<h2><a name="About"></a>About Ghostscript fonts</h2>

<p>
Ghostscript is distributed with two kinds of files related to fonts:

<ul>
<li>the fonts themselves in individual files, and
<li>a file "<code>Fontmap</code>" that defines for
Ghostscript which file represents which font.
</ul>

<p>
Additionally, a file <code>cidfmap</code> can be used
to create CID fonts for CJK font files on the system See
the section on <a href="Use.htm#CIDFontSubstitution">CID Font Substitution</a>
for details.

<p>
Most of the font files supplied with Ghostscript have the extension
<code>.pfb</code>, and a few have <tt><b>.pfa</b></tt> or
<code>.gsf</code>.  Each file defines one ordinary PostScript Type 1
outline font which any PostScript language interpreter can use.  Files with
<code>.pfa</code> or <tt><b>.pfb</b></tt> extensions are also compatible
with Adobe Type Manager (ATM) and with tools that don't include a full
PostScript language interpreter; files with <code>.gsf</code> extension
are incompatible with ATM and other tools. Ghostscript compiled with the
"ttfont" option can also use TrueType fonts with the extension
<code>.ttf</code>.

<p><a name="Fontmap"></a>
When Ghostscript needs a font, it must have some way to know where to look
for it: that's the purpose of the <code>Fontmap</code> file, which
associates the names of <em>fonts</em> such as <code>/Times-Roman</code>
with the names of font <em>files</em>, such as
<code>n021003l.pfb</code>.  <code>Fontmap</code> can also create
aliases for font names, so that for instance,
<code>/NimbusNo9L-Regu</code> means the same font as
<code>/Times-Roman</code>.

<hr>

<h2><a name="Free_fonts"></a>Ghostscript's free fonts</h2>

<p>
Two sets of free fonts are supplied for Ghostscript:

<ul>
<li>35 commercial-quality Type 1 basic PostScript fonts -- Times,
Helvetica, Courier, Symbol, etc. -- contributed by URW++ Design and
Development Incorporated, of Hamburg, Germany
(<a href="http://www.urwpp.de/">http://www.urwpp.de/</a>).  Fontmap names
them all.

<li>A miscellaneous set including Cyrillic, kana, and fonts derived from
the free Hershey fonts, with improvements (such as adding accented
characters) by Thomas Wolff.  The Hershey-based fonts are quite different
from traditional printer or display fonts; you can read about them in more
detail in the <a href="Hershey.htm">documentation on Hershey fonts</a>.

</ul>

<h2><a name="Other_fonts"></a>Other free fonts</h2>

<h3><a name="Computer_Modern"></a>Computer Modern Fontmap</h3>

<p>
Don Knuth's Computer Modern fonts are popular, free, and widely available.
A Fontmap appropriate for these fonts is available from:

<blockquote>
<a
href="ftp://tug.ctan.org/tex-archive/fonts/cm/ps-type1/contrib/Fontmap.cmr" 
class="offsite">
ftp://tug.ctan.org/tex-archive/fonts/cm/ps-type1/contrib/Fontmap.cmr</a>
</blockquote>

<p>
or from other <a href="http://www.ctan.org/" class="offsite">CTAN</a> sites.

<h3><a name="Chinese"></a>Free Chinese (Hanzi) fonts</h3>

<p>
A free Chinese font, originally provided by courtesy of Jackson Technology,
Ltd., Taiwan under the GPL and now distributed by the Taiwan NeXT User
Group, is available from:

<blockquote>
<a href="ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/3rdparty/fonts/hanzi/" 
class="offsite">ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/3rdparty/fonts/hanzi/</a>
</blockquote>

<p>
Prof. Wu of the Department of Economics of National Taiwan University has
created several free Type 1 Chinese fonts designed to be used with TeX.  His
e-mail is <a
href="mailto:ntut019@ccms.ntu.edu.tw">ntut019@ccms.ntu.edu.tw</a>.  The
fonts are available from

