Use stdin and stdout with 2ff

It always seemed odd to have a file-argument for 2ff, given all other
farbfeld conversion tools operate on stdin and stdout only.
Given I received numerous e-mails on this matter I've decided to change
the usage to lessen the confusion.

Maybe there's a way to do some magic with tee(1), but I didn't bother
just yet.
To ease the transition, the number of arguments are checked and a usage
printed if arguments are given.

#!/bin/sh
FORMAT=`file -ib "$1" | cut -d ";" -f 1`
if [ "$#" -ne 0 ]; then
echo "usage: $0" >&2
exit 1
fi
TMP=$(mktemp)
cat > $TMP;
FORMAT=$(file -ib $TMP | cut -d ";" -f 1);
case "$FORMAT" in
image/png) png2ff < "$1" ;;
image/jpeg) jpg2ff < "$1" ;;
*) convert "$1" png:- | png2ff ;;
image/png) png2ff < $TMP ;;
image/jpeg) jpg2ff < $TMP ;;
*) convert $TMP png:- | png2ff ;;
esac
rm $TMP;
