<div class="ui explanation">
<h5>Importing or creating a font:</h5>
You can either:
<ul>
<li>Extract a font by copying & pasting the existing font source (a <kbd>.h</kbd> file) in the textarea above</li>
<li>Create a new font with a single character</li>
</ul>
<h5>Adding characters:</h5>
<p>You can easily add new characters to the font afterwards. Interval characters will be added automatically <em>as disabled glyphs</em>.</p>
</div>
</div>
<div class="eleven wide column">
<div class="ui explanation">
<h5>Editing glyphs:</h5>
Glyphs can be edited individually. You can:
<ul>
<li>Enable or disable the glyph</li>
<li>Edit each pixel of the glyph</li>
<li>Edit all values present in the GFXglyph data structure (See <a href="https://learn.adafruit.com/creating-custom-symbol-font-for-adafruit-gfx-library/understanding-the-font-specification">Adafruit documentation</a> for more information)</li>
</ul>
<h5>When exporting, you can either :</h5>
<ul>
<li>Select a range of characters to include in the output. Characters outside of this range will <strong>not</strong> be included in the bitmap nor in the glyphs table.</li>
<li>Disable individual characters. The disabled characters get all values set to <kbd>0</kbd>. There still are entries for the disabled characters in the glyphs table, but no data in the bitmap for them — this keeps the characters in their correct places in the ASCII table.</li>
</ul>
