Many thanks for your answer.
If I include some transparent stuff on a light background (i.e. a
metapost figure on a light gray screen), there's a visible rectangle around it (on the screen). Yes, it's unfortunately normal at least in Acrobat 7 and 8, also in Apple's PDF viewer (in Preview, Mail etc.). In my experience esp. transparent (or flattened) elements show a fine white border - but if you zoom in, it stays the same fine line or sometimes disappeares. And it never shows in print.
However, what I meant was slightly different: not a tiny white line around but a solid (full) rectangle with light gray background. You can see it here: http://www.econ.muni.cz/~qasar/tmp/inst-slide02.pdf, page 3 (the ugly background in the figure on the page 2 is my fault).
isn't that alpha channel stuff? i never looked into that but your marx picture does not have the gray background .. maybe compare the internals of these graphics adn see what happens inside ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
