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 <stdio.h> - -/* 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.
