Html2Canvas Screenshot is a Vaadin add-on that makes taking screenshots of your clients' UIs extremely easy and with no Java applet or plugin required. You get the data URL, raw image bytes, and MIME type of the image as a response in a listener callback. The current version utilizes html2canvas 0.4.1.

Sample code

final Screenshot screenshot = new Screenshot();
screenshot.addScreenshotListener(new ScreenshotListener() {
    public void screenshotComplete(ScreenshotImage image) {
        Window window = new Window("Here's your screenshot", new Image(null, new ExternalResource(image.getDataURL())));
        window.setWidth("80%");
        window.setHeight("80%");
        addWindow(window);
    }
});
screenshot.takeScreenshot();
final Screenshot component = Screenshot.newBuilder()
  .withAllowTaint(true)
  .withBackground("#f00")
  .withHeight(768)
  .withWidth(1024)
  .withLogging(true)
  .withMimeType(ScreenshotMimeType.JPEG)
  .build();
component.addScreenshotListener(new ScreenshotListener() {
    public void screenshotComplete(ScreenshotImage image) {
        Window window = new Window("Here's your screenshot", new Image(null, new ExternalResource(image.getDataURL())));
        window.setWidth("80%");
        window.setHeight("80%");
        addWindow(window);
    }
});
component.takeScreenshot();
