ROP모드
dwRop는 현재 화면에 출력되는 이미지와 출력하고자 하는 이미지를 조합하는 연산을 말한다.
| 매크로 상수 | 설명 |
| NOTSRCERASE | 화면색과 비트맵 색을 or 연산후 반전 |
| NOTSRCCOPY | 비트맵을 반전 |
| PATCOPY | 현재 선택된 브러시로 칠함 |
| PATNVERT | 브러시와 화면색을 XOR 연산 |
| SRCAND | 비트맵과 화면색을 AND 연산 |
| SRCCOPY | 비트맵을 그대로 화면으로 출력 |
| SRCPAINT | 비트맵과 화면을 OR연산 |
| WHITENESS | 무조건 흰색으로 칠함 |
| BLACKNESS | 무조건 검정색으로 칠함 |
| DSTINVERT | 회면색을 반전 |
| MERGECOPY | 브러시와 비트맵의 색을 AND 연산 |
타이머를 이용하여 0.1초마다 함수를 호출하여 움직이는 이미지를 만들어 보자.
