To add a watermark to the HTML/JPG/PNG/PDF output, follow these steps:

Create an instance of the HtmlViewOptions class (or PngViewOptions, or JpgViewOptions, or PdfViewOptions);
Create a Watermark object and populate its properties;
Call the setWatermark method of the HtmlViewOptions (or PngViewOptions, or JpgViewOptions, or PdfViewOptions) class and specify the object created on step 2;
Call the Viewer.view() method.

The following code snippet shows how to apply the watermark to the output pages.

Java

import com.groupdocs.viewer.Viewer;
import com.groupdocs.viewer.options.HtmlViewOptions;
import com.groupdocs.viewer.options.Watermark;
// ...

try (Viewer viewer = new Viewer("sample.docx")) {
    // Create an HTML file.
    HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
    // Add watermark.
    viewOptions.setWatermark(new Watermark("This is a watermark"));

    viewer.view(viewOptions);
}
