<FONT SIZE=5 COLOR="#FF0000"><B>Using Other Fonts</B></FONT></CENTER></H3>

<BR>

<P>The versions of Ghostscript come with a set of default fonts that you can use with any program capable of reading PostScript Type 1 and Type 3 fonts. If you have created your own Type 1 or Type 3 fonts, or have purchased some fonts from another source, 
you can use these with Ghostscript. Place your fonts in the lib/ghostscript/fonts directory. Then edit the lib/ghostscript/FontMap file to add a line telling Ghostscript where to find the font. For example,

<BR>

<BR>

<PRE>

<FONT COLOR="#000080">/Helvetica (hlv_xyz.pfb);</FONT></PRE>

<P>where hlv_xyz.pfb is the name of the font file you have just added. You do not have to reset any X resources for this to work. Simply place the file in the directory, edit the FontMap and restart gs.

<BR>

<P>Aladdin Enterprises, the inventors of Ghostscript, do not have the resources to respond to questions from general users of Ghostscript. There are plenty of other places where you can get very detailed information about Ghostscript.

<BR>

<P>If you have access to newsgroups, post your questions to gnu.ghostscript.bug. There are literally hundreds of Ghostscript users all over the world who are very willing to help you. After all, we all started learning on our own. Using this newsgroup is 
perhaps the quickest way to get more information on gs.

<BR>

<P>If you have access to Internet mail, but not news, send e-mail to <A HREF="mailto:<A NAME="I2"></A>[e-mail]">[e-mail]</A>. If you are having trouble with a specific device driver, look in the file devs.mak 
and see if it is a user-maintained driver. If so, please contact directly the person listed.

<BR>

<P>There are several files in the /usr/lib/ghostscript/doc directory which can provide more information. Some of these files are:

<BR>

<UL>

<LI>readme.doc Information about problems, major changes, and new features in the current release.

<BR>

<BR>

<LI>NEWS A detailed history of changes in the most recent Ghostscript releases.

<FONT SIZE=5 COLOR="#FF0000"><B>Summary</B></FONT></CENTER></H3>

<BR>

<P>This chapter scratched the surface of a very important PostScript processing program called Ghostscript. The executable file for Ghostscript is called gs. You can use gs to decode PostScript files for displaying or printing hard copies.

<BR>

<P>Ghostscript is also used by other programs as a filter for working with PostScript printers that cannot switch from PostScript to text and back just by looking at a document. In this case, the gs command is used to convert text to PostScript with an 
output filter for lp before sending the text to a PostScript printer. As another example, HylaFAX uses gs as its primary PostScript output filter program.

<BR>

<P>Ghostview is an X Window&#151;based program that provides a canvas for ghostscript to write its output to. Ghostview enables you to scroll through a multi-page document, zoom in and out, and save marked pages. The ability to view EPSI or PostScript via 
Ghostscript saves time and paper when typesetting documents.
