Quoting the e-Mail I posted yesterday on poppler at lists.freedesktop.org:

I have several PDFs which consist of low-resolution scanned images.

These PDFs are rendered better and /much/ more readable in Adobe Reader
(e.g. Version 8.1.3) than in Okular or in other applications using
libpoppler version 0.10.5.

The reason appears to me to be a much better antialiasing technique in
Adobe Reader.


Once again, this report does NOT concern the rendering of fonts, but the
rendering of images!

I've uploaded an example file and a screenshot with explanations for you:

I'm using Ubuntu Jaunty 9.04 AMD64.
