We consider directed figures defined as labelled polyominoes with designated start and
end points, with two types of catenation operations. We are especially interested in codicity
verification for sets of figures, and we show that depending on the catenation type the question
whether a given set of directed figures is a code is decidable or not. In the former case we give a
constructive proof which leads to a straightforward algorithm.
