Compacting Oriental Fonts by Optimizing Parametric Elements
Ideographic oriental fonts have an order of magnitude more symbols in their
alphabet and are more complex in their design. Their unique characteristic of
composing glyphs from radicals and radicals from strokes can help simplify their
digital representation. We present a method to compact existing outline based
oriental fonts with the ability to preserve their original design, by using a
parametric representation for element based glyphs. Our method comprises of four
main stages: classification of elements to groups, parametrization of
representative elements, optimization of the parametric representatives to match
all group elements, and compaction using quantization. Our method introduces
automatic classification and optimization using topological signature mapping
between element shapes. It also features simple and natural control over the
tradeoff between compacting and preserving quality by using quantization in
parametric space.
