The ElementTimeControl interface, part of the org.w3c.dom.smil module and defined in SMIL Animation: Supported interfaces, defines common methods for elements which define animation behaviors compatible with SMIL Animation.

Calling beginElement causes the animation to begin in the same way that an animation with event-based begin timing begins. The effective begin time is the current presentation time at the time of the DOM method call. Note that beginElement is subject to the 'set/restart' attribute in the same manner that event-based begin timing is. If an animation is specified to disallow restarting at a given point, beginElement methods calls must fail. Refer also to the section Restarting animation.

Calling beginElementAt has the same behavior as beginElement, except that the effective begin time is offset from the current presentation time by an amount specified as a parameter. Passing a negative value for the offset causes the element to begin as for beginElement, but has the effect that the element begins at the specified offset into its active duration. The beginElementAt method must also respect the 'set/restart' attribute. The restart semantics for a beginElementAt method call are evaluated at the time of the method call, and not at the effective begin time specified by the offset parameter.

Calling endElement causes an animation to end the active duration, just as 'animate/end' does. Depending upon the value of the 'animate/fill' attribute, the animation effect may no longer be applied, or it may be frozen at the current effect. Refer also to the section Freezing animations. If an animation is not currently active (i.e. if it has not yet begun or if it is frozen), the endElement method will fail.

Calling endElementAt causes an animation to end the active duration, just as endElement does, but allows the caller to specify a positive offset, to cause the element to end at a point in the future. Other than delaying when the end actually happens, the semantics are identical to those for endElement. If endElementAt is called more than once while an element is active, the end time specified by the last method call will determine the end behavior.

The TimeEvent interface, defined in SMIL Animation: Supported interfaces, provides specific contextual information associated with Time events.

The different types of events that can occur are:

beginEvent
This event is raised when the element local timeline begins to play. It will be raised each time the element begins the active duration (i.e. when it restarts, but not when it repeats). It may be raised both in the course of normal (i.e. scheduled or interactive) timeline play, as well as in the case that the element was begun with the ElementTimeControl::beginElement or ElementTimeControl::beginElementAt methods. Note that if an element is restarted while it is currently playing, the element will raise an end event and another begin event, as the element restarts.
  • Bubbles: No
  • Cancelable: No
  • Context Info: None
endEvent
This event is raised at the active end of the element. Note that this event is not raised at the simple end of each repeat. This event may be raised both in the course of normal (i.e. scheduled or interactive) timeline play, as well as in the case that the element was ended with the ElementTimeControl::endElement or ElementTimeControl::endElementAt methods. Note that if an element is restarted while it is currently playing, the element will raise an end event and another begin event, as the element restarts.
  • Bubbles: No
  • Cancelable: No
  • Context Info: None
repeatEvent
This event is raised when an element local timeline repeats. It will be raised each time the element repeats, after the first iteration.
The event provides a numerical indication of which repeat iteration is beginning. The value is a 0-based integer, but the repeat event is not raised for the first iteration and so the observed values of the detail attribute will be >= 1.
  • Bubbles: No
  • Cancelable: No
  • Context Info: detail (current iteration)
 The view attribute identifies the AbstractView [DOM2VIEWS] from which the event was generated. Specifies some detail information about the Event, depending on the type of the event. For this event type, indicates the repeat number for the animation. The initTimeEvent method is used to initialize the value of a TimeEvent created through the DocumentEvent interface. This method may only be called before the TimeEvent has been dispatched via the dispatchEvent method, though it may be called multiple times during that phase if necessary. If called multiple times, the final invocation takes precedence. Specifies the event type. Specifies the Event's AbstractView. Specifies the Event's detail. This exception is raised when a specific SVG operation is impossible to perform. A code identifying the reason why the requested operation could not be performed. The value of this member will be one of the constants in the SVGException code group. Raised when an object of the wrong type is passed to an operation. Raised when an invalid value is passed to an operation or assigned to an attribute.

Raised when an attempt is made to invert a matrix that is not invertible.

