| <p>This directory contains font support for NuttX. The contents of this directory |
| are only build if CONFIG_NXFONTS is defined in the NuttX configuration file.</p> |
| <section id="installing-new-fonts"> |
| <h2>Installing New Fonts<a class="headerlink" href="#installing-new-fonts" title="Permalink to this heading"></a></h2> |
| <p>There is a tool called bdf-converter in the directory tools/. The bdf-converter |
| program be used to convert fonts in Bitmap Distribution Format (BDF) |
| into fonts that can be used in the NX graphics system.</p> |
| <p>Below are general instructions for creating and installing a new font |
| in the NX graphic system:</p> |
| <ol class="arabic simple"> |
| <li><p>Locate a font in BDF format,</p></li> |
| <li><p>Use the bdf-converter program to convert the BDF font to the NuttX |
| font format. This will result in a C header file containing |
| definitions. That header file should be installed at, for example, |
| <code class="docutils literal notranslate"><span class="pre">graphics/nxfonts/nxfonts_myfont.h</span></code>.</p></li> |
| </ol> |
| <p>Create a new NuttX configuration variable. For example, suppose |
| you define the following variable: CONFIG_NXFONT_MYFONT. Then |
| you would need to:</p> |
| <ol class="arabic simple"> |
| <li><p>Define <code class="docutils literal notranslate"><span class="pre">CONFIG_NXFONT_MYFONT=y</span></code> in your NuttX configuration file.</p></li> |
| </ol> |
| <p>A font ID number has to be assigned for each new font. The font ID |
| is defined in the file <code class="docutils literal notranslate"><span class="pre">include/nuttx/nx/nxfonts.h</span></code>. Those definitions |
| have to be extended to support your new font. Look at how the font ID |
| enabled by <code class="docutils literal notranslate"><span class="pre">CONFIG_NXFONT_SANS23X27</span></code> is defined and add an ID for your |
| new font in a similar fashion:</p> |
| <ol class="arabic" start="3"> |
| <li><p><code class="docutils literal notranslate"><span class="pre">include/nuttx/nx/nxfonts.h</span></code> Add you new font as a possible system |
