I am having problems with Html2canvas render as i want to take multiple screenshots of an image and send the same to the selected contacts in a sequence but Html2canvas is rendering images in a delayed and unsequential way, which in return is not able to send the image to corresponding selected contact. Below is my code it is running successfully but the delay and unsequential output is creating a lot of problem.

```
function printCards(calle, eventID){
    var cards = new Array();

    var checkboxArray = $("input[name='contactsParty']:checked");

    $('#inviteContactName').html($(checkboxArray[0]).parent().prev().children('label').text());

        //  iterating selected checkboxes for invitation
        checkboxArray.each(function(index, value){

            //  getting name of next contact selected
            var name = $(checkboxArray[index+1]).parents().eq(1).find('label').text();

            //  Getting invitation card
            var invitationCard;
            $.when(invitationCard = getImage(name)).promise().done(function(){
                //  saving the printed invitation
                cards.push(invitationCard);
            });

        });

    return cards;   

}

//  printing invitation card with contact name
function getImage(name){

    var invitationCard = new Image();

        html2canvas($("#invitationData"), {
//          logging : true,
            onrendered: function(canvas) {
                //  For image`enter code here`
                var ctx=canvas.getContext("2d");
//              ctx.webkitImageSmoothingEnabled = false;
//              ctx.mozImageSmoothingEnabled = false;
                ctx.imageSmoothingEnabled = false;

                var convertedImage;
                $.when(convertedImage = canvas.toDataURL('image/jpg')).promise().done(function(){
                    invitationCard.src = convertedImage;
                    $('#inviteContactName').html(name);
                });  
//              setTimeout(function (){}, 500);
            }

        });

    return invitationCard;

}
