I wrote IM script for that long time ago. Should be in archives of the
list.

OK, found it. Looks like -fx changed between 6.2 and 6.3, after
necessary fixes it is here:

bgwidth=$(($width+15))
bgheight=$(($height+15))
swidth=$(($width+7))
sheight=$(($height+7))

convert -size ${bgwidth}x${bgheight}+0+0 xc:none \

	-draw "fill black line $(($width+2)),0 $(($width+2)),$(($height+2))" \
	-draw "image Over 1,1 $width,$height $name" final-$name

Commented version is for images which don't require 1pixel frame around
them, I use it rarely and not useful for Digikam manual photos.
