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