Given a downloadable PostScript font (PS and AFM file), is it possible to create a SmallCaps font for it, by munging the AFM file only? This font must be used by several different applications, so specific solutions (e.g. TeX virtual fonts), though helpful, are not what we are looking for. Any help is appreciated.

I don't think you can affect the display of the font by modifying the AFM file. It seems to me that the obvious way to implement it is with a Composite Font with an FMapType of 6. Unfortunately, that's a Level 2 feature so most printers still don't have it -- Rich

No. Given the PostScript font, you can create another PostScript font, which is `small caps'. It's pretty straight forward. I did it as one of my first non-toy PostScript programs several years ago, when the DVI-to-PS we were using didn't support small-caps. Since then I've seen other people's solutions to the same problem (there's now one in every dvi2ps, dvips, dvitops, etc) and like most of them better than mine. As I recall there were a number of small gotchas that I didn't think of the first time through. One was ligatures. You should be able to take the original AFM file and produce a new one with font metrics based on the original, assuming the small-caps were produced using a fixed scaling factor (eg. 0.6). You can also produce kerning info for the new small-caps by scaling the ones for the big-caps. However, I think you're stuck for the big-cap-to-small-cap kerning pairs. The old AFM just doesn't have the information you'd need to figure out the kerning between a big-cap-T and a small-cap-H. -- Bob Tinkelman, Cambridge Computer Associates, Inc., 212-425-5830, bob@camb.com
