How to get a byte[] data from an Image object?

Question

I have Image objects created from images stored in the mobile memory. I want to get the byte[] value of these Image objects. How to achieve that ?

Answer 1

You can use below method to convert the com.sun.lwuit.Image to byte[].

public byte[] imageProcessing(String imageName, Image image) {

        int[] rgb = image.getRGB();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        DataOutputStream dos = new DataOutputStream(baos);
        dos.writeUTF(imageName);

        for (int i = 0; i < rgb.length; i++) {
            dos.writeInt(rgb[i]);
        }

   return baos.toByteArray();
 }
