ofm2opl - convert Omega and TeX font-metric files to property-list files


ofm2opl [options] ofmname[.ofm] [oplfile[.opl]]


ofm2opl translates a binary Omega Font Metrics file, ofmname, into a human-readable property-list form. The program writes to standard output (by default) or to a file specified as oplfile.

The program also works with TeX TFM files, producing TeX PL files.


(Same as ovf2ovp).

output character codes according to type, either `hex', `octal' or `ascii'. Default is `hex'; `ascii' says to use ASCII for letters and digits, hex for all else.
output character codes according to stype, either `num' or `ascii'. Default is `num'; `ascii' as in -charcode-format. (These two redundant options both exist only for historical compatibility.)
output numbers according to ntype, either `hex' or `octal'; default is hex.
output coding scheme and family according to ttype, either `mixed' or `upper' case; default is mixed.

Email bug reports to <> (mailing list); good to check if the same bug is present in tftopl(1).

General discussion of Omega (and Aleph) can take place on the <> mailing list.

According to the WEB documentation:

The first TFtoPL program was designed by Leo Guibas in the summer of 1978. Contributions by Frank Liang, Doug Wyatt, and Lyle Ramshaw also had a significant effect on the evolution of the present code.

Extensions for an enhanced ligature mechanism were added by D.E. Knuth in 1989.

Extensions to handle extended font metric files (``OFM'') were added by John Plaice in December 1995 and January 1996, resulting in the new program OFM2OPL.

ofm2opl is based on the WEB source code for tftopl(1), although nowadays it is a link to omfonts, implemented entirely in C.

The primary authors of Omega were John Plaice and Yannis Haralambous. Omega (and Aleph) are now maintained as part of TeX Live.

This manual page was written by C.M. Connelly for the Debian GNU/Linux system. It is also now maintained as part of TeX Live.
