<a name="cairo-hint-style-t"></a><h3>enum cairo_hint_style_t</h3>
<p>Specifies the type of hinting to do on font outlines. Hinting
is the process of fitting outlines to the pixel grid in order
to improve the appearance of the result. Since hinting outlines
involves distorting them, it also reduces the faithfulness
to the original outline shapes. Not all of the outline hinting
styles are supported by all font backends.</p>
<p>New entries may be added in future versions.</p>

device space. Doing this improves the consistency of
letter and line spacing, however it also means that text
