Closes path cliping.
Delphi 語法: procedure EoClip;
C++ 語法: void __fastcall EoClip( void );
說明 透過將目前 clipping path 與目前 path 相交來修改 clipping path,並使用 even-odd rule 判斷哪些 regions 位於 clipping path 內 Even-Odd Rule 详细说明Picture shows the effects of applying the even-odd rule to complex paths. For the five-pointed star, the rule considers the triangular points to be inside the path, but not the pentagon in the center. For the two concentric circles, only the "doughnut" shape between the two circles is considered inside, regardless of the directions in which the circles are drawn.