Note the unusual spelling of this constant, which is necessary for compatibility with existing content.

 All of the SVG DOM interfaces that correspond directly to elements in the SVG language (such as the SVGPathElement interface for the 'path' element) derive from the SVGElement interface.

If the given attribute or property is not currently being animated, then this attribute contains the same value as baseVal. The SVGLength interface corresponds to the <length> basic data type. 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. No unit type was provided (i.e., a unitless value was specified), which indicates a value in user units. A percentage value was specified. A value was specified using the em units defined in CSS 2.

Object attributes unitType, valueInSpecifiedUnits and valueAsString might be modified as a result of this method. For example, if the original value were "0.5cm" and the method was invoked to convert to millimeters, then the unitType would be changed to SVG_LENGTHTYPE_MM, valueInSpecifiedUnits would be changed to the numeric value 5 and valueAsString would be changed to "5mm". The unit type to switch to (e.g., SVG_LENGTHTYPE_MM). Used for attributes of basic type <length> which can be animated. The base value of the given attribute before applying any animations. If the given attribute or property is being animated, contains the current animated value of the attribute or property, and both the object itself and its contents are readonly.

If the given attribute or property is not currently being animated, contains the same value as baseVal. The SVGAngle interface corresponds to the <angle> basic data type. 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. No unit type was provided (i.e., a unitless value was specified). For angles, a unitless value is treated the same as if degrees were specified. The unit type was explicitly set to degrees. The unit type is radians. The unit type is radians. The type of the value as specified by one of the SVG_ANGLETYPE_* constants defined on this interface. The angle value as a floating point value, in degrees. Setting this attribute will cause valueInSpecifiedUnits and valueAsString to be updated automatically to reflect this setting. Raised when the list cannot be modified. The angle value as a floating point value, in the units expressed by unitType. Setting this attribute will cause value and valueAsString to be updated automatically to reflect this setting. Raised when the list cannot be modified.

If the given attribute or property is not currently being animated, contains the same value as baseVal.

The SVGColor interface corresponds to color value definition for properties 'stop-color', 'flood-color' and 'lighting-color' and is a base class for interface SVGPaint. It incorporates SVG's extended notion of color, which incorporates ICC-based color specifications.

Interface SVGColor does not correspond to the <color> basic data type. For the <color> basic data type, the applicable DOM interfaces are defined in DOM Level 2 Style; in particular, see the RGBColor interface ([DOM2STYLE], section 2.2).