<blockquote>
<a href="ftp://cle.linux.org.tw/pub/fonts/cwfont/" 
class="offsite">ftp://cle.linux.org.tw/pub/fonts/cwfont/</a><br>
</blockquote>

<p>
Arphic Technology Co., Ltd., has made several free TrueType Chinese fonts
available under the Arphic Public License, a license very similar to the
GPL.  (Ghostscript can use TrueType fonts if Ghostscript is compiled with
the <code>ttfont</code> feature included: see <a
href="Make.htm#Features_and_devices">here</a> for more information.)  The
fonts and license are available from

<blockquote>
<a href="ftp://cle.linux.org.tw/pub/fonts/arphic/" 
class="offsite">ftp://cle.linux.org.tw/pub/fonts/arphic/</a><br>
</blockquote>

<h3><a name="Japanese"></a>Free Japanese (Kanji) fonts</h3>

<p>
Mr. Tetsurou Tanaka of the Department of Engineering, University of Tokyo,
has created a set of free Kanji fonts available from

<blockquote>
<a href="ftp://ftp.ipl.t.u-tokyo.ac.jp/Font/" 
class="offsite">ftp://ftp.ipl.t.u-tokyo.ac.jp/Font/</a><br>
</blockquote>

<p>
along with documentation in Japanese and English describing their
conditions of use and how to use them.  An older copy of these fonts, under
somewhat different names, is available at the Ghostscript site:

<blockquote>
<a href="ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/3rdparty/fonts/kanji/">
ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/3rdparty/fonts/kanji/</a><br>
</blockquote>

<p>
Mr. Norio Katayama has done some work to make Ghostscript work well with
Kanji fonts.  An easy-to-install Kanji font for Ghostscript, with
installation instructions, is at

<blockquote>
<a href="http://www.cit.ics.saitama-u.ac.jp/~far/howto/gs-ttf.html" 
class="offsite">http://www.cit.ics.saitama-u.ac.jp/~far/howto/gs-ttf.html</a>
</blockquote>

<p>
The same site has patches to make Ghostscript work with Japanese VF fonts,
with documentation in both English and Japanese:

class="offsite">http://www.cit.ics.saitama-u.ac.jp/~far/howto/gs-vflib.html</a>
</blockquote>

<p>
Here are some other resources in Japanese relating to VFlib and using
Ghostscript with Japanese fonts:

<h3><a name="Cyrillic"></a>Free Cyrillic fonts</h3>

<p>
N. Glonty and A. Samarin created in 1989 a Cyrillic extension of TeX's
"Computer Modern" fonts, now freely available through the
<a href="http://www.ctan.org/" class="offsite">Comprehensive TeX Archive Network</a> (CTAN),
for instance at

<blockquote>
<a href="ftp://ctan.tug.org/tex-archive/fonts/cyrillic/cmcyr/" 
class="offsite">ftp://ctan.tug.org/tex-archive/fonts/cyrillic/cmcyr/</a>
</blockquote>

<p>
<a href="http://www.ctan.org/" class="offsite">CTAN's</a> entire collection of Cyrillic fonts
is, for instance, at

<blockquote>
<a href="ftp://ctan.tug.org/tex-archive/fonts/cyrillic/" 
class="offsite">ftp://ctan.tug.org/tex-archive/fonts/cyrillic/</a>
</blockquote>

<p>
Basil K. Malyshev created the "Paradissa Fonts Collection" in 1993.  It
contained 165 fonts, including the Glonty and Samarin font above plus other
Computer Modern, Euler, and LaTeX fonts, all in PostScript Type 1 format
with <code>.afm</code> and <code>.pfm</code> files, compatible with ATM.
The collection could once be found through CTAN, for instance at

<blockquote>
http://www.ctan.org/tex-archive/fonts/
<!-- orginal was ftp://ctan.tug.org/tex-archive/fonts/postscript/cm/ -->
</blockquote>

<p>
but the collection no longer seems to be available. However, the
<a href="http://www.ctan.org/tex-archive/fonts/" class="offsite">ctan fonts directory</a>
remains an excellent source of free fonts, many of which are offered in
postscript as well we as TeX Metafont format.

