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