我正在尝试检测窗口中的图像。窗口是 BlueStacks App Player。我正在使用 ImageSearch UDF。问题是它失败了。

$result = DllCall("ImageSearchDLL.dll","str","ImageSearch","int",$x1,"int",$y1,"int",$right,"int",$bottom,"ptr",$findImage)

DllCall()如果成功，则应返回一个数组，但返回1表示失败。我尝试了这个 UDF 的 x86 和 x64 版本。这就是我所说的_ImageSearchArea()：

_CaptureRegion()
_ImageSearchArea($gameImage,  0,0,0,500,500, $x, $y, 0)

我有 Windows 7 X64。还有 x64 AutoIt。窗口的分辨率为 577x690。这是我正在使用的 UDF：

$findImage 是一个字符串变量，因此 dll 调用应该如下所示。

$result = DllCall("ImageSearchDLL.dll","str","ImageSearch","int",$x1,"int",$y1,"int",$right,"int",$bottom,"str",$findImage)
