I use already jsPDF to download note for student but I can't fix this problem. If data has no image jspdf work correctly but when I add image with some text pdf is downloaded empty. How can I fix it?

this is js code

function NoteToPdf(Id) {
    debugger
    $.ajax({
        type: "POST",
        url: '/Notes/GetNotesById/' + Id,
        success: function (data) {
            debugger
            var Content = data['data'][0]['Content'];
            var Title = data['data'][0]['Title'];
            var pdf = new jsPDF();
            debugger
            var leftMargin = 15, topMargin = 15, width = 170;
            var HTML = $(Content).html();
            pdf.fromHTML(HTML, leftMargin, topMargin, {
                'width': width
            });
            pdf.save(Title);
        },
        error: function (request, status, error) {
            swal.fire("error");
        }
    });
}
