    Default 2d array to image

    Hello,

    I.ve problem with java image processing.I've to convert 2d array into image.I'm using the loadPixels function, but it doesen't work.The Image is never shown on the label.
    Please help, here is the code of the loadPixels function:

    Java Code:
    public static void loadPixels(JLabel label, int[][] pixels) {
    		// 1. convert to 1-d array
    		int width  = pixels.length;
    		int height = pixels[0].length; 
    		int i=0;    // index into new pixarray
    		int[] pixarray = new int[width*height];
    		for (int y=0; y<height; y++)
    		for (int x=0; x<width;  x++)
    			// these are stored y-major!
    			pixarray[i++] = pixels[x][y];
    		// 2. convert 1-d array into Image*/
    		MemoryImageSource source = new MemoryImageSource(width,height,pixarray,0,width);
    		
    	 imageto=label.createImage(source);   // imageto is declared in the top of the class as "private static Image"
    		
    		// 3. store Image in the JLabel
    		ImageIcon imic=new ImageIcon(imageto);
    		
    		//imic=image;
    		label.setIcon(imic);		
    	}
    Any help would be greatly appreciated.

    Thanks,

    Nina
