+JPEG quality settings equivalent to the Photoshop settings.
+Can be used when saving JPEG files.
+
+The following presets are available by default:
+``web_low``, ``web_medium``, ``web_high``, ``web_very_high``, ``web_maximum``,
+``low``, ``medium``, ``high``, ``maximum``.
+More presets can be added to the :py:data:`presets` dict if needed.
+
+To apply the preset, specify::
+
+  quality="preset_name"
+
+To apply only the quantization table::
+
+  qtables="preset_name"
+
+To apply only the subsampling setting::
+
+  subsampling="preset_name"
+
+Example::
+
+  im.save("image_name.jpg", quality="web_high")
+
+Subsampling
+-----------
+
+Subsampling is the practice of encoding images by implementing less resolution
+for chroma information than for luma information.
+(ref.: https://en.wikipedia.org/wiki/Chroma_subsampling)
+
+Possible subsampling values are 0, 1 and 2 that correspond to 4:4:4, 4:2:2 and
+4:2:0.
+
+You can get the subsampling of a JPEG with the
+:func:`.JpegImagePlugin.get_sampling` function.
+
+In JPEG compressed data a JPEG marker is used instead of an EXIF tag.
+(ref.: https://exiv2.org/tags.html)
+
+
+Quantization tables
+-------------------
+
+They are values use by the DCT (Discrete cosine transform) to remove
+*unnecessary* information from the image (the lossy part of the compression).
+(ref.: https://en.wikipedia.org/wiki/Quantization_matrix#Quantization_matrices,
+https://en.wikipedia.org/wiki/JPEG#Quantization)
+
+You can get the quantization tables of a JPEG with::
+
+  im.quantization
+
+This will return a dict with a number of lists. You can pass this dict
+directly as the qtables argument when saving a JPEG.
+
+The quantization table format in presets is a list with sublists. These formats
+are interchangeable.

+# TIFF file handling
+#
+# TIFF is a flexible, if somewhat aged, image file format originally
+# defined by Aldus.  Although TIFF supports a wide variety of pixel
+# layouts and compression methods, the name doesn't really stand for
+# "thousands of incompatible file formats," it just feels that way.
+#
+# To read TIFF data from a stream, the stream must be seekable.  For
+# progressive decoding, make sure to use TIFF files where the tag
+# directory is placed first in the file.
+#
+# History:
+# 1995-09-01 fl   Created
+# 1996-05-04 fl   Handle JPEGTABLES tag
+# 1996-05-18 fl   Fixed COLORMAP support
+# 1997-01-05 fl   Fixed PREDICTOR support
+# 1997-08-27 fl   Added support for rational tags (from Perry Stoll)
+# 1998-01-10 fl   Fixed seek/tell (from Jan Blom)
+# 1998-07-15 fl   Use private names for internal variables
+# 1999-06-13 fl   Rewritten for PIL 1.0 (1.0)
+# 2000-10-11 fl   Additional fixes for Python 2.0 (1.1)
+# 2001-04-17 fl   Fixed rewind support (seek to frame 0) (1.2)
+# 2001-05-12 fl   Added write support for more tags (from Greg Couch) (1.3)
+# 2001-12-18 fl   Added workaround for broken Matrox library
+# 2002-01-18 fl   Don't mess up if photometric tag is missing (D. Alan Stewart)
+# 2003-05-19 fl   Check FILLORDER tag
+# 2003-09-26 fl   Added RGBa support
+# 2004-02-24 fl   Added DPI support; fixed rational write support
+# 2005-02-07 fl   Added workaround for broken Corel Draw 10 files
+# 2006-01-09 fl   Added support for float/double tags (from Russell Nelson)

+dill: serialize all of Python
+-----------------------------
+
+About Dill
+==========
+
+``dill`` extends Python's ``pickle`` module for serializing and de-serializing
+Python objects to the majority of the built-in Python types. Serialization
+is the process of converting an object to a byte stream, and the inverse
+of which is converting a byte stream back to a Python object hierarchy.
