<para>
|
|
A <classname>CairoFillRule</classname> is used to select how paths are filled. For both fill rules, whether or not a
|
|
point is included in the fill is determined by taking a ray from that point to infinity and looking at intersections
|
|
with the path. The ray can be in any direction, as long as it doesn't pass through the end point of a segment or have
|
|
a tricky intersection such as intersecting tangent to the path. (Note that filling is not actually implemented in
|
|
this way. This is just a description of the rule that is applied.)
|
|
</para>
|
|
<para>
|
|
The default fill rule is <constant>CairoFillRule::WINDING</constant>.
