byte[]toByteArray(BufferedImage image, float quality)
to Byte Array 
try {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    if (quality == -1)

    else
        write(image, quality, out); 
    return out.toByteArray();
} catch (IOException e) {
...
byte[]toByteArray(BufferedImage image, String extension)
Saves image into byte array. 
if (image != null) {

    try {
        ImageIO.write(image, extension, baos);
    } catch (IOException e) {
        throw new IllegalStateException(e.toString());
    byte[] b = baos.toByteArray();
...
byte[]toByteArray(BufferedImage image, String formatName)
to Byte Array 
ByteArrayOutputStream os = new ByteArrayOutputStream();

byte[] data = os.toByteArray();
os.close();
return data;
byte[]toByteArray(BufferedImage img, String imageFileType)
to Byte Array

} catch (Throwable e) {
    throw new RuntimeException();
byte[]toByteArray(BufferedImage org)
Converts a BufferedImage to a byte array. 
if (org != null) {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ImageIO.write(org, "jpg", baos);
    baos.flush();
