Bitmap Fonts and Better
Thanks to the financial support of Expert Germany,
WeasyPrint has now a better support of
line-clamp and supports bitmap fonts 🎉.
You can now use your favorite OpenType bitmap (otb) fonts in your documents.
If you use rasterizer tools, like Poppler or Ghostscript, you’ll get pixel-perfect rendering ✨!

Thanks to the financial support of Blueshoe, you can generate PDF/A documents 🎉.
PDF/A is a version of PDF specialized for archiving and long-term conservation purposes.
Several conformance levels exist with different requirements. WeasyPrint supports:
Each level of conformance hasn’t the same requirements about how and what has to be store in the document itself and which PDF version is needed.

How to set PDF version?

How to set custom metadata?
For archiving purpose, you may need to have custom metadata in your documents.
To do that, you add them in your HTML file with the
When generating the PDF, use the
The generation of PDF/A document is experimental and the generated PDFs aren’t guarenteed to be valid. Don’t hesitate to open a new issue if you encounter problem with it 😉!.
What Are the Next Steps?
The next step is yours! Don’t hesitate to try this beta and report bugs you may find 🪲.
The one after is to fix the reported bugs and release a nice WeasyPrint version 56.
Thanks again to Expert Germany and Blueshoe for sponsoring these features. It has been a real pleasure to work with them!
Have fun with this beta 💜.