 The color type is not one of predefined 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. An sRGB color has been specified without an alternative ICC color specification. An sRGB color has been specified along with an alternative ICC color specification. Corresponds to when keyword currentColor has been specified. The type of the value as specified by one of the SVG_COLORTYPE_* constants defined on this interface. The color specified in the sRGB color space. The alternate ICC color specification. Modifies the color value to be the specified sRGB color without an alternate ICC color specification. Raised if rgbColor does not match <color>. A string that matches <color>, which specifies the new sRGB color value. Modifies the color value to be the specified sRGB color with an alternate ICC color specification. Raised if rgbColor does not match <color> or if iccColor does not match XXX need icc-color grammar symbol A string that matches <color>, which specifies the new sRGB color value. A string that matches XXX need icc-color grammar symbol, which specifies the alternate ICC color specification. Sets the color value as specified by the parameters. If colorType requires an RGBColor, then rgbColor must be a string that matches <color>; otherwise, rgbColor. must be null. If colorType requires an SVGICCColor, then iccColor must be a string that matches XXX need icc-color grammar symbol; otherwise, iccColor must be null. Raised if one of the parameters has an invalid value. One of the defined constants for colorType. The specification of an sRGB color, or null. The specification of an ICC color, or null. The SVGICCColor interface expresses an ICC-based color specification. The name of the color profile, which is the first parameter of an ICC color specification. Raised on an attempt to change the value of a readonly attribute. The list of color values that define this ICC color. Each color value is an arbitrary floating point number. Rectangles are defined as consisting of a (x,y) coordinate pair identifying a minimum X value, a minimum Y value, and a width and height, which are usually constrained to be non-negative. Corresponds to attribute x on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute y on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute width on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute height on the given element. Raised on an attempt to change the value of a readonly attribute. Used for attributes of type SVGRect which can be animated. The base value of the given attribute before applying any animations. If the given attribute or property is being animated, contains the current animated value of the attribute or property, and both the object itself and its contents are readonly. If the given attribute or property is not currently being animated, contains the same value as baseVal. The SVGUnitTypes interface defines a commonly used set of constants and is a base interface used by SVGGradientElement, SVGPatternElement, SVGClipPathElement, SVGMaskElement and SVGFilterElement. The type is not one of predefined 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. Corresponds to value 'userSpaceOnUse'. Corresponds to value 'objectBoundingBox'. The SVGStylable interface is implemented on all objects corresponding to SVG elements that can have 'style attribute', 'class' and presentation attributes specified on them. It is thus an ancestor interface for many of the interfaces defined in this specification. Corresponds to attribute 'class' on the given element. Corresponds to attribute 'style attribute' on the given element. If the user agent does not support styling with CSS, then this attribute must always have the value of null. Returns the base (i.e., static) value of a given presentation attribute as an object of type CSSValue. The returned object is live; changes to the objects represent immediate changes to the objects to which the CSSValue is attached. The static/base value of the given presentation attribute as a CSSValue, or null if the given attribute does not have a specified value. The name of the presentation attribute whose value is to be returned. Interface SVGLocatable is for all elements which either have a 'transform' attribute or don't have a 'transform' attribute but whose content can have a bounding box in current user space. The element which established the current viewport. Often, the nearest ancestor 'svg' element. Null if the current element is the outermost 'svg' element. The farthest ancestor 'svg' element. Null if the current element is the outermost 'svg' element. 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 and filter effects). An SVGRect object that defines the bounding box. 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. An SVGMatrix object that defines the CTM. 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 CSS 2 definition of a "pixel" can be used instead. An SVGMatrix object that defines the given transformation matrix. 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). An SVGMatrix object that defines the transformation. Raised if the currently defined transformation matrices make it impossible to compute the given matrix (e.g., because one of the transformations is singular). The target element. Interface SVGTransformable contains properties and methods that apply to all elements which have attribute 'transform'. Corresponds to attribute 'transform' on the given element. Interface SVGTests defines an interface which applies to all elements which have attributes 'requiredFeatures', 'requiredExtensions' and 'systemLanguage'. Corresponds to attribute 'requiredFeatures' on the given element. Corresponds to attribute 'requiredExtensions' on the given element. Corresponds to attribute 'systemLanguage' on the given element. Returns true if the user agent supports the given extension, specified by a URI. True or false, depending on whether the given extension is supported. The name of the extension, expressed as a URI. Interface SVGLangSpace defines an interface which applies to all elements which have attributes 'xml:lang' and 'xml:space'. Corresponds to attribute 'xml:lang' on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute 'xml:space' on the given element. Raised on an attempt to change the value of a readonly attribute. Interface SVGExternalResourcesRequired defines an interface which applies to all elements where this element or one of its descendants can reference an external resource. Corresponds to attribute 'externalResourcesRequired' on the given element. Note that the SVG DOM defines the attribute 'externalResourcesRequired' as being of type SVGAnimatedBoolean, whereas the SVG language definition says that 'externalResourcesRequired' is not animated. Because the SVG language definition states that 'externalResourcesRequired' cannot be animated, the SVGAnimatedBoolean::animVal will always be the same as the SVGAnimatedBoolean::baseVal. Interface SVGFitToViewBox defines DOM attributes that apply to elements which have XML attributes 'viewBox' and 'preserveAspectRatio'. Corresponds to attribute 'viewBox' on the given element. Corresponds to attribute 'preserveAspectRatio' on the given element. The SVGZoomAndPan interface defines attribute zoomAndPan and associated constants. The enumeration was set to a value that is not one of predefined 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. Corresponds to value 'disable'. Corresponds to value 'magnify'. Corresponds to attribute 'zoomAndPan' on the given element. The value must be one of the SVG_ZOOMANDPAN_* constants defined on this interface. Raised on an attempt to change the value of a readonly attribute. The interface corresponds to an SVG View Specification. Corresponds to the transform setting on the SVG View Specification. Corresponds to the viewTarget setting on the SVG View Specification. Corresponds to the viewBox setting on the SVG View Specification. Corresponds to the preserveAspectRatio setting on the SVG View Specification. Corresponds to the transform setting on the SVG View Specification. Corresponds to the viewTarget setting on the SVG View Specification. Interface SVGURIReference defines an interface which applies to all elements which have the collection of XLink attributes, such as 'xlink:href', which define a URI reference. Corresponds to attribute 'xlink:href' on the given element.

