Examples

Shows how to work with CSS stylesheets that an HTML conversion creates.

test('ExternalCssFilenames', () => {
  let doc = new aw.Document(base.myDir + "Rendering.docx");

  // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
  // to modify how we convert the document to HTML.
  let options = new aw.Saving.HtmlSaveOptions();

  // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
  // accompany a saved HTML document with an external CSS stylesheet file.
  options.cssStyleSheetType = aw.Saving.CssStyleSheetType.External;

  // Below are two ways of specifying directories and filenames for output CSS stylesheets.
  // 1 -  Use the "CssStyleSheetFileName" property to assign a filename to our stylesheet:
  options.cssStyleSheetFileName = base.artifactsDir + "SavingCallback.ExternalCssFilenames.css";

  // 2 -  Use a custom callback to name our stylesheet:
  options.cssSavingCallback =
    new CustomCssSavingCallback(base.artifactsDir + "SavingCallback.ExternalCssFilenames.css", true, false);

  doc.save(base.artifactsDir + "SavingCallback.ExternalCssFilenames.html", options);
});
