There is no build-in function for such thing. But you can make that:

1. Use HTML template to print out your view and than pass that content to TCPDF

Example

$pdf->AddPage();

$html = $this->renderPartial('view', ['params'], true);

// output the HTML content
$pdf->writeHTML($html, true, 0, true, 0);
$pdf->lastPage();
$pdf->Output('example_021.pdf', 'I');

2. Make image from current view and pass that image to TCPDF.

Example

html2canvas(document.getElementById('area')).then(function(canvas) {
    var data = canvas.toDataURL();

    $.ajax({
        url: 'savePDF.php',
        type: 'post',
        data: {imageSrc: data}
    });
});

You can use any other HTML to PDF tool, not only TCPDF.
