With p.ps from:

   http://www.logic.at/prolog/p.ps

when I do:

   $ emacs -Q p.ps

and press:

   C-c C-c - - - - - - -

the image shrinks, as expected. Then, when I quit Emacs and again do:

   $ emacs -Q p.ps

followed by C-c C-c, doc-view unexpectedly shows the small version
from the previous run. When I then press "-", it "shrinks" the image
so that the result is in fact larger than the just displayed image.

That's no bug.  When you fire up emacs again doc-view uses the cached
files, which are the small ones now.

Yeah, cause the resulution factor is at the default value again and
doc-view reconverts the doc using this default value x 0.95 or so.

I'm closing that "bug".

Bye,
