ICssSavingCallback

public interface ICssSavingCallback

Implement this interface if you want to control how Aspose.Words saves CSS (Cascading Style Sheet) when saving a document to HTML.

Examples:

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


 public void externalCssFilenames() throws Exception {
     Document doc = new Document(getMyDir() + "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.
     HtmlSaveOptions options = new HtmlSaveOptions();

     // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
     // accompany a saved HTML document with an external CSS stylesheet file.
     options.setCssStyleSheetType(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.setCssStyleSheetFileName(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.css");

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

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

 /// Sets a custom filename, along with other parameters for an external CSS stylesheet.

         mKeepCssStreamOpen = keepCssStreamOpen;
