Getting wrong values!

Question

Hi,
In the following code I'm trying to read the pixels of a bufered image into an array then use these pixels in another process, what I have figured that after reading the pixels I've got two pixel values (-1, -16777216) whereas I'm reading a binary image and suppose to have 0 and 1!!
Where is the wrong in this code ?
// Read histogram image in image of type  Image
Image Histimage =  Toolkit.getDefaultToolkit().createImage(bi[0].getSource());
               // First get the Width and Hieght of origenal histogram
                   int ImgW = Histimage.getWidth(this);
                   int ImgH = Histimage.getHeight(this);
                   pixelInput  = new int[ImgW*ImgH];
                  PixelGrabber pg = new PixelGrabber(Histimage, 0, 0, ImgW, ImgH,pixelInput, 0, ImgW);
            try {
               pg.grabPixels();
            catch(InterruptedException e)
               System.err.println("Grabbing Interrupted");
               e.printStackTrace();

" Print those values out in hex and then interpret
them as AARRGGBB (alpha, red, green, blue). One's
white, and the other's black.
Ok. But how to do that ?Take a look at Integer.toHexString(int i)
