Graphics::TBitmap *Bmp;
Bmp=new Graphics::TBitmap;
Bmp->Width=Image1->ClientWidth;Bmp->Height=Image1->ClientHeight;
Image1->Picture->Graphic=Bitmap;
Bmp->Canvas->Draw(0,0,Image1->Picture->Bitmap);
BitBlt(Image1->Canvas->Handle,0,0,Image1->ClientWidth,Image1->ClientHeight,
Bmp->Canvas->Handle,0,0,NOTSRCCOPY);
這段程式有什麼問題嗎？ 為什麼執行出來是一片黑
