public static byte[] getImageBytes(BufferedImage src,
                                   byte[] output)

Get raw bytes from ARGB BufferedImage.

Parameters:

src - ARGB BufferImage

output - output buffer, if not null and if its length is at least image's (width * height) * 4, method will put bytes in it.

Returns:

raw bytes or null if src is not an ARGB BufferedImage
