DOCUMENTATION FOR HMP2HFN.PL
hmp2hfn.pl reads one or more hmp files and one or more font files in
either the original Hershey format or in the HFN format and writes to
the output a file in the HFN format, outputting only those symbols that
are listed in the hmp files.
The advantage of doing this filtering process, is that when the
characters are loaded from disk, only characters that are needed are
allocated into memory, which results in a significant memory saving.
The syntax to run hmp2hfn.pl is
perl hmp2hfn.pl hmpfile1.hmp [hmpfile2.hmp ...] fontfile1 > outfile.hfn
Example:
Create an hfn file of only gothic characters:
perl hmp2hfn.pl gothgbt.hmp gothgrt.hmp hersh.oc* > gothic.hfn
