Hi. I don't know the imagemagick solution, but there is another. A simple
shell script can do this one.

Convert your picture to ppm/pnm and then use pnmscale (with -xysize
option, see man page) which conserves aspect ratio. An then convert
pnm/ppm back to whichever format u want. See netpbm package.
