Remarks

The XpsFont class has no public constructor.

Use the AddFont method to add a font and obtain a reference to it in a new document.

Use the GetFont method to obtain a font reference in an existing document.

Based on settings of XpsSerializationManager and XpsPackagingPolicy, such as FontSubsetterCommitPolicies and PackageInterleavingOrder, the flush operation of the Commit method of the XpsFont class may be delayed until the whole XpsDocument is closed.

Properties

IsObfuscated	Gets a value that indicates whether the font is obfuscated.
IsRestricted	Gets or sets a value that indicates whether text that uses this font can be modified.
Uri	Gets or sets the uniform resource identifier (URI) of the part. (Inherited from XpsPartBase)

Methods

Commit()	Commits all changes and flushes the resource to the document package. (Inherited from XpsResource)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetStream()	When overridden in a derived class, returns the I/O stream for reading or writing the resource. (Inherited from XpsResource)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ObfuscateFontData(Byte[], Guid)	Obfuscates the font typeface data.
RelativeUri(Uri)	Returns the URI of the resource that is relative to a specified absolute URI. (Inherited from XpsResource)
ToString()	Returns a string that represents the current object. (Inherited from Object)