+
+``dill`` provides the user the same interface as the ``pickle`` module, and
+also includes some additional features. In addition to pickling Python
+objects, ``dill`` provides the ability to save the state of an interpreter
+session in a single command.  Hence, it would be feasible to save an
+interpreter session, close the interpreter, ship the pickled file to
+another computer, open a new interpreter, unpickle the session and
+thus continue from the 'saved' state of the original interpreter
+session.
+
+``dill`` can be used to store Python objects to a file, but the primary
+usage is to send Python objects across the network as a byte stream.
+``dill`` is quite flexible, and allows arbitrary user defined classes
+and functions to be serialized.  Thus ``dill`` is not intended to be
+secure against erroneously or maliciously constructed data. It is
+left to the user to decide whether the data they unpickle is from
+a trustworthy source.
+
+``dill`` is part of ``pathos``, a Python framework for heterogeneous computing.
+``dill`` is in active development, so any user feedback, bug reports, comments,
+or suggestions are highly appreciated.  A list of issues is located at
+https://github.com/uqfoundation/dill/issues, with a legacy list maintained at
+https://uqfoundation.github.io/project/pathos/query.
+
+
+Major Features
+==============
+
+``dill`` can pickle the following standard types:
+
+    - none, type, bool, int, float, complex, bytes, str,
+    - tuple, list, dict, file, buffer, builtin,
+    - Python classes, namedtuples, dataclasses, metaclasses,
+    - instances of classes,
+    - set, frozenset, array, functions, exceptions
+
+``dill`` can also pickle more 'exotic' standard types:
+
+    - functions with yields, nested functions, lambdas,
+    - cell, method, unboundmethod, module, code, methodwrapper,
+    - methoddescriptor, getsetdescriptor, memberdescriptor, wrapperdescriptor,
+    - dictproxy, slice, notimplemented, ellipsis, quit
+
+``dill`` cannot yet pickle these standard types:
+
+    - frame, generator, traceback
+
+``dill`` also provides the capability to:
+
+    - save and load Python interpreter sessions
+    - save and extract the source code from functions and classes
+    - interactively diagnose pickling errors
+
+
+Current Release
+===============
+
+The latest released version of ``dill`` is available from:
+
+    https://pypi.org/project/dill
+
+``dill`` is distributed under a 3-clause BSD license.
+
+
+Development Version
+===================
+
+You can get the latest development version with all the shiny new features at:
+
+    https://github.com/uqfoundation
+
+If you have a new contribution, please submit a pull request.
+
+
+Installation
+============
+
+``dill`` can be installed with ``pip``::
+
+    $ pip install dill
+
+To optionally include the ``objgraph`` diagnostic tool in the install::
+
+    $ pip install dill[graph]
+
+To optionally include the ``gprof2dot`` diagnostic tool in the install::
+
+    $ pip install dill[profile]
+
+For windows users, to optionally install session history tools::
+
+    $ pip install dill[readline]
+
+
+Requirements
+============
+
+``dill`` requires:
+
+    - ``python`` (or ``pypy``), **>=3.8**
+    - ``setuptools``, **>=42**
+
+Optional requirements:
+
+    - ``objgraph``, **>=1.7.2**
+    - ``gprof2dot``, **>=2022.7.29**
+    - ``pyreadline``, **>=1.7.1** (on windows)
+
+
+Basic Usage
+===========
+
+``dill`` is a drop-in replacement for ``pickle``. Existing code can be
+updated to allow complete pickling using::
+
+    >>> import dill as pickle
+
+or::
+
+    >>> from dill import dumps, loads
+
+``dumps`` converts the object to a unique byte string, and ``loads`` performs
+the inverse operation::
+
+    >>> squared = lambda x: x**2
+    >>> loads(dumps(squared))(3)
+    9
+
+There are a number of options to control serialization which are provided
+as keyword arguments to several ``dill`` functions:
+
+* with *protocol*, the pickle protocol level can be set. This uses the
+  same value as the ``pickle`` module, *DEFAULT_PROTOCOL*.
