        file = new File(myProjectActualPath + "myImage.png");
        ImageIO.write(rendImage, "png", file);
        fis2 = new BufferedInputStream(new FileInputStream(myProjectActualPath + "myImage.png"));

    } catch (IOException ioe) {
        System.out.println("IOException :: " + ioe);
    } catch (Exception e) {
        System.out.println("Exception :: " + e);
    }
    image.flush();
}
