ImageSearch DLL error return problem

[Mbee]

So I've been able to use some version of ImageSearch.au3 (author unknown) and some version of ImageSearchDLL.dll in the past, but trying again now I find I am very confused. First, which set should I choose? Here's the header and some code from the first part of the version of ImageSearch.au3 I have, in case anyone can identify it...

#include-once
; ------------------------------------------------------------------------------
;
; AutoIt Version: 3.0
; Language:       English
; Description:    Functions that assist with Image Search
;                 Require that the ImageSearchDLL.dll be loadable
;
; ------------------------------------------------------------------------------

;===============================================================================
;
; Description:      Find the position of an image on the desktop
; Syntax:           _ImageSearchArea, _ImageSearch
; Parameter(s):
;                   $findImage - the image to locate on the desktop
;                   $tolerance - 0 for no tolerance (0-255). Needed when colors of
;                                image differ from desktop. e.g GIF
;                   $resultPosition - Set where the returned x,y location of the image is.
;                                     1 for centre of image, 0 for top left of image
;                   $x $y - Return the x and y location of the image
;
; Return Value(s):  On Success - Returns 1
;                   On Failure - Returns 0
;
; Note: Use _ImageSearch to search the entire desktop, _ImageSearchArea to specify
;       a desktop region to search
;
;===============================================================================
Func _ImageSearch($findImage, $resultPosition, ByRef $x, ByRef $y,$tolerance, $HBMP=0)
   return _ImageSearchArea($findImage,$resultPosition,0,0,@DesktopWidth,@DesktopHeight,$x,$y,$tolerance,$HBMP)
EndFunc


Func _ImageSearchArea($findImage, $resultPosition, $x1, $y1, $arg_right, $bottom, ByRef $x, ByRef $y, $tolerance, $HBMP=0)
    ;MsgBox(0,"asd","" & $x1 & " " & $y1 & " " & $right & " " & $bottom)
    if $tolerance>0 then $findImage = "*" & $tolerance & " " & $findImage
    Local $right = $arg_right
If IsString($findImage) Then
    Local $result = DllCall("ImageSearchDLL.dll", "str", "ImageSearch", "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $findImage, "ptr", $HBMP)
Else
    Local $result = DllCall("ImageSearchDLL.dll", "str", "ImageSearch", "int", $x1, "int", $y1, "int", $right, "int", $bottom, "ptr", $findImage, "ptr", $HBMP)
EndIf

    ; If error exit
    if $result[0]="0" then return 0

    ; Otherwise get the x,y location of the match and the size of the image to
    ; compute the centre of search
    Local $array = StringSplit($result[0],"|")

   $x=Int(Number($array[2]))
   $y=Int(Number($array[3]))
   if $resultPosition=1 then
      $x=$x + Int(Number($array[4])/2)
      $y=$y + Int(Number($array[5])/2)
   endif
   return 1
EndFunc

My problem is with the error return processing ("if $result[0]="0" then return 0"), which causes the latest version of AutoIt x64 to complain that the $result variable is not an array / subscript invalid.  My hunch is that the .au3 file and the .dll are not compatible, but I don't know what to do about it.

My need is to to see if a particular area within a desktop window looks like scenario 1 or scenario 2.

Would someone be able to help me, please?

I've used this as well, and I know that I've found several versions, so the easiest thing to do is provide what I've been using (attached).

I mainly have used the _ImageSearchArea part, with transparency, and a call with it for me usually looks like this:

Local $sFile = 'image.png' ; Path to the image file, we dont need to open it or get a handle or anything first
Local $aRange[] = [4, 100, 100, 300, 300] ; Area to search, x1, y1, x2, y2
Local $aCoords[2] ; Resulting location of the found image, either top left or center of image based on second parameter
Local $iShade = 10 ; 10 'shades' of variance, useful if the image is saved with compression, for example
Local $sTrans = "0xFF0000" ; Red in the image is 'transparent', and isnt used in the image comparison. Useful if a section of the image could be different on each check
Local $bIS

$bIS = _ImageSearchArea($sFile, 1, $aRange[1], $aRange[2], $aRange[3], $aRange[4], $aCoords[0], $aCoords[1], $iShade, $sTrans)

If $bIS Then
    ; Do the thing
EndIf

I currently use this in Windows 10 without a problem, and I believe that it's run as 32 bit, so not sure how the 64 bit performs. I haven't really ever had any issues with using it. Let me know if you want more of an explanation or full example.
