Originally released under LGPL. Graciously donated to PIL in
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.
0.0.1 alpha first public release, Dec. 26, 2002
Known to-do list with current version (of Python interface, not pyCMSdll):

(pyCMS) Applies an ICC transformation to a given image, mapping from
``inputProfile`` to ``outputProfile``.
If the input or output profiles specified are not valid filenames, a
:exc:`PyCMSError` will be raised. If ``inPlace`` is ``True`` and
``outputMode != im.mode``, a :exc:`PyCMSError` will be raised.
If an error occurs during application of the profiles,
a :exc:`PyCMSError` will be raised.
If ``outputMode`` is not a mode supported by the ``outputProfile`` (or by pyCMS),
a :exc:`PyCMSError` will be raised.
This function applies an ICC transformation to im from ``inputProfile``'s
color space to ``outputProfile``'s color space using the specified rendering
intent to decide how to handle out-of-gamut colors.
``outputMode`` can be used to specify that a color mode conversion is to
be done using these profiles, but the specified profiles must be able
to handle that mode. I.e., if converting im from RGB to CMYK using
profiles, the input profile must handle RGB data, and the output
profile must handle CMYK data.
:param im: An open :py:class:`~PIL.Image.Image` object (i.e. Image.new(...)
or Image.open(...), etc.)
:param inputProfile: String, as a valid filename path to the ICC input
profile you wish to use for this image, or a profile object
:param outputProfile: String, as a valid filename path to the ICC output
profile you wish to use for this image, or a profile object
:param renderingIntent: Integer (0-3) specifying the rendering intent you
wish to use for the transform
ImageCms.Intent.PERCEPTUAL = 0 (DEFAULT)
ImageCms.Intent.RELATIVE_COLORIMETRIC = 1
ImageCms.Intent.SATURATION = 2
ImageCms.Intent.ABSOLUTE_COLORIMETRIC = 3
see the pyCMS documentation for details on rendering intents and what
they do.
:param outputMode: A valid PIL mode for the output image (i.e. "RGB",
"CMYK", etc.). Note: if rendering the image "inPlace", outputMode
MUST be the same mode as the input, or omitted completely. If
omitted, the outputMode will be the same as the mode of the input
image (im.mode)
:param inPlace: Boolean. If ``True``, the original image is modified in-place,
and ``None`` is returned. If ``False`` (default), a new
:py:class:`~PIL.Image.Image` object is returned with the transform applied.
:param flags: Integer (0-...) specifying additional flags
:returns: Either None or a new :py:class:`~PIL.Image.Image` object, depending on
the value of ``inPlace``

(pyCMS) Opens an ICC profile file.
The PyCMSProfile object can be passed back into pyCMS for use in creating
transforms and such (as in ImageCms.buildTransformFromOpenProfiles()).
If ``profileFilename`` is not a valid filename for an ICC profile,
a :exc:`PyCMSError` will be raised.
:param profileFilename: String, as a valid filename path to the ICC profile
you wish to open, or a file-like object.
:returns: A CmsProfile class object.

(pyCMS) Builds an ICC transform mapping from the ``inputProfile`` to the
``outputProfile``. Use applyTransform to apply the transform to a given
image.
If the input or output profiles specified are not valid filenames, a
:exc:`PyCMSError` will be raised. If an error occurs during creation
of the transform, a :exc:`PyCMSError` will be raised.
If ``inMode`` or ``outMode`` are not a mode supported by the ``outputProfile``
(or by pyCMS), a :exc:`PyCMSError` will be raised.
This function builds and returns an ICC transform from the ``inputProfile``
to the ``outputProfile`` using the ``renderingIntent`` to determine what to do
with out-of-gamut colors. It will ONLY work for converting images that
are in ``inMode`` to images that are in ``outMode`` color format (PIL mode,
i.e. "RGB", "RGBA", "CMYK", etc.).
Building the transform is a fair part of the overhead in
ImageCms.profileToProfile(), so if you're planning on converting multiple
images using the same input/output settings, this can save you time.
Once you have a transform object, it can be used with
ImageCms.applyProfile() to convert images without the need to re-compute
the lookup table for the transform.
The reason pyCMS returns a class object rather than a handle directly
to the transform is that it needs to keep track of the PIL input/output
modes that the transform is meant for. These attributes are stored in
the ``inMode`` and ``outMode`` attributes of the object (which can be
manually overridden if you really want to, but I don't know of any
time that would be of use, or would even work).
:param inputProfile: String, as a valid filename path to the ICC input
profile you wish to use for this transform, or a profile object
:param outputProfile: String, as a valid filename path to the ICC output
profile you wish to use for this transform, or a profile object
:param inMode: String, as a valid PIL mode that the appropriate profile
also supports (i.e. "RGB", "RGBA", "CMYK", etc.)
:param outMode: String, as a valid PIL mode that the appropriate profile
also supports (i.e. "RGB", "RGBA", "CMYK", etc.)
:param renderingIntent: Integer (0-3) specifying the rendering intent you
wish to use for the transform
ImageCms.Intent.PERCEPTUAL = 0 (DEFAULT)
ImageCms.Intent.RELATIVE_COLORIMETRIC = 1
ImageCms.Intent.SATURATION = 2
ImageCms.Intent.ABSOLUTE_COLORIMETRIC = 3
see the pyCMS documentation for details on rendering intents and what
they do.

