| Abstract | When Donald Knuth made virtual fonts part of the general TEX repertoire at the end of 1989 151, at the same time as extending both rn and METAFONT to support 8-bit input, it immediately became obvious that the world needed a new standard for the layout of fonts. This is not the place to review the discussion of what characters should be in a generalized 256 character text font (see 14, 3]), nor to pass judgement on the proposed solution, finalized at the rn Users Group meeting in Cork in September 1990, but rather to demonstrate how the layout can be implemented using POSTSCRIPT fonts (Donald Knuth and Tom Rokicki have already shown how to create POSTSCRIPT fonts in the original TEX layout, using virtual fonts, implemented in the latter's distributed af m2tf m ~rogram) . To remind ourselves what we are aiming at , Fig. 1 shows the new layout using the Extended Computer Modern Roman font (dcrlO, from the dc family created by Norbert Schwarz). Some characters needed extra work with METAFONT, but most were created from existing building blocks, and we shall follow this approach with the POSTSCRIPT fonts. The set of procedures described below has only been made to work in a limited environment, but the principles can be used for most common dvi-toPOSTSCRIPT drivers, so long as they support virtual fonts. Our assumption in what follows is that we are using Rokicki's afm2tfm program (to convert Adobe font metrics to TEX font metrics) and the same author's dvips program, currently the only public domain dvi to POSTSCRIPT program to implement virtual fonts. The system has only been tested under Unix and OS/2, but should be easily portable, consisting of a program written in C, and the standard m w a r e programs. Examples are given in a Lucida Bright font. |
