I only managed to achieve this effect with extremely large font sizes, which may or may not be related (it could also be that I didn't find the `magic' \hsize). If you force the characters to shrink even more, for example by setting \hsize to 120pt in the latter test file, the unexpanded font will be used, thus printing the characters over each other. Regards, Robert PS. I didn't bother to create expanded fonts, so I cannot tell whether it depends on the autoexpand feature. ---------------------------------------------------------------------- Comment By: Nobody (None) Date: 2004-09-23 03:32 Message: Logged In: NO Obviously, I filed this report too early. Sorry about that. It is not a pdftex bug, but appears to be a bug in Acrobat Reader 6. (Just to tell you what I saw:) At zoom level 200% or larger, the font most shrunk (Extend_100) is not visible on screen. That is, in the first example, I only see "See y e", in the second, nothing at all. However, if I zoom out, the characters re-appear. Sorry for not zooming out earlier. Regards, Robert. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=199&group_id=106
