23 * PSDRV_AFM2C(AFM *afm) writes the AFM data structure addressed by afm (and
24 * its subsidiary objects) as a C file which can which can then be built in to
25 * the driver. It creates the file in the current directory with a name of
26 * the form {FontName}.c, where {FontName} is the PostScript font name with
27 * hyphens replaced by underscores.
29 * To use this function, do the following:
31 * * Edit dlls/wineps/Makefile (or dlls/wineps/Makefile.in) and add
32 * afm2c.c as a source file.
34 * * Edit dlls/wineps/afm.c and uncomment the call to PSDRV_AFM2C in
35 * PSDRV_DumpFontList() (or wherever it gets moved). The resulting
36 * compiler warning can be safely ignored.
38 * IMPORTANT: For this to work, all glyph names in the AFM data being
39 * written *MUST* already be present in PSDRV_AGLGlyphNames in agl.c.
40 * See mkagl.c in this directory for information on how to generate
41 * updated glyph name information. Note, however, that if the glyph
42 * name information in agl.c is regenerated, *ALL* AFM data must also
