(31) Using non-default fonts in PostScript
--------------------------------------------

This example illustrates several possibilities to create GMT plots
with non-default fonts. As these fonts are not part of the standard
PostScript font collection they have to be embedded in the PS- or
PDF-file with Ghostscript. See also
Cookbook Section :ref:`non-default-fonts` for further information. The script
includes the following steps:

-  create a ``PSL_custom_fonts.txt`` file;

-  set the GMT parameters ``MAP_DEGREE_SYMBOL``, ``PS_CHAR_ENCODING``, and ``FONT``;

-  replace the default Helvetica font in the GMT-PostScript-File with sed;

-  create a PostScript-File with outlined fonts (optional);

-  convert GMT's PostScript output to PDF or any image format (optional).

The script produces the plot in Figure. All
standard fonts have been substituted by the free OpenType fonts Linux
Libertine (title) and Linux Biolinum (annotations). Uncomment the
appropriate lines in the script to make a PostScript-file with
outlined fonts or to convert to a PDF-file.
