logo.png contains copyrighted material without license to redistribute

[kapouer]

Hi,
if you have a look inside it:
identify -verbose logo.png
you'll see it contains

  Profiles:
    Profile-icc: 3144 bytes
      Description: sRGB IEC61966-2.1
      Manufacturer: IEC http://www.iec.ch
      Model: IEC 61966-2.1 Default RGB colour space - sRGB
      Copyright: Copyright (c) 1998 Hewlett-Packard Company

The copyrighted ICC profile has no license, hence you can't know if you're allowed to redistribute that file or not.
You can either edit the file, or just remove it.

Hi @kapouer I accepted the TOS at the bottom of the page here http://www.color.org/srgbprofiles.xalter

so we are good to go!

[kapouer]

You are good to go - but not distributors that stick to open-source principles:

To anyone who acknowledges that the files "sRGB_IEC61966-2-1_no_black_scaling.icc" and
"sRGB_IEC61966-2-1_black scaled.icc" are provided "AS IS" WITH NO EXPRESS OR IMPLIED
WARRANTY, permission to use, copy and distribute these file for any purpose is hereby granted
without fee, provided that the files are not changed including the ICC copyright notice tag, and
that the name of ICC shall not be used in advertising or publicity pertaining to distribution of the

For one thing: provided that the files are not changed including the ICC copyright notice tag - this is not the terms of free software...

I'm pretty sure the ICC does not own all images that you use their standard color profiles in. If I'm wrong on this one, it would be quite the discovery though, and you should write about it and/or ask a lawyer asap, because a whole lot of people use standard ICC color profiles all over the internet.

[jamesplease]

lol

[kapouer]

This is absolutely not about the whole image being owned.
The only part that is copyrighted is the embedded ICC profile itself.
The Terms of Use explicitely says that a part of your png file is not allowed to be modified.
The requirement of free and open-source distributions like debian, fedora, etc... is that all
material can be modified without permission.

[jonassmedegaard]

Point here is ownership not of the image but of the color profile embedded in the image.

Do you agree that Hewlett-Packard Company owns that color profile?

Are you aware that in the context of web, not embedding a color profile at al is the equivalent of embedding an sRGB color profile, and is regarded as a best practice due to being more lightweight?

I suggest that you strip the embedded color profile - you don't need it, and others (distributors) have extra work stripping it when you don't.

What are some open source color profile options?

[jonassmedegaard]

Debian has a package - icc-profiles-free - unfortunately its copyright file is in a sad state, with its source URL being broken: http://metadata.ftp-master.debian.org/changelogs/main/i/icc-profiles-free/unstable_copyright

I believe best free reference ICC profiles are FOGRA.

Here are the locations I found good a few years ago when I last looked into this (not all of them are Free):

LOL Seriously?

Yes. We are way past April 1st.

Need to check if Photoshop `save for web` works that way...

I believe one of the very features of the "save for web" functionality is to (convert to sRGB colorspace, and) strip ICC profiles. Because the aim is to _optimize_ for web where sRGB is the default. - Jonas
