From: clewis@ecicrl.UUCP (Chris Lewis) Newsgroups: comp.text.desktop,comp.fonts,alt.sources Subject: TeX PK to HP SFP format font conversion (1 of 2) Message-ID: <851@ecicrl.UUCP> Date: 17 Sep 90 16:17:28 GMT Since this keeps coming up, and psroff hasn't apparently made it to comp.sources.unix, here's the utility to convert PK fonts to HP SFP's that Liam mentions: Shell archive - cut here - #!/bin/sh sed -e 's/^X//' > README <<\!BLOTTO XThis distribution is that of pk2sfp, which is a subset of Xthe full psroff 2.0 distribution. Psroff is a complete package Xto allow you to use CAT (aka "old") troff with HP Laserjet Xcompatible printers, Postscript and ditroff output drivers. XPsroff has a complete set of utilities for handling PK and SFP Xformat fonts. Pk2sfp converts PK and SFP fonts into SFP format, Xwhich can be useful outside of psroff. Psroff 2.0 is currently Xsitting in the queue for comp.sources.unix, but since people keep Xasking for pk2sfp, I've decided to release this subset separately. XIt also includes pktype, a program for printing the characteristics Xof PK and SFP fonts. This distribution corresponds to Proff 2.0, Xpatchlevel 3, though, patches 1 thru 2 did not touch any of this code, Xand patch 3 was exclusively to make standalone pk2sfp possible. XPatch 3 to psroff has not been distributed yet. X XTo build: modify defs.h as appropriate and type "make". X XThe man page for pk2sfp is uneditted from the psroff distribution Xand refers to some things that aren't in this release: X X 1) pk2ditwid (creates ditroff-like width tables) X 2) pk2ps (converts SFP's and PK's to Postscript fonts) X 3) "partial" pk2sfp downloading stuff (-p). X XIn the interests of saving space, they have been omitted. If Xyou need them, pick up the full Psroff release (they need tables Xbuilt by other major parts of psroff). Further, you'll see some Xstrange things that look like ``%%LJF%%''. If you had the full Xpsroff release, they'd expand into configuration dependent directory Xnames, but they're not builtin to any of *this* code. X XIf you intend to do any substantial work with PK and SFP fonts, XI suggest that you get the whole psroff package. X XThis distribution is unsupported. However, psroff 2.0 *is*, and patches Xto psroff may be applicable to this distribution.
