Javascript / jquery download image

I want to know how i can handle to download a image that come from a header response:

Here a sketch of my script:

$.get("{!!route('gerarFlyerImage')!!}",dados).done(function(data){

    console.log(data);
    saveData(data, 'filename.png');    
})


function saveData(blob, fileName) // does the same as FileSaver.js
{
    var a = document.createElement("a");
    document.body.appendChild(a);
    a.style = "display: none";

    var url = window.URL.createObjectURL(blob);
    a.href = url;
    a.download = fileName;
    a.click();
    window.URL.revokeObjectURL(url);
}

But saveData() not working some idea?

Try this - Download images from your url.

Demo: https://jsfiddle.net/usmanmunir/fx8Lzt4g/18/

JS Script

function downloadFile(fileName) {
    $.ajax({
        url: '{!!route('gerarFlyerImage')!!}',
        method: 'GET',
        data: dados,
        xhrFields: {
            responseType: 'blob'
        },
        success: function (data) {
            var a = document.createElement('a');
            var url = window.URL.createObjectURL(data);
            a.href = url;
            a.download = fileName;
            document.body.append(a);
            a.click();
            a.remove();
            window.URL.revokeObjectURL(url);
        }
    });
}

Hope this helps.
