# set icon and temporary photo location
icon="$HOME/.config/i3/icon.png"
tmpbg='/tmp/screenshot-temp.png'

# cleans up if screenshot already exists because scrot won't overwrite
rm -f $tmpbg

# takes a screenshot of the current screen (relies on 'scrot' package)
scrot "$tmpbg"

# blur the screenshot by resizing and scaling back up (relies on 'imagemagick')
convert "$tmpbg" -filter Gaussian -thumbnail 8% -sample 1250% "$tmpbg"

# overlay the icon onto the temporary screenshot
convert "$tmpbg" "$icon" -gravity center -composite "$tmpbg"