<h3><a name="Partial_Unicode_fonts"></a>(Partial) Unicode fonts</h3>

<p>
George W. Wilson is distributing some free partial Unicode fonts he created.
These fonts currently lack Arabic and CJK characters, but they include a
very large subset of the remaining Unicode set.  They are available in both
Type 1 and TrueType formats.  See

<h2><a name="Get_fonts"></a>How Ghostscript gets fonts when it runs</h2>

<p>
Fonts occupy about 50KB each, so Ghostscript doesn't load them all
automatically when it runs.  Instead, as part of normal initialization
Ghostscript runs a file <code>gs_fonts.ps</code>, which arranges to load
fonts on demand using information from the font map.  To preload all of the
known fonts, invoke the procedure

<blockquote><code>
loadallfonts
</code></blockquote>

<p>
The file <code>prfont.ps</code> contains code to print a sample page of
a font.  Load this program by including it in the <code>gs</code>
command line or by invoking

<blockquote><code>
(prfont.ps) run
</code></blockquote>

<p>
Then to produce a sampler of a particular font XYZ, invoke

<blockquote><code>
/XYZ DoFont
</code></blockquote>

<p>For example,

<blockquote><code>
/Times-Roman DoFont
</code></blockquote>

<p>
For more information about how Ghostscript loads fonts during execution,
see <a href="Use.htm#Font_lookup">here</a>.

<hr>

<h2><a name="Platform_fonts"></a>Platform fonts</h2>

<p>
Ghostscript displays text on screen using whatever font technology is
provided by the system on which it runs, by calling the system's API to
display text.  On platforms with X Windows, this is X Windows; on MS
Windows it may be TrueType or ATM; Ghostscript neither knows nor cares.

<p>
The PostScript language specifies that fonts are data structures with
particular contents (for instance, they include a bounding box for the
font, an Encoding vector to specify the character set, etc.), and it is
common for PostScript files to use this fact; also, characters can be used
as clipping regions, and can be arbitrarily algorithmically rotated,
skewed, expanded or condensed, etc. Most of this information is available
in some form from the underlying graphics system, but one crucial piece is
not: the actual scalable outlines of the characters, which Ghostscript
needs in order to implement both clipping with character shapes and
arbitrarily transformed characters.  Consequently

<blockquote>
Ghostscript needs the scalable outlines of any font mentioned in a
document, and loads them from the disk (<code>.pfa</code>,
<code>.pfb</code>, or <tt><b>.gsf</b></tt>
file) in the usual way, even if it uses the platform's font machinery to
display the characters. In other words, Ghostscript must still be able to
find its font files.
</blockquote>

<p>
To make matters worse, platforms use different names for their standard
fonts.  For example, the Times Roman font, for which PostScript files use
the name "<code>Times-Roman</code>", may be known as
"<code>Times-Roman</code>", "<b><tt>Times&nbsp;Roman</tt></b>",
"<code>Tms&nbsp;Rmn</code>",
"<code>Times&nbsp;New&nbsp;Roman</code>", or
"<code>TimesNewRoman</code>".  The name may even be completely
different: the usual Helvetica-equivalent TrueType font is called
"<code>Arial</code>".  It is possible to deal with this situation by
introducing aliases in Fontmap, but there are two reasons why Ghostscript
does not currently do this:

<ol>
<li>Methods of naming in different systems are so unstandardized that there
seems to be no small set of alternative names likely to cover most
situations.  All five of the names above for Times Roman have been seen
under Windows and OS/2, depending on the version of the system, whether it
uses TrueType or ATM, and other unknown factors.

