SVGTransform
SVG transform interface
SVGTransform
is the interface for 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.

type |
unsigned short | The type of the value as specified by one of the SVG_TRANSFORM_* constants defined on this interface. |
angle |
float |
A convenience attribute for SVG_TRANSFORM_ROTATE ,
SVG_TRANSFORM_SKEWX and SVG_TRANSFORM_SKEWY .
It holds the angle that was specified.For SVG_TRANSFORM_MATRIX ,
SVG_TRANSFORM_TRANSLATE and
SVG_TRANSFORM_SCALE , angle will be zero.