(pyCMS) Builds an ICC transform mapping from the ``inputProfile`` to the
``outputProfile``, but tries to simulate the result that would be
obtained on the ``proofProfile`` device.
If the input, output, or proof profiles specified are not valid
filenames, a :exc:`PyCMSError` will be raised.
If an error occurs during creation of the transform,
a :exc:`PyCMSError` will be raised.
If ``inMode`` or ``outMode`` are not a mode supported by the ``outputProfile``
(or by pyCMS), a :exc:`PyCMSError` will be raised.
This function builds and returns an ICC transform from the ``inputProfile``
to the ``outputProfile``, but tries to simulate the result that would be
obtained on the ``proofProfile`` device using ``renderingIntent`` and
``proofRenderingIntent`` to determine what to do with out-of-gamut
colors. This is known as "soft-proofing". It will ONLY work for
converting images that are in ``inMode`` to images that are in outMode
color format (PIL mode, i.e. "RGB", "RGBA", "CMYK", etc.).
Usage of the resulting transform object is exactly the same as with
ImageCms.buildTransform().
Proof profiling is generally used when using an output device to get a
good idea of what the final printed/displayed image would look like on
the ``proofProfile`` device when it's quicker and easier to use the
output device for judging color. Generally, this means that the
output device is a monitor, or a dye-sub printer (etc.), and the simulated
device is something more expensive, complicated, or time consuming
(making it difficult to make a real print for color judgement purposes).
Soft-proofing basically functions by adjusting the colors on the
output device to match the colors of the device being simulated. However,
when the simulated device has a much wider gamut than the output
device, you may obtain marginal results.
:param inputProfile: String, as a valid filename path to the ICC input

(pyCMS) Applies a transform to a given image.
If ``im.mode != transform.inMode``, a :exc:`PyCMSError` is raised.
If ``inPlace`` is ``True`` and ``transform.inMode != transform.outMode``, a
:exc:`PyCMSError` is raised.
If ``im.mode``, ``transform.inMode`` or ``transform.outMode`` is not
supported by pyCMSdll or the profiles you used for the transform, a
:exc:`PyCMSError` is raised.
If an error occurs while the transform is being applied,
a :exc:`PyCMSError` is raised.
This function applies a pre-calculated transform (from
ImageCms.buildTransform() or ImageCms.buildTransformFromOpenProfiles())
to an image. The transform can be used for multiple images, saving
considerable calculation time if doing the same conversion multiple times.
If you want to modify im in-place instead of receiving a new image as
the return value, set ``inPlace`` to ``True``. This can only be done if
``transform.inMode`` and ``transform.outMode`` are the same, because we can't
change the mode in-place (the buffer sizes for some modes are
different). The default behavior is to return a new :py:class:`~PIL.Image.Image`
object of the same dimensions in mode ``transform.outMode``.
:param im: An :py:class:`~PIL.Image.Image` object, and im.mode must be the same
as the ``inMode`` supported by the transform.
:param transform: A valid CmsTransform class object
:param inPlace: Bool. If ``True``, ``im`` is modified in place and ``None`` is
returned, if ``False``, a new :py:class:`~PIL.Image.Image` object with the
transform applied is returned (and ``im`` is not changed). The default is
``False``.
:returns: Either ``None``, or a new :py:class:`~PIL.Image.Image` object,
depending on the value of ``inPlace``. The profile will be returned in
the image's ``info['icc_profile']``.

Use this function to create common profiles on-the-fly instead of

(pyCMS) Gets the internal product name for the given profile.
If ``profile`` isn't a valid CmsProfile object or filename to a profile,
a :exc:`PyCMSError` is raised If an error occurs while trying
to obtain the name tag, a :exc:`PyCMSError` is raised.
Use this function to obtain the INTERNAL name of the profile (stored
in an ICC tag in the profile itself), usually the one used when the
profile was originally created. Sometimes this tag also contains
additional information supplied by the creator.
:param profile: EITHER a valid CmsProfile object, OR a string of the
filename of an ICC profile.

(pyCMS) Gets the default intent name for the given profile.
If ``profile`` isn't a valid CmsProfile object or filename to a profile, a
:exc:`PyCMSError` is raised.
If an error occurs while trying to obtain the default intent, a
:exc:`PyCMSError` is raised.
Use this function to determine the default (and usually best optimized)
rendering intent for this profile. Most profiles support multiple
rendering intents, but are intended mostly for one type of conversion.
If you wish to use a different intent than returned, use
ImageCms.isIntentSupported() to verify it will work first.
:param profile: EITHER a valid CmsProfile object, OR a string of the
filename of an ICC profile.
:returns: Integer 0-3 specifying the default rendering intent for this
profile.
ImageCms.Intent.PERCEPTUAL = 0 (DEFAULT)

(pyCMS) Checks if a given intent is supported.
Use this function to verify that you can use your desired
``intent`` with ``profile``, and that ``profile`` can be used for the
input/output/proof profile as you desire.
Some profiles are created specifically for one "direction", can cannot
be used for others. Some profiles can only be used for certain
rendering intents, so it's best to either verify this before trying
to create a transform with them (using this function), or catch the
potential :exc:`PyCMSError` that will occur if they don't
support the modes you select.
:param profile: EITHER a valid CmsProfile object, OR a string of the
filename of an ICC profile.
:param intent: Integer (0-3) specifying the rendering intent you wish to
use with this profile
ImageCms.Intent.PERCEPTUAL = 0 (DEFAULT)
ImageCms.Intent.RELATIVE_COLORIMETRIC = 1
ImageCms.Intent.SATURATION = 2
ImageCms.Intent.ABSOLUTE_COLORIMETRIC = 3
see the pyCMS documentation for details on rendering intents and what
they do.
:param direction: Integer specifying if the profile is to be used for
input, output, or proof
INPUT = 0 (or use ImageCms.Direction.INPUT)
OUTPUT = 1 (or use ImageCms.Direction.OUTPUT)
PROOF = 2 (or use ImageCms.Direction.PROOF)
:returns: 1 if the intent/direction are supported, -1 if they are not.
