Thanks, it worked.
I used gmic inside gimp 2.8 to inpaint the red areas. I tried to
use the command line to achieve the same result as a 16bit tif.
However, I did not achieve my aim for several reasons:
-
The command line did not produce the same result
like the gimp plugin. (I tweaked the command line and
used the same parameters as the plugin.) -
The command line did not produce a 16 bit tiff
which is readable by othe programs. -
The command line changed the color profile.
