Search for larry and bmp2rgn or look here.

; EXAMPLE SHOWING Bitmap to Region function ( BMP2RGN() )
; int BMP2RGN("str","path to BMP",
;    "int",red value,
;    "int",green value,
;    "int",blue value)
; The red, green, blue values should be the color of the pixel
; in the BMP that you DON't want to see.

#include <GUIConstants.au3>
$gui = GUICreate("",127,136,-1,-1,$WS_POPUP)

$a = DLLCall(".\BMP2RGN.dll","int","BMP2RGN", "str",".\larry.bmp", "int",0, "int",0, "int",0)

SetWindowRgn($gui, $a[0])


Func SetWindowRgn($h_win, $rgn)

There are many tools to draw this picture.

For example free from Microsoft paint.NET:

It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. An active and growing online community provides friendly help, tutorials, and plugins.


There is forum of Paint.NET and dicussion about the subject

first convert it to a .gif (e.g. ms paint).

then you make a child window with the $WS_POPUP,$WS_EX_LAYERED style of the same size as the image and put only this picture as a pic control in it.

this should be all.

then you can move the child window inside the parent and the white space is transparent.

imo it is not possible without the extra child window.

style = $WS_POPUP,

ex_style = $WS_EX_LAYERED
