SVGLocatable

Extended by SVGSVGElement, SVGTransformable, SVGTransformable, SVGSVGElement

Properties
SVGElement	farthestViewportElement The farthest ancestor ‘svg’ element. Null if the current element is the outermost svg element.
SVGElement	nearestViewportElement The element which established the current viewport. Often, the nearest ancestor ‘svg’ element. Null if the current element is the outermost svg element.

Operations
SVGRect	getBBox() Returns the tight bounding box in current user space (i.e., after application of the ‘transform’ attribute, if any) on the geometry of all contained graphics elements, exclusive of stroking, clipping, masking and filter effects). Note that getBBox must return the actual bounding box at the time the method was called, even in case the element has not yet been rendered.
SVGMatrix	getCTM() Returns the transformation matrix from current user units (i.e., after application of the ‘transform’ attribute, if any) to the viewport coordinate system for the nearestViewportElement. Returns An SVGMatrix object that defines the CTM.
SVGMatrix	getScreenCTM() Returns the transformation matrix from current user units (i.e., after application of the ‘transform’ attribute, if any) to the parent user agent's notice of a "pixel". For display devices, ideally this represents a physical screen pixel. For other devices or environments where physical pixel sizes are not known, then an algorithm similar to the CSS2 definition of a "pixel" can be used instead.
SVGMatrix	getTransformToElement(SVGElement element) Returns the transformation matrix from the user coordinate system on the current element (after application of the ‘transform’ attribute, if any) to the user coordinate system on parameter element (after application of its ‘transform’ attribute, if any).
