SVG matrix interface
Many of SVG's graphics operations utilize 2x3 matrices of the form:
[a c e] [b d f]
which, when expanded into a 3x3 matrix for the purposes of matrix arithmetic, become:
[a c e] [b d f] [0 0 1]
An SVGMatrix
object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.

Properties
Name  Type  Description 

a 
float  The a component of the matrix. 
b 
float  The b component of the matrix. 
c 
float  The c component of the matrix. 
d 
float  The d component of the matrix. 
e 
float  The e component of the matrix. 
f 
float  The f component of the matrix. 
a DOMException
with code NO_MODIFICATION_ALLOWED_ERR
is raised when attempting updating a read only attribute or when the object itself is read only.
Methods
Name & Arguments  Return  Description 

multiply(in 
SVGMatrix 
Performs matrix multiplication. This matrix is postmultiplied by another matrix, returning the resulting new matrix. 
inverse() 
SVGMatrix 
Return the inverse matrix Exceptions:

translate(in float x, in float y) 
SVGMatrix 
Postmultiplies a translation transformation on the current matrix and returns the resulting matrix.

scale(in float scaleFactor) 
SVGMatrix 
Postmultiplies a uniform scale transformation on the current matrix and returns the resulting matrix.

scaleNonUniform(in float scaleFactorX, in float scaleFactorY) 
SVGMatrix 
Postmultiplies a nonuniform scale transformation on the current matrix and returns the resulting matrix.

rotate(in float angle) 
SVGMatrix 
Postmultiplies a rotation transformation on the current matrix and returns the resulting matrix.

rotateFromVector(in float x, in float y) 
SVGMatrix 
Postmultiplies a rotation transformation on the current matrix and returns the resulting matrix. The rotation angle is determined by taking (+/) atan(y/x). The direction of the vector (x, y) determines whether the positive or negative angle value is used. Exceptions:

flipX() 
SVGMatrix 
Postmultiplies the transformation [1 0 0 1 0 0] and returns the resulting matrix.

flipY() 
SVGMatrix 
Postmultiplies the transformation [1 0 0 1 0 0] and returns the resulting matrix.

skewX(in float angle) 
SVGMatrix 
Postmultiplies a skewX transformation on the current matrix and returns the resulting matrix.

skewY(in float angle) 
SVGMatrix 
Postmultiplies a skewY transformation on the current matrix and returns the resulting matrix.
