- Im not sure what you mean exactly. But hears a real useful trick for
- people who use snapshot.
-
- 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.
