放大镜指针调准问题

askask150

Global $SRCCOPY = 0x00CC0020
Global $leave = 0

HotKeySet("","leave")

SplashTextOn ( "AU3MAG", "" , 100 , 100 , 0, 0, 1 )
$MyhWnd = WinGetHandle("AU3MAG")

While Not $leave
  Sleep(25)
   MAG()
WEnd

Func MAG()
  $MyHDC = DLLCall("user32.dll","int","GetDC","hwnd",$MyhWnd)
  If @error Then Return
  $DeskHDC = DLLCall("user32.dll","int","GetDC","hwnd",0)
  If Not @error Then
     $xy = MouseGetPos()
     If Not @error Then
        $l = $xy[0]-10
        $t = $xy[1]-10
        DLLCall("gdi32.dll","int","StretchBlt","int",$MyHDC[0],"int",0,"int",0,"int",100,"int",100,"int",$DeskHDC[0],"int",  $l,"int",$t,"int",20,"int",20,"long",$SRCCOPY)
     EndIf
     DLLCall("user32.dll","int","ReleaseDC","int",$DeskHDC[0],"hwnd",0)
  EndIf
  DLLCall("user32.dll","int","ReleaseDC","int",$MyHDC[0],"hwnd",$MyhWnd)
EndFunc

Func leave()
  $leave = 1
EndFunc

上面这断是放大镜的代码，但它的范围太小 ，我想把范围扩大  但扩大后 指帧却不准了  想问大大门 如果扩大 要调整哪些数值  ，，，，，我想做出如  http://www.autoitx.com/forum.php ... &extra=page%3D1    补助软件中的 确定坐标时 那种放大镜的效果

SplashTextOn ( "AU3MAG", "" , 200 , 200 , 0, 0, 1 )  ;基本的显示尺寸定义行
DLLCall("gdi32.dll","int","StretchBlt","int",$MyHDC[0], _
                                "int",0,"int",0,"int",200,"int",200,"int",$DeskHDC[0], _
                                "int",  $l,"int",$t,"int",50,"int",50,"long",$SRCCOPY) ;回显的尺寸定义
;看其中的修改，就知道什么回事

If Not @error Then
        $l = $xy[0]-10
        $t = $xy[1]-10


这个呢  有什么用？
为什么指针在这个窗口准 在另外一个窗口就不准

是因不同情况而设的偏移，窗口的不同有可能引起改变
