Hi, In groff, the .ne, .nw, .se and .sw corners of a line are all placed at the start of a line. I don't have access to the original pic but I do have access to the Plan 9 pic which places these four corners at the centre of the line. I imagine that groff's pic should behave as the pic that came with the 10th edition Unix.
This appears to be due to the line_object class not overriding the north_east(), north_west(), south_east() and south_west() methods of the object class (the default implementations return the object's origin which, for a line, is its start point). However, since these corners do not make much sense in the context of a line, maybe this cannot be considered a bug. The attached me document at the end of this email illustrates the problem. Process with "groff -p -me -Tps jb008.nr > jb008.ps". The version of groff I tested with was 1.18.1 but the code referred to is version 1.19.2 so I suspect the problem (if it is indeed a problem) is still present. Regards, James
