    I need to make a PDF in landscape format.

    <script type="text/javascript">
    $(function () {
        var doc = new jsPDF();
        var specialElementHandlers = {
            '#editor': function (element, renderer) {
                return true;
            }
        };
        $('#cmd').click(function () {
            doc.fromHTML($('#content').html(), 15, 15, {
                'width': 170,
                'elementHandlers': specialElementHandlers
            });
            doc.save('sample-file.pdf');
        });
    });
</script>

    Reset to default 9

    I found it out. It is so simple :) The first Param is for landscape in jsPDF() which is l for landscape.

    var pdf = new jsPDF('l', 'mm', [297, 210]); //The first Param is for landscape or portrait

    app.ponent.ts

    @ViewChild('pdfContent') pdfContent: ElementRef;

 async capture() {

// var doc = new jspdf("p", "pt", "a4");  // For Portrait

var doc = new jspdf('l', 'pt', "a4");  // For landscape
//code


})

    app.ponent.html

     <div class="col-md-12" class="tablejoin" #pdfContent id = 
 "entireTable" >
<table> .. </table>
</div>

    use the below code for portrait mode.

        var doc = new jsPDF('l', 'mm', 'a4'); // optional parameters
    doc.addImage(img/imgdata, 'PNG', 10, 10, 280, 180);
    doc.save("new.pdf");

    Configure dimension while adding the image or data for pdf.
