<h1>html2ps/pdf configuration files and options</h1>
<p><a href="index.html">Back to table of contents</a></p>

<p>Currently, configuration is done both via configuration file (<tt>html2ps.config</tt>) 
  and configuration constants inside the <tt>config.inc.php</tt> file.

    <td>Top level</td>
    <td> Defines the output media size. This tag should have three arguments:

      For example, normally 'times' family is mapped to /Times-Roman font. On 
      the other hand, this standard font does not contain cyrillic symbols, so 
      when one of the cyrillic encodings is met, 'times' will be mapped to /TimesCyr-Medium.</td>

Path to directory on server where HTML2PS script files reside. All HTML2PS-specific directories and 
paths are relative to this directory.
</td>

<tr class="odd">
<td>DEFAULT_USER_AGENT</td>
<td>
Value of the 'User-Agent' HTTP header which will be sent by PHP when fetching files from remote server.

HTTP headers nor in META tag of HTML page).
</td>

<tr class="even">
<td>FILE_PROTOCOL_RESTRICT</td>
<td>
Determines the prefix of the filesystem path allowed to be referred via 'file' protocol. By default,
you may refer files in html2ps directory and below; to use files from <tt>C:\images</tt> directory you'll need to 
store <tt>C:\images\</tt> value in this constant. Note the trailing backslash; if it is omitted, the prefix may match several directories, 
e.g. both <tt><b>C:\images</b>\</tt> and <tt><b>C:\images</b>-private\</tt>.

Determines how font files are embedded. May be:
<ul>
<li>'all' &mdash; embed all fonts</li>
<li>'none' &mdash; do not embed any fonts</li>
