pypdf - Version 4.0.0, 2024-01-19

What's new

pypdf==4.0.0 is a big milestone forward:

• We finally have a layout-mode text extraction. This enables users who want to detect / extract tables with heuristics to give it a try.
• We deprecated a lot of the old PyPDF2 API that was either not following PEP8 naming styles or was not using a property. Users comming from PyPDF2 might want to switch first to pypdf<4.0.0 to get helpful error messages that show the new API in their speicific cases.

A big 'Thank you!' the the whole pypdf community for your work. Thanks to you, pypdf is better than ever.

Kudos to @shartzog who added the layout-mode with his first contribution!

pypdf - 3.4.0

What's Changed

Version 3.4.0, 2023-02-05

NOTICE: pypdf changed the way it represents numbers parsed from PDF files. pypdf<3.4.0 represented numbers as Decimal, pypdf>=3.4.0 represents them as floats. Several other PDF libraries to this, as well as many PDF viewers. We hope to fix issues with too high precision like this and get a speed boost. In case your PDF documents rely on more than 18 decimals of precision you should check if it still works as expected. To clarify: This does not affect the text shown in PDF documents, even if the text are numbers. It affects numbers used by the PDF document, e.g. when graphics are drawn on the PDF or very exact positions are used. Typically, 5 decimals should be enough.

What's Changed

The highlight of the 2.1.0 release is the most massive improvement to the text extraction capabilities of PyPDF2 since 2016 🥳🎊 A very big thank you goes to pubpub-zz who took a lot of time and knowledge about the PDF format to finally get those improvements into PyPDF2. Thank you 🤗💚

In case the new function causes any issues, you can use _extract_text_old for the old functionality. Please also open a bug ticket in that case.

There were several people who have attempted to bring similar improvements to PyPDF2. All of those were valuable. The main reason why they didn't get merged is the big amount of open PRs / issues. pubpub-zz was the most comprehensive PR which also incorporated the latest changes of PyPDF2 2.0.0.

Thank you to VictorCarlquist for #858 and asabramo for #464 🤗

- Python
Published by MartinThoma over 3 years ago

pypdf - Version 2.0.0, 2022-06-01

What's Changed

The 2.0.0 release of PyPDF2 includes three core changes:

1. Dropping support for Python 3.5 and older.
2. Introducing type annotations.
3. Interface changes, mostly to have PEP8-compliant names

We introduced a deprecation process that hopefully helps users to avoid unexpected breaking changes.

Breaking Changes (DEP)

• PyPDF2 2.0 requires Python 3.6+. Python 2.7 and 3.5 support were dropped.
• PdfFileReader: The "warndest" parameter was removed
• PdfFileReader and PdfFileMerger no longer have the overwriteWarnings parameter. The new behavior is overwriteWarnings=False.
• merger: OutlinesObject was removed without replacement.
• merger.py ➔ _merger.py: You must import PdfFileMerger from PyPDF2 directly.
• utils:
  • ConvertFunctionsToVirtualList was removed
  • formatWarning was removed
  • isInt(obj): Use instance(obj, int) instead
  • u_(s): Use s directly
  • chr_(c): Use chr(c) instead
  • barray(b): Use bytearray(b) instead
  • isBytes(b): Use instance(b, type(bytes())) instead
  • xrange_fn: Use range instead
  • string_type: Use str instead
  • isString(s): Use instance(s, str) instead
  • _basestring: Use str instead
  • All Exceptions are now in PyPDF2.errors:
  • PageSizeNotDefinedError
  • PdfReadError
  • PdfReadWarning
  • PyPdfError
• PyPDF2.pdf (the pdf module) no longer exists. The contents were moved with the library. You should most likely import directly from PyPDF2 instead. The RectangleObject is in PyPDF2.generic.
• The Resources, Scripts, and Tests will no longer be part of the distribution files on PyPI. This should have little to no impact on most people. The Tests are renamed to tests, the Resources are renamed to resources. Both are still in the git repository. The Scripts are now in https://github.com/py-pdf/cpdf. Sample_Code was moved to the docs.

For a full list of deprecated functions, please see the changelog of version 1.28.0.

Version 1.28.0, 2022-05-22

This release adds a lot of deprecation warnings in preparation of the PyPDF2 2.0.0 release. The changes are mostly using snake_case function-, method-, and variable-names as well as using properties instead of getter-methods.

Maintenance (MAINT): - Remove IronPython Fallback for zlib (#868)

  • PdfFileReader ➔ PdfReader
  • PdfFileWriter ➔ PdfWriter
  • PdfFileMerger ➔ PdfMerger
• Use PEP8 conventions for function names and parameters
• If a property and a getter-method are both present, use the property

Details

In many places: - getObject ➔ getobject - writeToStream ➔ writetostream - readFromStream ➔ readfrom_stream

PyPDF2.generic - readObject ➔ readobject - convertToInt ➔ converttoint - DocumentInformation.getText ➔ DocumentInformation.get_text : This method should typically not be used; please let me know if you need it.