SVG extends interface CSSRule with interface SVGCSSRule by adding an SVGColorProfileRule rule to allow for specification of ICC-based color.

It is likely that this extension will become part of a future version of CSS and DOM.

 The rule is an @color-profile. The SVGRenderingIntent interface defines the enumerated list of possible values for 'color-profile/rendering-intent' attributes or descriptors. The type is not one of predefined 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. Corresponds to a value of 'auto'. Corresponds to a value of 'perceptual'. Corresponds to a value of 'relative-colorimetric'. Corresponds to a value of 'saturation'. Corresponds to a value of 'absolute-colorimetric'.

When an 'svg' element is embedded inline as a component of a document from another namespace, such as when an 'svg' element is embedded inline within an XHTML document [XHTML], then an SVGDocument object will not exist; instead, the root object in the document object hierarchy will be a Document object of a different type, such as an HTMLDocument object.

However, an SVGDocument object will indeed exist when the root element of the XML document hierarchy is an 'svg' element, such as when viewing a stand-alone SVG file (i.e., a file with MIME type "image/svg+xml"). In this case, the SVGDocument object will be the root object of the document object model hierarchy.

In the case where an SVG document is embedded by reference, such as when an XHTML document has an 'object' element whose 'href' attribute references an SVG document (i.e., a document whose MIME type is "image/svg+xml" and whose root element is thus an 'svg' element), there will exist two distinct DOM hierarchies. The first DOM hierarchy will be for the referencing document (e.g., an XHTML document). The second DOM hierarchy will be for the referenced SVG document. In this second DOM hierarchy, the root object of the document object model hierarchy is an SVGDocument object.

The SVGDocument interface contains a similar list of attributes and methods to the HTMLDocument interface described in the Document Object Model (HTML) Level 1 chapter of the [DOM1] specification.

 The title of a document as specified by the 'title' sub-element of the 'svg' root element (i.e., <svg><title>Here is the title</title>...</svg>) Returns the URI of the page that linked to this page. The value is an empty string if the user navigated to the page directly (not through a link, but, for example, via a bookmark). The domain name of the server that served the document, or a null string if the server cannot be identified by a domain name. The complete URI of the document. The root 'svg' in the document hierarchy.

A key interface definition is the SVGSVGElement interface, which is the interface that corresponds to the 'svg' element. This interface contains various miscellaneous commonly-used utility methods, such as matrix operations and the ability to control the time of redraw on visual rendering devices.

SVGSVGElement extends ViewCSS and DocumentCSS to provide access to the computed values of properties and the override style sheet as described in DOM Level 2 Style [DOM2STYLE].

 Corresponds to attribute 'x' on the given 'svg' element. Corresponds to attribute 'y' on the given 'svg' element. Corresponds to attribute 'width' on the given 'svg' element. Corresponds to attribute 'height' on the given 'svg' element. Corresponds to attribute 'contentScriptType' on the given 'svg' element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute 'contentStyleType' on the given 'svg' element. Raised on an attempt to change the value of a readonly attribute.

