java如何将图像作为文本从服务器转换为javascript图像？

Question

我将图像作为ImageIO输出写入servlet

BufferedImage combined = null;


      int w = 1080;
      int h = 960;
      combined = new BufferedImage(w, h, 1);

      Graphics g = combined.getGraphics();
      g.drawImage(image, 0, 0, null);
      for (int size = 0; size < imageList.size(); size++) {
        g.drawImage((Image)imageList.get(size), 0, 0, null);
      }
      g.dispose();
      response.addHeader("Access-Control-Allow-Origin", "*");
      OutputStream out = response.getOutputStream();
      response.setContentType("text/plain");

      ImageIO.write(combined, "png", out);
      combined.flush();
      response.setStatus(200);
      out.close();

如何从javascript中读取该图像并在HTML页面中显示
