<h1>Source code for matplotlib.font_manager</h1><div class="highlight"><pre>
<span></span><span class="sd">"""</span>
<span class="sd">A module for finding, managing, and using fonts across platforms.</span>
<span class="sd">This module provides a single :class:`FontManager` instance that can</span>
<span class="sd">be shared across backends and platforms. The :func:`findfont`</span>
<span class="sd">function returns the best TrueType (TTF) font file in the local or</span>
<span class="sd">system font path that matches the specified :class:`FontProperties`</span>
<span class="sd">instance. The :class:`FontManager` also handles Adobe Font Metrics</span>
<span class="sd">(AFM) font files for use by the PostScript backend.</span>
<span class="sd">The design is based on the `W3C Cascading Style Sheet, Level 1 (CSS1)</span>
<span class="sd">font specification <http://www.w3.org/TR/1998/REC-CSS2-19980512/>`_.</span>
<span class="sd">Future versions may implement the Level 2 or 2.1 specifications.</span>
<span class="sd">Experimental support is included for using `fontconfig` on Unix</span>
<span class="sd">variant platforms (Linux, OS X, Solaris). To enable it, set the</span>
<span class="sd">constant ``USE_FONTCONFIG`` in this file to ``True``. Fontconfig has</span>
<span class="sd">the advantage that it is the standard way to look up fonts on X11</span>
<span class="sd">platforms, so if a font is installed, it is much more likely to be</span>
<span class="sd">found.</span>

<span class="sd"> - documentation</span>
<span class="sd"> - font variant is untested</span>
<span class="sd"> - font stretch is incomplete</span>
<span class="sd"> - font size is incomplete</span>
<span class="sd"> - default font algorithm needs improvement and testing</span>
<span class="sd"> - setWeights function needs improvement</span>
<span class="sd"> - 'light' is an invalid weight value, remove it.</span>

<span class="sd">"""</span>
<span class="sd"> A class for storing and manipulating font properties.</span>
<span class="sd"> The font properties are those described in the `W3C Cascading</span>
<span class="sd"> Style Sheet, Level 1</span>
<span class="sd"> <http://www.w3.org/TR/1998/REC-CSS2-19980512/>`_ font</span>
<span class="sd"> specification. The six properties are:</span>
<span class="sd"> - family: A list of font names in decreasing order of priority.</span>
<span class="sd"> The items may include a generic font family name, either</span>
<span class="sd"> 'serif', 'sans-serif', 'cursive', 'fantasy', or 'monospace'.</span>
<span class="sd"> In that case, the actual font to be used will be looked up</span>
<span class="sd"> from the associated rcParam in :file:`matplotlibrc`.</span>
<span class="sd"> - style: Either 'normal', 'italic' or 'oblique'.</span>
<span class="sd"> - variant: Either 'normal' or 'small-caps'.</span>
<span class="sd"> - stretch: A numeric value in the range 0-1000 or one of</span>
<span class="sd"> 'ultra-condensed', 'extra-condensed', 'condensed',</span>
<span class="sd"> 'semi-condensed', 'normal', 'semi-expanded', 'expanded',</span>
<span class="sd"> 'extra-expanded' or 'ultra-expanded'</span>
<span class="sd"> - weight: A numeric value in the range 0-1000 or one of</span>
<span class="sd"> 'ultralight', 'light', 'normal', 'regular', 'book', 'medium',</span>
<span class="sd"> 'roman', 'semibold', 'demibold', 'demi', 'bold', 'heavy',</span>
<span class="sd"> 'extra bold', 'black'</span>
<span class="sd"> - size: Either an relative value of 'xx-small', 'x-small',</span>
<span class="sd"> 'small', 'medium', 'large', 'x-large', 'xx-large' or an</span>
<span class="sd"> absolute font size, e.g., 12</span>
<span class="sd"> The default font property for TrueType fonts (as specified in the</span>
<span class="sd"> default :file:`matplotlibrc` file) is::</span>
<span class="sd"> sans-serif, normal, normal, normal, normal, scalable.</span>
<span class="sd"> Alternatively, a font may be specified using an absolute path to a</span>
<span class="sd"> .ttf file, by using the *fname* kwarg.</span>
<span class="sd"> The preferred usage of font sizes is to use the relative values,</span>
<span class="sd"> e.g., 'large', instead of absolute font sizes, e.g., 12. This</span>
<span class="sd"> approach allows all text sizes to be made larger or smaller based</span>
<span class="sd"> on the font manager's default font size.</span>
<span class="sd"> This class will also accept a `fontconfig</span>
<span class="sd"> <https://www.freedesktop.org/wiki/Software/fontconfig/>`_ pattern, if it is</span>
<span class="sd"> the only argument provided. See the documentation on `fontconfig patterns</span>
<span class="sd"> <https://www.freedesktop.org/software/fontconfig/fontconfig-user.html>`_.</span>
<span class="sd"> This support does not require fontconfig to be installed. We are merely</span>
<span class="sd"> borrowing its pattern syntax for use here.</span>
<span class="sd"> Note that matplotlib's internal font manager and fontconfig use a</span>
<span class="sd"> different algorithm to lookup fonts, so the results of the same pattern</span>
<span class="sd"> may be different in matplotlib than in other applications that use</span>
<span class="sd"> fontconfig.</span>
