I would like to draw a pgfpicture and besides to it add some picture file.
Using the code below, I get the following error message:
Package pgfkeys Error: I do not know the key '/pgf/decoration/\p gfkeyscurrentname ' and I am going to ignore it. Perhaps you misspelled it. See the pgfkeys package documentation for explanation. Type H for immediate help. ... l.97 \Item R 2pt (180:-40)
What do I have to correct or add in the following code?
