Snapshot actually calls 'scrsave' as directed by your PATH environment. So make the following file and save it as 'scrsave' in the directory your working in. Then start up /usr/sbin/snapshot. All scrsaves done in snapshot will be run through the filters you put in your scrsave. #!/bin/csh # Make scrsave save a black and white image, then # scale it by .75 # /usr/sbin/scrsave __tmp.rgb $2 $3 $4 $5 -b /usr/sbin/izoom __tmp.rgb $1 0.75 0.75 -w 1 /bin/rm __tmp.rgb By the way, this works for the showcase image gadget too. Only wish showcase had a way to extract images so you could edit them. -Tom Benoist benoist@netcom.com
