The ((<cairo_fill()|URL:http://www.cairographics.org/manual/cairo-cairo-t.html#cairo-fill>)) operation instead uses the path like the lines of a coloring book, and allows the source through the mask within the hole whose boundaries are the path. For complex paths (paths with multiple closed sub-paths様ike a donut熔r paths that self-intersect) this is influenced by the ((<fill rule|URL:http://www.cairographics.org/manual/cairo-cairo-t.html#cairo-set-fill-rule>)). Note that while stroking the path transfers the source for half of the line width on each side of the path, filling a path fills directly up to the edge of the path and no further.
