How to send imagebuffer over socket?

How to send bufferеdimage over socket?

[Norm]

What have you tried? How about writeObject()
What does the receiving side want? A java object or the bytes of an image?

[Tolls]

I'm not sure BufferedImage is serializable, so writeObject() won't work.

[Norm]

Good point.

Send over the RGB data (just an int array) and the type of the BufferedImage and its dimensions (just three single ints) and construct a new BufferedImage on the other side.

kind regards,

yeah, and those could be stored in a object and send it, instead of sending four objects.

public class BufferedImageInformation implements java.io.Serializable
{
	private static final long serialVersionUID = 1L;
	private byte[] pixels;
	private int height;
	private int width;
	private int type;

	private BufferedImageInformation () {}

	public static BufferedImageInformation  createInstance (BufferedImage image)
	{
		BufferedImageInformation  bii = new BufferedImageInformation ();
		bii.pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
		bii.height = image.getHeigth();
		bii.width
		...
		//You get the rest
	}

	public static BufferedImage decode (BufferedImageInformation bii)
	{
		...
		//Decode it into a BufferedImage
	}
}
