In technical drawings and medical drawings/maps it is often common to explain certain features of the drawing by blocks of text that are arranged on its boundary. Bekos et. al. introduced the term boundary labelling to describe this special type of labelling and presented algorithms for automatic boundary labelling. BLer is a prototype tool aiming to automate the boundary labelling process. It targets the area of technical and medical drawings and incorporates implementations of boundary labelling algorithms presented in [1].
