Ditroff stands for Device-Independent Troff and, among its other features, provides for the inclusion of graphics in the middle of text by the use of languages like pic and ideal. I've run into a couple of snags, though, and I wonder if anyone out there has any insight into them. The main problem seems trivial but for certain applications simply can't be ignored: ditroff screws up square roots (as produced using the preprocessor deqn). Specifically, the horizontal bar which should appear over the expression to be sqrted is too low and is dashed rather than solid. It appears that the "root extender" character \(rn is somehow at fault. I've used rst2ch to browse around in the likely raster files, but I can't even find the \(rn character to check it. Any ideas where \(rn should be or how I could fix the problem? This may or may not be related to another difficulty which I've already solved: Because of licensing complications, the ditroff distribution tape we received didn't include raster files for our output device, an Imagen Imprint-10. The distribution tape did include width files, however, which contained at least a few minor inconsistencies with the raster files we got from Imagen -- specifically, the width files thought that certain fonts should contain ligatures that weren't there. Once I had identified the problem, it was relatively simple to amend the width files to eliminate the hallucinatory ligatures. Any hints, hunches, or suggestions would be appreciated. Also, if folks want to show off their snazziest illustrations using pic, I'll be happy to ooh and ahh. --- Prentiss Riddle ("Aprendiz de todo, maestro de nada.") --- {ihnp4,harvard,seismo,gatech,ctvax}!ut-sally!riddle
