hi:
guys
when I tried to rotate sample.gif whose depth is 1 ,with 0.1 degree ,I found that ImageMagick implicted convert the depth to 8.and the output image became blur a little. but if rotate it in ps with 0.1 degree in the index mode.the output image still remains clear.could any buddy help out ....thanks very much..

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.

thanks for the advise! anthony
the line previously I used below:
convert -rotate 0.1 sample.gif output1.gif


I am gonna test the method you told me ..
