Here is a small example (from @UEZ:

Here a other example I also think it is from UEZ 

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

 _GDIPlus_Startup()

$hSplashlogo = _GDIPlus_ImageLoadFromFile("C:\Program Files (x86)\AutoIt3\Examples\GUI\Torus.png")


$logoheight = (@DesktopHeight/2) - (_GDIPlus_ImageGetHeight($hSplashlogo)/2) - 50
$logowidth = (@DesktopWidth /2) - (_GDIPlus_ImageGetWidth($hSplashlogo)/2)
$SplashGUIlogo = GUICreate("", _GDIPlus_ImageGetWidth($hSplashlogo), _GDIPlus_ImageGetHeight($hSplashlogo), $logowidth, $logoheight, $WS_POPUP, BitOR($WS_EX_LAYERED,$WS_EX_TOOLWINDOW))
_SetBitmap($SplashGUIlogo, $hSplashlogo, 255, _GDIPlus_ImageGetWidth($hSplashlogo), _GDIPlus_ImageGetHeight($hSplashlogo))
GUISetState(@SW_SHOWNA, $SplashGUIlogo)


While 1
    Sleep(20)
WEnd

 _GDIPlus_Shutdown()


Func _SetBitmap($hGUI, $hImage, $iOpacity, $n_width = 200, $n_height = 200)
    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)
    $tSize = DllStructCreate($tagSIZE)

Hi Räuber @Hotzenplotz

UEZ ended before us :)
This is what I had so far, based on AutoBert's 1st post above (another script by UEZ), after having added this : 

$hGUI2 = GUICreate("GUI2", 120, 120, -1, -1, $WS_POPUP, BitOr($WS_EX_LAYERED, $WS_EX_MDICHILD), $hGUI)
GUISetBkColor( 0xABCDEF, $hGUI2) ; transparent
_WinAPI_SetLayeredWindowAttributes($hGUI2, 0xABCDEF)
GUICtrlCreateLabel("HELLO THERE", 60, 12, 60, 60)
GUICtrlSetColor(-1, 0xFFFF00) ; yellow
GUICtrlSetFont(-1, 10, 600)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

582580920_pnglabelintransparentgui.png.733804fda88e961d6996fb24d733fc44.png

@UEZ : could you please explain BitOR($WS_POPUP, $WS_CHILD) in your script ?
I always read that these two shouldn't be found together, also it seems to work with $WS_POPUP only.
Thanks !

This is a leftover from the coding session - can be removed as MS states: "The window is a child window. A window with this style cannot have a menu bar. This style cannot be used with the WS_POPUP style."

another question,

 

why 

this works 

$close = GUICtrlCreateButton("", 363, 622, 75,35)
GUICtrlSetOnEvent($close, "Close")
GUICtrlSetTip($close, "Ausschalten")

but if i try this with GUICtrlCreateLabel the event not is not working

seems the label must have a text to work, can i get it working without a text

@Hotzenplotz : probably because you created the label without caption, like this : 

$idLabel = GUICtrlCreateLabel("", ...)

Just add some spaces as caption ("     ", ...) using the _StringRepeat() function if you prefer, maybe add a $SS_SUNKEN style to the label during the coding session, to display a border around your label etc...

@UEZ : in your script just above, or even in your other script found in AutoBert's post at the beginning of this thread, can't we bypass the functions _SetBitmap() or _WinAPI_BitmapDisplayTransparentInGUI() and replace them with a one-liner _WinAPI_UpdateLayeredWindowEx(), like this : 

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <WinAPISysWin.au3>
#include <WindowsConstants.au3>

Global Const $SC_DRAGMOVE = 0xF012
Global $hGUI

$sFileName = @ScriptDir & "\torus.png"
If Not FileExists($sFileName) Then Exit MsgBox(0, "Exit", "Image not found")

_GDIPlus_Startup()
$hImage = _GDIPlus_BitmapCreateFromFile($sFileName)
$hBitmap = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
$iW = _GDIPlus_ImageGetWidth($hImage)
$iH = _GDIPlus_ImageGetHeight($hImage)

$hGUI = GUICreate("", $iW, $iH, -1, -1, $WS_POPUP, BitOr($WS_EX_LAYERED, $WS_EX_TOPMOST))
_WinAPI_UpdateLayeredWindowEx($hGUI, -1, -1, $hBitmap) ; <=============================

GUISetState(@SW_SHOW)
GUIRegisterMsg($WM_LBUTTONDOWN, "_WM_LBUTTONDOWN")

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

GUIDelete()
_WinAPI_DeleteObject($hBitmap)
_GDIPlus_BitmapDispose($hImage)
_GDIPlus_Shutdown()

Func _WM_LBUTTONDOWN($hWnd, $iMsg, $wParam, $lParam)
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)
EndFunc   ;==>_WM_LBUTTONDOWN

Thanks for your advice

You are right, under the hood it is the same function. I don't know each of the Winapi GDI function which Yashied has added to his famous WinAPIEx UDF. WinAPIEx UDF was added to Autoit meanwhile.

@pixelsearch thanks, some things to easy if you know them ^^

now finally i am nearly finished, but i have one annoying thing. if i start the script its an streaming radio, i put in labels to switch between favorite stations, and if i change the stations the name of it and fav numbers are shown on the script in an other label with text. the strange thing is after i start the script and i press a fav then it change the station but the label with the info stays empty until i press the fav again, then the info is shown.'

Solution found in call the guis into the fav functions

Hello,

after such a long time, the posts here have been very helpful for me today. Thanks for that.

I can now display .png files with transparency. My question about this:

Can I also display a transparent png scaled? I want it to scale proportionally to the resolution (or number of pixels).
That shouldn't be a problem if I could even manage to scale a png in any way when displaying it.

It's easy with jpg's, but as a beginner I still don't have a solution for png's.:wacko:

If anyone wants to try it out, here is my example script, which I adapted
from the examples above for this purpose without knowing much about it: 2in1 (haha).au3

I've simplified my question here:D:

how.jpg

PNG1.png

PNG2.png

2in1 (haha).au3
