干脆帮你写好 哇哈哈 太好玩了procedure TForm1.ListBox1Click(Sender: TObject);
var
  i:integer;
  ImgGUID: TGUID;
begin
  //你可以在这里对Listbox1进行循环 获取每一帧的图片
  for  i:=0 to ListBox1.Items.Count-1 do
  begin
  //GifFrame := ListBox1.ItemIndex;
  //img.SelectActiveFrame(FrameDimensionTime, GifFrame);
  img.SelectActiveFrame(FrameDimensionTime, i);
  GetEncoderClsid('image/bmp', ImgGUID);
  img.Save('c:\test'+inttostr(i)+'.bmp',ImgGUID);
  //Repaint;
  end;
end;
