In KDE 4.10 not all pdf's are readable. But one the text is way too light.
Making for difficult if not impossible to read in Ockular.
Is this a Theme issue? as using a dark theme. or a pdf issue?
Seems to be a pdf issue as others look fine.
And how can one change a pdf text color? as it seems Okular doesn't have much in way of setting reading preferences.
Program that allows editing these kind of things and re-saving them?
