ImageSearch of an image within an image, help please

[Yirrlaar 0]

Hello All,

I'm using "ImageSearch2015.au3" and i'm trying to figure out WHY, for the life of me, I can't find an image is hidden.

So what I came up with, is as follows:

_ImageSearchAreaHidden("C:\icon.png", 1, 0, 0, 800, 600, $x1, $y1, 80, 0)

Func _ImageSearchAreaHidden($findImage, $resultPosition, $x1, $y1, $right, $bottom, ByRef $x, ByRef $y, $tolerance, $transparency = 0)
    Local $h, $result
    local $TestScreen = "C:\TestScreen.png" ;previsous screenshot of the image looking for, fully visible
    If Not FileExists($findImage) Then Return "Image File not found"
    If $transparency <> 0 Then $findImage = "*" & $transparency & " " & $findImage
    If $tolerance < 0 Or $tolerance > 255 Then $tolerance = 0
    If $h_ImageSearchDLL = -1 Then _ImageSearchStartup()
    
    If $tolerance > 0 Then $findImage = "*" & $tolerance & " " & $findImage
    $result = DllCall($h_ImageSearchDLL, "str", "ImageSearchEx", "str", $TestScreen, "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $findImage)
    If @error Then Return "DllCall Error=" & @error
    If $result = "0" Then Return False
    $array = StringSplit($result[0], "|")
    If (UBound($array) >= 4) Then
        $x = Int(Number($array[2])) ; Get the x,y location of the match
        $y = Int(Number($array[3]))
        If $resultPosition = 1 Then
            $x = $x + Int(Number($array[4]) / 2) ; Account for the size of the image to compute the centre of search
            $y = $y + Int(Number($array[5]) / 2)
        EndIf
        Return True
    EndIf
EndFunc   ;==>_ImageSearchAreaHidden

Now when the folder with the icon is completely visible, it finds the icon without any issues, however if I cover up the icon, it no longer finds the image in the folder.

Any ideas?

Well, how will the script find something it cant see? It has to be visible, the same way for you to see something it has to be.

There is an image of the desktop that I am trying to use as a reference ... Hence 

local $TestScreen = "C:\TestScreen.png" ;previsous screenshot of the image looking for, fully visible

so if it can't see the image on the screen then reference the TestScreen.png and it that way.

It should detect the image if you feed it a previous screenshot where the image was visible, as you say you did.

I will have to do some tests at home.

I don't believe ImageSearch works on anything past the original Windows 10 Creators Update
