transparent : non transparent

[kopernic]

I have following problem

PrintScreen button captures desktop with app window visible.

Capture with Print Screen

AutoIT seems not to see anything inside this window - PixelGetColor returns a color of the background (or some icon if it is in a way).

Capture captures clear desktop.

Autoit capture

CaptureWindow captures a part of a desktop covered with window.

Is there any workaround or am I doing somethin wrong??

To see what's wrong you should post your code.

code is veeery basic

#Include <ScreenCapture.au3>
Run("C:\Program Files\xxx.exe","C:\Program Files\xxx")
sleep(10000)
_ScreenCapture_Capture(@MyDocumentsDir & "\GDIPlus_Image1.jpg")
sleep(1000)
_ScreenCapture_CaptureWnd(@MyDocumentsDir & "\GDIPlus_Image2.jpg",WinGetHandle("xxx"))

Hmm,

this is working for me:

AutoItSetOption("WinTitleMatchMode", 4)
#Include <ScreenCapture.au3>
$pid = Run(@SystemDir & "\mspaint.exe")
sleep(2000)
_ScreenCapture_Capture(@ScriptDir & "\Screenshot_full.jpg")
sleep(1000)
_ScreenCapture_CaptureWnd(@ScriptDir & "\Screenshot_window.jpg", WinGetHandle("classname=MSPaintApp"))
ProcessClose($pid)
Exit

Tested on Vista x32.

I believe that this could be caused by this specific app - MTGO launcher (exec. name: renamer.exe)

Capture and getpixelcolor work for other "regular" apps like paint or firefox.

No trace of such a problem on google. I thik that somehow app window must be rendered directly into display device, in "empty" window area. Empty=only size, position etc but no content at all...

Any idea?

I think what kopernic is trying to say is that when you do a screen capture with GDI+, windows that have a transparency value are not captured

I managed to capture an active layered window with this script.

Pressing Alt+"p" captures the active window.

expandcollapse popup

#include <GDIPlus.au3>
#include <ClipBoard.au3>

; http://www.autoitscript.com/forum/index.php?showtopic=115672&view=findpost&p=807792
HotKeySet("p", "Ps")
HotKeySet("!p", "AltPS") ;Shift-Alt-d
HotKeySet("{ESC}", "Terminate")

While 1
    Sleep(10)
WEnd

Func Ps()
    Send("{PRINTSCREEN}") ; Screen
    _Main()
    ShellExecute(@ScriptDir & "\Image.jpg")
EndFunc ;==>Ps

Func AltPS()
    Send("!{PRINTSCREEN}") ; window
    _Main()
    ShellExecute(@ScriptDir & "\Image.jpg")
EndFunc ;==>AltPS

Func Terminate()
    Exit 0
EndFunc ;==>Terminate

Func _Main()
    Local $hBmp, $hImage

    If Not _ClipBoard_Open(0) Then _WinAPI_ShowError("_ClipBoard_Open failed")
    $hBmp = _ClipBoard_GetDataEx($CF_BITMAP)
    _GDIPlus_Startup()
    $hImage = _GDIPlus_BitmapCreateFromHBITMAP($hBmp)

    ; Save bitmap to file
    _GDIPlus_ImageSaveToFile($hImage, @ScriptDir & "\Image.jpg") ;$sNewName)

    _GDIPlus_BitmapDispose($hImage)
    _GDIPlus_Shutdown()
    _ClipBoard_Close()

EndFunc ;==>_Main

That's clever Malkey

[kopernic]

... and it surely works, as I'm getting some bitmap to work on.

But

it still is not enough to use basic functions like pixelGetColor, pixelChecksum or pixelSearch.

Is there any workaround?
