[Problem] _GDIPlus GUICtrlSetImage

[GameOverMan]

Witam,

_GDIPlus_Startup()
$hImage = _GDIPlus_ImageLoadFromFile("picture.jpeg")
$Widh = _GDIPlus_ImageGetWidth($hImage)
$Height = _GDIPlus_ImageGetHeight($hImage)
_GDIPlus_Shutdown()
GUICtrlSetImage($Pic1, "picture.jpeg")

 

Dlaczego GUICtrlSetImage nie działa po _GDIPlus_ImageLoadFromFile? Przed działa normalnie ale po nie.

Jak dotąd jedyne wyjście dla mnie to robienie kopii obrazka.

; Function Name:        Load_BMP_From_Mem
; Description:              Loads an image which is saved as a binary string and converts it to a bitmap or hbitmap
;
; Parameters:               $bImage:    the binary string which contains any valid image which is supported by GDI+
; Optional:                     $hHBITMAP:  if false a bitmap will be created, if true a hbitmap will be created
;
; Remark:                       hbitmap format is used generally for GUI internal images, $bitmap is more a GDI+ image format
;                                       Don't forget _GDIPlus_Startup() and _GDIPlus_Shutdown()
;
; Requirement(s):       GDIPlus.au3, Memory.au3 and _WinAPI_BitmapCreateDIBFromBitmap() from WinAPIEx.au3
; Return Value(s):      Success: handle to bitmap (GDI+ bitmap format) or hbitmap (WinAPI bitmap format),
;                                       Error: 0
; Error codes:              1: $bImage is not a binary string
;                                       2: unable to create stream on HGlobal
;                                       3: unable to create bitmap from stream
