There have several requests for methods to augment Mathematica graphics with labels and arrows. Some suggestions have been to use PostScript-generating applications like Adobe Illustrator. This is fine provided the labels are to be linear text, but not so good for mathematical expressions. If the ultimate aim is to use TeX, then there are some useful macros by Kristoffer H Rose, Univ. of Copenhagen, Denmark ( kris at diku.dk ). They come with their own fonts for drawing lines and arrowheads at 128 different directions, and quarter circles at a wide range of point-sizes. The distribution available from ftp.diku.dk [129.142.96.1] includes macros, manual, .pk fonts and Metafont sources. None of Kris's manual examples deal with the graphics labelling problem directly, but these macros are indeed well-suited to this problem. I have just finished preparing Macintosh font suitcases for use with TeXtures, in a range of sizes for both screen display and laser printing. My examples and fonts are now available by anonymous ftp. The remainder of this posting is the README file ... *************************************************** xyPic.README from /pub/maths/TeX/XYpic @ ftp.mpce.mq.edu.au by Ross Moore, ross at macadam.mpce.mq.edu.au Dept of Mathematics Macquarie University Sydney, Australia, 2109 Files to be found in this directory relate to the use of XYpic macros for creating labels & arrows to parts of graphics within TeX documents. Also there are font suitcases for use with the TeXtures application on a Macintosh computer. ************************************************************* The XYpic macros were written by ... Kristoffer H Rose kris at diku.dk Univ. of Copenhagen Denmark ... they can be obtained by ftp from ftp.diku.dk [129.142.96.1]. This ftp site contains two archives containing... 1. macros + examples + .pk fonts in a range of useful sizes 2. macros + examples + Metafont descriptions the manual is also available as a PostScript file. The file xypicready.tar.Z is a copy of archive 1 above. ************************************************************* There are many maths applications for these XYpic macros: e.g. Commutative Diagrams, Graph-Theory, finite State-machines Another use, which does not appear in the manual, is in labelling graphics with arrows to indicate special features. There have been many requests in Internet news-groups for such capabilities, in particular for Mathematica-generated graphics. One of the files here gives an example of how XYpic can be used to perform this task most admirably. Also there are suitcases of font files for use with the superb TeX implementation TeXtures, from Blue Sky Research. ************************************************************* Where appropriate files have been archived from a Macintosh using 1. Stuffit v1.5.1 ** -> **.sit 2. BinHex'd v 4.0 ** -> **.hqx 3. compressed under Unix ** -> **.Z ( hence the file names of the form: **.sit.hqx.Z ) ************************************************************* Description of files: XYfonts.sit.hqx is a Stuffit archive containing font suitcases for Macintosh/TeXtures 1. XYfonts uncompressed size = 824k most of the fonts, design size = 10pt screen sizes : 10pt 12pt 20pt 24pt laserwriter : \magstep0 ( = 42pt), \magsteps .5,1,2,3,4,5 2. xymisc uncompressed size = 981k font for large circle pieces, design size = 10pt screen sizes : 10pt 12pt 20pt 24pt laserwriter : \magstep0 ( = 42pt), \magstep1 ( = 50pt) (larger sizes get to be enormous !!) 3. xymetrics uncompressed size = 5k font metrics for all XYpic fonts, for use with TeXtures. WARNING (technical, re fonts, Macintosh only ): The fonts NFNT resource IDs in these archives have been regularized so that different point-sizes of the same font have related IDs: ID = 128 * family# + pointsize except where this clashes with other TeX fonts similarly regularized, in which case a nearby ID has been chosen. Check for ID clashes on your system. Use ResEdit or some other utility to alter the NFNT and FOND resources. xyPicTest.sit.hqx is a Stuffit archive containing examples relating to XYpic. 1. xyPicTest.tex (uncompressed size = 34k, incl PICT graphic) TeXtures document containing a PICT graphic with parts labelled using arrows pointing in various directions. Only the command \picture dependent on TeXtures, the remainder of the code is Plain TeX + XYpic . Only the \special{picture ...} command is specific to TeXtures, so this should TeX on other systems, but without the graphic. (The graphic was generated in Mathematica.) 2. xyPicTest.ps (uncompressed size = 87k) PostScript version of the above tex-file: xyPicTest.tex generated from TeXtures. This contains the AppleDict, so should print correctly if downloaded to any PostScript printer. 3. testxyfonts.tex (uncompressed size = 22k, incl DVI2 resources) TeXtures document which generates tables to view the complete suite of xyfonts at a particular \magstep. The code is Plain TeX + XYpic . xypicready.tar is a unix tar archive containing the XYpic macros + examples + .pk fonts. This file was created by Kristoffer H Rose; it has been copied from the ftp site at ftp.diku.dk [129.142.96.1] . ***************************************************** I would be most interested in any novel or elegant uses you find for these macros and fonts. Use and enjoy. Ross Moore.