The position and size of the viewport (implicit or explicit) that corresponds to this 'svg' element. When the user agent is actually rendering the content, then the position and size values represent the actual values when rendering. The position and size values are unitless values in the coordinate system of the parent element. If no parent element exists (i.e., 'svg' element represents the root of the document tree), if this SVG document is embedded as part of another document (e.g., via the HTML 'object' element), then the position and size are unitless values in the coordinate system of the parent document. (If the parent uses CSS or XSL layout, then unitless values represent pixel units for the current CSS or XSL viewport, as described in the CSS 2 specification.) If the parent element does not have a coordinate system, then the user agent should provide reasonable default values for this attribute.

The object itself and its contents are both readonly.

 Size of a pixel units (as defined by CSS 2) along the x-axis of the viewport, which represents a unit somewhere in the range of 70dpi to 120dpi, and, on systems that support this, might actually match the characteristics of the target medium. On systems where it is impossible to know the size of a pixel, a suitable default pixel size is provided. Corresponding size of a pixel unit along the y-axis of the viewport. User interface (UI) events in DOM Level 2 indicate the screen positions at which the given UI event occurred. When the user agent actually knows the physical size of a "screen unit", this attribute will express that information; otherwise, user agents will provide a suitable default value such as .28mm. Corresponding size of a screen pixel along the y-axis of the viewport. The initial view (i.e., before magnification and panning) of the current innermost SVG document fragment can be either the "standard" view (i.e., based on attributes on the 'svg' element such as 'viewBox') or to a "custom" view (i.e., a hyperlink into a particular 'view' or other element - see Linking into SVG content: URI fragments and SVG views). If the initial view is the "standard" view, then this attribute is false. If the initial view is a "custom" view, then this attribute is true. Raised on an attempt to change the value of a readonly attribute.

The definition of the initial view (i.e., before magnification and panning) of the current innermost SVG document fragment. The meaning depends on the situation:

The object itself and its contents are both readonly.

 This attribute indicates the current scale factor relative to the initial view to take into account user magnification and panning operations, as described under Magnification and panning. DOM attributes currentScale and currentTranslate are equivalent to the 2x3 matrix [a b c d e f] = [currentScale 0 0 currentScale currentTranslate.x currentTranslate.y]. If "magnification" is enabled (i.e., zoomAndPan="magnify"), then the effect is as if an extra transformation were placed at the outermost level on the SVG document fragment (i.e., outside the outermost 'svg' element). Raised on an attempt to change the value of a readonly attribute. The corresponding translation factor that takes into account user "magnification". Takes a time-out value which indicates that redraw shall not occur until: (a) the corresponding unsuspendRedraw(suspend_handle_id) call has been made, (b) an unsuspendRedrawAll() call has been made, or (c) its timer has timed out. In environments that do not support interactivity (e.g., print media), then redraw shall not be suspended. suspend_handle_id = suspendRedraw(max_wait_milliseconds) and unsuspendRedraw(suspend_handle_id) must be packaged as balanced pairs. When you want to suspend redraw actions as a collection of SVG DOM changes occur, then precede the changes to the SVG DOM with a method call similar to suspend_handle_id = suspendRedraw(max_wait_milliseconds) and follow the changes with a method call similar to unsuspendRedraw(suspend_handle_id). Note that multiple suspendRedraw calls can be used at once and that each such method call is treated independently of the other suspendRedraw method calls. A number which acts as a unique identifier for the given suspendRedraw() call. This value must be passed as the parameter to the corresponding unsuspendRedraw() method call. The amount of time in milliseconds to hold off before redrawing the device. Values greater than 60 seconds will be truncated down to 60 seconds. Cancels a specified suspendRedraw() by providing a unique suspend_handle_id. This method will raise a DOMException with value NOT_FOUND_ERR if an invalid value (i.e., no such suspend_handle_id is active) for suspend_handle_id is provided. A number which acts as a unique identifier for the desired suspendRedraw() call. The number supplied must be a value returned from a previous call to suspendRedraw() Cancels all currently active suspendRedraw() method calls. This method is most useful at the very end of a set of SVG DOM calls to ensure that all pending suspendRedraw() method calls have been cancelled. In rendering environments supporting interactivity, forces the user agent to immediately redraw all regions of the viewport that require updating. Suspends (i.e., pauses) all currently running animations that are defined within the SVG document fragment corresponding to this 'svg' element, causing the animation clock corresponding to this document fragment to stand still until it is unpaused. Unsuspends (i.e., unpauses) currently running animations that are defined within the SVG document fragment, causing the animation clock to continue from the time at which it was suspended.