+* with *byref=True*, ``dill`` to behave a lot more like pickle with
+  certain objects (like modules) pickled by reference as opposed to
+  attempting to pickle the object itself.
+* with *recurse=True*, objects referred to in the global dictionary are
+  recursively traced and pickled, instead of the default behavior of
+  attempting to store the entire global dictionary.
+* with *fmode*, the contents of the file can be pickled along with the file
+  handle, which is useful if the object is being sent over the wire to a
+  remote system which does not have the original file on disk. Options are
+  *HANDLE_FMODE* for just the handle, *CONTENTS_FMODE* for the file content
+  and *FILE_FMODE* for content and handle.
+* with *ignore=False*, objects reconstructed with types defined in the
+  top-level script environment use the existing type in the environment
+  rather than a possibly different reconstructed type.
+
+The default serialization can also be set globally in *dill.settings*.
+Thus, we can modify how ``dill`` handles references to the global dictionary
+locally or globally::
+
+    >>> import dill.settings
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    False
+    >>> dill.settings['recurse'] = True
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    True
+
+``dill`` also includes source code inspection, as an alternate to pickling::
+
+    >>> import dill.source
+    >>> print(dill.source.getsource(squared))
+    squared = lambda x:x**2
+
+To aid in debugging pickling issues, use *dill.detect* which provides
+tools like pickle tracing::
+
+    >>> import dill.detect
+    >>> with dill.detect.trace():
+    >>>     dumps(squared)
+    ┬ F1: <function <lambda> at 0x7fe074f8c280>
+    ├┬ F2: <function _create_function at 0x7fe074c49c10>
+    │└ # F2 [34 B]
+    ├┬ Co: <code object <lambda> at 0x7fe07501eb30, file "<stdin>", line 1>
+    │├┬ F2: <function _create_code at 0x7fe074c49ca0>
+    ││└ # F2 [19 B]
+    │└ # Co [87 B]
+    ├┬ D1: <dict object at 0x7fe0750d4680>
+    │└ # D1 [22 B]
+    ├┬ D2: <dict object at 0x7fe074c5a1c0>
+    │└ # D2 [2 B]
+    ├┬ D2: <dict object at 0x7fe074f903c0>
+    │├┬ D2: <dict object at 0x7fe074f8ebc0>
+    ││└ # D2 [2 B]
+    │└ # D2 [23 B]
+    └ # F1 [180 B]
+
+With trace, we see how ``dill`` stored the lambda (``F1``) by first storing
+``_create_function``, the underlying code object (``Co``) and ``_create_code``
+(which is used to handle code objects), then we handle the reference to
+the global dict (``D2``) plus other dictionaries (``D1`` and ``D2``) that
+save the lambda object's state. A ``#`` marks when the object is actually stored.
+
+
+More Information
+================
+
+Probably the best way to get started is to look at the documentation at
+http://dill.rtfd.io. Also see ``dill.tests`` for a set of scripts that
+demonstrate how ``dill`` can serialize different Python objects. You can
+run the test suite with ``python -m dill.tests``. The contents of any
+pickle file can be examined with ``undill``.  As ``dill`` conforms to
+the ``pickle`` interface, the examples and documentation found at
+http://docs.python.org/library/pickle.html also apply to ``dill``
+if one will ``import dill as pickle``. The source code is also generally
+well documented, so further questions may be resolved by inspecting the
+code itself. Please feel free to submit a ticket on github, or ask a
+question on stackoverflow (**@Mike McKerns**).
+If you would like to share how you use ``dill`` in your work, please send
+an email (to **mmckerns at uqfoundation dot org**).
