This DCL archive contains all the required bits and pieces for preparing pictures for plotting by TeX. When executed, the archive creates the following files: o BLURB.TXT this file o HALFTONE.TEX user-level documentation (for LaTeX) o PICTURE.TEX picture from TeXPIC used by HALFTONE.TEX o TEXPIC.FOR the software. Note that there are two versions of TEXPIC in this file, one for VMS and another which is a little more portable. o HALFTONE.MF Don Knuth's halftone font If you intend to produce pictures of size >= 256 x 256, you'll need to expand TeX's memory (see my article in TUGboat vol 8 no 3 for more details). I can supply a TeX change file for VAX/VMS which effects this change (and provides an editor interface) either by e-MAIL or on tape. Contact me for more details. If you want to use this software, but you're not a TeX guru...find someone who is! He/she will be able to generate convert the Metafont source for the halftone font (HALFTONE.MF) to a form acceptible to TeX, and put it in the right directories for you to use. I can supply outline help, but the font generation process tends to be horribly site-dependent. Sorry. If you have any trouble with the software, please let me know (it's not quite the same as the version I use myself). I'm particularly keen to receive feedback from non-VMS sites. `Alien' (ALIEN @UK.AC.ESSEX.ESE on JANET)
