 resolution-independent measure used by the typesetting industry) via the following equation:</p>
<pre class="text">
size_points = (size_pixels * 72)/resolution
</pre>
<p>where resolution is in dots-per-inch (DPI). This means that at the default image resolution, there is one pixel per point.</p>
<p>Note that a font's pointsize is only a first-order approximation of the font height (ascender + descender) in points. The relationship between the specified pointsize and the rendered font height is determined b
