ImageSearch Usage Explanation

[Fir3man]

Hi,

I can't fix problem with autoit library. Its stop working in new versions of autoit.

I downloaded library from this page. When I try to compile script I get error

I fix it with changing declaration of functions like this:

Func _ImageSearch(ByRef $x, ByRef $y,$findImage,$resultPosition,$tolerance, $HBMP=0)

After that I get 2 different errors:

1) when I'm using 32bit version of DLL:

!>12:54:03 AutoIt3.exe ended.rc:-1073741819

2) when I'm using 64bit vertion of DLL:

$result = DllCall("ImageSearchDLL.dll","str","ImageSearch","int",$x1,"int",$y1,"int",$right,"int",$bottom,"str",$findImage,"ptr",$HBMP)

$result is always = 0;

And its not an array, just variable = 0.

I'm using 64bit Windows 8.1 (had similar problems at win 7 x64). I compile my scrips at 32 bit always.

Sorry for My English, I hope more experience programmers will help me.

Thank you.

Are you sure you can simply change the parameters of the Func?

Show your total code which gave the initial error so we can have a look.

Did you have similar errors like me? I mean with that ByRef part.

 

I use example code to call func

#include "ImageSearch.au3"

HotKeySet("p", "checkForImage")

global $y = 0, $x = 0

Func checkForImage()
Local $search = _ImageSearch($x, $y,"checkImage.png", 0, 100)
If $search = 1 Then
MouseMove($x, $y, 10)
EndIf
EndFunc

while 1
sleep(200)
WEnd

I tried the code posted by tbodine88 () to help in debug, but it always return 1 - where it cant use the DLL.  Im using 64 bit.  I tried 32 bit but it is not working. can someone help pls? how can i have this work for me? thanks 

[xadi]

Unfortunately, ImageSearch does not work for me neither.

#include <ImageSearch.au3>

global $y = 0, $x = 0

Func checkForImage()
   Local $search = _ImageSearch('./00-login.bmp', 0, $x, $y, 0)
   If $search = 1 Then
      MouseMove($x, $y, 10)
   EndIf
EndFunc

HotKeySet("p", "checkForImage")

while 1
   sleep(200)
WEnd

After I run it - DLL library crashes. Did anyone manage to fix the problem?

[rm65453]

Don't want to hijack the threat but since I am having very similar problems thought I should just add it to this thread instead of creating a new one.

The script runs fine with the x64 dll and au3 file but the trouble is the result is always 0.

I have only tidied the imagesearch file and then complied the following code using autoit_x64 compiler.

 
#include <ImageSearch.au3>
#include <GDIPlus.au3>
$fileA = "full path to the file\meeting.bmp"
 
_GDIPlus_Startup()
 
$hImageA = _GDIPlus_ImageLoadFromFile($fileA) ;this is the firefox icon use something else if you don't have it.
$hBitmapA = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImageA)
 
$x = 0
$y = 0
 
$result = _ImageSearch($hBitmapA, 1, $x, $y, 20) ;Zero will search against your active screen
If $result > 0 Then
MouseMove($x, $y)
MsgBox (0, "Result", $Result)
EndIf
MsgBox (0, "Result", $Result)
_GDIPlus_ImageDispose($hImageA)
_GDIPlus_Shutdown()
 

any help would be much appreciated. it only worked once after I downloaded the demo file but since then it has stopped working completely.

edit: I added the debug lines to the imagesearch.au3 file as well and didnt get any errors (which I believe is good) but the result is always, as previously stated, 0.

Sorry about multiple posts but I am not able to edit my previous post.

So somehow using the standalone Aut2Exe v3 and compiling it under x86 works (using the 32 bit files). Still no luck with the 64 bit though which is fine except for the fact that the exe file crashes after most runs. 

here are the error details

here are the links to the error files. hopefully someone can point me the source of the error. going to start doing some trouble shooting now.

[rm65453]

ok so I got this to work, somewhat successfully. Turns out it doesn't like mixing png and bmp formats. 

now the problem I am having is to make it search extended displays. currently it only searches the display with the toolbar underneath.

any ideas?

Am very close to getting it to work well enough to serve my purpose.

