In fact
convert -sample 80x40 abbeyparkarch.gif s_abbeyparkarch.gif
automatically respects ratio, so only the y dimension is guaranteed
convert -resize 80 abbeyparkarch.gif s_abbeyparkarch.gif
respects ratio width 80
convert -resize x40 abbeyparkarch.gif s_abbeyparkarch.gif
respects ratio height 40
