Oops. You've seen my Marx pictures. I'm ashamed I was caught. :-( (Well, no, I'm not a Marxist.) :-)
I think the alpha channel is not the cause, since I can see the light gray rectangles under the MetaPost figures, not under PNG with transparency. I don't know how precisely the transparency is done in the MetaPost, but I guess there is no background under curves and shapes I draw in the MetaPost. At least there is nothing visible in the figure on the page 10 of http://www.econ.muni.cz/~qasar/tmp/inst-slide02.pdf. However, some background is visible under all MetaPost figures on pages 3 to 6. The background under the figures is different from the background around them. Or don't you see it? Then it might be a problem just under some versions of the AdobeReader, perhaps only under Linux. Many thanks for your answers. Have a nice day.
