Like Gavin, I've written one too.  A little simpler though and pushing
the brunt of the work on nawk.

#!/bin/sh
# Script to take an image and zoom it to a specific size
# Arguments:
#   zoom img newimg xsize ysize

if test $# -ne 4 ; then
    echo "Usage: " $0 " image new_image xsize ysize" 1>&2 # send usage to stderr
    exit 2
fi

img=$1
imgnew=$2
newx=$3
newy=$4

istat $img | nawk '
{
    if (NR == 2) {
        system("izoom '$img' '$imgnew' " 'newx' / $2 " " 'newy' / $2);
    }
}'
