GDI+ Back Buffering two BitBlt calls to avoid flickering

monoscout999 · September 6, 2011

Hi forum i want to make a GUI that cause a Blur effect in the Background found a method:

superimpose two images, one original and one slightly out of phase with the original.

the idea is to do this effect in real time.

I don´t know how to remove the flickering that the two calls of BitBlt produces.. help me to find out how to deal with it,

This is the code:

#include <WinAPIEx.au3>
#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
 
HotKeySet("{Esc}", "_Exit")
 
$hForm = GUICreate('MyGUI', 200, 200, -1, -1, $WS_POPUP, $WS_EX_LAYERED)
$Pic = GUICtrlCreatePic('', 0, 0, 200, 200, -1, $GUI_WS_EX_PARENTDRAG)
$hPic = GUICtrlGetHandle($Pic)
 
GUISetBkColor(0x123456)
_WinAPI_SetLayeredWindowAttributes($hForm, 0x123456, 255, 0x01)
 
GUISetState()
 
$hDC = _WinAPI_GetDC($hPic)
$hDeskDC = _WinAPI_GetDC(0)
 
_GDIPlus_Startup()
 
$hGraphics = _GDIPlus_GraphicsCreateFromHDC($hDC)
_GDIPlus_GraphicsClear($hGraphics, 0xFF123456)
 
$hGBitmap = _GDIPlus_BitmapCreateFromGraphics(200, 200, $hGraphics)
$hGBackbuffer = _GDIPlus_ImageGetGraphicsContext($hGBitmap)
 
$hBrush = _GDIPlus_BrushCreateSolid(0xFF123456)
 
AdlibRegister("MyPaint", 100)
 
GUISetState()
 
Do
Until GUIGetMsg() = -3
 
_Exit()
 
Func MyPaint()
    $aPos = WinGetPos($hForm)
    _GDIPlus_GraphicsFillRect($hGBackbuffer, 0, 0, 200, 200, $hBrush)
    _GDIPlus_GraphicsDrawImage($hGraphics, $hGBitmap, 0, 0)
    _WinAPI_BitBlt($hDC, 0, 0, 200, 200, $hDeskDC, $aPos[0], $aPos[1], $SRCCOPY)
    _WinAPI_BitBlt($hDC, 0, 0, 200, 200, $hDeskDC, $aPos[0] - 1, $aPos[1] - 1, $SRCAND) ; To make the Blur effect
EndFunc   ;==>MyPaint
 
Func _Exit()
    _GDIPlus_BrushDispose($hBrush)
    _GDIPlus_GraphicsDispose($hGBackbuffer)
    _GDIPlus_BitmapDispose($hGBitmap)
    _GDIPlus_Shutdown()
    _WinAPI_ReleaseDC($hPic, $hDC)
    _WinAPI_ReleaseDC(0, $hDeskDC)
    Exit
EndFunc   ;==>_Exit

One theory that i have is to use a different DestDC in the first BitBlt and pass it as SrcDC in the second call, but i don´t know how to do it.

I already have many versions of this work, and this is the most promising so far. but i am open to suggestions,

Have a look at this code by Siao

it blurs the desktop, then you can use the gui as a squeegee to clean the screen

Blurring the screen

JohnOne · September 6, 2011

Tried the above siao code.

Does anyone know where the missing constants now reside

$RDW_INVALIDATE
$RDW_UPDATENOW
$RDW_ALLCHILDREN
$RDW_INVALIDATE

monoscout999 · September 6, 2011

I want to do the opposite, just like AERO do... but someone just told me that AERO use Video Card instead Windows functions to do the blur, so my chances of matching almost the performance of AERO are few..

i include WinAPIEx.au3 and it works , but where are those constants... who knows.

Cheers, probably winapiconstants.

monoscout999 · September 6, 2011

Thank you UEZ i think that i can do something with the second example.

i never knew how to use the GDI+ effect class.
