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 + + \<encoding>/<family>/<series>/<shape>/<plane>/<code>/<direction> + +is defined. If it exists, it is executed instead of calling \CJKsymbol. + +For halfwidth katakana, the macro is called + + \<encoding>/<family>/<series>/<shape>/<code>/<direction> + +For fonts from HLaTeX the macro is called + + \<encoding>/<family>/<series>/<shape>/<byte1>/<byte2>/<direction> + +For UTF-8, only characters in the range 0x800-0x10FFFF execute the test for +this macro. + +<code>, <byte1> and <byte2> are decimal numbers; <direction> 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 `<encoding>/<family>/'. + 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}{<dimension>} + + If defined, it sets the full height (height plus depth) of all CJK + glyphs accessed with \CJKsymbol to <dimension>. In most cases this + value is 1em. + + \CJKvdef{height}{<dimension>} + + 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}{<dimension>} + + If defined, shift the (rotated) glyphs accessed with \CJKsymbol + vertically by <dimension>. + + \CJKvdef{simpleoffset}{<dimension>} + + If defined, shift all glyphs accessed with \CJKsymbolsimple vertically + by <dimension>. + +o The `offset' parameter is available to position glyphs of a given + font (i.e., all subfonts) while \CJKhorz is active. + + \CJKhdef{offset}{<dimension>} + + If defined (and \CJKhorz being active), shift the glyphs accessed + with \CJKsymbol vertically by <dimension>. + +---End of fdxfiles.txt--- |
