<title>Introduction to <application><acronym>FOP</acronym></application></title>

<para>The <application><acronym>FOP</acronym></application> (Formatting 
Objects Processor) package contains a print formatter driven by 
<acronym>XSL</acronym> formatting objects 
(<acronym>XSL</acronym>-<acronym>FO</acronym>). It is a 
<application>Java</application> application that reads a formatting object 
tree and renders the resulting pages to a specified output. Output formats 
currently supported include <acronym>PDF</acronym>, <acronym>PCL</acronym>, 
PostScript, <acronym>SVG</acronym>, <acronym>XML</acronym> (area tree 
representation), print, <acronym>AWT</acronym>, <acronym>MIF</acronym> and 
<acronym>ASCII</acronym> text. The primary output target is 
<acronym>PDF</acronym>.</para>

<para>You'll need to install one additional <application>Java</application>

of the <ulink url="http://xml.apache.org/batik/">Batik</ulink> package, but is 
also included with the <application><acronym>FOP</acronym></application> 
package. If you have <application>Batik</application> installed, ensure the 
<filename>batik.jar</filename> library is included in your 
<envar>$CLASSPATH</envar> environment variable. Alternatively, create a 
symbolic link from <filename>/opt/fop-&fop-version;/lib/batik.jar</filename> 
pointing to the full path of the installed <filename>batik.jar</filename> 
file so that the <command>fop.sh</command> script will automatically pick it 
up.</para>

<para>If you don't have the <application>Batik</application> package installed, 
run the following commands as the root user:</para>

<screen><userinput role='root'><command>install -v -m644 lib/batik.jar /opt/fop-&fop-version;/lib &amp;&amp;

<acronym>XSL</acronym> transformations. If you have the 
<application>Xalan-Java</application> package installed, skip to the next 
section.</para>

<para>If you wish to install the <application>Xalan-Java</application> 
components provided by the <application><acronym>FOP</acronym></application>

<title>Command explanations</title>

<para><command>yes | $FOP_BUILD_DIR/../jai-...-jdk.bin</command>: This command 
installs the <application><acronym>JAI</acronym></application> components 
into the <application><acronym>JDK</acronym></application> file structure. The 
<command>yes</command> command is piped through so that you don't have to 
scroll through four pages of the license agreement and automatically responds 
<quote>yes</quote> to the agreement. <envar>$FOP_BUILD_DIR</envar> is used as 
a reference point to the source executable and as a method to return back to 
the <application><acronym>FOP</acronym></application> source tree.</para>

<para><command>sed -i -e "s/build/lib/" ...</command>: These commands modify 
the installed shell scripts so that the location of the installed 
<filename>fop.jar</filename> file is correctly identified.</para>

<para><command>install -v ...; cp -v ...</command>: There is no installation 
script provided by the <application><acronym>FOP</acronym></application> 
package. These commands install the package.</para>

<para><command>ln -svf fop-&fop-version; /opt/fop</command>: This creates a 
convenience symlink so that <envar>$FOP_HOME</envar> doesn't have to be 
changed each time there's a package version change.</para>

<sect3><title>Configuration Information</title>

<para>Using <application><acronym>FOP</acronym></application> to process some 
large <acronym>FO</acronym>'s (including the <acronym>FO</acronym> derived from 
the <acronym>BLFS</acronym> <acronym>XML</acronym> sources), can lead to memory 
errors. Unless you add a parameter to the <command>java</command> command used 
in the <command>fop.sh</command> script you may receive messages similar to the 
one shown below:</para>

<para><computeroutput>Exception in thread "main" java.lang.OutOfMemoryError: 
Java heap space</computeroutput></para>

<para>To avoid errors like this, you need to pass an extra parameter to the 
<command>java</command> command used in the <command>fop.sh</command> script. 
This can be accomplished by creating a <filename>~/.foprc</filename> (which 
is sourced by the <command>fop.sh</command> script) and adding the parameter 
to the <envar>FOP_OPTS</envar> environment variable.</para>

<para>The <command>fop.sh</command> script looks for a <envar>FOP_HOME</envar> 
environment variable to locate the 
<application><acronym>FOP</acronym></application> class libraries. You can 
create this variable using the <filename>~/.foprc</filename> file as 
well. Create a <filename>~/.foprc</filename> file using the following 
commands:</para>

<screen><userinput><command>cat &gt; ~/.foprc &lt;&lt; "EOF"</command>
FOP_OPTS="-Xmx<replaceable>[RAM_Installed]</replaceable>m"
FOP_HOME="/opt/fop"

<command>EOF</command></userinput></screen>

<para>Replace <replaceable>[RAM_Installed]</replaceable> with a number 
representing the amount of RAM installed in your computer. An example would 
be <userinput>FOP_OPTS="-Xmx768m"</userinput>. For more information about 
memory issues running <application><acronym>FOP</acronym></application>, see
<ulink url="http://xml.apache.org/fop/running.html#memory"/>.</para>

<para>To include the <command>fop.sh</command> script in your path, update 
your personal or system-wide profile with the following:</para>

<screen><userinput>PATH=$PATH:/opt/fop/bin</userinput></screen>
