Thanks for the link, there example work but when I tried to make work for my script don't work. What I do wrong?

#include <GDIPlus.au3>

_GDIPlus_Startup()
$MAIN = GUICreate("Europe Map",387,371)
$GRAPHIC = _GDIPlus_GraphicsCreateFromHWND($MAIN)
GUISetState(@SW_SHOW,$MAIN)

DrawMap($GRAPHIC,@ScriptDir & "\Europe.bmp")
FillArea($GRAPHIC,10,10,0xFF8000)

While True
    Switch GUIGetMsg()
        Case -3
            _GDIPlus_GraphicsDispose($GRAPHIC)
            _GDIPlus_Shutdown()
            Exit
    EndSwitch
    Sleep(10)
WEnd

Func DrawMap($GRAPHIC,$PATH)
    Local $IMG = _GDIPlus_ImageLoadFromFile($PATH)
    _GDIPlus_GraphicsDrawImageRect($GRAPHIC,$IMG,0,0,387,371)
    _GDIPlus_ImageDispose($IMG)
EndFunc

Func FillArea($GRAPHIC,$X,$Y,$COLOR)
    Local $DC = _GDIPlus_GraphicsGetDC($GRAPHIC)
    Local $BRUSH = _GDIPlus_BrushCreateSolid($COLOR)
    Local $OBJ = _WinAPI_SelectObject($DC,$BRUSH)
    DllCall("gdi32.dll","int","ExtFloodFill","int",$DC,"int",$X,"int",$Y,"int",PixelGetColor($X,$Y),"uint",1)
    _WinAPI_SelectObject($DC,$OBJ)
    _GDIPlus_BrushDispose($BRUSH)
EndFunc

EDIT:

It works in this way but I'm interesed if works with GDI+

$MAIN = GUICreate("Europe Map",387,371)
$MAP = GUICtrlCreatePic(@ScriptDir & "\Europe.bmp",0,0,387,371)
GUISetState(@SW_SHOW)
FillArea(ControlGetHandle($MAIN,"",$MAP),200,200,0xFF8000)

While 1
    Switch GUIGetMsg()
        Case -3
            Exit
    EndSwitch
    Sleep(10)
WEnd

Func FillArea($HWND,$X,$Y,$COLOR)
    $DC = DllCall("user32.dll","int","GetDC","hwnd",$HWND)
    $BRUSH = DllCall("gdi32.dll","long","CreateSolidBrush","int",$COLOR)
    $OBJ = DLLCall("gdi32.dll","int","SelectObject","int",$DC[0],"int",$BRUSH[0])
    DllCall("gdi32.dll","int","ExtFloodFill","int",$DC[0],"int",$X,"int",$Y,"int",0x00,"uint",0) ; border color
    DllCall("gdi32.dll","int","SelectObject","int",$DC[0],"int",$OBJ[0])
    DllCall("gdi32.dll","int","DeleteObject","int",$BRUSH[0])
EndFunc

You mean something like this?:

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#Include <Misc.au3>

Opt("GUIOnEventMode", 1)
Opt("MouseCoordMode",2)

Global $dll = DllOpen("user32.dll")

_GDIPlus_Startup()
Global $bitmap_from_file = _GDIPlus_BitmapCreateFromFile(@ScriptDir & '\Europe.bmp')

Global $width = _GDIPlus_ImageGetWidth ($bitmap_from_file)
Global $height = _GDIPlus_ImageGetHeight ($bitmap_from_file)

Global $hwnd = GUICreate("GDI32: Flood Fill Example", $width, $height)

GUISetOnEvent(-3, "Close")
GUISetState()

Global $hDC = _WinAPI_GetDC($hWnd)
Global $hGraphics = _GDIPlus_GraphicsCreateFromHDC($hDC)

_GDIPlus_GraphicsDrawImageRect($hGraphics, $bitmap_from_file, 0, 0, $width, $height)

Global $hBrush = DllCall("gdi32.dll", "long", "CreateSolidBrush", "int", 0xFF5050) ; fill color BGR
Global $obj_orig = DLLCall("gdi32.dll", "int", "SelectObject", "int", $hDC, "int", $hBrush[0])

While Sleep(50)

    If _IsPressed("01") And WinActive($hWnd) Then
        $mp = MouseGetPos()
        DllCall("gdi32.dll", "int", "FloodFill", "int", $hDC, "int", $mp[0], "int", $mp[1], "int", 0x000000)
    EndIf
WEnd

Func Close()
    DllClose($dll)
    DLLCall("gdi32.dll", "int", "SelectObject", "hwnd", $hwnd, "int", $obj_orig[0])
    DLLCall("gdi32.dll", "int", "DeleteObject", "int",$hBrush[0])
    _WinAPI_ReleaseDC($hWnd, $hDC)
    _GDIPlus_GraphicsDispose($hGraphics)
    _GDIPlus_Shutdown()
    Exit
EndFunc

Yes, finally I could create the function FillMap() as I wanted. One more question: why CreateSolidBrush() cannot create a brush with alpha channel? I tried GdipCreateSolidFill() but didn't work, any idea how can I make it work?

This is the code I have, have anyone an ideea why I cannot create a brush using GDI+ UDF with alpha channel instead of CreateSolidBrush() function?

#include <GDIPlus.au3>

_GDIPlus_Startup()
$MAIN = GUICreate("Europe Map",790,590)
$MAP = GUICtrlCreatePic(@ScriptDir & "\Europe.bmp",0,0,790,590)
GUISetState(@SW_SHOW)
FillArea(ControlGetHandle($MAIN,"",$MAP),430,215,"00FF80","AA")

While 1
    Switch GUIGetMsg()
        Case -3
            _GDIPlus_Shutdown()
            Exit
    EndSwitch
    Sleep(10)
WEnd

Func FillArea($HWND,$X,$Y,$COLOR,$ALPHA)
    $DC = DllCall("user32.dll","int","GetDC","hwnd",$HWND)
;~  $BRUSH = _GDIPlus_BrushCreateSolid('0x' & $ALPHA & $COLOR)
    $BRUSH = DllCall("gdi32.dll","long","CreateSolidBrush","int",'0x' & $COLOR)
    $OBJ = DllCall("gdi32.dll","int","SelectObject","int",$DC[0],"int",$BRUSH[0])
    DllCall("gdi32.dll","int","ExtFloodFill","int",$DC[0],"int",$X,"int",$Y,"int",0,"uint",0)
    DllCall("gdi32.dll","int","SelectObject","int",$DC[0],"int",$OBJ[0])
    DllCall("gdi32.dll","int","DeleteObject","int",$BRUSH[0])
EndFunc

My understanding is export functions from gdi32.dll use device contexts and 24 bits RGB or BGR colour format.

GDIPlus.dll export functions use handles to bitmaps and 32 bit ARGB colour format.

So I believe a 32 bit, GDIPlus brush is not compatiable, and can not be used with a 24 bit gdi32 device context of the type that is found in _WinAPI_SelectObject().

I would love to be proved wrong. Or maybe some clever work-around created by someone.
