Error when attempting to use _GDIPlus_ImageGetWidth and Height in GUICtrlCreatePic

I've used Dmitry Yudin (Lazycat)  function _ImageGetInfo to get the width and height with no issues.

I would rather use the GDIPlus width and height.  Less include files.

    Local $iImage = _ImageGetInfo($iFile)
    Local $iWidth = _ImageGetParam($iImage, "Width")
    Local $iHeight = _ImageGetParam($iImage, "Height")


    Local $iImage = _GDIPlus_ImageLoadFromFile($iFile)
    Local $iWidth = _GDIPlus_ImageGetWidth($iImage)  
    Local $iHeight = _GDIPlus_ImageGetHeight($iImage)

    $gHWnd = GUICreate("", $iWidth, $iHeight, -1, -1, 0x80000000)
    GUISetState()
    GUICtrlCreatePic($iFile, 0, 0, $iWidth, $iHeight)

    $hGraphic = _GDIPlus_GraphicsCreateFromHWND($gHWnd)
    _GDIPlus_GraphicsDrawImageRect($hGraphic, $iImage, 0, 0, $iWidth, $iHeight)

GDIPlus requires more code and has no handle to pass into my Fade function using WinSetTrans

This works for me :

#include <GDIPlus.au3>

_GDIPlus_Startup()

Local $sFile   = StringRegExpReplace(@AutoItExe, "(?i)AutoIt3.exe$", "") & "Examples\GUI\Merlin.gif"
Local $hImage  = _GDIPlus_ImageLoadFromFile($sFile)
Local $iWidth  = _GDIPlus_ImageGetWidth($hImage)
Local $iHeight = _GDIPlus_ImageGetHeight($hImage)

$gHWnd = GUICreate("", $iWidth, $iHeight, -1, -1, 0x80000000)
GUISetState()
GUICtrlCreatePic($sFile, 0, 0, $iWidth, $iHeight)

$hGraphic = _GDIPlus_GraphicsCreateFromHWND($gHWnd)
_GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage, 0, 0, $iWidth, $iHeight)

Sleep(2000)

_GDIPlus_ImageDispose($hImage)
_GDIPlus_Shutdown()
GUIDelete($gHWnd)

(Edit) @BackHomeAgain

What error message appears in your SciTE console ?

I copied your example code as is and ran the script. 

_GDIPlus_GraphicsDrawImageRect worked fine.

GUICtrlCreatePic failed. 

"0" if picture cannot be created.

Sorry  I didn't  get back to you sooner.  Trying to figure out what's going on.

Hi Nine !

Unfortunately, I don't know if this is a problem with .gif files at all. The OP has neither specified a file type nor attached a file. So I just took a file from the ..\Examples\GUI\ folder (merlin.gif) to make sure that it exists.

@BackHomeAgain :

You are right, GUICtrlCreatePic returns 0 ("picture cannot be created"). I didn't notice that, since the picture appears. I found the following thread, in which you participated yourself, by the way ;) why-guictrlcreatepic-doesnt-work-after-_gdiplus_startup

@UEZ : It doesn't work, because _GDIPlus_ImageLoadFromFile($file) is locking the file and GUICtrlCreatePic() cannot load it because it is locked by GDI+ function.
