ImageSearch Usage Explanation

[MrShady187]

Hello all,

 

I have a problem I can't solve by myself 😕

I'm using ImageSearch since years and never had problems, a few weeks ago I resintalled my windows and today AutoIT + SciTE.

Now ImageSearch don't work for me anymore, even the old scripts which worked fine.

I'm using the same windows as before, just reinstalled it.

I get this Error:

"E:\Programs\AutoIt3\Include\ImageSearch.au3" (40) : ==> Subscript used on non-accessible variable.:
if $result[0]="0" then return 0
if $result^ ERROR

Is there anything I have to do before I can use it, like registering the .dll? I tried regsvr32, but I get an error.

The .au3 and .dll are in "E:\Programs\AutoIt3\Include\" and I also tried to copy in the dir where my script is.

I tried the 32- and 64-bit versionof ImageSearch, I also reinstalled AutoIt with 32/64 option.

I also tried a reworked version of ImageSearch:

With:

; Error checking goes here
If (IsArray($result) = False) Then Return 0
; If error exit
if $result[0]="0" then return 0

Instead:

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

Thats line 39/40 at the original .au3

With this version I don't get any error, but it still cannot find any image.

I also tried higher tolerance like 1000 and I tried jpg and bmp.

I also tried to install AutoIT on 😄 instead of E: and I restarted PC after install.

I tried it from SciTE (F5) and I compiled it as 32 and 64 version, but nothing works 😕

Here is the code I used to try (but I tested with an old script, what works earlier).

            MsgBox(4096, "Info", "Pic found")
        Else
            Sleep($Del1)
            ;MsgBox(4096, "Info", "Pic not found")
        EndIf
    WEnd

Func Pause()        ;F10
    $Paused = Not $Paused
    While $Paused
        ToolTip("Paused..." &@CRLF & "F1 to start testing..." &@CRLF & "F11 to exit...", 0, 0)
        Sleep(1000)
    WEnd
EndFunc

Func Exit_Sc()      ;F11
    exit 0
EndFunc

 

Do someone have any idea what's wrong??

Thank you all and best regards.

I have Autoit 32 bit.

Copy .dll to Program Files (x84)\autoie3\ and Windows\system32

Copy .au3 to Include

Hi, if you have problems with ImageSearch, try to use au3 from this link

The one from this thread is not working for me as well, but the one from link i have pasted works fine (with dll in both system32 and script dir).

Hello,

i have one issue, where maybe someone knows how i can solve it.

The program with imagsearch does work totaly well on one notebook, if i try to run it on another notebook, it does not find the pictures.

I did the same grafic resolution on both notebooks, and i did also have an eye on that scaling is the same amount.

if i do new screenshots on the 2nd notebook it does also work. But i dont wanna do the hole work with the pictures on every client.

My tolerance at imagesearch is 100.

 

Some1 any thoughts?

[Nick3399]

Hi all, I am having some trouble with imagesearch returning coordinates for client when I have called that out with AutoItSetOption for PixelCoordMode.

 

 

I have the below set at the top

AutoItSetOption("MouseCoordMode", 2)
AutoItSetOption("PixelCoordMode", 2)
AutoItSetOption("CaretCoordMode", 2)

 

and imagesearch as :

        $T22= _ImageSearch("Images\T22.png", 0, $x3, $y3, 40)
    If $T22= 1 Then
            MouseClick("left", $X3, $y3)

 

 

my client location is at 100,100 so when I am trying to click, X3 and Y3 are both +100 because it’s returning the screen coordinates

You serious think this is a good question when you reread it and expect a proper answer?

on top of that you decided to cross post and new topic yourself....   the next time please simply post one time with all the details!

can u change direction of searching to from bottom right to top left ?

[wwilk]

Hello

Heres my simple code: 

#include "_ImageSearch_UDF.au3"

Local $path = @ScriptDir & "\Data\Images" & "\chest.png"
Local $imagesearch = _ImageSearch($path,100,True)

if FileExists($path) Then
    MsgBox(0, "", $imagesearch[1])
Endif

MouseMove($imagesearch[1], $imagesearch[2],5)

and im having this type of error:

+ DllCall: C:\Users\Wilq\AppData\Local\ImageSearchUDF\ImageSearchDLL_MTXP.dll
! Search not found !

I've downloaded the ImageSearch UDF file from the AutoIt forum and placed the ImageSearch UDF file in the AutoIt "Include" directory.

Its strange but example sripts are working but when im trying to run my code it is not.

Appreciate for any help or hint

It's not an error, it says that no found!
You are using png instead of bmp. Take a screenshot and crop it where you want to find it and save it in bmp format.

Hey guys,

For those who would need it, here is an updated package which allows image searching using transparency, fixing previous bugs and including an easy example.

Usage: open the search.bmp image, run the script and it will use imagesearch to find the red square on your screen and move your mouse cursor in the middle of the square.

This gives you an easy example on how to find an image (in this example, a red square) using a transparency setting (in this case, using white as the transparency color).

Note that this only works if the image you are searching for (so the red square in this example) is not having transparent pixels itself. 

Some images have what is called an alpha channel mask, which means each pixel has an RGB value but also an alpha channel value which describes the transparency setting of this specific pixel. 
In this case since the ImageSearch transparency feature does not deal with alpha channel masks, it's impossible to find such an image using it. You'll need something more sophisticated

I face an Issue with the library. 

I have taken a screenshot from a Button and search for it. 

Func checkForImage()
    Local $search = _ImageSearch('images\previewbutton4.bmp', 1, $x, $y, 80)
    If $search = 1 Then
        MouseMove($x+20, $y+40, 2)
    EndIf
EndFunc

the button is found when i open the BMP or the screenshot tool. 
It is NOT found in the application on my screen here at home. At work, all was good and it found the image. I took a new screenshot of the Button but I am not able to make it work 

I have at home 2 Screens (Main screen is identical in model and resolution) and at work 3 Screens. 
I cant figure out why i cant get it to work at home. 
I thought retaking the screenshot would solve the issue but nah. 

Any idea how to move forward?

The posted script won't work indeed, so maybe start with posting something that is really used we could look at?  

[derocco777]

Sorry was on holiday. 
What is the issue with the snippet? 


This is the whole script where i tested the image search: 

 

#include <Array.au3>
#include <File.au3>
#include <MsgBoxConstants.au3>
#include <ImageSearch2023.au3>


global $y = 0, $x = 0

For $i = 1 to 3000
        checkForImage()
        sleep(1200)
next
    

Func checkForImage()
    Local $search = _ImageSearch('images\previewbutton4.bmp', 1, $x, $y, 80)
    If $search = 1 Then
        MouseMove($x+20, $y+40, 2)
    EndIf
EndFunc

while 1
sleep(200)
WEnd

Issue is still there. In the application the button is not recognized. 
Any ide how to solve this would be highly appreciated.
