    			float sWidth = imgWidth-w;
    			float sFactor = (sWidth/imgWidth);
    			imgWidth = w;
    			imgHeight = (int) (imgHeight-(imgHeight*sFactor));
    		//Find the right hight 
    		if(imgHeight > h){
    			float sHeight = imgHeight-h;
    			float sFactor = sHeight/imgHeight;
    			imgHeight = h;
    			imgWidth = (int) (imgWidth-(imgWidth*sFactor));
    		BufferedImage resizedImg = new BufferedImage(imgWidth, imgHeight, BufferedImage.TYPE_INT_ARGB);
    		Graphics2D g2 = resizedImg.createGraphics();
    		g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
