Can you please provide complete code listing where we get bytes from Image (which I store in DB)

The convert those bytes to Image

I have these methods:

    public byte[] getBytesFromImage(com.codename1.ui.Image image) {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        byte[] BytesFromImage = new byte[0];
        try {
            if (image != null) {
                ImageIO.getImageIO().save(image, outputStream, ImageIO.FORMAT_PNG, 1f);
                BytesFromImage = outputStream.toByteArray();
            }
        } catch (Exception e) {
            e.printStackTrace();
            MyLog.e(e);
        }
        return BytesFromImage;
    }

    public Image getImageFromBytes(byte[] img) {
        Image image = null;
        try {
            int width = 978;
            int height = 550;
            image = Image.createImage(img, 0, img.length);
            if (image.getHeight() > height || image.getWidth() > width) {
                image = image.scaled(height, width);
            }
        } catch (Exception e) {
            e.printStackTrace();
            MyLog.e(e);
        }
        return image;
    }

java.lang.IllegalArgumentException: Width (-35) and height (-20) cannot be <= 0
