Tilman Hausherr commented on PDFBOX-4090:
-----------------------------------------
I'm not sure it is an issue at all, I never get the blurry rendering you get.
What I did get is that the 1.6 rendering was darker, but 1.6 may have been
using a different strategy.
I tried with 2.0 and the 100% rendering is kindof too small, but at 200% it
looks nice. Your code has 350 dpi so that is about 500%. Did you reduce it for
the screenshot?
Did you create the file yourself or did you receive it from a client? If you
created it yourself, why not use Courier Bold instead of Courier?
