concrete and ccfonts packages render math symbols not in vector form but as bitmapped. How can I get rid of this?
I added an example snapshot from free latex math fonts,Fig.4 which seems to have same behavior . You can see the difference in math and text characters. I have no problem with Euler version of math symbols

concreteif you use LuaTex or XeTeX. – morbusg Dec 10 '11 at 22:21