<li>Each alias takes up space at run time.  If each of the standard fonts
has three additional aliases, this might amount to 50KB of wasted space,
which may be a lot on some smaller systems.
</ol>

<p>
If you don't seem to be getting nice characters on the screen under MS
Windows, you can try adding aliases to Fontmap, according to the
documentation you'll find in there.

<hr>

<h2><a name="Add_fonts"></a>Adding your own fonts</h2>

<p>
Ghostscript can use any Type 0, 1, 3, 4, or 42 font acceptable to
other PostScript language interpreters or to ATM, including MultiMaster
fonts.  Beginning with release 4.0, Ghostscript can also use TrueType fonts
if it was compiled with the "ttfont" option.

<p>
To add fonts of your own, you must edit Fontmap to include at the end an
entry for your new font; the format for entries is documented
in Fontmap itself.  Since later entries in Fontmap override earlier
entries, a font you add at the end supersedes any corresponding fonts supplied
with Ghostscript and defined earlier in the file.

<p>
In the PC world, Type 1 fonts are customarily given names ending in
<code>.PFA</code> or <tt><b>.PFB</b></tt>.  Ghostscript can use these
directly: you just need to make the entry in Fontmap.  If you want to use
with Ghostscript a commercial Type 1 font (such as fonts obtained in
conjunction with Adobe Type Manager), please read carefully the license that
accompanies the font to satisfy yourself that you may do so legally; we take
no responsibility for any possible violations of such licenses.  The same
applies to TrueType fonts.

<h3><a name="Convert_BDF"></a>Converting BDF fonts</h3>

<p>
Ghostscript provides a way to construct a (low-quality) Type 1 font from a
bitmap font in the BDF format popular in the Unix world.  The shell script
<code>bdftops</code> (Unix) or the command file
<code>bdftops.bat</code> (DOS) converts a BDF file to a
scalable outline using <code>bdftops.ps</code> .  Run the
shell command

<blockquote><code>
bdftops&nbsp;BDF_filename&nbsp;[AFM_file1_name&nbsp;...]&nbsp;gsf_filename&nbsp;fontname<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;UniqueID&nbsp;[XUID]&nbsp;[encodingname]
</code></blockquote>

<p>
The arguments have these meanings:
<blockquote><table cellpadding=0 cellspacing=0>
<tr valign=top>	<td><code>BDF_filename</code>
	<td>&nbsp;&nbsp;
	<td>Input bitmap file in BDF format
	<td>&nbsp;&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>AFM_file1_name</code>
	<td>&nbsp;
	<td>AFM files giving metrics
	<td>&nbsp;
	<td>(Optional)
<tr valign=top>	<td><code>gsf_filename</code>
	<td>&nbsp;
	<td>Output file
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>fontname</code>
	<td>&nbsp;
	<td>Name of the font
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>UniqueID</code>
	<td>&nbsp;
	<td>UniqueID (<a href="#Unique_IDs">as described below</a>)
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>XUID</code>
	<td>&nbsp;
	<td>XUID, in the form <code>n1.n2.n3...</code> (<a href="#Unique_IDs">as described below</a>)
	<td>&nbsp;
	<td>(Optional)
<tr valign=top>	<td><code>encodingname</code>
	<td>&nbsp;
	<td>"StandardEncoding" (the default), "ISOLatin1Encoding",<br>"SymbolEncoding", "DingbatsEncoding"
	<td>&nbsp;
	<td>(Optional)
</table></blockquote>

<p>
For instance

<blockquote><code>
bdftops&nbsp;pzdr.bdf&nbsp;ZapfDingbats.afm&nbsp;pzdr.gsf&nbsp;ZapfDingbats&nbsp;4100000&nbsp;1000000.1.41
</code></blockquote>

<p>
Then make an entry in Fontmap for the <code>.gsf</code>
file (<code>pzdr.gsf</code> in the example) as
<a href="#Add_fonts">described above</a>.

<hr>

<h2><a name="For_developers"></a>For developers only</h2>

<p>
The rest of this document is very unlikely to be of value to ordinary
users.

