ArgyllCMS documentation index (V2.0.1)
Date: 9th July 2018
Author: Graeme Gill
Introduction
ArgyllCMS is an ICC compatible color management system, available as
Open Source. It supports accurate ICC profile creation for scanners,
cameras and film recorders, and calibration and profiling of
displays and RGB, CMY & CMYK printers. Device Link can be
created with a wide variety of advanced options, including
specialized Video calibration standards and 3dLuts. Spectral
sample data is supported, allowing a selection of illuminants
observer types, and paper fluorescent whitener additive
compensation. Profiles can also incorporate source specific gamut
mappings for perceptual and saturation intents. Gamut mapping and
profile linking uses the CIECAM02 appearance model, a unique gamut
mapping algorithm, and a wide selection of rendering intents. It
also includes code for the fastest portable 8 bit raster color
conversion engine available anywhere, as well as support for fast,
fully accurate 16 bit conversion. Device color gamuts can also be
viewed and compared with a modern Web browser using X3DOM .
Comprehensive documentation is provided for each major tool, and a
general guide to using the tools for typical color management tasks
is also available. A mailing list provides support for more advanced
usage.
This is Version 2.0.1, a bug fix update to the last major release
V2.0.0. The first public release of icclib was in November 1998,
and of ArgyllCMS was in October 2000. Code development commenced
in 1995. See Changes Summary
for an overview of changes since the last release. Changes between
revisions is detailed in the log.txt file that accompanies
the source code.
The latest source code is available from here.
Please
note that instruments are being driven by ArgyllCMS drivers,
and that any problems or queries regarding instrument
operation should
first be directed to the Argyll's author(s) or the Argyll
mailing list, and not to any other party.
A great introduction for non technical people is Steve Upton's The
Color of Toast.
I present here a more technical but concise
discussion of what color management is, and why we need it,
together with a brief overview of the ICC profile format.

See Operation of particular
instruments for more instrument specific detail.
Other instruments can be supported indirectly, since patch result
files created by other packages can be imported into Argyll.
Please note the installation instructions
for each platform - they contain important information for getting
your instruments working.
If you've decided to buy a color instrument because Argyll
supports it, please let the dealer and manufacturer know that "You bought it because ArgyllCMS
supports it" - thanks.
Please note that instruments are
being driven by ArgyllCMS drivers, and that any problems or
queries regarding instrument
operation should be
directed to the Argyll's author(s) or the Argyll mailing list,
and not to any other
party.
There is a list of contributed ccss (Colorimeter Correction
Spectral Sample) files for some displays.
There is a list of contributed ccmx (Colorimeter Correction
Matrix) files for some display/colorimeter combinations.

What sort of project is this ? (re:
contributions)
This is essentially my private project, that I've made available
under GNU licensing conditions. Because I license my code under
other licenses as well, there is a limit to what I will accept in
the way of code contributions back into this project. For me to
accept contributions into the distribution, it either has to a
non-core (side) project, or has to be offered to me with copyright
conditions that are compatible with my other uses (i.e.. a "BSD" or
"MIT" like permissive free software license, or assigning or
licensing the copyright to me), or has to be so trivial (say a one
line bug fix), that it can't be the subject of copyright.
Of course there is nothing to stop someone setting up a real free
software, community project based on the GNU licensed code made
available here, that would be able to take GNU licensed
contributions from everyone and would essentially be a "fork" of
this code base.

source if you want to.
Note that you don't need to
do this if you are using one of the binary installations.

software on various platforms.
Graphic
User Interfaces
ArgyllCMS does not directly support a graphic user interface, but
several people have written GUI
based front ends for it. A popular front
end
that
supports
display
calibration
and profiling is DisplayCAL by
Florian Höch. For print profiling, you might like to take a look at
The
Little Argyll GUI by Russell Cottrell, and for cameras or
scanners, CoCa by Andrew
Stawowczyk Long. Another GUI worth looking at is Coloris, by Rémi and Lionel
Wetteren.
Others can be found with a suitable search.
Main
Tools and the command line
These are all command line ("DOS" shell) tools, and each tool
require appropriate options to be set, followed by filename
arguments. Sometimes the filenames will have to include the usual
extensions, sometimes they are implicit. To get a brief listing of
the possible arguments and usage
of any of the tools, run it with just an "-?" argument, i.e. targen
-? (or some other unrecognized flag, if the "?" character is
treated specially in your shell, i.e. try "--" on OS X zsh).
Note that in general the arguments consist of possible flags or
options followed by file path+name arguments. All arguments need to
be separated by whitespace. (If you need to specify a string
with embedded white space, double quote the string). A flag consists
of a dash attached to a single letter, the letter identifying the
flag, and is usually case sensitive. An option is a flag that has an
associated parameter or parameters. The parameter can be separated
from the flag by white space, or may come directly after the flag.
So if a tool has a usage that looks like this:
tool -?
usage: tool [options] infile outfile
-v
Verbose mode
-d
n
Choose a depth 0-4
-r
Use a random depth
-f
[nn]
Use full range. nn optional range 0 - 100.
-M
Manual
infile
Input file
outfile
Output file
then there are 5 flags/options, and two filename arguments.
Notice that square braces [] denote optional items. The first
flag/option is a flag. The second is an option that has a numerical
argument in the range 0 to 4. The third is a flag. the fourth is an
option with an optional argument. The fourth is a flag. The
flags and options can generally be in any order, but must be before
the file name arguments. (For a few special tools you actually
specify a sequence of flags and files where the flags apply just to
the following file.) So example invocations may look like:
tool -v testin testout
tool -d3 -M testin1 testout2
tool -f infile outfile
tool -f 45 infile outfile
tool -d 3 -f67 infile outfile
In order to make use of the tools, it is necessary to keep track
of where various files are, and what they are called. There are
many possible ways of doing this. One way is to put each source
profile and all its associated files (test charts, spectrometer
values etc.) in one set of directories for each source profile
type. Similarly the device profiles could be stored in a hierarchy
of directories ordered by device type, media, resolution, device
mode etc. Naturally you will want to set your $PATH so that you
can run the tools from whichever directory you are in, as well as
specify any necessary directory paths for file arguments so that
the tools are able to open them.
Note that there are two ways the Argyll tools deal with filename
extensions. In one you supply the extension (ie. you supply the
whole file name), so the extension is up to you. In the other
(used where one name is used for input and output files, or where
there are multiple output files), the program adds the extension.
In the documentation this should be indicated by calling it a
"base name".
