OfficeMath

OfficeMath class

Represents an Office Math object such as function, equation, matrix or alike. Can contain child elements including runs of mathematical text, bookmarks, comments, other OfficeMath instances and some other nodes.

virtual Document { get; }	Gets the document to which this node belongs.
FirstChild { get; }	Gets the first child of the node.
HasChildNodes { get; }	Returns `true` if this node has any child nodes.
override IsComposite { get; }	Returns `true` as this node can have child nodes.
Justification { get; set; }	Gets/sets Office Math justification.
LastChild { get; }	Gets the last child of the node.
MathObjectType { get; }	Gets type `MathObjectType` of this Office Math object.
NextSibling { get; }	Gets the node immediately following this node.
override NodeType { get; }	Returns OfficeMath.
ParentNode { get; }	Gets the immediate parent of this node.
ParentParagraph { get; }	Retrieves the parent `Paragraph` of this node.
PreviousSibling { get; }	Gets the node immediately preceding this node.
Range { get; }	Returns a `Range` object that represents the portion of a document that is contained in this node.

RemoveSmartTags()	Removes all `SmartTag` descendant nodes of the current node.
SelectNodes(string)	Selects a list of nodes matching the XPath expression.
SelectSingleNode(string)	Selects the first `Node` that matches the XPath expression.
ToString(SaveFormat)	Exports the content of the node into a string in the specified format.
ToString(SaveOptions)	Exports the content of the node into a string using the specified save options.

Remarks

In this version of Aspose.Words, OfficeMath nodes do not provide public methods and properties to create or modify a OfficeMath object. In this version you are not able to instantiate Math nodes or modify existing except deleting them.

OfficeMath can only be a child of Paragraph.

Examples

Shows how to set office math display formatting.

Document doc = new Document(MyDir + "Office math.docx");

OfficeMath officeMath = (OfficeMath)doc.GetChild(NodeType.OfficeMath, 0, true);

// OfficeMath nodes that are children of other OfficeMath nodes are always inline.
// The node we are working with is the base node to change its location and display type.
Assert.AreEqual(MathObjectType.OMathPara, officeMath.MathObjectType);
Assert.AreEqual(NodeType.OfficeMath, officeMath.NodeType);
Assert.AreEqual(officeMath.ParentNode, officeMath.ParentParagraph);

// Change the location and display type of the OfficeMath node.
officeMath.DisplayType = OfficeMathDisplayType.Display;
officeMath.Justification = OfficeMathJustification.Left;

doc.Save(ArtifactsDir + "Shape.OfficeMath.docx");
