If the ``pillowcases`` module is imported afterwards, the ``PIL.Image`` module's ``PIL.Image.Image`` class is redefined to refer to the ``pillowcases.Image`` class (which is itself derived from the ``PIL.Image.Image`` class):\n\n.. code-block:: python\n\n    \u003e\u003e\u003e import PIL.Image\n    \u003e\u003e\u003e import pillowcases\n    \u003e\u003e\u003e i = PIL.Image.frombytes('RGBA', (2, 2), bytes([0]*16))\n    \u003e\u003e\u003e isinstance(i, pillowcases.Image)\n    True\n\n.. |set| replace:: ``set``\n.. _set: https://docs.python.org/3/library/stdtypes.html#set\n\n.. |dict| replace:: ``dict``\n.. _dict: https://docs.python.org/3/library/stdtypes.html#dict\n\nBecause instances of ``pillowcases.Image`` are `hashable \u003chttps://docs.python.org/3/glossary.html#term-hashable\u003e`__, they can be added as elements to |set|_ objects and can be used as keys in |dict|_ objects:\n\n.. code-block:: python\n\n    \u003e\u003e\u003e j = PIL.Image.frombytes('RGBA', (2, 2), bytes([0]*16))\n    \u003e\u003e\u003e k = PIL.Image.frombytes('RGBA', (2, 2), bytes([255]*16))\n    \u003e\u003e\u003e len({i, j, k})\n    2\n    \u003e\u003e\u003e d = {j: 1, k: 2}\n    \u003e\u003e\u003e d[k]\n    2\n\nCompare the above to the default behavior of the ``PIL.Image.Image`` class, demonstrated below:\n\n.. code-block:: python\n\n    \u003e\u003e\u003e from importlib import reload\n    \u003e\u003e\u003e PIL.Image = reload(PIL.Image)\n    \u003e\u003e\u003e i = PIL.Image.frombytes('RGBA', (2, 2), bytes([0]*16))\n    \u003e\u003e\u003e j = PIL.Image.frombytes('RGBA', (2, 2), bytes([0]*16))\n    \u003e\u003e\u003e j = PIL.Image.frombytes('RGBA', (2, 2), bytes([255]*16))\n    \u003e\u003e\u003e len({i, j, k})\n    Traceback (most recent call last):\n        ...\n    TypeError: unhashable type: 'Image'\n\nDevelopment\n-----------\nAll installation and development dependencies are fully specified in ``pyproject.toml``. The ``project.optional-dependencies`` object is used to `specify optional requirements \u003chttps://peps.python.org/pep-0621\u003e`__ for various development tasks. This makes it possible to specify additional options (such as ``docs``, ``lint``, and so on) when performing installation using `pip \u003chttps://pypi.org/project/pip\u003e`__:\n\n.. code-block:: bash\n\n    python -m pip install .[docs,lint]\n\nDocumentation\n^^^^^^^^^^^^^\nThe documentation can be generated automatically from the source files using `Sphinx \u003chttps://www.sphinx-doc.org\u003e`__:\n\n.. code-block:: bash\n\n    python -m pip install .[docs]\n    cd docs\n    sphinx-apidoc -f -E --templatedir=_templates -o _source .. \u0026\u0026 make html\n\nTesting and Conventions\n^^^^^^^^^^^^^^^^^^^^^^^\nAll unit tests are executed and their coverage is measured when using `pytest \u003chttps://docs.pytest.org\u003e`__ (see the ``pyproject.toml`` file for configuration details):\n\n.. code-block:: bash\n\n    python -m pip install .[test]\n    python -m pytest\n\nAlternatively, all unit tests are included in the module itself and can be executed using `doctest \u003chttps://docs.python.org/3/library/doctest.html\u003e`__:\n\n.. code-block:: bash\n\n    python src/pillowcases/pillowcases.py -v\n\nStyle conventions are enforced using `Pylint \u003chttps://pylint.readthedocs.io\u003e`__:\n\n.. code-block:: bash\n\n    python -m pip install .[lint]\n    python -m pylint src/pillowcases\n\nContributions\n^^^^^^^^^^^^^\nIn order to contribute to the source code, open an issue or submit a pull request on the `GitHub page \u003chttps://github.com/lapets/pillowcases\u003e`__ for this library.\n\nVersioning\n^^^^^^^^^^\nThe version number format for this library and the changes to the library associated with version number increments conform with `Semantic Versioning 2.0.0 \u003chttps://semver.org/#semantic-versioning-200\u003e`__.\n\nPublishing\n^^^^^^^^^^\nThis library can be published as a `package on PyPI \u003chttps://pypi.org/project/pillowcases\u003e`__ by a package maintainer. First, install the dependencies required for packaging and publishing:\n\n.. code-block:: bash\n\n    python -m pip install .[publish]\n\nEnsure that the correct version number appears in ``pyproject.toml``, and that any links in this README document to the Read the Docs documentation of this package (or its dependencies) have appropriate version numbers. Also ensure that the Read the Docs project for this library has an `automation rule \u003chttps://docs.readthedocs.io/en/stable/automation-rules.html\u003e`__ that activates and sets as the default all tagged versions. Create and push a tag for this version (replacing ``?.?.?`` with the version number):\n\n.. code-block:: bash\n\n    git tag ?.?.?\n    git push origin ?.?.?\n\nRemove any old build/distribution files. Then, package the source into a distribution archive:\n\n.. code-block:: bash\n\n    rm -rf build dist src/*.egg-info\n    python -m build --sdist --wheel .\n\nFinally, upload the package distribution archive to `PyPI \u003chttps://pypi.org\u003e`__:\n\n.. code-block:: bash\n\n    python -m twine upload dist/*\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flapets%2Fpillowcases","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flapets%2Fpillowcases","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flapets%2Fpillowcases/lists"}
