I encountered an OverflowError when trying to generate a PDF document from an HTML file using WeasyPrint version 62.3. The error occurs on the following line of code: weasyprint/draw.py#L1430.

Reproduction Steps

To reproduce the issue, you can use the minimal HTML and Python code snippets below.

Minimal HTML file:

<!DOCTYPE html>
<html>
<head>
    <style type="text/css">
        table {
            text-align: justify;
        }
    </style>
</head>
<body>
<table>
    <tr>
        <td>
            X Y ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
        </td>
    </tr>
</table>
</body>
</html>

Minimal Python code:

import argparse

import weasyprint


if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('html')
    parser.add_argument('pdf')
    args = parser.parse_args()

    with open(args.html, 'r') as html:
        with open(args.pdf, 'wb') as pdf:
            weasyprint.HTML(string=html.read()).write_pdf(pdf)

Expected Behavior

A PDF document should be generated without any errors.

Actual Behavior

An OverflowError is raised when attempting to generate the PDF.

Environment

  • WeasyPrint version: 62.3
  • Python version: 3.12
  • Operating System: Ubuntu
