Currently no you can't,

But yes you could do it using GDI+ and file reading.

You would first need to read the APNG data chuncks so you can feed GDI+ the correct frame data.

It would take a little effort, but it would be fully possible from the APNG specifications I just read.

This seems a trick, but works:

; Animated Gif
; Author - gafrost

Opt("MustDeclareVars", 1)
#include <IE.au3>

_Main()

Func _Main()
    Local $pheight = 50, $pwidth = 50, $oIE, $GUIActiveX, $gif
    $gif = FileOpenDialog("Select Animated Gif", @ScriptDir, "gif files (*.gif)", 3)
    If @error Then Exit
    _GetGifPixWidth_Height($gif, $pwidth, $pheight)
    $oIE = ObjCreate("Shell.Explorer.2")
    GUICreate("Embedded Web control Test", 640, 580)
    $GUIActiveX = GUICtrlCreateObj($oIE, 0, 0, $pwidth, $pheight)
    $oIE.navigate ("about:blank")
    While _IEPropertyGet($oIE, "busy")
        Sleep(100)
    WEnd
    $oIE.document.body.background = $gif
    $oIE.document.body.scroll = "no"
    GUISetState()
    While GUIGetMsg() <> -3
    WEnd
EndFunc   ;==>_Main

Func _GetGifPixWidth_Height($s_gif, ByRef $pwidth, ByRef $pheight)
    If FileGetSize($s_gif) > 9 Then
        Local $sizes = FileRead($s_gif, 10)
        ConsoleWrite("Gif version: " & StringMid($sizes, 1, 6) & @LF)
        $pwidth = Asc(StringMid($sizes, 8, 1)) * 256 + Asc(StringMid($sizes, 7, 1))
        $pheight = Asc(StringMid($sizes, 10, 1)) * 256 + Asc(StringMid($sizes, 9, 1))
        ConsoleWrite($pwidth & " x " & $pheight & @LF)
    EndIf
EndFunc   ;==>_GetGifPixWidth_Height

So you disappear for NINE months and when you come back you tell us you didn't spend the slightest effort to do anything yourself? You must be the laziest man alive.

Anyway, to read files you use FileRead(). To decode it into something useful, read about the technical details in the Wikipedia article you stole that image from.
