Crystallographic resources

A font for crystallographic symmetry elements

A font, cryst, has been created by Ulrich Müller for displaying crystallographic symmetry axes in the style of the space-group diagrams in International Tables for Crystallography.

Instructions for use in TeX applications

Installation

cryst.mf contains the METAFONT file to produce the pk files. cryst.afm and cryst.pfb contain the PostScript Type 1 fonts (for PostScript or pdf output).

Create a new subdirectory cryst1 in your directory of the tfm (tex font metrics) files (e.g. \texmf\fonts\tfm\public\cryst1 for MikTex under Windows or /usr/share/texmf/fonts/tfm/cryst1 for Linux RedHat). Copy cryst.tfm into this directory.

Create a new subdirectory cryst1 in your directory of METAFONT files (e.g. \texmf\fonts\source\public\cryst1 or /usr/share/texmf/fonts/source/cryst1). Copy cryst.mf into this directory.

Create a new subdirectory cryst1 in your directory of afm (Type 1) files (e.g. \texmf\fonts\afm\cryst1 or /usr/share/texmf/fonts/afm/cryst1). Copy cryst.afm into this directory.

Create a new subdirectory cryst1 in your directory of pfb (Type 1) files (e.g. \texmf\fonts\type1\cryst1 or /usr/share/texmf/fonts/type1/cryst1). Copy cryst.pfb into this directory.

Tell dvips (for PostScript output) where to find the files. To this end, insert the following line into the file config.ps:
p +cryst1.map
(config.ps is in a directory like \texmf\dvips\config or /usr/share/texmf/dvips/config). If you use pdfTeX, insert
map +cryst1.map
to your pdftex.cfg file (in \texmf\pdftex\config or /usr/share/texmf/pdftex/config).

Create a new file cryst1.map in a new subdirectory of the directory of map files (e.g. \texmf\dvips\cryst1 or /usr/share/texmf/dvips/cryst1). The file cryst1.map consists of one line:
cryst cryst1 <cryst.pfb
Finally, tell TeX which new files and directories exist. This is done by a command like

initexmf -u 

for MikTeX under Windows, or run texhash under root in the shell of Linux RedHat.

Usage

Include the following commands in the preamble of your document:

\DeclareFontFamily{U}{cry}{\hyphenchar\font=-1}
\DeclareFontShape{U}{cry}{m}{n}{ <-> cryst}{}
\newcommand{\cry}[1]{{\usefont{U}{cry}{m}{n} \symbol{#1}}}

To produce the graphical symbol number n in the text, use the command

\cry{n}

n is the number of the symbol in the list of symbols (see file cryst1.pdf). For example, the command \cry{41} will produce the symbol for a 4_1 axis.

Use 

\put(..,..){\makebox(0,0)[Pos]{\cry{..}}}

commands to position the symbols in \put commands in picture environments (cf. file cryst1.pdf).
