License on utils/jpgicc/iccjpeg.c? about little-cms

[mm2]

Hi,

This file was authored by Tom Lane, from IJG. He never stated any
license, but allowed me to distribute the file.

Quoting Niklas Haas [email protected]:

What exactly is the license on this file? There does not seem to be
any licensing information included in the file itself or in its
directory. Does that mean the LittleCMS 2 license applies?

I'm confused because eg. Chromium includes it under the IJG license:
https://chromium.googlesource.com/chromium/chromium/+/master/third_party/iccjpeg/LICENSE with the reasoning being that it was authored by a member of the IJG group, however I did not find this file included in any of the IJG's jpeg
distributions.

I would love to use this code, but I can't really do that without
knowing for sure what the license on it is.

I've contacted Tom Lane to clarify the situation.

The file was originally authored by Todd Newman and intended for libjpeg, but the proposal got lost sometime in 1997 when Tom left the IJG. Still, based on this history, the IJG license is appropriate.

I would propose including the IJG license information in the folder it resides in, to help clarify to future users. You can find it inside the README file of http://www.ijg.org/files/jpegsrc.v9a.tar.gz, but I've included the relevant portions verbatim:

In plain English:

1. We don't promise that this software works.  (But if you find any bugs,
   please let us know!)
2. You can use this software for whatever you want.  You don't have to pay us.
3. You may not pretend that you wrote this software.  If you use it in a
   program, you must acknowledge somewhere in your documentation that
   you've used the IJG code.
