  29  <P> JpGraph contains as default a standard set of bitmap fonts which
  30   only supports the standard ASCII 7-bit character set. In order to use
  31   accented characters, UTF-8, Chinese, Japanese, etc You need to download
  32   TTF fonts. Due to various legal issues no TTF fonts are supplied in the
  33   JpGraph package. To enable TTF fonts there are three alternatives:</P>
  34  <OL>
  35  <LI>If you are on a Windows platform you can just point to the TTF
  36   directory in JpGraph to the standard fonts directory (e.g
  37   C:\windows\fonts\)</LI>
  38  <LI>If you are on a Unix platform you can download and install the core
  39   MS WEB-initiative fonts from <A href="http://corefonts.sourceforge.net/">
  40  http://corefonts.sourceforge.net/</A></LI>
  41  <LI>It is also possible to use the Vera Bitstream TTF fonts available
  42   from <A href="http://www.gnome.org/fonts/">http://www.gnome.org/fonts/</A>
  43  </LI>
  44  </OL>
  45  <P> It is also necessary to make sure that the PHP installation supports
  46   TTF fonts (either through FreeType 1 or FreeType 2 libraries). I n
  47   addition some suitable TTF font files must also be available. To make
  48   the font files available for the library the directory path to the
  49   location of the font files must be specified in the configuration file,
  50   jpg-config.inc.php</P>
  51  <P> JpGraph uses a standard naming convention for the TTF font files in
  52   order to be able to find the correct font files. This naming convention
  53   follows the standard naming of the available font files.</P>
  54  <P> If the installation of the library is made on a computer running MS
  55   Windows then it is recommended to use the already available font files
  56   in Windows (usually located in C:\WINDOWS\FONTS).</P>
  57  <P> If the installation is made on a UNIX derivate running X11 then the
  58   font location can differ between versions and UNIX brands. One commonly
  59   used path is &quot;/usr/X11R6/lib/X11/fonts/truetype/&quot;.</P>
  60  <P> Finally we note that it is possible to install additional fonts not
  61   natively supported by the library. Since this requires augmenting the
  62   library files this is considered advanced use and not further discussed
  63   in this introduction.</P>
