It takes the current exception as a parameter of the constructor.

It provides 2 methods

• getMessage()
• getHtmlMessage();

Usage example:

try {
    use Spipu\Html2Pdf\Html2Pdf;
    use Spipu\Html2Pdf\Exception\Html2PdfException;
    use Spipu\Html2Pdf\Exception\ExceptionFormatter;

    $html2pdf = new Html2Pdf('P', 'A4', 'fr');
    $html2pdf->setDefaultFont('Arial');
    $html2pdf->writeHTML($htmlContent);
    $html2pdf->output();
} catch (Html2PdfException $e) {
    $html2pdf->clean();

    $formatter = new ExceptionFormatter($e);
    echo $formatter->getHtmlMessage();
}
