+    PIL read-only image support for Microsoft Windows .ico files.
+
+    By default the largest resolution image in the file will be loaded. This
+    can be changed by altering the 'size' attribute before calling 'load'.
+
+    The info dictionary has a key 'sizes' that is a list of the sizes available
+    in the icon file.
+

+    March 2009, for distribution under the standard PIL license
+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and
+    pyCMSdll, taking care of some of the more complex handling of the direct
+    pyCMSdll functions, as well as error-checking and making sure that all
+    relevant data is kept together.
+
+    While it is possible to call pyCMSdll functions directly, it's not highly
+    recommended.
+
+    Version History:
+
+        1.0.0 pil       Oct 2013 Port to LCMS 2.
+
+        0.1.0 pil mod   March 10, 2009
+
+                        Renamed display profile to proof profile. The proof
+                        profile is the profile of the device that is being
+                        simulated, not the profile of the device which is
+                        actually used to display/print the final simulation
+                        (that'd be the output profile) - also see LCMSAPI.txt
+                        input colorspace -> using 'renderingIntent' -> proof
+                        colorspace -> using 'proofRenderingIntent' -> output
+                        colorspace
+
+                        Added LCMS FLAGS support.
+                        Added FLAGS["SOFTPROOFING"] as default flag for
+                        buildProofTransform (otherwise the proof profile/intent
+                        would be ignored).
+
+        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
+
+        0.0.2 alpha     Jan 6, 2002
+
+                        Added try/except statements around type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.

+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.
