<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.3.1/css/bootstrap.css">
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<link type="text/css" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/south-street/jquery-ui.css" rel="stylesheet">
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="asset/jquery.signature.min.js"></script>
<link rel="stylesheet" type="text/css" href="asset/jquery.signature.css">
<style>
.kbw-signature { width: 400px; height: 200px;}
#sig canvas{
width: 100% !important;

}
</style>

<div class="container">
<form method="POST" action="upload.php">

</div>
<br/>
<button class="btn btn-success">Submit</button>
</form>
</div>
<script type="text/javascript">
var sig = $('#sig').signature({syncField: '#signature64', syncFormat: 'PNG'});

$image_type_aux = explode("image/", $image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = base64_decode($image_parts[1]);
$file = $folderPath . uniqid() . '.'.$image_type;
file_put_contents($file, $image_base64);
