$hMatrix = _GDIPlus_MatrixCreate()
_GDIPlus_MatrixRotate($hMatrix, $nAngle, "False")
_GDIPlus_GraphicsSetTransform($hGraphic, $hMatrix)
_GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage2, 0 - $iW , 0-$iH, $iW, $iH)
_GDIPlus_MatrixDispose($hMatrix)

_GDIPlus_ImageSaveToFileEx($hImage1,$fiename, $CLSID)
_GDIPlus_ImageDispose($hImage1)
_GDIPlus_ImageDispose($hImage2)
_GDIPlus_GraphicsDispose ($hGraphic)
_WinAPI_DeleteObject($hBMP)
_GDIPlus_Shutdown()
EndFunc本人将这段由大侠35888894 写的代码，原地址http://www.autoitx.com/forum.php?mod=viewthread&tid=36345&highlight=%B7%AD%D7%AA改写成旋转180度的代码，可是改了半天总是图像缺失的很厉害。
就是这一句怎么改都改的不是那么如意 _GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage2, 0 - $iW , 0-$iH, $iW, $iH)希望大家能帮帮忙。 #include <GDIPlus.au3>
_GDIPlus_ImageRotateToSave('1.jpg', '111.jpg')
Func _GDIPlus_ImageRotateToSave($sPicPath, $sNewName)
_GDIPlus_Startup()
Local $hImage = _GDIPlus_ImageLoadFromFile($sPicPath)
DllCall($ghGDIPDll, 'uint', 'GdipImageRotateFlip', 'hwnd', $hImage, 'int', 2)
_GDIPlus_ImageSaveToFile($hImage, $sNewName)
_GDIPlus_ImageDispose($hImage)
_GDIPlus_Shutdown()
EndFunc ;==>_GDIPlus_ImageRotateToSave 哇，A版就是强，每次出手都极为完美！谢谢祝周末愉快！
