Hi all,

I found that the copyright notice is inserted by ghostscript when converting a
PDF chart to a JPEG image.  Artifex Software, Inc. is one of the copyright
holders of Ghostscript.

The image in fastqtl looked a lot like a R plot and I verified that R did not
create JPEG files with copyright statements in.  A search on Internet showed
that Artifex commercialises some image converters.  A second search gave me
a command to convert from PDF to JPEG with ghostscript and voilà! here is how
you can similarly copyrighted JPEG files.

# Create a PDF file; here I use R to plot random values.
Rscript -e 'pdf("foo.pdf");hist(rnorm(50), col="red"); dev.off()'

# Convert it to JPEG with Ghostscript.  Exit with Ctrl-D.
gs -dNOPAUSE -sDEVICE=jpeg -r144 -sOutputFile=foo.jpg foo.pdf 

# Show the copyright statement:
hexdump -C foo.jpg | grep -C3 -i copyr

Indeed, ghostcript ships ICC color profiles and if I undestand well, inserted
the "default" one.

$ hexdump -C /usr/share/color/icc/ghostscript/default_rgb.icc | grep -C3 -i copyright

Ghostscript is distributed in main, but I could not find a clear license statement
for the color profiles...
