Transparent Background picture

[Dieuz]

Here's my problem: I edited a .gif picture to make a transparent background (with photoshop). When I try to add this picutre into my gui, it make the background of my picture White! I dont want any background on my picture. I just want the red circle alone with nothing around it. How can I set the background of my picture transparent (so the background will have the same color as the gui background)?

SEE ATTACHED FILE

As you can see the picture have an transparent background but when I add it into my gui, it doesnt look transparent

#include <GuiConstants.au3>

GuiCreate("Picture", 200, 250,-1, -1 )

$picture = GuiCtrlCreatePic(@ScriptDir & "\Images\bille1.gif", 100,185,0,0)
GUICtrlSetBkColor($picture, $GUI_BKCOLOR_TRANSPARENT)

GuiSetState()
While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit

That doesnt work If I use $WS_EX_LAYERED, it make the background of my picture invisible and I can see through the window and I dont want that. I just want to see the background of my gui window.

Helpfile - GUICtrlCreatePic()

To have a transparent picture it is needed to use a .gif image with the transparency color set and to create the window with WS_EX_LAYERED extended style. See example 2.

I tried this EXACTLY and the background of my picture become invisible and I can see through the windows. I dont want to be able to see through the window I just want the white to disseapear. Try it by yourself with the code I have you.

This works. Mostly copied from the help file. The help file example illustrates two GUIs.

#include <GUIConstants.au3>

$gui=GUICreate("test transparentpic", 200, 250)
$pic=GUICreate("", 200, 250, 0, 0,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD),$gui)
GUICtrlCreatePic(@ScriptDir & "\bille1.gif", 100,185,0,0)

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

While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit

A tip about the help file: take the example and modify it bit by bit until it suits your needs. When your changes break it, undo and find out why. The opposite is copying and pasting the one line you think you need, and they copying and pasting more when it doesn't work - I think that's much harder.

Yep that work fine If I have only 1 picture but in my Gui I have multiples picture and when I use $WS_EX_LAYERED, every white colors on my pictures become transparent but I just want this setting for 1 picture. The $WS_EX_LAYERED is applied to all the window but how can I set it for only one picture?

Make your LAYERED inner GUI window with size of your picture (instead of size main GUI window)

I was wanting to do the same thing the OP wants but i want to also make it transparent. Why does it not work when I put in the $WS_EX_TRANSPARENT like below?

#include <GUIConstants.au3>

$gui=GUICreate("test transparentpic", 200, 250)
$pic=GUICreate("", 200, 250, 0, 0,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD,$WS_EX_TRANSPARENT),$gui)
GUICtrlCreatePic(@ScriptDir & "\bille1.gif",100,185,0,0)
WinSetTrans ( $pic, "", 50 )

GUISetState(@SW_SHOW,$pic)
Sleep(1e9)
GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
    Case $msg = $GUI_EVENT_CLOSE
        ExitLoop
    Case Else

    EndSelect
WEnd
Exit

Are you able to make it transparent and without the white background together?

Thanks,

Mason

Try this:
 

#include <GUIConstants.au3>
#include <GDIPlus.au3>
Global Const $STM_SETIMAGE = 0x0172
_GDIPlus_Startup()
$himg=_GDIPlus_ImageLoadFromFile("c:\Program Files (x86)\AutoIt3\Examples\GUI\Merlin.gif")
$hbmp=_GDIPlus_BitmapCreateHBITMAPFromBitmap($himg)
_GDIPlus_ImageDispose($himg)
$gui=GUICreate("test transparentpic", 200, 250)
$pic=GUICtrlCreatePic("",60,85,68,71)
_WinAPI_DeleteObject(GUICtrlSendMsg($pic,$STM_SETIMAGE,$IMAGE_BITMAP,$hbmp))
GUISetState(@SW_SHOW,$gui)

While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            _WinAPI_DeleteObject($hbmp)
            _GDIPlus_Shutdown()
        ExitLoop
    EndSelect
WEnd
Exit

MasonMill,

This thread is nearly 7 years old - please do not necro-post this far back again. We do not encourage it because AutoIt has changed enormously since then and it is very unlikely the problem and/or code are still relevant today. We much prefer that you start a new thread and link to the old one if necessary.

Sure...  Please go somewhere else moaning instead of necro posting in old threads. 

.. and think before you reply or post again in our forums as the next post like this gets your ass banned.
