如何截获桌面上的图案(100分)

我想通过鼠标选定区域，然后把选定区域的图案保存下来

这个比较难办,但反过来就容易了.<br>先把桌面保存下来,再选定区域.

怎么保存

procedure TForm1.Button1Click(Sender: TObject);<br>var<br>&nbsp; DC: HDC;<br>&nbsp; Canvas: TCanvas;<br>begin<br>&nbsp; DC:=GetDC(0);<br>&nbsp; try<br>&nbsp; &nbsp; Canvas:=TCanvas.Create;<br>&nbsp; &nbsp; try<br>&nbsp; &nbsp; &nbsp; Canvas.Handle:=DC;<br>&nbsp; &nbsp; &nbsp; Image1.Canvas.CopyRect(Rect(0, 0, Screen.Width, Screen.Height), Canvas, Rect(0, 0, Screen.Width, Screen.Height));<br>&nbsp; &nbsp; finally<br>&nbsp; &nbsp; &nbsp; Canvas.Free<br>&nbsp; &nbsp; end<br>&nbsp; finally<br>&nbsp; &nbsp; ReleaseDC(0, DC)<br>&nbsp; end<br>end;<br>

借花献佛啦，这是高先超大侠的作品，实在不很不错啊！附源码，完全满足你的要求。<br>http://kuga.51.net/download/files/snag.zip

能取mediaplay的图片吗,下载不了

mediaplay用的是DirectShow，用DC是截不了。
