This is the file thaifont.txt of the CJK macro package ver. 4.8.4 (18-Apr-2015). Thai font support in the CJK package ------------------------------------ Version 4.8.4 of the CJK package has improved support for Thai. This file describes how to install and use the fonts. Please refer to cjk-enc.txt how to set up cjk-enc.el (which automatically loads thai-word.el for finding word breaks). The directory structure in utils/thaifont/texmf already reflects the directory structure of a standard TEXMF tree, version 1.1. Example: utils/thaifont/texmf/fonts/enc/dvips/thai/c90.enc -> /usr/local/share/texmf/fonts/enc/dvips/thai/c90.enc To create TFM files for other Thai fonts, use the utility files in the `thaifont/tools' directory. Details how to do that can be found in `thaifonts/tools/INSTALL'. The file thaifont/tools/c90.etx gives the theoretical background on the used font encoding and ligature mechanism; a pre-formatted version can be found in CJK's doc bundle. Installation ------------ . It is assumed that you have already installed the main parts of the CJK package (as described in the doc/INSTALL file). . Get the latest fonts-tlwg package from http://linux.thai.net/projects/thaifonts-scalable and install the Type 1 font families `garuda' and `norasi'. You should use fonts-tlwg version 0.5 or newer. Note, however, that this bundle no longer contains pre-compiled AFM files; instead, they are generated (together with Type 1 and TrueType versions of the font) with a bunch of tools using a configure script and a Makefile. Recommended locations are TEXMF/fonts/type1/public/{garuda,norasi}/ . Examples: garuda.pfb -> TEXMF/fonts/type1/public/garuda/garuda.pfb norasi_bi.pfb -> TEXMF/fonts/type1/public/norasi/norasi_bi.pfb Note that the TeX metric files of font-tlwg bundle are incompatible with CJK's Thai implementation. Nevertheless, it is possible to use both at the same time if desired. This is the very reason that the Babel language support file of the CJK package is called `thaicjk.ldf', not `thai.ldf'. . Install all files from utils/thaifont/texmf in your TEXMF tree. This should be straightforward. . Font definition files for Thai are in CJK's texinput/thai directory. To simplify font handling with LaTeX, `gar' and `nrsr' are aliased to `cmr', `cmss', and `cmtt'. If you want to use other fonts, you have to adapt c90cmr.fd, c90cmss.fd, and c90cmtt.fd accordingly. . There are two possibilities how to make the Thai PostScript fonts known to the various DVI drivers (and pdftex). The recommended way is to include the files `garuda-c90.map' and `norasi-c90.map' in the `updmap.cfg' configuration script by adding the following two lines: Map garuda-c90.map Map norasi-c90.map Older versions of updmap which don't have updmap.cfg must be patched directly by adding the map files to the `extra_modules' variable: extra_modules=" garuda-c90.map norasi-c90.map " After executing updmap, the fonts are known to all programs which uses the map files. For dvips, you can also use the `config.norasi-c90' and `config.garuda-c90' files on the command line: dvips -P norasi-c90 ... This method doesn't work with pdfTeX (which doesn't understand the `-P' option). . Run mktexlsr or a similar program to update the TEXMF file database. Usage ----- Thai support has been fully integrated into the Babel system. For example, to have Thai as a secondary language and US English as the primary language, say \documentclass{...} ... \usepackage[thaicjk,USenglish]{babel} ... \begin{document} ... \begin{otherlanguage}{thaicjk} Thai text \end{otherlanguage} ... `thaicjk' changes the baseline stretch to 1.2, activates \frenchspacing, and modifies the \today command to use the proper Thai values and names. The just sketched outline works without cjk-enc also (but no word breaks are inserted automatically); you must then insert \addto\extrasthaicjk{\fontencoding{C90}\selectfont} in the preamble of your document to make Babel switch to Thai font encoding on entering the `thaicjk' language environment. For use of cjk-enc.el please read `cjk-enc.txt'. ---End of thaifont.txt---
