"format": $("#barcodeType").val(),
"background": $("#background-color").val(),
"lineColor": $("#line-color").val(),
"fontSize": parseInt($("#bar-fontSize").val()),
"height": parseInt($("#bar-height").val()),
"width": $("#bar-width").val(),
"margin": parseInt($("#bar-margin").val()),
"textMargin": parseInt($("#bar-text-margin").val()),
"displayValue": $(".display-text.btn-primary").val() == "true",
"font": $("#font").val(),
"fontOptions": $(".font-option.btn-primary").map(function(){return this.value;}).get().join(" "),
"textAlign": $(".text-align.btn-primary").val(),
"valid":
function(valid){
if(valid){
$("#barcode").show();

else{
$("#barcode").hide();
$("#invalid").show();
}
}

$(function(){
$(".btn-download").click(function(){
var svgXml = $('.svg-wrap').html();
var dataUrl = 'data:image/svg+xml;base64,' + window.btoa(unescape(encodeURIComponent(svgXml)));
var canvas = document.createElement('canvas');
canvas.width = $('.svg-wrap svg').width();
canvas.height = $('.svg-wrap svg').height();
var image = new Image();
image.src = dataUrl;
var context = canvas.getContext('2d');
image.onload = function() {
context.drawImage(image, 0, 0);
var a = document.createElement("a");
a.download = "toolfk.com-"+Math.random()+".png";
a.href = canvas.toDataURL("image/png");
a.click();
};
});
});
