Thanks to Anders Thulin (mcvax!helios!ath@uunet.uucp), my nroff-to-ps filter now supports "underline". The Red Book (pg 93) indicates that the FontInfo dictionary "may" contain the parametrics "UnderlinePosition" and "UnderlineThickness". Does this mean that use of these parametrics may be non-portable? Under what conditions is it portable or non-portable? My Nec LC890 does support these variables. Do other printers not support these? Do downloadable fonts "sometimes" support these? etc... thankyou.... tony.... -- +------------------------------------ | Tony Field ..uunet!utai!calgary!ajfcal!tony | Co-Design Information Systems Ltd. | Calgary, Alberta, Canada voice: (403) 266-3239

Be careful, when you are mixing fonts on one line of text, to compare underline positions and thicknesses of adjacent fonts. You may want to pick just one value for the whole line (indeed, perhaps the whole page), to avoid unsightly variations in underlines when there are font changes. It is purely aesthetics, and you may choose to disagree with my feelings, but at least think about it or print some tests and look at them. Glenn Reid Adobe Systems
