The program can be used as is by making a procedure call to + * parse an AFM file and have the data stored, or an application developer + * may wish to customize the code. + * + * This header file defines the data structures used as well as the key + * strings that are currently recognized by this version of the AFM parser. + * This program is based on the document "Adobe Font Metrics Files, + * Specification Version 2.0". + * + * AFM files are separated into distinct sections of different data. Because + * of this, the parseAFM program can parse a specified file to only save + * certain sections of information based on the application's needs. A record + * containing the requested information will be returned to the application. + * + * AFM files are divided into five sections of data: + * 1) The Global Font Information + * 2) The Character Metrics Information + * 3) The Track Kerning Data + * 4) The Pair-Wise Kerning Data + * 5) The Composite Character Data + * + * Basically, the application can request any of these sections independent + * of what other sections are requested. In addition, in recognizing that + * many applications will want ONLY the x-width of characters and not all + * of the other character metrics information, there is a way to receive + * only the width information so as not to pay the storage cost for the + * unwanted data. An application should never request both the + * "quick and dirty" char metrics (widths only) and the Character Metrics + * Information since the Character Metrics Information will contain all + * of the character widths as well. + * + * There is a procedure in parseAFM.c, called parseFile, that can be + * called from any application wishing to get information from the AFM File. + * This procedure expects 3 parameters: a vaild file descriptor, a pointer + * to a (FontInfo *) variable (for which space will be allocated and then + * will be filled in with the data requested), and a mask specifying + * which data from the AFM File should be saved in the FontInfo structure. + * + * The flags that can be used to set the appropriate mask are defined below. + * In addition, several commonly used masks have already been defined. + * + * History: + * original: DSM Thu Oct 20 17:39:59 PDT 1988 + * modified: DSM Mon Jul 3 14:17:50 PDT 1989 + * - added 'storageProblem' return code + * - fixed typos + */ +#ifndef _MDVI_PARSEAFM_H +#define _MDVI_PARSEAFM_H 1 + +#include "sysdeps.h" + +#include + +/* your basic constants */ +#define TRUE 1 +#define FALSE 0 +#define EOL '\n' /* end-of-line indicator */ +#define MAX_NAME 4096 /* max length for identifiers */ +#define BOOL int +#define FLAGS int + +/* Flags that can be AND'ed together to specify exactly what + * information from the AFM file should be saved. */ +#define P_G 0x01 /* 0000 0001 */ /* Global Font Info */ +#define P_W 0x02 /* 0000 0010 */ /* Character Widths ONLY */ +#define P_M 0x06 /* 0000 0110 */ /* All Char Metric Info */ +#define P_P 0x08 /* 0000 1000 */ /* Pair Kerning Info */ +#define P_T 0x10 /* 0001 0000 */ /* Track Kerning Info */ +#define P_C 0x20 /* 0010 0000 */ /* Composite Char Info */ + +/* Commonly used flags */ +#define P_GW (P_G | P_W) +#define P_GM (P_G | P_M) +#define P_GMP (P_G | P_M | P_P) +#define P_GMK (P_G | P_M | P_P | P_T) +#define P_ALL (P_G | P_M | P_P | P_T | P_C) + +/* Possible return codes from the parseFile procedure. + * + * ok means there were no problems parsing the file. + * + * parseError means that there was some kind of parsing error, but the + * parser went on.

The first + * MAX_CLASS-1 ones correspond to `real' fonts (pk, gf, vf, type1, truetype, + * etc). The last one corresponds to `metric' fonts that are used as a last + * resort (tfm, afm, ofm, ...). When a font is looked up, it is tried in a + * `high' priority class (0 being the highest priority). The priority is + * lowered until it reaches MAX_CLASS-1. Then the whole thing is repeated + * for the fallback font. When the search reaches MAX_CLASS-1, we lookup the + * original font, and then the fallback font. The search can be done + * incrementally, with several calls to mdvi_lookup_font(). If this function + * is called again to continue a search, the function assumes the previous + * font it returned was not valid, and it goes on to the next step. + * + * Reason for this: + * Some font types are quite expensive to load (e.g. Type1), so loading + * them is deferred until the last possible moment. This means that a font that + * was supposed to exist may have to be discarded. Until now, MDVI had no ability to + * "resume" a search, so in this case it would have produced an error, regardless + * of whether the offending font existed in other formats. + * Also, given the large number of font types supported by MDVI, some mechanism + * was necessary to bring some order into the chaos. + * + * This mechanism fixes these two problems. For the first one, a search can + * be "resumed" and all the font formats tried for the