Many thanks for your reply, Alan.
\startnegative is the way of doing it, as Wolfgang suggested. Don’t
worry, I won’t install Adobe Reader.
Ghostscript also implements what actually is the /TR (transformation)
entry for /ExtGState (graphics state) dictionary. (I was wrong in my
previous message.)
Only poppler and mupdf should implement it.
Many thanks for your help,
Pablo
