<div class="">On my Raspberry I just installed the Debian icc-profiles-free package<br class="">
and now there is a file<br class="">
<br class="">
/usr/share/color/icc/ghostscript/srgb.icc<br class="">
<br class="">
If Debian considers ghostscript/srgb.icc as free, isn't it free enough<br class="">
for TeX Live as well? The file contains<br class="">
<br class="">
"Copyright Artifex Software 2011"<br class="">
<br class="">
Is this license appropriate for TeX Live? I think so because<br class="">
otherwise neither Debian nor TeX Live can provide Ghostscript.<br class="">
<br class="">
Debian also provides a file<br class="">
<br class="">
/usr/share/color/icc/sRGB.icc<br class="">
<br class="">
which obviously comes from LCMS and contains<br class="">
<br class="">
"no copyright, use freely"<br class="">
<br class="">
Nicely said. Sounds like "public domain" at a first glance. But who<br class="">
is the author and where does the stuff come from?<br class="">
<br class="">
After all, I think that if all GNU/Linux distributions already provide<br class="">
Ghostscript, there is no obvious reason not to ship a file which is<br class="">
part of it with the pdfx package.<br class="">
</div>

<div>Probably best is to ship a copy of this (i.e., one of these – which one?)</div>
<div>in the …/tex/latex/pdfx/ directory.</div>
<div><br class="">
</div>
<div>Another possibility is to specify the full path to it, where needed in</div>
<div>the source of pdfx.sty .</div>
<div>The problem with this is that it needs to work on all platforms, so the</div>
<div>syntax of the path (or the path itself) could be different.</div>
<div>Maybe Ghostscript isn’t even installed in some cases, since GS normally</div>
<div>isn’t needed when pdfTeX is the engine ?</div>
<div><br class="">
</div>
<div><br class="">
</div>
<div>But there is one aspect of this that I don’t have the expertise in color usage to decide.</div>
<div>How different are the various profiles?</div>
<div>What is the difference between them? Does it matter?</div>
<div>If we make a choice, then there should be a reason for it, concerning the actual</div>
<div>colour output, either on-screen or when printed with different devices.</div>
<div><br class="">
</div>
<div>It would be good to have some explanation included within the pdfx documentation,</div>
<div>addressing this issue. That is, saying when it is best to stick with the default,</div>
<div>and when it is advisable to apply a different Colour profile, perhaps with some</div>
<div>examples of when alternatives are either useful or needed.</div>
<div><br class="">
</div>
<div>Who can help with this?</div>
