Roger, I use latest gsview and ghostscript. Gsview does exactly what you say, but epstool refuses to work properly with noninteger bounding boxes. Just to inform everyone about how problem #1 has been solved: Antoine Terracol sent me an ado-file which returns integer bounding boxes.

This seems to be what is happening. I combine 5 graphs and have some white space below my picture. But now, since my bounding boxes are integer, it is one line at the DOS promt to correct the bounding box: epstool -b -c -onewpic.eps oldpic.eps Thanks a lot for all replies, best regards, Eva Poen * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
