OTOH, we found that GeoServer for instance didn't have this type of problematic labels because it simply detected the overlapping chars and skipped those labels, leaving room for other/better labels to fall around the same spot... leading to a better looking map. This ticket is about implementing a similar mechanism to detect overlapping characters in ANGLE FOLLOW chars and skipping those labels. Note that ticket #2221 started discussing this option as part of a wider discussion of curved label problems, but since #2221 aims to address a different issue using b-spline to smooth the lines an get less erratic char positioning along valid curved labels, I decided that the ability to skip invalid labels with overlapping chars along very sharp curves should get its own ticket (and eventually RFC)." defect closed normal 6.0 release Documentation - MapServer unspecified normal fixed jmckenna sdlime tbonfort woodbri
