Appends the specified matrix properties to this matrix. All parameters are required.
This is the equivalent of multiplying (this matrix) * (specified matrix)
.
This matrix. Useful for chaining method calls.
Generates matrix properties from the specified display object transform properties, and appends them to this matrix. For example, you can use this to generate a matrix representing the transformations of a display object:
var mtx = new createjs.Matrix2D();
mtx.appendTransform(o.x, o.y, o.scaleX, o.scaleY, o.rotation);

Returns a clone of the Matrix2D instance.
a clone of the Matrix2D instance.
Decomposes the matrix into transform properties (x, y, scaleX, scaleY, and rotation). Note that these values may not match the transform properties you used to generate the matrix, though they will produce the same visual results.
The object to apply the transform properties to. If null, then a new object will be returned.
The target, or a new generic object with the transform properties applied.
Returns true if this matrix is equal to the specified matrix (all property values are equal).
The matrix to compare.
Sets the properties of the matrix to those of an identity matrix (one that applies a null transformation).
This matrix. Useful for chaining method calls.
Inverts the matrix, causing it to perform the opposite transformation.
This matrix. Useful for chaining method calls.
Returns true if the matrix is an identity matrix.
Prepends the specified matrix properties to this matrix.
This is the equivalent of multiplying (specified matrix) * (this matrix)

For example, you could calculate the combined transformation for a child object using:
var o = myDisplayObject;
var mtx = o.getMatrix();
while (o = o.parent) {
// prepend each parent's transformation in turn:
o.prependMatrix(o.getMatrix());
}
This matrix. Useful for chaining method calls.
Generates matrix properties from the specified display object transform properties, and prepends them to this matrix. For example, you could calculate the combined transformation for a child object using:
var o = myDisplayObject;
var mtx = new createjs.Matrix2D();
do {
// prepend each parent's transformation in turn:
mtx.prependTransform(o.x, o.y, o.scaleX, o.scaleY, o.rotation, o.skewX, o.skewY, o.regX, o.regY);
} while (o = o.parent);

This matrix. Useful for chaining method calls.
Applies a clockwise rotation transformation to the matrix.
The angle to rotate by, in degrees. To use a value in radians, multiply it by 180/Math.PI
.
This matrix. Useful for chaining method calls.
Applies a scale transformation to the matrix.
The amount to scale horizontally. E.G. a value of 2 will double the size in the X direction, and 0.5 will halve it.
The amount to scale vertically.
This matrix. Useful for chaining method calls.
Sets the specified values on this instance.
Specifies the a property for the new matrix.
Specifies the b property for the new matrix.

a string representation of the instance.
Transforms a point according to this matrix.
The x component of the point to transform.
The y component of the point to transform.
