  public abstract void fontSaving(FontSavingArgs args)
                               throws java.lang.Exception

  Called when Aspose.Words is about to save a font resource.

  Example:

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

  public void saveExportedFonts() throws Exception {
      Document doc = new Document(getMyDir() + "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();
      {
          options.setExportFontResources(true);
          options.setFontSavingCallback(new HandleFontSaving());
      }
  
      // The callback will export .ttf files, and save them alongside the output document.
      doc.save(getArtifactsDir() + "HtmlSaveOptions.SaveExportedFonts.html", options);
  
      File[] fontFileNames = new File(getArtifactsDir()).listFiles((d, name) -> name.endsWith(".ttf"));
  
      for (File fontFilename : fontFileNames) {
          System.out.println(fontFilename.getName());
      }
  
  }
