출력:

질문: 내 클리핑 경로는 폐쇄 회로입니다. 따라서 생산량은 자본의 외부 부분입니다.ㅏ. 편지 추출을 완료하려면 어떻게 해야 하나요?ㅏ---또한 잘라내기---문자의 적절한 내부 부분ㅏ?

감사합니다.

Answer 1

경로에 시계 반대 방향으로 "A"의 내부 삼각형을 추가합니다("0이 아닌 규칙" 사용).

(0.359,0.268) -- (0.48,0.73) -- (0.52,0.73) -- (0.64,0.27) -- (0.60,0.27) -- (0.562,0.403) -- (0.43,.403) -- (0.395, 0.268) -- (0.359,0.268) (0.440,0.438) -- (0.555,0.438) -- (0.498,0.675)  -- (0.44,0.44)

cycle닫힌 경로를 만들 때 첫 번째 좌표를 반복하는 대신 사용하는 것이 좋습니다 . 이렇게 하면 경로가 다음과 같이 됩니다.

(0.359,0.268) -- (0.48,0.73) -- (0.52,0.73) -- (0.64,0.27) -- (0.60,0.27) -- (0.562,0.403) -- (0.43,.403) -- (0.395, 0.268) -- cycle (0.440,0.438) -- (0.555,0.438) -- (0.498,0.675) -- cycle
