Single transparent color with GUICtrlCreatePic?

[magician13134]

I would like to use a GIF image that has transparent parts without converting the white to transparent... I made it in Photoshop, so there's defined transparent parts, and also white parts, but when I display it, both white and transparent show up as transparent

Actually, is it possible to use a transparent PNG as a control? I know you can set it to be the background of a layered GUI, but can I just make one a picture control? Thanks

Nevermind, a little digging got me the answer

------------------

I'm using this example, but it's stretching my images and there's no option to set size, GUICtrlSetPos doesn't work either...

#include <GDIPlus.au3>
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>

Opt("MustDeclareVars", 1)

Global $hGUI, $hImage, $hGraphic

; Create GUI
$hGUI = GUICreate("Show PNG", 69, 59, -1, -1, $WS_POPUP)
GUISetState()

; Load PNG image
_GDIPlus_StartUp()
$hImage   = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\Images\nav.png")

; Draw PNG image
$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
 _GDIPlus_GraphicsDrawImage($hGraphic, $hImage, 0, 0)


; Loop until user exits
do
until GUIGetMsg() = $GUI_EVENT_CLOSE

; Clean up resources
_GDIPlus_GraphicsDispose($hGraphic)
_GDIPlus_ImageDispose($hImage)
_GDIPlus_ShutDown()

The image is 69x59px at 72dpi resolution, and it's getting cut off on both the left and the bottom... Does anyone know why that is?
