Image Search Library

Recommended Posts

If anyone wants to use this in C#, here is how I did it:

    class ImageHelper
    {
        [DllImport("ImageSearchDLL.dll.32bit")] //or 64bit as you choose
        private static extern IntPtr ImageSearch(int x, int y, int right, int bottom, [MarshalAs(UnmanagedType.LPStr)]string imagePath)
 

...and then later on
 
            IntPtr result = ImageSearch(top, left, right, bottom, imagepath);
            String res = Marshal.PtrToStringAnsi(result);


            if (res[0] == '0') return null;//not found

            String[] data = res.Split('|');

            //0->found, 1->x, 2->y, 3->image width, 4->image heigth
            resX = int.Parse(data[1]);
            resY = int.Parse(data[2]);

I have tried for the past few days, but cannot get this working.

I've isolated my code to literally just look for a black square of pixels on my black desktop background, but it always returns 0. (no pun intended)

Has anyone had any recent success with _imagesearch ? 

If so, please post a small snippet of code that you can confirm will return 1, so i can run it on my machine, and see if there is some wider systemic problem.

Here is my first test script for _imageSearch

#include <ImageSearch.au3>
#include <MsgBoxConstants.au3>

HotKeySet("{ESC}", "Terminate")
$ImgWindowsOrange = "c:\1.bmp"
$X = 0
$Y = 0

Main()
Func Main()
While 1
    $Found = _ImageSearch($ImgWindowsOrange, 0, $X, $Y, 0)
    If $Found = 1 Then
        MsgBox(0,"Found", $x & " " & $Y)
    else
        Sleep(250)
    EndIf
WEnd
EndFunc

Func Terminate()
    Exit 0
EndFunc

When I run the above I am getting a (44) error in the console:

Add this line to the top of your script - #AutoIt3Wrapper_UseX64=n

The DLL appears to be a 32 bit version.

NOTE: BTW, you probably could have troubleshot this yourself without asking the question if you'd taken 10 seconds to add some debugging to the UDF and/or your script. I found out that it won't run as a 64 bit process by finding out that the DLLCall,  in the previous line to your error, returned -1 meaning the DLL can't be used. Added the line above and that fixed the issue. Also, if you don't have the DLL in your script directory you're going to get the same error, the UDF uses a relative path for the dll filename.

The Dll file is in the script directory C:Program Files (x86)Autoit3Include. When I type _ImageSearch in Scite I am not getting the visual helper popup screen that tells me what I need to put in for the function to run which makes me think that the AU3 file is in the wrong place.

Is there a 64 bit version of this DLL file out there somewhere?

Regarding the troubleshooting, I don't know how to go about doing that even though I just read what you did. Also since this isn't in the installation of autoit by default I want a google searchable solution  so others can get the answer without asking.

Still doing the same thing. Do you mean put the #AutoIt3Wrapper_UseX64=n at the top of the ImageSearch.au3 file?

Is the DLL in the same folder as the imagesearch UDF file?

Have you tried troubleshooting this yourself to see where it's failing?

Add some consolewrites/msgboxes in the ImageSearch UDF file where it's failing to see why it gives you that error message instead of just reposting your script and telling us it still doesn't work. Scite4AutoIt3 comes with a handy debugging hotkey (CTRL+D) that will let you see what values a variable holds as the script is running. Click on the variable name, and hit CTRL+D and then save the file, and run your script.

I havent used imagesearch yet but tested a sample. Currently no 64bit pc on my place.

Question:

I wanted to know if i compiled my script and use it to other pc (which autoit never installed on it).. will the ImageSearchDll.dll required to be copied to those pc?

why is this script presing me the variable multiple times? how can i add a short sleep after the click if image was found so that the speed of the script is not reduced

Not sure I understand, but you could start by adding a short sleep after the click.

Hello,

I have problems to make this dll works with a python script. With autoit, all is ok and it works like a charm but i would like to use it with python :/

Here is my script :

import ctypes

dllFunc = ctypes.cdll.LoadLibrary('ImageSearchDLL.dll')
dllFunc.ImageSearch.argtypes = (ctypes.c_int, ctypes.c_int, ctypes.c_int, ctypes.c_int, ctypes.c_char_p,)
dllFunc.ImageSearch.restype = ctypes.c_char_p

_result = dllFunc.ImageSearch(0, 0, 1920, 1080, b"myPic.bmp")
result = _result.value
print(result)

The python debugger show me : "ValueError: Procedure called with not enough arguments (20 bytes missing) or wrong calling convention".

Any help will be appreciated. Thank you.

Download seems to be broken.

Guess you are referring to the original post made in 2008 by somebody that hasn't been around since 2011?
