The microtypographic +extensions (protrusions, expansions) of all fonts are available after +\^`\enablemte`. The \LaTeX/ package Microtype does similar effect. + +The \^`\enablemte` macro reloads the current font with microtypographic +extensions (mte) enabled and all new fonts loaded by the Font Selection System have +mte enabled too, because they are added to the +\olink[_fontfeatures]{\_fontfeatures} macro used by \OpTeX/. + +The \^`\enablemte` macro does only local settings. If it is used in a group then +only fonts used in this group have mte. + +The \^`\enablemte` macro sets (among other things) +\elink[pdfprotrudechars]{\protrudechars}`=2` (protrusion is enabled) and +\elink[pdfadjustspacing]{\adjustspacing}`=2` (font expansion is enabled). +You can disable these features by setting these primitive registers to zero +value (it is default if \^`\enablemte` is not used). +Note, that the values of these registers are checked when +paragraph is finalized although the fonts were loaded with mte enabled. +It means that you have to use `\par` before end of group +if you use \^`\enablemte` inside a group. +For example: + +\begtt +{\enablemte + Roman font with mte enabled, \it italic font with mte enabled. + \par % mte features are used +} +\endtt +% +Or, simply use \^`\enablemte` at beginning of your document. + +On the other hand, you can use \^`\disablemte` macro which reloads current +font with mte disabled and all newly loaded fonts have +mte disabled too. The macro has local validity. For example, +`{\disablemte text}` prints `text` by a font with +mte disabled. It works locally in the middle of the paragraph (unlike setting +`\protrudechars` and `\adjustspacing` to zero). + +You can define your own protrusion or expansion values: copy macros +`\_mte_AlphabetPR`, `\_mte_quotPR`, etc.\ from this package and define them +as you wish using `\def`. Such definition has precedence. +Similar definitions can be in some font family files too, so: do your +definition after all `\fontfam` if you want to keep the precedence. +All such definitions must be performed before the `\mteinit` command. + +You can use `\def\_mte_P` for data of protrusion for all fonts +which has general precedence. For example, if you want to protrude hyphen +char with factor one at the right side and by factor 0.5 at the left side, use +\begtt +\def\_mte_P {% user specification, Protrusion, Regular fonts + \_mte - = {.5, 1}, % /hyphen +} +\endtt +Analogical macro can be used for expansion data `\_mte_X`. + +You can use \^`\setfpfactor` `<factor><space>` to set the factor by which +all protrusion data are scaled. The <factor> is decimal number and its default +value is~1. This macro can be used before \^`\enablemte`. +You can use \^`\setfxfactor` `<factor><space>` with analogical meaning, +expansion data are scaled by given~<factor>. + +If you feel that default microtypographic data are wrong in a particular case, +please let me know.
