{Towards an operational \AllTeX\ package supporting optical scaling 
 of dynamic mathematical symbols}
{Abdelouahad Bayar}
{In processing of digital documents containing mathematical formulas,
the handling of dynamic mathematical symbols is still a significant and
difficult problem. In fact, a tool to compose mathematics must support
the typing of variable-sized symbols taking care of optical scaling and
reaching the quality of metal typesetting. Until now, no tool
provides these possibilities in a direct and operational way. This
contribution highlights and puts into practice the basic steps to
develop a \AllTeX\ package directly based on a parameterized Type~3
PostScript font. This package will provide to \AllTeX\ end-users a tool
to compute in the usual way mathematical formulas consisting of dynamic
mathematical symbols and taking into account optical scaling

Formatting \AllTeX\ documents using this package is achieved without
requiring special environments or external programs. The concept of
using parameterized Type~3 fonts directly with \AllTeX\ commands can
yield an accurate and straightforward way to manage dynamic graphics in
documents formatted under \AllTeX, including logo graphics, for example.

Keywords: \AllTeX, PostScript Type~3, dynamic mathematical symbols,
optical scaling.
