The answer is here: http://odyniec.net/projects/imgareaselect/examples-callback.html - with a live example !!
function preview(img, selection) {
var scaleX = 100 / (selection.width || 1);
var scaleY = 100 / (selection.height || 1);
$('#ferret + div > img').css({
width: Math.round(scaleX * 400) + 'px',
height: Math.round(scaleY * 300) + 'px',
marginLeft: '-' + Math.round(scaleX * selection.x1) + 'px',
marginTop: '-' + Math.round(scaleY * selection.y1) + 'px'
});
}
$(document).ready(function () {
$('<div><img src="ferret.jpg" style="position: relative;" /><div>')
.css({
float: 'left',
position: 'relative',
overflow: 'hidden',
width: '100px',
height: '100px'
})
.insertAfter($('#ferret'));
$('#ferret').imgAreaSelect({ aspectRatio: '1:1', onSelectChange: preview });
});
Hope I can help. :)
