Argyll CMS documentation index (V1.8.0)

Introduction

This is Version 1.8.0, a feature and bug fix update to V1.7.0. The first public release of icclib was in November 1998, and of Argyll 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.

An Introduction to Color Management

A great introduction for non technical people is Steve Upton's The Color of Toast.

Operating Environments

Argyll is known to compile and run in at least the following environments:

but may well compile and run correctly in many more than this, including OS X 10.8.

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 Argyll CMS 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 ccmx (Colorimeter Correction Matrix) files for some display/colorimeter combinations.

Main Tools and the command line

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".
