Has anybody had any experience with the automatic positioning of labels on a objects in a graphical image? What I'm really after are some techniques of placing labels on a visual object keeping in mind that the label must not overlap other text or other visual objects with greater priority, and a method of placing text inside an object in such a way that it is central. The label inside the object must be placed in the centre of the largest possible box inside the object proportional to the dimensions of the text. Thanks (Please post, don't mail if possible) inb300campbe@redgum.qut.edu.au

This has been an active research area for several years. The earliest work I know of is John Ahn here at RPI, who was PhD'ed under Herb Freeman, who is now at Rutgers. There have been other papers in the cartographic conferences. Anyone current in GIS (Geographic Information Systems) or cartography should know of them. Here is the RPI online library record for Ahn's thesis: BY: Ahn, John K. Rensselaer Polytechnic Institute. Mathematics Department. TITLE: Automatic map name placement system.

Though I haven't used it myself, a possibly useful article (with numerous references) is "Cartographic Name Placement with Prolog" by Christopher B. Jones. It appears in the Sept. 1989 issue of IEEE Computer Graphics and Applications.
