Making outline fonts from METAFONT#
TeXtrace, originally developed by Péter Szabó, is a bundle of Unix scripts that use Martin Weber’s freeware boundary tracing package autotrace to generate Type 1 outline fonts from METAFONT bitmap font outputs. The result is unlikely ever to be of the quality of the commercially-produced Type 1 font, but there’s always the FontForge font editor to tidy things. Whatever, there remain fonts which many people find useful and which fail to attract the paid experts, and auto-tracing is providing a useful service here. Notable sets of fonts generated using
TeXtrace are Péter Szabó’s own EC/TC font set
tt2001 and Vladimir Volovich’s CM-Super set, which covers the EC, TC, and the Cyrillic LH font sets (for details of both of which sets, see « 8-bit type 1 fonts).
Another system, which arrived slightly later, is mftrace : this is a small Python program that does the same job.
Mftrace may use either
TeXtrace) or Peter Selinger’s potrace to produce the initial outlines to process.
Mftrace is said to be more flexible, and easier to use, than is
TeXtrace, but both systems are increasingly being used to provide Type 1 fonts to the public domain.
MetaType1 system aims to use METAFONT font sources, by way of MetaPost and a bunch of scripts and so on, to produce high-quality Type 1 fonts. The first results, the Latin Modern fonts, are now well-established, and a bunch of existing designs have been reworked in MetaType1 format.
