Multiple Images search

6 posts in this topic

Hi all

i think that everyone knows the ImageSearch UDF. When there are multiple equal images it's possible to have an array of the cordinates?

And it is possible to find who is the closest to a point?

Thanks in advance and sorry for my bad english  o:)

it has a long running time? the script must be fast

i resolved the "which is the closest" problem, i have divided the screen into 5 areas one inside of the others taking as a reference the center of the screen

I did a "what is closest to my mouse" for pixelsearch.

You may be able to incorporate the same kind of idea for image search.

Func _PixelSearchRange($iSearchColor, $iRange = 50, $iExpandRate = 200, $iExpandCountMax = 10)

    Local $aPix

    ; Get mouse position
    Local $aPOS = MouseGetPos()
    If @error Then Return SetError(1, 0, "") ; Return empty string - there will be no array to return
    ; Determine initial search area
    Local $iLeft = $aPOS[0] - $iRange
    Local $iTop = $aPOS[1] - $iRange
    Local $iRight = $aPOS[0] + $iRange
    Local $iBottom = $aPOS[1] + $iRange
    ; Set expansion counter
    Local $iExpandCount = 0
    ; Start looping
    While 1
        ; Search for colour
        $aPix = PixelSearch($iLeft, $iTop, $iRight, $iBottom, $iSearchColor)
        ; Check for error
        If @error Then
            ; Colour not found so...
            ; Increase counter
            $iExpandCount += 1
            ; Return error if counter maximum reached
            If $iExpandCount > $iExpandCountMax Then Return SetError(2, 0, $aPOS) ; Or you could return $aPOS
            ; Increase search area
            $iTop -= $iExpandRate
            $iLeft -= $iExpandRate
            $iRight += $iExpandRate
            $iBottom += $iExpandRate
        Else
            ; Colour found so return coords
            Return $aPix
        EndIf
        ; Only get here if we need another expansion, so loop and search again
    WEnd

EndFunc

Did you ever make any progress with this?  I am also looking for a way to get an array of multiple images.
