[已解决]]如何用ColorMatrix来设置imageattibutes来保存改亮度后相应位图句柄？

参考了happytc贴子http://www.autoitx.com/forum.php?mod=viewthread&tid=28816&highlight=%BB%D2%B6%C8
和seniors的贴子http://www.autoitx.com/forum.php?mod=viewthread&tid=38835&highlight=gdi%2B
想用 _ColorMatrix_set_lum（）返回一个更改亮度后的位图句柄以供 YzmToArray（）调用，搞不定。
请朋友们指点，谢谢先。#include <APIConstants.au3>

似乎这样可以了_GDIPlus_Startup()
Local $hfileBitmap = _GDIPlus_BitmapCreateFromFile($selected_image_file_listview_item);ok
;Local $hfileBitmap = _GDIPlus_ImageLoadFromFile($selected_image_file_listview_item); ok too

Local $hfileBitmap_clone = _GDIPlus_ImageClone($hfileBitmap)

_ColorMatrix_set_lum($hfileBitmap)
;$hfileBitmap = _ColorMatrix_set_lum($hfileBitmap,$hfileBitmap_clone)

   $YzmArray = YzmToArray($hfileBitmap)
   $oldBitMap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hfileBitmap)
   _GDIPlus_ImageDispose($hfileBitmap)
   ;_MemGlobalFree($hData)
   _GDIPlus_Shutdown()
   DllCall('psapi.dll', 'int', 'EmptyWorkingSet', 'hWnd', -1)
;_output_test($YzmArray)
   Return 1
EndFunc ;==>GetYzm
Func _ColorMatrix_set_lum($hfileBitmap)
   Local $hGraphics = _GDIPlus_ImageGetGraphicsContext($hfileBitmap)
Local $hIA = _GDIPlus_ImageAttributesCreate()

   _GDIPlus_ColorMatrixTranslate($tColorMatrix, $nBrightness, $nBrightness, $nBrightness, 0, 1)
