Context.setFillRule
void setFillRule(cairo.types.FillRule fillRule)Set the current fill rule within the cairo context. The fill rule is used to determine which regions are inside or outside a complex (potentially self-intersecting) path. The current fill rule affects both [cairo.context.Context.fill] and [cairo.context.Context.clip]. See #cairo_fill_rule_t for details on the semantics of each available fill rule.
The default fill rule is [cairo.types.FillRule.Winding].
Parameters
fillRule | a fill rule, specified as a #cairo_fill_rule_t |
