FontFileName

FontSavingArgs.FontFileName property

Gets or sets the file name (without path) where the font will be saved to.

public string FontFileName { get; set; }

Remarks

This property allows you to redefine how the font file names are generated during export to HTML.

When the event is fired, this property contains the file name that was generated by Aspose.Words. You can change the value of this property to save the font into a different file. Note that file names must be unique.

Aspose.Words automatically generates a unique file name for every embedded font when exporting to HTML format. How the font file name is generated depends on whether you save the document to a file or to a stream.

When saving a document to a file, the generated font file name looks like <document base file name>.<original file name><optional suffix>.<extension>.

When saving a document to a stream, the generated font file name looks like Aspose.Words.<document guid>.<original file name><optional suffix>.<extension>.

FontFileName must contain only the file name without the path. Aspose.Words determines the path for saving using the document file name, the FontsFolder and FontsFolderAlias properties.

Examples

Shows how to define custom logic for exporting fonts when saving to HTML.

public void SaveExportedFonts()
{
    Document doc = new Document(MyDir + "Rendering.docx");

    // Configure a SaveOptions object to export fonts to separate files.
    // Set a callback that will handle font saving in a custom manner.
    HtmlSaveOptions options = new HtmlSaveOptions
    {
        ExportFontResources = true,
        FontSavingCallback = new HandleFontSaving()
    };

    // The callback will export .ttf files and save them alongside the output document.
    doc.Save(ArtifactsDir + "HtmlSaveOptions.SaveExportedFonts.html", options);

    foreach (string fontFilename in Array.FindAll(Directory.GetFiles(ArtifactsDir), s => s.EndsWith(".ttf")))
    {
        Console.WriteLine(fontFilename);
    }

}

/// <summary>
/// Prints information about exported fonts and saves them in the same local system folder as their output .html.
/// </summary>
public class HandleFontSaving : IFontSavingCallback
{
    void IFontSavingCallback.FontSaving(FontSavingArgs args)
    {
        Console.Write($"Font:\t{args.FontFamilyName}");
        if (args.Bold) Console.Write(", bold");
        if (args.Italic) Console.Write(", italic");
        Console.WriteLine($"\nSource:\t{args.OriginalFileName}, {args.OriginalFileSize} bytes\n");

        // We can also access the source document from here.
        Assert.True(args.Document.OriginalFileName.EndsWith("Rendering.docx"));

        Assert.True(args.IsExportNeeded);
        Assert.True(args.IsSubsettingNeeded);

        // There are two ways of saving an exported font.
        // 1 -  Save it to a local file system location:
        args.FontFileName = args.OriginalFileName.Split(Path.DirectorySeparatorChar).Last();

        // 2 -  Save it to a stream:
        args.FontStream =
            new FileStream(ArtifactsDir + args.OriginalFileName.Split(Path.DirectorySeparatorChar).Last(), FileMode.Create);
        Assert.False(args.KeepFontStreamOpen);
    }
}
