//创建一个BITMAP来存放图象 Fullscreen.Width:=screen.width; Fullscreen.Height:=screen.Height; DC:=GetDC(0); //取得屏幕的DC，参数0指的是屏幕 FullscreenCanvas:=TCanvas.Create; //创建一个CANVAS对象 FullscreenCanvas.Handle:=DC; Fullscreen.Canvas.CopyRect(Rect(0,0,screen.Width,screen.Height), fullscreenCanvas,Rect(0,0,Screen.Width,Screen.Height)); //把整个屏幕复制到BITMAP中 FullscreenCanvas.Free;
