But using (an old version of) Adobe Distiller instead of GS to convert the .ps to .pdf, the problem does not occur; therefore, it seems that GS is behaving differently from Adobe Distiller.

I presume this might be called a dvips bug, or at least it might be fixed in dvips. When using "epstopdf + pdflatex" or "latex + dvipdfmx" the problem does not appear. Another contributor in " comp.text.tex" confirmed that, when including eps files created by a different procedure but containing metainformation, he encountered the same problem. <BR>The problem is easy to reproduce, but so you may check it, I attach here 3 files: <BR>(1) "<A href="http://gr.gp">gr.gp</A>", a gnuplot script file.<BR>(2) "gr.eps", the resulting eps file.<BR>(3) "problem.tex", the LaTeX that gives rise to the problem.<BR>I process " problem.tex" with latex (or pdflatex --output-format=dvi), then dvips (with or without -z), and finally ps2pdf.

I presume one might tweak dvips to reproduce only the hyperref information in this case, or rather to ignore the metainformation coming from the included graphics files. <BR>Thanks for your help.<BR>Best regards,<BR>Gual<BR><SPAN><DIV><gr.gp></DIV></SPAN><SPAN><DIV><gr.eps></DIV></SPAN><SPAN><DIV><problem.tex></DIV></SPAN></BLOCKQUOTE></DIV><BR></BODY></HTML>
