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. * */ #include <string.h> #include <stdio.h> #include <math.h> #include "wine/debug.h" #include "psdrv.h" WINE_DEFAULT_DEBUG_CHANNEL(psdrv); inline static void cursorto(FILE *of, int np, int cp) { int ntp = np & 0xfffffff8; int ctp = cp & 0xfffffff8; while (ctp < ntp) { fputc('\t', of); ctp += 8; cp = ctp; } while (cp < np) { fputc(' ', of); ++cp; } } static void writeHeader(FILE *of, const AFM *afm, const char *buffer) { int i; fputc('/', of); for (i = 1; i < 80; ++i) fputc('*', of); fprintf(of, "\n" " *\n" " *\tFont metric data for %s\n" " *\n" " *\tCopyright 2001 Ian Pilcher\n" " *\n" " *\n" " *\tSee dlls/wineps/data/COPYRIGHTS for font copyright " "information.\n" " *\n" " */\n" "\n" "#include \"psdrv.h\"\n" "#include \"data/agl.h\"\n", afm->FullName); } static void writeMetrics(FILE *of, const AFM *afm, const char *buffer) { int i; fputs("\n\n/*\n * Glyph metrics\n */\n\n", of); fprintf(of, "static const AFMMETRICS metrics[%i] =\n{\n", afm->NumofMetrics); for (i = 0; i < afm->NumofMetrics - 1; ++i) { fprintf(of, " { %3i, 0x%.4lx, %4g, GN_%s },\n", afm->Metrics[i].C, afm->Metrics[i].UV, afm->Metrics[i].WX, afm->Metrics[i].N->sz); } fprintf(of, " { %3i, 0x%.4lx, %4g, GN_%s }\n};\n", afm->Metrics[i].C, afm->Metrics[i].UV, afm->Metrics[i].WX, afm->Metrics[i].N->sz); } static void writeAFM(FILE *of, const AFM *afm, const char *buffer) { fputs("\n\n/*\n * Font metrics\n */\n\n", of); fprintf(of, "const AFM PSDRV_%s =\n{\n", buffer); cursorto(of, 44, fprintf(of, " \"%s\",", afm->FontName)); fputs("/* FontName */\n", of); cursorto(of, 44, fprintf(of, " \"%s\",", afm->FullName)); fputs("/* FullName */\n", of); cursorto(of, 44, fprintf(of, " \"%s\",", afm->FamilyName)); fputs("/* FamilyName */\n", of); cursorto(of, 44, fprintf(of, " \"%s\",", afm->EncodingScheme)); fputs("/* EncodingScheme */\n", of); cursorto(of, 44, fprintf(of, " %s,", (afm->Weight > 550) ?