<h3><a name="Font_contents"></a>Contents of fonts</h3>

<p>
As noted above, Ghostscript accepts fonts in the same formats as PostScript
interpreters.  Type 0, 1, and 3 fonts are documented in the PostScript
Language Reference Manual (Second Edition); detailed documentation for Type
1 fonts appears in a separate Adobe book.  Type 2 (compressed format) fonts
are documented in separate Adobe publications.  Type 4 fonts are not
documented anywhere; they are essentially Type 1 fonts with a BuildChar or
BuildGlyph procedure.  Types 9, 10, and 11 (CIDFontType 0, 1, and 2) and
Type 32 (downloaded bitmap) fonts are documented in Adobe supplements.
Type 42 (encapsulated TrueType) fonts are documented in an Adobe
supplement; the TrueType format is documented in publications available
from Apple and Microsoft.  Ghostscript does not support Type 14 (Chameleon)
fonts, which use a proprietary Adobe format.

<h3><a name="Unique_IDs"></a>Font names and unique IDs</h3>

<p>
If you create your own fonts and will use them only within your own
organization, you should use <code>UniqueID</code> values between
4000000 and 4999999.

<p>
If you plan to distribute fonts, ask Adobe to assign you some UniqueIDs and
also an <code>XUID</code> for your organization. Contact

<blockquote><address>
Unique ID Coordinator<br>
Adobe Developers Association<br>
Adobe Systems, Inc.<br>
345 Park Avenue<br>
San Jose, CA  95110-2704<br>

+1-408-536-6883 fax<br>
<a href="mailto:fontdev-person@adobe.com">fontdev-person@adobe.com</a><br>
</address></blockquote>

<p>
The XUID is a Level 2 PostScript feature that serves the same function as
the UniqueID, but is not limited to a single 24-bit integer.  The
<code>bdftops</code> program creates XUIDs of the form
"<code>[-X-&nbsp;0&nbsp;-U-]</code>" where "<tt><b>-X-</b></tt>" is the
organization XUID and "<code>-U-</code>" is the UniqueID.  (Aladdin
Enterprises' organization XUID, which appears in a few places in various
font-related files distributed with Ghostscript, is 107; do not use this for
your own fonts that you distribute.)

<hr>

<h2><a name="Use_gs_fonts_with_X"></a>Using Ghostscript fonts on X Windows displays</h2>

<p>
The standard X11 distribution can display various kinds of fonts, including
the Adobe Type 1 format, so font files distributed with Ghostscript can be
used on X Windows displays.  Beginning with Ghostscript version 6.0, the
font archive contains the directory files needed to map Ghostscript's font
files to XLFDs.  Those files are named "<code>fonts.dir</code>" and
"<code>fonts.scale</code>".  There are two main methods to configure
your display to use these files.

<ul>
<li><a href="#Using_xset">With <code>xset</code></a> any user can add a
new directory to the font search path for the duration of a session.
<li>An administrator with root access can <a
href="#Font_permanent_installation">add the Ghostscript font directory
permanently</a> to the <a href="#X_font_catalog">X font server's
catalog</a> or to an <a href="#Xfree86_fontpath">X display server's list of
directories</a>.
</ul>

<h3><a name="Using_xset"></a>Using <code>xset</code></h3>

<p>
Users without root access can add the Ghostscript font directories to the
font search path using <code>xset</code>. Such a setting is transient
and must be repeated each time the display server is reset or restarted,
typically at login, so the call to <code>xset</code> should be added to
the user's "<code>.xsession</code>" or "<b><tt>.xinitrc</tt></b>"
startup script to make the fonts available at each login.

