Je suis sur un projet, et j'ai créé une GUI PNG, du style "Alpha Blend". Voilà mon code :
Code : Tout sélectionner
#include <GDIPlus.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <StaticConstants.au3>
Global Const $AC_SRC_ALPHA = 1
Global $hGUI1, $hGUI2, $iLabel1, $iLabel2, $iSlider, $hImage
$hGUI2 = GUICreate("Red Tool", 400, 400, -1, -1, -1, $WS_EX_LAYERED, $hGUI1)
; Create GUI
GUISetState()
; Load layered image
_GDIPlus_Startup()
$hImage = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\fond.png")
SetBitMap($hGUI2, $hImage, 255)
GUIRegisterMsg($WM_NCHITTEST, "WM_NCHITTEST")
GUISetState()
; Loop until user exits
do
until GUIGetMsg() =$GUI_EVENT_CLOSE
Func WM_NCHITTEST($hWnd, $iMsg, $iwParam, $ilParam)
if ($hWnd = $hGUI2) and ($iMsg = $WM_NCHITTEST) then Return $HTCAPTION
EndFunc
; Release resources
_GDIPlus_ImageDispose($hImage)
_GDIPlus_Shutdown()

Func SetBitmap($hGUI, $hImage, $iOpacity)
Local $hScrDC, $hMemDC, $hBitmap, $hOld, $pSize, $tSize, $pSource, $tSource, $pBlend, $tBlend
$hScrDC = _WinAPI_GetDC(0)
$hMemDC = _WinAPI_CreateCompatibleDC($hScrDC)
$hBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
$hOld = _WinAPI_SelectObject($hMemDC, $hBitmap)

_WinAPI_DeleteDC ($hMemDC)
EndFunc
