I have a div which I'm applying the jSignature plugin to with
var $sigdiv = $(".jsig")
$sigdiv.jSignature() // inits the jSignature widget.
I have a button to capture this to base64 then pass it to PHP to create the image on the server.
$sig=$("#signature");
alert($sig.jSignature("getData"));
getData returns base64 for a PNG but I need a jpeg and I can't get it to work. Has anybody come across a workaround please.
