This is the file fdxfiles.txt of the CJK macro package ver. 4.8.5 (16-Oct-2021). Extended font definition files ============================== The CJK package modifies LaTeX's font loading mechanism to input an extended font definition file (with suffix `.fdx') immediately after a normal font definition file (with suffix `.fd') has been loaded. A `.fdx' file is optional. Here a list of useful commands---note that neither whitespace nor linebreaks produce output while macros are defined in such files, which is quite convenient. Immediately after selecting the proper subfont for a given input character, the CJK package tests whether a macro \////// is defined. If it exists, it is executed instead of calling \CJKsymbol. For halfwidth katakana, the macro is called \///// For fonts from HLaTeX the macro is called \////// For UTF-8, only characters in the range 0x800-0x10FFFF execute the test for this macro. , and are decimal numbers; is either `v' or `h'. The following commands are intended for `.fdx' files: o For vertical writing, \CJKvdef should be used to (globally) define the macros described above. It always prepends `//'. Example from c00bsmi.fdx: \CJKvdef{m/n/01/1}{\def\CJK@plane{v}\selectfont\CJKsymbol{4}} This defines macro `\C00/bsmi/m/n/01/1/v': If glyph 1 in subfont `01' (`bsmilp01' in this example) should be typeset, it is replaced with glyph 4 from subfont `v' (`bsmilpv'). \CJKhdef is the equivalent for horizontal writing. o Another macro is \CJKvlet, performing a global \let. Example (again from c00bsmi.fdx): \CJKvlet{bx/n/01/1}{m/n/01/1} This makes `\C00/bsmi/bx/n/01/1/v' the same as `\C00/bsmi/m/n/01/1/v'. \CJKhlet is the equivalent for horizontal writing. CJKvert.sty provides additional macros: o Glyphs which shouldn't be rotated are available with \CJKsymbolsimple. Here an example from c10gbsn.fdx: \CJKvdef{m/n/01/17}{\CJKsymbolsimple{17}} If glyph 17 in subfont `01' (`gbsnlp01') is requested, it is replaced with itself but unrotated. o Some correction parameters are available to position glyphs of a given font (i.e., all subfonts) while \CJKvert is active. \CJKvdef{norotate}{} The default of CJKvert.sty is to rotate all glyphs using the graphicx package. If `norotate' is present in a `.fdx' file, glyphs accessed with \CJKsymbol are not rotated. `fullheight', `height' and `offset' are used only if `norotate' is not set. \CJKvdef{fullheight}{} If defined, it sets the full height (height plus depth) of all CJK glyphs accessed with \CJKsymbol to . In most cases this value is 1em. \CJKvdef{height}{} If defined, it defines the height of all CJK glyphs accessed with \CJKsymbol. Consequently, the depth is set to `fullheight - height'. For example, the AFM file for `bsmilp01' gives 879 PS units for the `Ascender' value. Since 1em is 1000 PS units, a proper value for the `height' parameter is 0.88em. \CJKvdef{offset}{} If defined, shift the (rotated) glyphs accessed with \CJKsymbol vertically by . \CJKvdef{simpleoffset}{} If defined, shift all glyphs accessed with \CJKsymbolsimple vertically by . o The `offset' parameter is available to position glyphs of a given font (i.e., all subfonts) while \CJKhorz is active. \CJKhdef{offset}{} If defined (and \CJKhorz being active), shift the glyphs accessed with \CJKsymbol vertically by . ---End of fdxfiles.txt---