<p>
To add a new font directory, invoke <code>xset</code> like this:

<blockquote>
<code>xset fp+ <em>{directory}</em></code>
</blockquote>

<p>
where <b><em>{directory}</em></b> is the full pathname to the directory
containing the fonts on the host running the X display server.  For common
Ghostscript installations the path is

<blockquote>
<code>/usr/local/Ghostscript/share/fonts</code>
</blockquote>

<h3><a name="Font_permanent_installation"></a>Permanent installation</h3>

<p> A system administrator, or anyone with the necessary root privilege,
can make Ghostscript's fonts permanently available to the managed X display
servers.  This setup depends on the servers and the methods used
to make the fonts available.

<h4><a name="Configure_xfs"></a>Configuring the <code>xfs</code> font server</h4>

<p>
An X display server can obtain its font resources from a dedicated X font
server.  <code>xfs</code> is a prototype font server included in the X
Consortium X11 distribution.  It is configured with a file located in a
directory whose exact location is installation-dependent and could be any
of

<blockquote><code>
/usr/lib/X11/fs/config
<br>/usr/X11/lib/X11/fs/config
<br>/usr/X11R6/lib/X11/fs/config
</code></blockquote>

<p>
or some similar name. You can also use <code>xfs</code>'s
"<code>-config</code>" command-line option to specify the location of
the configuration file.

<p><a name="X_font_catalog"></a>
The configuration file designates a list ("catalog") of directories, each
of which contains fonts and a font mapping database (the file
"<code>fonts.dir</code>").  This list is specified with the
"<code>catalogue=</code>" keyword followed by a list of absolute
directory paths separated by commas.  To add the Ghostscript directory,
include its full name in the catalog list, for example:

<blockquote><code>
catalogue&nbsp;=&nbsp;/usr/local/share/Ghostscript/fonts/,
<br>/usr/X11R6/lib/X11/fonts/misc/,
<br>/usr/X11R6/lib/X11/fonts/Speedo/,
<br>/usr/X11R6/lib/X11/fonts/Type1/,
<br>/usr/X11R6/lib/X11/fonts/75dpi/,
<br>/usr/X11R6/lib/X11/fonts/100dpi/
</code></blockquote>

<p>
The fonts are searched in the order the directories are specified, so an
XLFD mapped by the Ghostscript directory could shadow a previous similar
description specified in the following directories.  Once the file is
modified, instruct the font server to reload the configuration file by
sending it the USR1 signal:

<blockquote>
<code>kill -HUP <em>{pid}</em></code>
</blockquote>

<p>
where <code><em>{pid}</em></code> is the font server process's numeric 
process
ID, as obtained with the "<code>ps</code>" command. Be sure to check
that the server is still alive after signaling it: it is very picky and
could decide to shut itself down if something is wrong in the new
configuration. If this happens, restart the server by hand and try to
figure out from its output what's happening. If the font server dies,
display servers using it will experience problems, so be sure to send the
signal from the console or from a display not using that font server!

<h4><a name="Configure_Xfree86"></a>Xfree86 display servers</h4>

<p><a name="Xfree86_fontpath"></a>
With the family of Xfree86 display servers, adding a new font directory
permanently requires editing the "<code>/etc/XF86Config</code>" setup
file to add a new "<code>FontPath</code>" to the "<b><tt>Files</tt></b>"
section:

<blockquote>
<code>Section "Files"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;RgbPath&nbsp;&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/rgb"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/local/share/Ghostscript/fonts"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/fonts/misc:unscaled"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/fonts/75dpi:unscaled"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/fonts/100dpi:unscaled"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/fonts/Type1"
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FontPath&nbsp;&nbsp;&nbsp;"/usr/X11R6/lib/X11/fonts/Speedo"
<br>EndSection</code>
</blockquote>

<p>
The fonts are searched in the order the directories are specified, so an
XLFD mapped by the Ghostscript directory could shadow a previous similar
description specified in the following directories.  Once this global
configuration is edited, the new fonts become available to all Xfree86
servers in use on that host. If a server is running, it must be restarted
to take effect: just quit the current session in the usual way.  If the
server is under the control of <code>xdm</code>, you may have to kill
it, because it is usually reset only between successive sessions.
