Method

byte[]bufferedImageToByte(BufferedImage image, String format)
buffered Image To Byte 
final ByteArrayOutputStream bos = new ByteArrayOutputStream();
ImageIO.write(image, format, bos);
return bos.toByteArray();
byte[]bufferedImageToByte(BufferedImage originalImage)
buffered Image To Byte 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(originalImage, "jpg", baos);
baos.flush();
byte[] imageInByte = baos.toByteArray();
baos.close();
return imageInByte;
byte[]bufferedImageToByteArray(BufferedImage bufferedImage)
Convert BufferedImage to byte array 
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(bufferedImage, IMAGE_FORMAT, baos);
baos.flush();
byte[] imageInByte = baos.toByteArray();
baos.close();
return imageInByte;
ByteBufferbufferedImageToByteArray(BufferedImage image)
buffered Image To Byte Array 
PixelGrabber pg = new PixelGrabber(image, 0, 0, -1, -1, true);
pg.grabPixels();
int[] pixels = (int[]) pg.getPixels();
ByteBuffer out = ByteBuffer.allocate(pixels.length * 4);
out.order(ByteOrder.nativeOrder());
for (int i = 0; i < pixels.length; i++) {
    out.putInt(pixels[i]);
out.flip();
return out;
byte[]bufferedImageToByteArray(BufferedImage img)
Converts a BufferedImage into a byte[]. 
ByteArrayOutputStream os = new ByteArrayOutputStream();
ImageIO.write(img, "JPEG", os);
return os.toByteArray();
byte[]bufferedImageToBytes(final BufferedImage bufferedImage, final ImageWriter imageWriter, final ImageWriteParam imageWriteParameter)
Converts a BufferedImage into bytes using a specific image writer, and image write parameters
