transformpoint (Matrix.transformpoint Method) - MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE Reference

Example
The following example creates and converts its values to a string in the format of
myMatrix
(a=A, b=B, c=C, d=D, tx=TX, ty=TY).
import flash.geom.Matrix;
var myMatrix:Matrix = new Matrix();
trace("myMatrix: " + myMatrix.toString()); // (a=1, b=0, c=0, d=1, tx=0,
ty=0)

transformPoint (Matrix.transformPoint method)

public transformPoint(pt:Point) : Point
Applies the geometric transformation represented by the Matrix object to the specified point.
Availability: ActionScript 1.0; Flash Player 8
Parameters
- The Point (x,y) to be transformed.
pt:flash.geom.Point
Returns
- The new Point object.
flash.geom.Point
Example
The following example uses the method to create
transformPoint() transformedPoint
from . The method does have an affect on the position of
myPoint translate()
. In the example, increases the original value by a factor of
transformedPoint scale() x
three from 50 to 150, and the method increases by 300 for a total value of
translate() x
450.
import flash.geom.Matrix;
import flash.geom.Point;
var myMatrix:Matrix = new Matrix();
trace(myMatrix); // (a=1, b=0, c=0, d=1, tx=0, ty=0)
myMatrix.translate(100, 0);
trace(myMatrix); // (a=1, b=0, c=0, d=1, tx=100, ty=0)
myMatrix.scale(3, 3);
trace(myMatrix); // (a=3, b=0, c=0, d=3, tx=300, ty=0)
var myPoint:Point = new Point(50,0);
trace(myPoint); // (50, 0)
