PyMuPDF-1.23.0 released

[julian-smith-artifex-com]

PyMuPDF-1.23.0 has been released.

Wheels for Windows, Linux and MacOS, and the sdist, are available on pypi.org and can be installed in the usual way, for example:

python -m pip install --upgrade pymupdf

Changes in version 1.23.0 (2023-08-22)

• Add method find_tables() to the Page object.

  This allows locating tables on any supported document page, and
  extracting table content by cell.

• New "rebased" implementation of PyMuPDF.

  The rebased implementation is available as Python module
  fitz_new. It can be used as a drop-in replacement with import fitz_new as fitz.

• Python-independent MuPDF libraries are now in a second wheel called
  PyMuPDFb that will be automatically installed by pip.

  This is to save space on pypi.org - a full release only needs one
  PyMuPDFb wheel for each OS.

• Bug fixes:

  • Fixed fritz.utils.scrub AttributeError Annot object has no attribute fileUpd inside  #2542
  • Fixed get_texttrace returned a incorrect character bbox #2533
  • Fixed Validation when setting a grouped RadioButton throws a RuntimeError: path to 'V' has indirects #2537

• Other changes:

  • Dropped support for Python-3.7.

  • Fix for wrong page / annot /Contents cleaning.

    We need to set pdf_filter_options::no_update to zero.

  • Added new function get_tessdata().

  • Cope with problem /Annot arrays.

    When copying page annotations in method Document.insert_pdf we
    previously did not check the validity of members of the /Annots
    array. For faulty members (like null or non-dictionary items) this
    could cause unnecessary exceptions. This fix implements more checks
    and skips such array items.

  • Additional annotation type checks.

    We did not previously check for annotation type when getting /
    setting annotation border properties. This is now checked in
    accordance with MuPDF.

  • Increase fault tolerance.

    Avoid exceptions in method insert_pdf() when source pages contains
    invalid items in the /Annots array.

  • Return empty border dict for applicable annots.

    We previously were returning a non-empty border dictionary even for
    non-applicable annotation types. We now return the empty dictionary
    {} in these cases. This requires some corresponding changes in the
    annotation .update() method, namely for dashes and border width.

  • Restrict set_rect to applicable annot types.

    We were insufficiently excluding non-applicable annotation types
    from set_rect() method. We now let MuPDF catch unsupported
    annotations and return False in these cases.

  • Wrong fontsize computation in page.get_texttrace().

    When computing the font size we were using the final text
    transformation matrix, where we should have taken span->trm
    instead. This is corrected here.

  • Updates to cope with changes to latest MuPDF.

    pdf_lookup_anchor() has been removed.

  • Update fill_textbox to better respect rect.width

    The function norm_words in fill_textbox had a bug in its last
    loop, appending n+1 characters when actually measuring width of n
    characters. It led to a bug in fill_texbox when you tried to write
    a single word mostly composed of "wide" letters (M,m, W, w...),
    causing the written text to exceed the given rect.

    The fix was just to replace n+1 by n.

  • Add script_focus and script_blur options to widget.
