Added an example how to play a webp animation on the desktop background behind the icons -> WebP See WebP Example14.au3. You need beside the appropriate _WebP_x??.dll also "Rostislav Uzunov Animation 480x270@30FPS.webp". Exit of the script only from the taskbar yet. It is very CPU intensive.

I can only test on my Notebook with Win11 24H2 and the solution was to set parent to the WorkerW handle under Progman. I found also the information after midnight to force WorkerW under Progman using DllCall("user32.dll", "lresult", "SendMessage","hwnd", $hProgman, "uint", 0x052C, "wparam", 0, "lparam", 0) but I was too sleepy to continue. ;Code by UEZ build 2025-07-16 beta #include <WinAPI.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Global $hProgman = WinGetHandle("[CLASS:Progman]"), $hWorkerW, $i If Not $hProgman Then Exit MsgBox(16, "ERROR", "Couldn't find Progman", 30) DllCall("user32.dll", "lresult", "SendMessage","hwnd", $hProgman, "uint", 0x052C, "wparam", 0, "lparam", 0) Sleep(250) ;~ $i = 1 ;~ While True ;~ $h = WinGetHandle("[CLASS:WorkerW;INSTANCE:" & $i & "]") ;~ $hWorkerW = _WinAPI_FindWindowEx($hProgman, $h, "WorkerW") ;~ If $hWorkerW Then ExitLoop ;~ $i += 1 ;~ If $i = 100 Then Exit MsgBox(16, "ERROR", "Couldn't find WorkerW under Progman", 30) ;~ WEnd Global $hWorkerW = _WinAPI_FindWindowEx($hProgman, 0, "WorkerW", "") If $hWorkerW = 0 Then Exit MsgBox(16, "ERROR", "Couldn't find WorkerW under Progman", 30) Global $SWP = BitOR($SWP_NOMOVE, $SWP_NOSIZE, $SWP_NOACTIVATE) $hGUI = GUICreate("Overlay", 400, 300, 10, 10, $WS_POPUP, $WS_EX_TOOLWINDOW) GUICtrlCreatePic("C:\Program Files (x86)\AutoIt3\Examples\GUI\msoobe.jpg", 0, 0, 400, 300) _WinAPI_SetParent($hGUI, $hWorkerW) _WinAPI_SetWindowPos($hGUI, $HWND_BOTTOM, 0, 0, 0, 0, $SWP) _WinAPI_SetWindowLong($hGUI, $GWL_EXSTYLE, BitOR(_WinAPI_GetWindowLong($hGUI, $GWL_EXSTYLE), $WS_EX_LAYERED, $WS_EX_TRANSPARENT)) _WinAPI_SetLayeredWindowAttributes($hGUI, 0, 220, $LWA_ALPHA) GUISetState(@SW_SHOWNOACTIVATE, $hGUI) While GUIGetMsg() <> $GUI_EVENT_CLOSE WEnd Func _WinAPI_FindWindowEx($hParent, $hAfter, $sClass, $sTitle = "") Local $ret = DllCall("user32.dll", "hwnd", "FindWindowExW", "hwnd", $hParent, "hwnd", $hAfter, "wstr", $sClass, "wstr", $sTitle) If @error Or Not IsArray($ret) Then Return 0 Return $ret[0] EndFunc ;==>_WinAPI_FindWindowEx

It provides one of the WorkerW handles, not the WorkerW handle under Progman. 😉 This works for me: ;Code by UEZ build 2025-07-16 beta #include <WinAPI.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Global $hProgman = WinGetHandle("[CLASS:Progman]"), $hWorkerW, $i $i = 1 While True $h = WinGetHandle("[CLASS:WorkerW;INSTANCE:" & $i & "]") $hWorkerW = _WinAPI_FindWindowEx($hProgman, $h, "WorkerW", "") If $hWorkerW Then ExitLoop $i += 1 If $i = 100 Then Exit MsgBox(16, "ERROR", "Couldn't find WorkerW under Progman", 30) WEnd Global $SWP = BitOR($SWP_NOMOVE, $SWP_NOSIZE, $SWP_NOACTIVATE) $hGUI = GUICreate("Overlay", 400, 300, 10, 10, $WS_POPUP, $WS_EX_TOOLWINDOW) GUICtrlCreatePic("C:\Program Files (x86)\AutoIt3\Examples\GUI\msoobe.jpg", 0, 0, 400, 300) _WinAPI_SetParent($hGUI, $hWorkerW) _WinAPI_SetWindowPos($hGUI, $HWND_BOTTOM, 0,0,0,0, $SWP) _WinAPI_SetWindowLong($hGUI, $GWL_EXSTYLE, BitOR(_WinAPI_GetWindowLong($hGUI, $GWL_EXSTYLE), $WS_EX_LAYERED, $WS_EX_TRANSPARENT)) _WinAPI_SetLayeredWindowAttributes($hGUI, 0, 220, $LWA_ALPHA) GUISetState(@SW_SHOWNOACTIVATE, $hGUI) While GUIGetMsg() <> $GUI_EVENT_CLOSE WEnd Func _WinAPI_FindWindowEx($hParent, $hAfter, $sClass, $sTitle = "") Local $ret = DllCall("user32.dll", "hwnd", "FindWindowExW", "hwnd", $hParent, "hwnd", $hAfter, "wstr", $sClass, "wstr", $sTitle) If @error Or Not IsArray($ret) Then Return 0 Return $ret[0] EndFunc

I found a way in Win11 24H2 Spy++: but I couldn't find a way to get WorkerW handle by searching from Progman. I will continue tomorrow...

I assume the binary code is for x86 only.

You may use structs and define in structs arrays. With struct arrays you can use the winapi memory functions.

Hi @pixelsearch thank again for your feedback. Regarding 1) my bad. The example 08 doesn't contain a check if creation fails - it just proceeds. Easy to fix: Global $sFile = @ScriptDir & "\TestAnim.webp" Global $iResult = WebP_CreateWebPCreateAnim($aFrames, $sFile) If $iResult < 1 Or @error Then ConsoleWrite($iResult & " / " & @error & @CRLF) _GDIPlus_Shutdown() Exit MsgBox($MB_ICONERROR, "Error", "Something went wrong creating the animation!") EndIf 2) to be honest - I'm too lazy to create a GUI with all parameters. I'm not sure if all the parameters are required or will ever be needed, but I'm happy to include this as Example08.1.au3. It would only make sense if the value range per parameter was listed in the GUI. The ranges should be described in the UDF header.

Oops, forgot to remove the manual path to the DLL. Fixed.

Updated to v0.3.8 build 2025-07-04 beta added loop count parameter for the 3 animation functions. Default = 0 which is endless. added WebP_GetImagesDiffFromFile() which can compare two WebP files which same dimension

Yes, that was the reason for that line if Array is only 1D. When you display the animation, you can choose to play it one time, n times or endless but there is also an option to set loop_count. I will add it as an parameter that external players can play it accordingly. Thanks for your feedback!

Hi @pixelsearch The idea was check if array is 2D but you are right, instead of checking permanently the array, one check should be enough -> fixed. I wanted to see if delays are properly added to the animation. There no other reason to slow down the frames. 🙂
