1)Create gradient Layers for min_trackImage and max_trackImage respectively.
2)Set layers frame to slider min_trackImage frame and max_trackImage properly along with changing x position of gradient layer.
3)Set its startPoint to Left and endPoint to right.
4)Using QuartzCore concept we set layers corner radius to 5.0;
