Gif Transparency And Winsettrans Won't Work Together

[b8bboi]

I modified the code from the GuiCtrlCreatePic example to get WinSetTrans to work with a transparent GIF.

;----- example 2
#include "GUIConstants.au3"

$gui=GUICreate("test transparentpic", 200, 100)
$pic=GUICreate("", 68, 71, 10, 10,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD),$gui)
GUICtrlCreatePic(@Systemdir & "\oobe\images\merlin.gif",0,0, 0,0)

GUISetState(@SW_SHOW,$pic)
GUISetState(@SW_SHOW,$gui)

HotKeySet("{ESC}", "main")
HotKeySet("{LEFT}", "left")
HotKeySet("{RIGHT}", "right")
HotKeySet("{DOWN}", "down")
HotKeySet("{UP}", "up")
$picPos = WinGetPos($pic)
$guiPos = WinGetPos($gui)

WinSetTrans($pic, "", 120)

do
    $msg = GUIGetMsg()
until $msg = $GUI_EVENT_CLOSE
Exit

Func main()
    $guiPos = WinGetPos($gui)
    WinMove($gui,"",$guiPos[0]+10,$guiPos[1]+10)
EndFunc

Func left ()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0]-10,$picPos[1])
EndFunc

Func right()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0]+10,$picPos[1])
EndFunc

Func down()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1]+10)
EndFunc

Func up()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1]-10)
EndFunc

Notice line 19 which is what I added.

WinSetTrans($pic, "", 120)

This didn't work. There's a white background around the GIF. However, as soon as I comment out line 19, the background will go away and the transparent GIF works again.

It's one thing or the other.

Does anyone know why?

Thanks.

Gremlins?

Try to use

GUICtrlSetState($pic, $GUI_DISABLE)
WinSetTrans($pic, "", 120)

I don't know if that will work though.

Edit:

Had the wrong function call.

Try this:

$Gui = GUICreate('Test', 300, 300, 300, 300, $WS_POPUP, $WS_EX_LAYERED+$WS_EX_TOPMOST )
    $BG = GUICtrlCreatePic('AllTrans.gif', 0, 0, 300, 300, 0)

You have to create a transparent gif named AllTrans.gif (or something).

The second line will set this transparent gif as the background-picture. Don't forget the ...,0), since this puts the image behind the other gif-pictures. Otherwise, they would not be 'clickable'.

gafrost, I tried that and it didn't work. I still get the white background.

I guess this is just a limitation of WinSetTrans.

Stands to reason that WinSetTrans() is not concentrating on your pic but on the total region that your calling?

The code I posted doesn't have winsettrans in it, and it works. (need beta)

gets rid of the background, pic itself is not transparent tho.
