        bready(function() {
            use(["jquery.Jcrop", "jquery.Jcrop"], function() {
                var jcrop_api;
                var bounds, boundx, boundy;

                $('#cropbox').Jcrop({
                    onChange: showPreview,
                    onSelect: showPreview,
                    aspectRatio: 1
                }, function() {
                    jcrop_api = this;
                    bounds = jcrop_api.getBounds();
                    boundx = bounds[0];
                    boundy = bounds[1];
                });

                function showPreview(coords) {
                    if (parseInt(coords.w) > 0) {
                        var rx = 100 / coords.w;
                        var ry = 100 / coords.h;

                        $('#preview').css({
                            width: Math.round(rx * boundx) + 'px',
                            height: Math.round(ry * boundy) + 'px',

                        });
                    }
                };
            });
        });
    </script>
</head>
<body>
    <h1>Jcrop - Aspect ratio w/ preview pane</h1>
