PyPDF4

PyPDF4 is a pure-python PDF library capable of splitting, merging together, cropping, and transforming the pages of PDF files. It can also add custom data, viewing options, and passwords to PDF files. It can retrieve text and metadata from PDFs as well as merge entire files together.

What happened to PyPDF2? Nothing; it's still available at https://github.com/mstamy2/PyPDF2. For various reasons @claird will eventually explain, I've simply decided to mark a new "business model" with a slightly-renamed project name. While PyPDF4 will continue to be available at no charge, I have strong plans for better ongoing support to start in August 2018.

Homepage (available soon): http://claird.github.io/PyPDF4/.

Examples

Please see the samplecode/ folder.

Documentation

Documentation soon will be available, although probably not at https://pythonhosted.org/PyPDF4/.

FAQ

Please see http://claird.github.io/PyPDF4/FAQ.html (available in early August).

Tests

PyPDF4 includes a modest (but growing!) test suite built on the unittest framework. All tests are located in the tests/ folder and are distributed among dedicated modules. Tox makes running all tests over all versions of Python quick work:

python -m pip install tox
python -m tox

Individual tests are accessible as conventional Pytest sources;

pytest -v tests/test_pdf.py

is an example which assumes the pytest executable is activated.

Contributing

For an exhaustive overview of what rules you are expected to maintain, please visit Contributing in the project Wiki. A quick outline of these is:

  • Provide test cases for individual units of development of your own. Proper testing is highly encouraged: Code without tests is broken by design - Jacob Kaplan-Moss, Django's original development team member.
  • Follow the PEP 8 style conventions, such as:
    • lower_case_with_underscores nomenclature (e.g., file_name rather than fileName, and write_file() rather than writeFile()).
    • Line lengths of 79 characters or less.
    • Correct spacing between global-scoped classes and functions (two newlines in between etc.) and within internal code blocks.
  • Target your code for Python 3 but maintain retrocompatibility with Python 2 (do we retain Py2? Still under active consideration).
  • Provide docstring documentation for public classes and functions.
  • Utilize # TO-DO or TO-DO markings within docstrings for indicating a feature that is yet to be implemented or discussed. Some IDEs feature TO-DOs detection consoles.
