能给我注释一下面函数吗,偶看不太懂
Func SetBitmap($hGUI, $hImage, $iOpacity)Local $hScrDC, $hMemDC, $hBitmap, $hOld, $pSize, $tSize, $pSource, $tSource, $pBlend, $tBlend
$hScrDC= _WinAPI_GetDC(0)
$hMemDC= _WinAPI_CreateCompatibleDC($hScrDC)
$hBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
$hOld= _WinAPI_SelectObject($hMemDC, $hBitmap)
$tSize = DllStructCreate($tagSIZE)
$pSize = DllStructGetPtr($tSize)
DllStructSetData($tSize, "X", _GDIPlus_ImageGetWidth ($hImage))
DllStructSetData($tSize, "Y", _GDIPlus_ImageGetHeight($hImage))
$tSource = DllStructCreate($tagPOINT)
$pSource = DllStructGetPtr($tSource)
$tBlend= DllStructCreate($tagBLENDFUNCTION)
$pBlend= DllStructGetPtr($tBlend)
DllStructSetData($tBlend, "Alpha" , $iOpacity)
DllStructSetData($tBlend, "Format", $AC_SRC_ALPHA)
_WinAPI_UpdateLayeredWindow($hGUI, $hScrDC, 0, $pSize, $hMemDC, $pSource, 0, $pBlend, $ULW_ALPHA)
_WinAPI_ReleaseDC (0, $hScrDC)
_WinAPI_SelectObject($hMemDC, $hOld)
_WinAPI_DeleteObject($hBitmap)
_WinAPI_DeleteDC($hMemDC)
_GDIPlus_ShutDown ()
EndFunc 获得当前的设备上下文，在上面绘制一个图像并设置alpha通道透明……
你不必看得懂，只要会用就行了。

偶想活用它,当然得看明白是什么意思,要不然稀理糊涂了