The SVGSVGElement interface corresponds to the 'g' element. The SVGDefsElement interface corresponds to the 'defs' element. The SVGDescElement interface corresponds to the 'desc' element. The SVGTitleElement interface corresponds to the 'title' element. The SVGSymbolElement interface corresponds to the 'symbol' element. The SVGUseElement interface corresponds to the 'use' element. Corresponds to attribute 'x' on the given 'use' element. Corresponds to attribute 'y' on the given 'use' element. Corresponds to attribute 'width' on the given 'use' element. Corresponds to attribute 'height' on the given 'use' element. The root of the "instance tree". See description of SVGElementInstance for a discussion on the instance tree. If the 'xlink:href' attribute is being animated, contains the current animated root of the "instance tree". If the 'xlink:href' attribute is not currently being animated, contains the same value as instanceRoot. See description of SVGElementInstance for a discussion on the instance tree.

For each 'use' element, the SVG DOM maintains a shadow tree (the "instance tree") of objects of type SVGElementInstance. An SVGElementInstance represents a single node in the instance tree. The root object in the instance tree is pointed to by the SVGUseElement::instanceRoot attribute on the SVGUseElement object for the corresponding 'use' element.

If the 'use' element references a simple graphics element such as a 'rect', then there is only a single SVGElementInstance object, and the correspondingElement attribute on this SVGElementInstance object is the SVGRectElement that corresponds to the referenced 'rect' element.

If the 'use' element references a 'g' which contains two 'rect' elements, then the instance tree contains three SVGElementInstance objects, a root SVGElementInstance object whose correspondingElement is the SVGGElement object for the 'g', and then two child SVGElementInstance objects, each of which has its correspondingElement that is an SVGRectElement object.

If the referenced object is itself a 'use', or if there are 'use' subelements within the referenced object, the instance tree will contain recursive expansion of the indirect references to form a complete tree. For example, if a 'use' element references a 'g', and the 'g' itself contains a 'use', and that 'use' references a 'rect', then the instance tree for the original (outermost) 'use' will consist of a hierarchy of SVGElementInstance objects, as follows:

