This version is experimental, don't use it in production. If you find bugs, please report them!

Command-line API

  • The --optimize-size option and its short equivalent -O have been deprecated. To activate or deactivate different size optimizations, you can now use:

    • --uncompressed-pdf,
    • --optimize-images,
    • --full-fonts,
    • --hinting,
    • --dpi <resolution>, and
    • --jpeg-quality <quality>.
  • A new --cache-folder <folder> option has been added to store temporary data in the given folder on the disk instead of keeping them in memory.

Python API

  • Global rendering options are now given in **options instead of dedicated parameters, with slightly different names. It means that the signature of the HTML.render(), HTML.write_pdf() and Document.write_pdf() has changed. Here are the steps to port your Python code to v59.0:

    1. Use named parameters for these functions, not positioned parameters.

    2. Rename some the parameters:

      • image_cache becomes cache (see below),
      • identifier becomes pdf_identifier,
      • variant becomes pdf_variant,
      • version becomes pdf_version,
      • forms becomes pdf_forms,
  • The optimize_size parameter of HTML.render(), HTML.write_pdf() and Document() has been removed and will be ignored. You can now use the uncompressed_pdf, full_fonts, hinting, dpi and jpeg_quality parameters that are included in **options.

  • The cache parameter can be included in **options to replace image_cache. If it is a dictionary, this dictionary will be used to store temporary data in memory, and can be even shared between multiple documents. If it’s a folder Path or string, WeasyPrint stores temporary data in the given temporary folder on disk instead of keeping them in memory.
