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.

The following example shows how to add fonts to an XpsDocument.

' -------------------------- AddPageResources ----------------------------
Private Function AddPageResources(ByVal fixedPageWriter As IXpsFixedPageWriter) As Dictionary(Of String, List(Of XpsResource))
    ' Collection of all resources for this page.
    '   Key: "XpsImage", "XpsFont"
    '   Value: List of XpsImage or XpsFont
    Dim resources As New Dictionary(Of String, List(Of XpsResource))()

    ' Collections of images and fonts used in the current page.
    Dim xpsImages As New List(Of XpsResource)()
    Dim xpsFonts As New List(Of XpsResource)()

    Try
        Dim xpsImage As XpsImage
        Dim xpsFont As XpsFont

        ' Add, Write, and Commit image1 to the current page.
        xpsImage = fixedPageWriter.AddImage(XpsImageType.JpegImageType)
        WriteToStream(xpsImage.GetStream(), image1)
        xpsImage.Commit()
        xpsImages.Add(xpsImage) ' Add image1 as a required resource.

        ' Add, Write, and Commit font 1 to the current page.
        xpsFont = fixedPageWriter.AddFont()
        WriteObfuscatedStream(xpsFont.Uri.ToString(), xpsFont.GetStream(), font1)
        xpsFont.Commit()
        xpsFonts.Add(xpsFont) ' Add font1 as a required resource.

        ' Add, Write, and Commit image2 to the current page.
        xpsImage = fixedPageWriter.AddImage(XpsImageType.TiffImageType)
        WriteToStream(xpsImage.GetStream(), image2)
        xpsImage.Commit()
        xpsImages.Add(xpsImage) ' Add image2 as a required resource.

        ' Add, Write, and Commit font2 to the current page.
        xpsFont = fixedPageWriter.AddFont(False)
        WriteToStream(xpsFont.GetStream(), font2)
        xpsFont.Commit()
        xpsFonts.Add(xpsFont) ' Add font2 as a required resource.

        ' Return the image and font resources in a combined collection.
        resources.Add("XpsImage", xpsImages)
        resources.Add("XpsFont", xpsFonts)
        Return resources
    Catch xpsException As XpsPackagingException
        Throw xpsException
    End Try
End Function ' end:AddPageResources()
