Many thanks for your help, You have to use the Adobe Reader to view the PDF.
I’m afraid that I’m on Linux and I don’t have Adobe Reader installed.
Not just on Linux... (Adobe reader is a notorious security hole).
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 -- http://www.ousia.tk
