Transparent Window with PNG?

[hmes]

So i know how to put PNG file on GUI

But i want it to display only PNG file, without GUI frame, X button, minimalize button or white background

Any suggestions?

Hi hmes!

What have you tried so far?

Sugestion: advanced search > search only title > png gui

Try this

expandcollapse popup

#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
Dim $_GuiDelete

$_PngUrl = 'http://www.uclouvain.be/cps/ucl/doc/adcp/images/Google_logo.png'
$_PngPath = @TempDir & "\temp1.png"
If Not FileExists ( $_PngPath ) Then InetGet ( $_PngUrl, $_PngPath, 1 )
_GDIPlus_Startup ( )
$_Image = _GDIPlus_ImageLoadFromFile ( $_PngPath )
$_Width = _GDIPlus_ImageGetWidth ( $_Image )
$_Height = _GDIPlus_ImageGetHeight ( $_Image )
$_Ratio = $_Width / $_Height
$_Width = 600  
$_Gui = GUICreate ( "gui", $_Width , $_Width / $_Ratio, -1, -1, -1, BitOR ( $WS_EX_LAYERED, $WS_EX_TOPMOST ) )
$_Image = _ImageResize ( $_PngPath, $_Width, $_Width / $_Ratio ) 
_SetBitMap ( $_Gui, $_Image, 255, $_Width, $_Width / $_Ratio )
GUISetState ( @SW_SHOW )

While 1

Hi this is exactly what I'm looknig for and it works great, but do you know if it's possible to allow the gui to be moved (with mouse).

Actually I'm looking for something like a floating icon always on top (with action on left click and possibility to be moved).

This script does the trick (I can catch up the primary button with $GUI_EVENT_PRIMARYUP) but I don't know how to move the gui..

Can you help me please?

Thank you in advance.
