I corrected the DPI settings on both of my Laptops (117dpi on 15"
SXGA+, 145 on 12" SXGA+) but the blurring and wrong zoom-levels
remain.
Besides evince only Adobe Acrobat does the same mistake on the zoom-level.
xpdf, kpdf and okular do it right, its easy to tell since the
pages/images all have 1000 pixels width.

I dont think so because the other pdf-viewers produce a sharper image
at any zoom-level.

Is this blurring maybe cairo's antialiasing?
I also observed some other PDFs which get no antialiasing at all but i
have no idea why (they are scanned books as well).
