    Question Display pixel value

    I'm planning of loading a black and white 10X10 gif
    then I want to print value of each pixel (like black 1; white 0)
    I have coded till this much. after grabbing the pixels using my object called pixelGrabber,
    I read in oracle that the method grabPixels() returns only an object. which class's object is it returning?
    how can I print each pixels' data?

    Please do help.
    I am new in java I cant understand very complex stuff.

    public static void main(String args[])throws Exception
    BufferedImage img;
    img = File("abc.gif"));
    int Width = img.getWidth();
    int Height = img.getHeight();
    PixelGrabber pixelGrabber=new PixelGrabber(img,0,0,Width,Height,false);

    Default Re: Display pixel value

    There is no need to use pixel grabber. BufferedImage has a method - getRGB() which returns an RGB int value of the pixel at the supplied coordinates. You can use the Color methods to interrogate the returned int value.

    Poor planning on your part does not constitute an emergency on my part
