All the rotation methods 'blur' the image some more than others

What method did you use for rotation?

If you want to preserve 'bitmap' handling use -distort with an appropriate interpoation setting
See examples under interpolation of a rotated line
http://www.imagemagick.org/Usage/misc/#interpolate_line


ASIDE: Also a new less blurry 'distort' (for default settings) will be released soon, though that does not effect 'interpolated' distorts.
