Generate playcard.pdf with Weasyprint¶
We are using Weasyprint version 52.5 on the Soupboat. The latest version is 54.1 (https://github.com/Kozea/WeasyPrint/releases), but from version 53 on you need to have libpango version 1.44 installed, and on the current version of Raspian OS (the operating system of the Soupboat) we can only have libpango version 1.42. So we will stay with Weasyprint v52.
$ sudo pip3 install weasyprint==52.5
You can use Weasyprint as a Python library or from the command line.
