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.
警告： SVG 2 replaced the SVGMatrix interface by the more general DOMMatrix and DOMMatrixReadOnly (en-US) interfaces.
Properties
SVGMatrix.a-
A float representing the a component of the matrix.
SVGMatrix.b-
A float representing the b component of the matrix.
SVGMatrix.c-
A float representing the c component of the matrix.
SVGMatrix.d-
A float representing the d component of the matrix.
SVGMatrix.e-
A float representing the e component of the matrix.
SVGMatrix.f-
A float representing the f component of the matrix.
Methods
SVGMatrix.multiply()-
Performs matrix multiplication. This matrix is post-multiplied by another matrix, returning the resulting new matrix as
SVGMatrix. SVGMatrix.inverse()-
Returns the inverse matrix as
SVGMatrix. SVGMatrix.translate()-
Post-multiplies a translation transformation on the current matrix and returns the resulting matrix as
SVGMatrix. SVGMatrix.scale()-
Post-multiplies a uniform scale transformation on the current matrix and returns the resulting matrix as
SVGMatrix. SVGMatrix.scaleNonUniform()-
Post-multiplies a non-uniform scale transformation on the current matrix and returns the resulting matrix as
SVGMatrix. SVGMatrix.rotate()-
Post-multiplies a rotation transformation on the current matrix and returns the resulting matrix as
SVGMatrix. SVGMatrix.rotateFromVector()-
Post-multiplies a rotation transformation on the current matrix and returns the resulting matrix as
SVGMatrix. 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. SVGMatrix.flipX()-
Post-multiplies the transformation [-1 0 0 1 0 0] and returns the resulting matrix as
SVGMatrix. SVGMatrix.flipY()-
Post-multiplies the transformation [1 0 0 -1 0 0] and returns the resulting matrix as
SVGMatrix. SVGMatrix.skewX()-
Post-multiplies a skewX transformation on the current matrix and returns the resulting matrix as
SVGMatrix. SVGMatrix.skewY()-
Post-multiplies a skewY transformation on the current matrix and returns the resulting matrix as
SVGMatrix.
Exceptions
A DOMException with the code NO_MODIFICATION_ALLOWED_ERR is raised when attempting updating a read-only attribute or when the object itself is read-only.
