Enable layered rendering

When rendering into HTML GroupDocs.Viewer renders text and graphics as a single layer that improves performance and reduces HTML document size. To improve content positioning when rendering multi-layered PDF document GroupDocs.Viewer for Java provides setEnableLayeredRendering(…) option that enables rendering of text and graphics according to z-order in original PDF document when rendering into HTML.

Following code sample demonstrates how to enable layered rendering.

    try (Viewer viewer = new Viewer("sample.pdf")) {
        HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