missing font, and + * again for the fallback font (see above). As for the second, the + * hierarchical division in classes gives a lot of flexibility in how the + * fonts are configured. + */ + +#include "mdvi.h" + +#define HAVE_PROTOTYPES 1 +#include +#include + +struct _DviFontClass { + DviFontClass *next; + DviFontClass *prev; + DviFontInfo info; + int links; + int id; +}; + +char *_mdvi_fallback_font = MDVI_FALLBACK_FONT; + +/* this leaves classes 0 and 1 for `real' fonts */ +#define MAX_CLASS 3 +static ListHead font_classes[MAX_CLASS]; +static int initialized = 0; + +static void init_font_classes(void) +{ + int i; + + for(i = 0; i < MAX_CLASS; i++) + listh_init(&font_classes[i]); + initialized = 1; +} + +int mdvi_get_font_classes(void) +{ + return (MAX_CLASS - 2); +} + +char **mdvi_list_font_class(int klass) +{ + char **list; + int i, n; + DviFontClass *fc; + + if(klass == -1) + klass = MAX_CLASS-1; + if(klass < 0 || klass >= MAX_CLASS) + return NULL; + n = font_classes[klass].count; + list = xnalloc(char *, n + 1); + fc = (DviFontClass *)font_classes[klass].head; + for(i = 0; i < n; fc = fc->next, i++) { + list[i] = xstrdup(fc->info.name); + } + list[i] = NULL; + return list; +} + +int mdvi_register_font_type(DviFontInfo *info, int klass) +{ + DviFontClass *fc; + + if(klass == -1) + klass = MAX_CLASS-1; + if(klass < 0 || klass >= MAX_CLASS) + return -1; + if(!initialized) + init_font_classes(); + fc = xalloc(struct _DviFontClass); + fc->links = 0; + fc->id = klass; + fc->info.name = xstrdup(info->name); + fc->info.scalable = info->scalable; + fc->info.load = info->load; + fc->info.getglyph = info->getglyph; + fc->info.shrink0 = info->shrink0; + fc->info.shrink1 = info->shrink1; + fc->info.freedata = info->freedata; + fc->info.reset = info->reset; + fc->info.lookup = info->lookup; + fc->info.kpse_type = info->kpse_type; + listh_append(&font_classes[klass], LIST(fc)); + return 0; +} + +int mdvi_unregister_font_type(const char *name, int klass) +{ + DviFontClass *fc; + int k; + + if(klass == -1) + klass = MAX_CLASS - 1; + + if(klass >= 0 && klass < MAX_CLASS) { + k = klass; + LIST_FOREACH(fc, DviFontClass, &font_classes[k]) { + if(STREQ(fc->info.name, name)) + break; + } + } else if(klass < 0) { + for(k = 0; k < MAX_CLASS; k++) { + LIST_FOREACH(fc, DviFontClass, &font_classes[k]) { + if(STREQ(fc->info.name, name)) + break; + } + if(fc) break; + } + } else + return -1; + + if(fc == NULL || fc->links) + return -1; + /* remove it */ + listh_remove(&font_classes[k], LIST(fc)); + + /* and destroy it */ + xfree(fc->info.name); + xfree(fc); + return 0; +} + +static char *lookup_font(DviFontClass *ptr, const char *name, Ushort *h, Ushort *v) +{ + char *filename; + + /* + * If the font type registered a function to do the lookup, use that. + * Otherwise we use kpathsea. + */ + if(ptr->info.lookup) + filename = ptr->info.lookup(name, h, v); + else if(ptr->info.kpse_type <= kpse_any_glyph_format) { + kpse_glyph_file_type type; + + filename = kpse_find_glyph(name, Max(*h, *v), + ptr->info.kpse_type, &type); + /* if kpathsea returned a fallback font, reject it */ + if(filename && type.source == kpse_glyph_source_fallback) { + xfree(filename); + filename = NULL; + } else if(filename) + *h = *v = type.dpi; + } else + filename = kpse_find_file(name, ptr->info.kpse_type, 1); + return filename; +} + +/* + * Class MAX_CLASS-1 is special: it consists of `metric' fonts that should + * be tried as a last resort + */ +char *mdvi_lookup_font(DviFontSearch *search) +{ + int kid; + int k; + DviFontClass *ptr; + DviFontClass *last; + char *filename = NULL; + const char *name; + Ushort hdpi, vdpi; + + if(search->id < 0) + return NULL; + + if(search->curr == NULL) { + /* this is the initial search */ + name = search->wanted_name; + hdpi = search->hdpi; + vdpi = search->vdpi; + kid = 0; + last = NULL; + } else { + name = search->actual_name; + hdpi = search->actual_hdpi; + vdpi = search->actual_vdpi; + kid = search->id; + last = search->curr; + } + + ptr = NULL; +again: + /* try all classes except MAX_CLASS-1 */ + for(k = kid; !filename && k < MAX_CLASS-1; k++) { + if(last == NULL) + ptr = (DviFontClass *)font_classes[k].head; + else + ptr = last->next; + while(ptr) { + DEBUG((DBG_FONTS, "%d: trying `%s' at (%d,%d)dpi as `%s'\n", + k, name, hdpi, vdpi, ptr->info.name)); + /* lookup the font in this class */ + filename = lookup_font(ptr, name, &hdpi, &vdpi); + if(filename) + break; + ptr = ptr->next; + } + last = NULL; + } + if(filename != NULL) { + search->id = k-1; + search->curr = ptr; + search->actual_name = name; + search->actual_hdpi = hdpi; + search->actual_vdpi = vdpi; + search->info = &ptr->info; + ptr->links++; + return filename; + } + + if(kid < MAX_CLASS - 1 && !STREQ(name, _mdvi_fallback_font)) { + warning("font `%s' at %dx%d not found, trying `%s' instead\n", + name, hdpi, vdpi, _mdvi_fallback_font); + name = _mdvi_fallback_font; + kid = 0; + goto again; + } + + /* we tried the fallback font, and all the `real' classes.
