앗 감사합니다. TImage에 Transparent를 true로 하니까 되는군요...
^^;;
유영인 Cuperido 님이 쓰신 글 :
: 어떻게 안되는지 올려주셨으면 좋았었을텐데요..
: 제가 아래 코드를 테스트 해보니, 잘 동작 하는 것 같던데요..
:
: 혹시 아래 그림을 그대로 Image1에 Assign시키셨다든지..
: 이렇게만 하지 않으셨으면 잘 동작 할 겁니다.
: (Image에 바로 하실거면, Image1->Transparent = true 이런식으로 켜 주셔서
: Image가 사용하는 Bitmap을 이용하셔야 합니다)
:
: 그리고 MS에서 TransparentBitmap 에 대한 버그가 있어서
: MSDN을 통해서 재 배포한 적이 있었습니다.
: 이 것은 그것에 맞게 빌더로 수정한 예제고요.
: (Main->BITMAP_BUFFER는 속도 향상을 위해서 밖으로 뺀 Bitmap 객체입니다)