SVGElementInstance #1 (parentNode=null, firstChild=#2, correspondingElement is the 'g')
  SVGElementInstance #2 (parentNode=#1, firstChild=#3, correspondingElement is the other 'use')
    SVGElementInstance #3 (parentNode=#2, firstChild=null, correspondingElement is the 'rect')
The corresponding element to which this object is an instance. For example, if a 'use' element references a 'rect' element, then an SVGElementInstance is created, with its correspondingElement being the SVGElementInstance object for the 'rect' element. The corresponding 'use' element to which this SVGElementInstance object belongs. When 'use' elements are nested (e.g., a 'use' references another 'use' which references a graphics element such as a 'rect'), then the correspondingUseElement is the outermost 'use' (i.e., the one which indirectly references the 'rect', not the one with the direct reference). The parent of this SVGElementInstance within the instance tree. All SVGElementInstance objects have a parent except the SVGElementInstance which corresponds to the element which was directly referenced by the 'use' element, in which case parentNode is null. An SVGElementInstanceList that contains all children of this SVGElementInstance within the instance tree. If there are no children, this is an SVGElementInstanceList containing no entries (i.e., an empty list). The first child of this SVGElementInstance within the instance tree. If there is no such SVGElementInstance, this returns null. The last child of this SVGElementInstance within the instance tree. If there is no such SVGElementInstance, this returns null. The SVGElementInstance immediately preceding this SVGElementInstance. If there is no such SVGElementInstance, this returns null. The SVGElementInstance immediately following this SVGElementInstance. If there is no such SVGElementInstance, this returns null. The SVGElementInstanceList interface provides the abstraction of an ordered collection of SVGElementInstance objects, without defining or constraining how this collection is implemented. The number of SVGElementInstance objects in the list. The range of valid child indices is 0 to length−1 inclusive. Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null. The SVGElementInstance object at the indexth position in the SVGElementInstanceList, or null if that is not a valid index. Index into the collection. The SVGImageElement interface corresponds to the 'image' element. Corresponds to attribute 'x' on the given 'image' element. Corresponds to attribute 'y' on the given 'image' element. Corresponds to attribute 'width' on the given 'image' element. Corresponds to attribute 'height' on the given 'image' element. Corresponds to attribute 'preserveAspectRatio' on the given 'image' element. The SVGSwitchElement interface corresponds to the 'switch' element. In the case where an SVG document is embedded by reference, such as when an XHTML document has an 'object' element whose 'href' (or equivalent) attribute references an SVG document (i.e., a document whose MIME type is "image/svg+xml" and whose root element is thus an 'svg' element), the SVG user agent is required to implement the GetSVGDocument interface for the element which references the SVG document (e.g., the HTML 'object' or comparable referencing elements). Returns the SVGDocument object for the referenced SVG document. The SVGDocument object for the referenced SVG document. No SVGDocument object is available. The SVGStyleElement interface corresponds to the 'style element' element. Corresponds to attribute 'xml:space' on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute 'type' on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute 'media' on the given element. Raised on an attempt to change the value of a readonly attribute. Corresponds to attribute 'title attribute' on the given element. Raised on an attempt to change the value of a readonly attribute.

The SVGAnimatedPathData interface supports elements which have a 'd' attribute which holds SVG path data, and supports the ability to animate that attribute.

The SVGAnimatedPathData interface provides two lists to access and modify the base (i.e., static) contents of the 'd' attribute:

  • DOM attribute pathSegList provides access to the static/base contents of the 'd' attribute in a form which matches one-for-one with SVG's syntax.
  • DOM attribute normalizedPathSegList provides normalized access to the static/base contents of the 'd' attribute where all path data commands are expressed in terms of the following subset of SVGPathSeg types: SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z).

and two lists to access the current animated values of the 'd' attribute:

  • DOM attribute animatedPathSegList provides access to the current animated contents of the 'd' attribute in a form which matches one-for-one with SVG's syntax.
  • DOM attribute animatedNormalizedPathSegList provides normalized access to the current animated contents of the 'd' attribute where all path data commands are expressed in terms of the following subset of SVGPathSeg types: SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z).

Each of the two lists are always kept synchronized. Modifications to one list will immediately cause the corresponding list to be modified. Modifications to normalizedPathSegList might cause entries in pathSegList to be broken into a set of normalized path segments.

Additionally, the 'path/d' attribute on the 'path' element accessed via the XML DOM (e.g., using the getAttribute() method call) will reflect any changes made to pathSegList or normalizedPathSegList.

 Provides access to the base (i.e., static) contents of the 'd' attribute in a form which matches one-for-one with SVG's syntax. Thus, if the 'd' attribute has an "absolute moveto (M)" and an "absolute arcto (A)" command, then pathSegList will have two entries: a SVG_PATHSEG_MOVETO_ABS and a SVG_PATHSEG_ARC_ABS.

Provides access to the base (i.e., static) contents of the 'd' attribute in a form where all path data commands are expressed in terms of the following subset of SVGPathSeg types: SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z). Thus, if the 'd' attribute has an "absolute moveto (M)" and an "absolute arcto (A)" command, then pathSegList will have one SVG_PATHSEG_MOVETO_ABS entry followed by a series of SVG_PATHSEG_LINETO_ABS entries which approximate the arc. This alternate representation is available to provide a simpler interface to developers who would benefit from a more limited set of commands.

The only valid SVGPathSeg types are SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z).

