SVGGeometryElement class

Interface SVGGeometryElement represents SVG elements whose rendering is defined by geometry with an equivalent path, and which can be filled and stroked. This includes paths and the basic shapes.

Inheritance: SVGGeometryElement → SVGGraphicsElement → SVGElement → Element → Node → EventTarget → DOMObject

The SVGGeometryElement type exposes the following members:

Properties

Property	Description
node_type	A code representing the type of the underlying object.
local_name	Returns the local part of the qualified name of this node. For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.
namespace_uri	The namespace URI of this node, or null if it is unspecified.
prefix	The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect
node_name	The name of this node, depending on its type.
base_uri	The absolute base URI of this node or null if the implementation wasn’t able to obtain an absolute URI.
owner_document	The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.
parent_node	The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
parent_element	Gets the parent `Element` of this node.
child_nodes	A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes..
first_child	The first child of this node. If there is no such node, this returns null.
last_child	The last child of this node. If there is no such node, this returns null.
previous_sibling	The node immediately preceding this node. If there is no such node, this returns null.
next_sibling	The node immediately following this node. If there is no such node, this returns null.
node_value	The value of this node, depending on its type.
text_content	This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
ELEMENT_NODE	An element node
ATTRIBUTE_NODE	An attribute node
TEXT_NODE	A text node

first_element_child	Returns the first child element node of this element. null if this element has no child elements.
last_element_child	Returns the last child element node of this element. null if this element has no child elements.
previous_element_sibling	Returns the previous sibling element node of this element. null if this element has no element sibling nodes that come before this one in the document tree.
next_element_sibling	Returns the next sibling element node of this element. null if this element has no element sibling nodes that come after this one in the document tree.
child_element_count	Returns the current number of element nodes that are children of this element. 0 if this element has no child nodes that are of nodeType 1.
children	Returns the child elements of current element.
inner_html	Returns a fragment of HTML or XML that represents the element’s contents. Can be set, to replace the contents of the element with nodes parsed from the given string.
outer_html	Returns a fragment of HTML or XML that represents the element and its contents. Can be set, to replace the element with nodes parsed from the given string.
shadow_root	Returns shadowRoot stored on this element or null if it’s closed.
owner_svg_element	The nearest ancestor ‘svg’ element. Null if the given element is the outermost svg element.
viewport_element	The element which established the current viewport. Often, the nearest ancestor ‘svg’ element. Null if the given element is the outermost svg element.

Methods

Method	Description
add_event_listener	This method allows the registration of event listeners on the event target.
add_event_listener	This method allows the registration of event listeners on the event target.
remove_event_listener	This method allows the removal of event listeners from the event target. If an `IEventListener` is removed from an `EventTarget` while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
remove_event_listener	This method allows the removal of event listeners from the event target. If an `IEventListener` is removed from an `EventTarget` while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
clone_node	Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
clone_node	Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
toggle_attribute	If force is not given, “toggles” qualifiedName, removing it if it is present and adding it if it is not present. If force is true, adds qualifiedName. If force is false, removes qualifiedName.
toggle_attribute	If force is not given, “toggles” qualifiedName, removing it if it is present and adding it if it is not present. If force is true, adds qualifiedName. If force is false, removes qualifiedName.
get_platform_type	This method is used to retrieve ECMAScript object Type.
dispatch_event	This method allows the dispatch of events into the implementations event model.
has_child_nodes	Returns whether this node has any children.
normalize	Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a “normal” form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used. If the parameter “normalize-characters” of the DOMConfiguration object attached to the Node.ownerDocument is true, this method will also fully normalize the characters of the Text nodes.
is_equal_node	Tests whether two nodes are equal. This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
is_same_node	Returns whether this node is the same node as the given one. This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
lookup_prefix	Look up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method. See Namespace Prefix Lookup for details on the algorithm used by this method.
lookup_namespace_uri	Look up the namespace URI associated to the given prefix, starting from this node.
is_default_namespace	This method checks if the specified namespaceURI is the default namespace or not.
insert_before	Inserts the node before the existing child node child. If child is null, insert node at the end of the list of children. If child is a DocumentFragment object, all of its children are inserted, in the same order, before child. If the child is already in the tree, it is first removed.
replace_child	Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.
remove_child	Removes the child node indicated by oldChild from the list of children, and returns it.
append_child	Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.
get_attribute_names	Returns the attribute names of the element as an Array of strings. If the element has no attributes it returns an empty array.
has_attributes	Returns whether this node (if it is an element) has any attributes
get_attribute	Retrieves an attribute value by name.
get_attribute_ns	Retrieves an attribute value by local name and namespace URI.
set_attribute	Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter
set_attribute_ns	Adds a new attribute. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter.
remove_attribute	Removes an attribute by name.
remove_attribute_ns	Removes an attribute by local name and namespace URI.
has_attribute	Returns true when an attribute with a given name is specified on this element or has a default value, false otherwise.
has_attribute_ns	Returns true when an attribute with a given local name and namespace URI is specified on this element or has a default value, false otherwise.
get_attribute_node	Retrieves an attribute node by name.
set_attribute_node	Adds a new attribute node. If an attribute with that name (nodeName) is already present in the element, it is replaced by the new one.
remove_attribute_node	Removes the specified attribute node.
get_attribute_node_ns	Retrieves an Attr node by local name and namespace URI.
set_attribute_node_ns	Adds a new attribute. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one.
get_elements_by_tag_name	Returns a NodeList of all descendant Elements with a given tag name, in document order.
get_elements_by_tag_name_ns	Returns a NodeList of all the descendant Elements with a given local name and namespace URI in document order.
remove	Removes this instance.
query_selector_all	Returns a NodeList of all the Elements in document, which match selector
query_selector	Returns the first Element in document, which match selector
attach_shadow	Creates shadow root and attaches it to current element.
get_elements_by_class_name	Returns a live NodeList object containing all the elements in the document that have all the classes specified in argument. http://www.w3.org/TR/dom/
get_b_box	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.
get_ctm	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.
get_screen_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 CSS2 definition of a “pixel” can be used instead. Note that null is returned if this element is not hooked into the document tree. This method would have been more aptly named as getClientCTM, but the name getScreenCTM is kept for historical reasons.
get_equivalent_path	Returns a new instance instance of the `SVGPathSegList` which represents `SVGGeometryElement` as path segments.
get_equivalent_path_as_i_path	Returns the equivalent path as an instance of `IPath`.
get_total_length	Returns the user agent’s computed value for the total length of the path using the user agent’s distance-along-a-path algorithm, as a distance in the current user coordinate system.
get_point_at_length	Returns the (x,y) coordinate in user space which is distance units along the path, utilizing the user agent’s distance-along-a-path algorithm.
