tiffinfo gives me the following output. I want to change the
Resolution from 299,300 pixels/inch to 400,400 pixels/inch (notice
that I want Image Width and Length remain the same, so -resample
option is not what I want). Does anybody show me how to do so with
convert? Thanks!

Re: Change the resolution of tiff files
use -density and -units. see http://www.imagemagick.org/script/comma ... hp#density and http://www.imagemagick.org/script/comma ... .php#units
convert xxx.tif -density 400x400 -units pixelsperinch out.tif
convert xxx.tif -density 400x400 -units pixelsperinch out.tif
