SVGTransform

The SVGTransform interface reflects one of the component transformations within an SVGTransformList; thus, an SVGTransform object corresponds to a single component (e.g., scale(...) or matrix(...)) within a transform attribute.

An SVGTransform object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.

Instance properties

type

The type of the value as specified by one of the SVG_TRANSFORM_* constants defined on this interface.

angle

The angle as a floating point value. A convenience attribute for SVG_TRANSFORM_ROTATE, SVG_TRANSFORM_SKEWX and SVG_TRANSFORM_SKEWY. For SVG_TRANSFORM_MATRIX, SVG_TRANSFORM_TRANSLATE and SVG_TRANSFORM_SCALE, angle will be zero.

matrix

The matrix as a DOMMatrix that represents this transformation. The matrix object is live, meaning that any changes made to the SVGTransform object are immediately reflected in the matrix object and vice versa. In case the matrix object is changed directly (i.e., without using the methods on the SVGTransform interface itself) then the type of the SVGTransform changes to SVG_TRANSFORM_MATRIX.

Instance methods

setMatrix()

Sets the transform type to SVG_TRANSFORM_MATRIX, with parameter matrix defining the new transformation. Note that the values from the parameter matrix are copied.

setTranslate()

Sets the transform type to SVG_TRANSFORM_TRANSLATE, with parameters tx and ty defining the translation amounts.

setScale()

Sets the transform type to SVG_TRANSFORM_SCALE, with parameters sx and sy defining the scale amounts.

setRotate()

Sets the transform type to SVG_TRANSFORM_ROTATE, with parameter angle defining the rotation angle and parameters cx and cy defining the optional center of rotation.

setSkewX()

Sets the transform type to SVG_TRANSFORM_SKEWX, with parameter angle defining the amount of skew.

setSkewY()

Sets the transform type to SVG_TRANSFORM_SKEWY, with parameter angle defining the amount of skew.

Static properties

SVG_TRANSFORM_UNKNOWN (0)

The unit type is not one of predefined unit types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.

SVG_TRANSFORM_MATRIX (1)

A matrix(...) transformation.

SVG_TRANSFORM_TRANSLATE (2)

A translate(...) transformation.

SVG_TRANSFORM_SCALE (3)

A scale(...) transformation.

SVG_TRANSFORM_ROTATE (4)

A rotate(...) transformation.

SVG_TRANSFORM_SKEWX (5)

A skewx(...) transformation.

SVG_TRANSFORM_SKEWY (6)

A skewy(...) transformation.
