<br>
Attached find<br>
(1) a PDF file which looks (to my eyes) much better with Acroread than<br>
with evince (and various other PDF viewers)<br>
(2) Two screen captures of the 30 pt / 20 pt / 10 pt text,<br>
one for Acroread and one for evince. Both of them claimed to be<br>
showing the text at 100% scale. I am using a 163 DPI screen, FWIW.<br>
(3) Two captures of xmag showing the 20 pt / 10 pt text.<br>
<br>
I will say that I am happy (happy enough, anyway) with how larger<br>
sizes get rendered by evince. However, you can clearly see<br>
differences with the 10pt font. The bottom of the '0' as seen in the<br>
xmag image is very weak, the top is weak as well. And the general<br>
brightness of the 10 point text is reduced, which does nothing for its<br>
legibility.<br>
<br>
The xmag images show that Acroread is doing sub-pixel rendering, but<br>
evince is not. (No-one has commented on this... does evince to SPR<br>
for anyone? Perhaps I have something configured incorrectly on my<br>
system.<br>
<br>
Anyway, perhaps people can chime in with how all these things look to<br>
them. Maybe its my eyes.<br>
<br>
Cheers.<br>
<br>
