var myMatrix = new air.Matrix();

var degrees = 30;
var radians = (degrees/180) * Math.PI;

The distance by which to translate each point along the x axis.

var myMatrix = new air.Matrix();

myMatrix.tx = 50;  // 50
air.trace(myMatrix.tx);

Creates a new Matrix object with the specified parameters. In matrix notation, the properties are organized like this:

If you do not provide any parameters to the new Matrix() constructor, it creates an identity matrix with the following values:

a = 1

b = 0

c = 0

d = 1

tx = 0

ty = 0

In matrix notation, the identity matrix looks like this:

var matrix_1 = new air.Matrix();
air.trace(matrix_1);  // (a=1, b=0, c=0, d=1, tx=0, ty=0)

var matrix_2 = new air.Matrix(1, 2, 3, 4, 5, 6);
air.trace(matrix_2);  // (a=1, b=2, c=3, d=4, tx=5, ty=6)

Returns a new Matrix object that is a clone of this matrix, with an exact copy of the contained object.

Concatenates a matrix with the current matrix, effectively combining the geometric effects of the two. In mathematical terms, concatenating two matrixes is the same as combining them using matrix multiplication.

For example, if matrix m1 scales an object by a factor of four, and matrix m2 rotates an object by 1.5707963267949 radians (Math.PI/2), then m1.concat(m2) transforms m1 into a matrix that scales an object by a factor of four and rotates the object by Math.PI/2 radians.

This method replaces the source matrix with the concatenated matrix. If you want to concatenate two matrixes without altering either of the two source matrixes, first copy the source matrix by using the clone() method, as shown in the Class Examples section.

Parameters

Copies a Vector3D object into specific column of the calling Matrix3D object.

Parameters

Copies specific column of the calling Matrix object into the Vector3D object. The w element of the Vector3D object will not be changed.

Parameters

Copies all of the matrix data from the source Point object into the calling Matrix object.

Parameters

Copies a Vector3D object into specific row of the calling Matrix object.

Parameters

Copies specific row of the calling Matrix object into the Vector3D object. The w element of the Vector3D object will not be changed.

Parameters

Includes parameters for scaling, rotation, and translation. When applied to a matrix it sets the matrix's values based on those parameters.

Using the createBox() method lets you obtain the same matrix as you would if you applied the identity(), rotate(), scale(), and translate() methods in succession. For example, mat1.createBox(2,2,Math.PI/4, 100, 100) has the same effect as the following:

     var mat1 = new air.Matrix();

     mat1.identity();

     mat1.rotate(Math.PI/4);

     mat1.scale(2, 2);

     mat1.translate(10, 20);

     

Parameters

Creates the specific style of matrix expected by the beginGradientFill() and lineGradientStyle() methods of the Graphics class. Width and height are scaled to a scaleX/scaleY pair and the tx/ty values are offset by half the width and height.

For example, consider a gradient with the following characteristics:

• GradientType.LINEAR
• Two colors, green and blue, with the ratios array set to [0, 255]
• SpreadMethod.PAD
• InterpolationMethod.LINEAR_RGB

The following illustrations show gradients in which the matrix was defined using the createGradientBox() method with different parameter settings:

createGradientBox() settings	Resulting gradient
width = 25; height = 25; rotation = 0; tx = 0; ty = 0;
width = 25; height = 25; rotation = 0; tx = 25; ty = 0;
width = 50; height = 50; rotation = 0; tx = 0; ty = 0;
width = 50; height = 50; rotation = Math.PI / 4; // 45 degrees tx = 0; ty = 0;

Parameters

Given a point in the pretransform coordinate space, returns the coordinates of that point after the transformation occurs. Unlike the standard transformation applied using the transformPoint() method, the deltaTransformPoint() method's transformation does not consider the translation parameters tx and ty.

Parameters

Sets each matrix property to a value that causes a null transformation. An object transformed by applying an identity matrix will be identical to the original.

After calling the identity() method, the resulting matrix has the following properties: a=1, b=0, c=0, d=1, tx=0, ty=0.

In matrix notation, the identity matrix looks like this:

Performs the opposite transformation of the original matrix. You can apply an inverted matrix to an object to undo the transformation performed when applying the original matrix.

Applies a rotation transformation to the Matrix object.

The rotate() method alters the a, b, c, and d properties of the Matrix object. In matrix notation, this is the same as concatenating the current matrix with the following:

Parameters

Applies a scaling transformation to the matrix. The x axis is multiplied by sx, and the y axis it is multiplied by sy.

The scale() method alters the a and d properties of the Matrix object. In matrix notation, this is the same as concatenating the current matrix with the following matrix:

Parameters

Sets the members of Matrix to the specified values

Parameters

Returns a text value listing the properties of the Matrix object.

Returns the result of applying the geometric transformation represented by the Matrix object to the specified point.

Parameters

Translates the matrix along the x and y axes, as specified by the dx and dy parameters.
