TypeError: Unsupported operand types: float + string in TCPDF->Write() (line 6442 ... tcpdf.php).

[arx-e]

I was getting this error while using the library with Drupal module Views PDF 7.x-3.1 and TCPDF 6.6.2 (running php 8.0 or 8.1)
TypeError: Unsupported operand types: float + string in TCPDF->Write() (line 6442 of ... /tcpdf/tcpdf.php).

The issue has been solved by the following modification to line 6442 of tcpdf.php:
from this
$maxy = $this->y + $maxh - max($row_height, $h);
to this
$maxy = $this->y + (float)$maxh - max($row_height, $h);

Following this suggestion https://phpcod.com/fatal-error-uncaught-typeerror-unsupported-operand-types-string-float/

Does newer versions of TCPDF also have this issue ?
Any patch of pull-request to fix it is very welcome

as of version 6.9.4 this is still an issue when using strict types.

okay, can you provide a full TCPDF example ?