 Provides access to the current animated contents of the 'd' attribute in a form which matches one-for-one with SVG's syntax. If the given attribute or property is being animated, contains the current animated value of the attribute or property, and both the object itself and its contents are readonly. If the given attribute or property is not currently being animated, contains the same value as pathSegList. Provides access to the current animated contents of the 'd' attribute in a form where all path data commands are expressed in terms of the following subset of SVGPathSeg types: SVG_PATHSEG_MOVETO_ABS (M), SVG_PATHSEG_LINETO_ABS (L), SVG_PATHSEG_CURVETO_CUBIC_ABS (C) and SVG_PATHSEG_CLOSEPATH (z).

The SVG event set contains a list of special event types which are available in SVG.

A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the SVG event set has been implemented by a DOM implementation. The feature string for this event set is "SVGEvents". This string is also used with the createEvent method.

The SVG events use the base DOM Event interface to pass contextual information.

The different types of such events that can occur are:

SVGLoad
See SVGLoad event.
  • Bubbles: No
  • Cancelable: No
  • Context Info: None
SVGUnload
See SVGUnload event.
  • Bubbles: No
  • Cancelable: No
  • Context Info: None
SVGAbort
See SVGAbort event.
  • Bubbles: Yes
  • Cancelable: No
  • Context Info: None
SVGError
See SVGError event.
  • Bubbles: Yes
  • Cancelable: No
  • Context Info: None
SVGResize
See SVGResize event.
  • Bubbles: Yes
  • Cancelable: No
  • Context Info: None
SVGScroll
See SVGScroll event.
  • Bubbles: Yes
  • Cancelable: No
  • Context Info: None

A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the SVG zoom event set has been implemented by a DOM implementation. The feature string for this event set is "SVGZoomEvents". This string is also used with the createEvent method.

The zoom event handler occurs before the zoom event is processed. The remainder of the DOM represents the previous state of the document. The document will be updated upon normal return from the event handler.

The UI event type for a zoom event is:

SVGZoom
The zoom event occurs when the user initiates an action which causes the current view of the SVG document fragment to be rescaled. Event handlers are only recognized on 'svg' elements. See SVGZoom event.
  • Bubbles: Yes
  • Cancelable: No
  • Context Info: zoomRectScreen, previousScale, previousTranslate, newScale, newTranslate, screenX, screenY, clientX, clientY, altKey, ctrlKey, shiftKey, metaKey, relatedNode.
    (screenX, screenY, clientX and clientY indicate the center of the zoom area, with clientX and clientY in viewport coordinates for the corresponding 'svg' element. relatedNode is the corresponding 'svg' element.)

The specified zoom rectangle in screen units.

The object itself and its contents are both readonly.

 The scale factor from previous zoom operations that was in place before the zoom operation occurred.

The translation values from previous zoom operations that were in place before the zoom operation occurred.

The object itself and its contents are both readonly.

 The scale factor that will be in place after the zoom operation has been processed.

The translation values that will be in place after the zoom operation has been processed.

The object itself and its contents are both readonly.

The SVGAnimationElement interface is the base interface for all of the animation element interfaces: SVGAnimateElement, SVGSetElement, SVGAnimateColorElement, SVGAnimateMotionElement and SVGAnimateTransformElement.

Unlike other SVG DOM interfaces, the SVG DOM does not specify convenience DOM properties corresponding to the various language attributes on SVG's animation elements. Specification of these convenience properties in a way that will be compatible with future versions of SMIL Animation is expected in a future version of SVG. The current method for accessing and modifying the attributes on the animation elements is to use the standard getAttribute, setAttribute, getAttributeNS and setAttributeNS defined in DOM Level 2 Core [DOM2].

 The element which is being animated. Returns the start time in seconds for this animation. The start time in seconds for this animation relative to the start time of the time container. Returns the current time in seconds relative to time zero for the given time container. The current time in seconds relative to time zero for the given time container. Returns the number of seconds for the simple duration for this animation. If the simple duration is undefined (e.g., the end time is indefinite), then an exception is raised. number of seconds for the simple duration for this animation. The simple duration is not determined on the given element.
