[Inkscape-user] Trying to create a rubber stamp effect

Hi,

I have found this tuto about creating a rubber stamp effect:

http://howto.nicubunu.ro/rubber_stamp_inkscape/

It says I should do an intersection between the image and the calligraphic drawing, but for me it doesn't work.., I mean, Inkscape doesn't do any intersection..Of course I select both objects before trying the intersection.

I attach a file.
