The package provides a LaTeX interface to the micro-typographic
|
|
extensions that were introduced by pdfTeX and have since also
|
|
propagated to XeTeX and LuaTeX: most prominently, character
|
|
protrusion and font expansion, furthermore the adjustment of
|
|
interword spacing and additional kerning, as well as
|
|
hyphenatable letterspacing (tracking) and the possibility to
|
|
disable all or selected ligatures. These features may be
|
|
applied to customisable sets of fonts, and all
|
|
micro-typographic aspects of the fonts can be configured in a
|
|
straight-forward and flexible way. Settings for various fonts
|
|
are provided. Note that character protrusion requires pdfTeX,
|
|
LuaTeX, or XeTeX. Font expansion works with pdfTeX or LuaTeX.
|
|
The package will by default enable protrusion and expansion if
|
|
they can safely be assumed to work. Disabling ligatures
|
|
requires pdfTeX or LuaTeX, while the adjustment of interword
|
|
spacing and of kerning only works with pdfTeX. Letterspacing is
|
|
available with pdfTeX or LuaTeX. The alternative package
|
|
'letterspace', which also works with plain TeX, provides the
|
|
user commands for letterspacing only, omitting support for all
|
|
other extensions.
