| convertTo3D | () | method |
public static function convertTo3D(matrix:Matrix, resultMatrix:Matrix3D = null):Matrix3DConverts a 2D matrix to a 3D matrix. If you pass a 'resultMatrix', the result will be stored in this matrix instead of creating a new object.
Parameters
matrix:Matrix | |
resultMatrix:Matrix3D (default = null) |
Matrix3D |
| prependMatrix | () | method |
public static function prependMatrix(base:Matrix, prep:Matrix):voidPrepends a matrix to 'base' by multiplying it with another matrix.
Parameters
base:Matrix | |
prep:Matrix |
| prependRotation | () | method |
public static function prependRotation(matrix:Matrix, angle:Number):voidPrepends an incremental rotation to a Matrix object (angle in radians).
Parameters
matrix:Matrix | |
angle:Number |
| prependScale | () | method |
public static function prependScale(matrix:Matrix, sx:Number, sy:Number):voidPrepends an incremental scale change to a Matrix object.
Parameters

| prependSkew | () | method |
public static function prependSkew(matrix:Matrix, skewX:Number, skewY:Number):voidPrepends a skew transformation to a Matrix object (angles in radians). The skew matrix has the following form:
| cos(skewY) -sin(skewX) 0 |
| sin(skewY) cos(skewX) 0 |
| 0 0 1 |
Parameters
matrix:Matrix | |
skewX:Number | |

tx:Number | |
ty:Number |
| skew | () | method |
public static function skew(matrix:Matrix, skewX:Number, skewY:Number):voidAppends a skew transformation to a matrix (angles in radians). The skew matrix has the following form:
| cos(skewY) -sin(skewX) 0 |
| sin(skewY) cos(skewX) 0 |
| 0 0 1 |
Parameters
matrix:Matrix | |
skewX:Number | |
skewY:Number |
| transformCoords | () | method |
public static function transformCoords(matrix:Matrix, x:Number, y:Number, resultPoint:Point = null):PointUses a matrix to transform 2D coordinates into a different space. If you pass a 'resultPoint', the result will be stored in this point instead of creating a new object.
