* *
* Title: pfm2afm - Convert Windows .pfm files to .afm files *
* *
* Author: Ken Borgendale 10/9/91 Version 1.0 *
* *
* Function: *
* Convert a Windows .pfm (Printer Font Metrics) file to a *
* .afm (Adobe Font Metrics) file. The purpose of this is *
* to allow fonts put out for Windows to be used with OS/2. *
* *
* Syntax: *
* pfm2afm infile [outfile] -a *
* *
* Copyright: *
* pfm2afm - Copyright (C) IBM Corp., 1991 *
* *
* This code is released for public use as long as the *
* copyright remains intact. This code is provided asis *
* without any warrenties, express or implied. *
* *
* Notes: *
* 1. Much of the information in the original .afm file is *
* lost when the .pfm file is created, and thus cannot be *
* reconstructed by this utility. This is especially true *
* of data for characters not in the Windows character set. *
* *
* 2. This module is coded to be compiled by the MSC 6.0. *
* For other compilers, be careful of the packing of the *
* PFM structure. *
* *

* *
* Modifications by Rod Smith, 5/22/96 *
* *
* These changes look for the strings "italic", "bold", "black", *
* and "light" in the font's name and set the weight accordingly *
* and adds an ItalicAngle line with a value of "0" or "-12.00". *
* This allows OS/2 programs such as DeScribe to handle the bold *
* and italic attributes appropriately, which was not the case *
* when I used the original version on fonts from the KeyFonts *
* Pro 2002 font CD. *
* *
* I've also increased the size of the buffer used to load the *
* .PFM file; the old size was inadequate for most of the fonts *
* from the SoftKey collection. *
* *
* Compiled with Watcom C 10.6 *
* *
********************************************************************/
/********************************************************************
* *
* Further modifications, 4/21/98, by Rod Smith *
* *
* Minor changes to get the program to compile with gcc under *
* Linux (Red Hat 5.0, to be precise). I had to add an itoa *
* function from the net (the function was buggy, so I had to fix *
* it, too!). I also made the program more friendly towards *
* files with mixed-case filenames. *
* *
********************************************************************/
/********************************************************************
* *
* 1/31/2005, by Paulo Soares *
* *
* This code was integrated into iText. *
* Note that the itoa function mentioned in the comment by Rod *
* Smith is no longer in the code because Java has native support *
* in PrintWriter to convert integers to strings *