[Technokrat]

why this it >.< can anyone help me

[Maxlvs]

After having lot of issues myself with getting ImageSearch to work I decided to make topic with explanation how to proper use this script.

Here is link of original topic at this topic: '?do=embed' frameborder='0' data-embedContent>>

Credits to kangkeng for creating such useful piece of code.

 

Description of parameters from ImageSearch.au3 itself:

; Description:   Find the position of an image on the desktop
; Syntax:        _ImageSearchArea, _ImageSearch
; Parameter(s):
;                $findImage - the image to locate on the desktop

EndIf
EndFunc

while 1
sleep(200)
WEnd

I would like to apologize if by writing this I offended any of member that thinks this script is too simple to even have it explained, it's just as me being new to autoIt it took me so much time getting around errors and making this script to work.

Thanks for reading, if you bump on any problems using it post it here, I will try to help you fixing it and update topic for further reference.

Download links:

32bit: ImageSearch 32bit.rar

64bit: ImageSearch 64 bit.rar

 

 

i have a question iam trying to get the image search to work and it says error line 1 #include <ImageSearch.au3> i think because i dont have that downloaded to my library but i tried to download theses and it didnt really do anything how could i get this ? 

[JohnOne]

The links are in the post you quoted.

Did you extract it?

Did you put it in your script folder?

Did you change  #include <ImageSearch.au3> to  #include "ImageSearch.au3"?

[Maxlvs]

Unfortunately, ImageSearch does not work for me neither.

#include <ImageSearch.au3>

global $y = 0, $x = 0

Func checkForImage(main.bmp)
   Local $search = _ImageSearch('main.bmp', 0, $x, $y, 0)
   If $search = 1 Then
      MouseMove($x, $y, 10)
   EndIf
EndFunc

HotKeySet("p", "checkForImage")

while 1
   sleep(200)
WEnd

After I run it - DLL library crashes. Did anyone manage to fix the problem?

where do i put the image and i put the imagesearch file in the include folder or do i put it the script folder because the script complies but when i click go to run it it wont move the mouse or hit the p hot key still to run but it gives me 

>"E:DownloadAutoIt3SciTE..autoit3.exe" /ErrorStdOut "E:DownloadFindIMG.au3"    

"E:DownloadFindIMG.au3" (5) : ==> Expected a variable in user function call.:

[Maxlvs]

iam not 100% sure what place your suspost to save the image 

[nullschritt]

It would be nice to have the functionality to search for images in another image, I'm thinking this could lead to some basic facial recognition, if anyone wanted to take ti there, among other uses.

[ViciousXUSMC]

I wanted to start looking at this, no luck so far.

Just the most basic example I can think of.

Took a screenshot of an icon on my deskto and named it VMWare.bmp and put it in the script dir.

Used the same code as the first page example with a bit of added tollerance and I get an error.

**

Line 44 

if $result[0]="0" then return 0

Error: Subscrit used on non-accessible varible.

**

Code:

#include <ImageSearch.au3>

HotKeySet("p", "checkForImage")

global $y=0, $x=0

Func checkForImage()
Local $search = _ImageSearch("VMWare.bmp", 1, $x, $y, 10)
If $search = 1 Then
    MouseMove($x, $y, 10)
EndIf
EndFunc


While 1
    Sleep(200)
WEnd

I have tried the 32bit and 64bit dll + udf and put them in the autoit Include folder and the scripts directory both will recreate the issue unless I use the 32bit dll in the script folder it crashes autoit outright.

[BrewManNH]

This UDF has no error checking in it, you'd need to add some so that you won't get those errors. For example test $result to see if it is an array before acting on it.

[ViciousXUSMC]

Yeah I was doing some error checking.

I got the script working without error, just not functioning properly/well.

I had to use the x64 udf and dll and then right click and explicitly tell the script to run as x64 then no errors occured but the image was not being found.

I bumped up the tolerance higher and higher until around 150 it found something but not the image it should have found.

I'll experiment with different image captures and see if I can get it working better.  I use a 3 monitor setup and I am searching for an icon on the main monitor, when it finally found something it was nothing close to the image I took a picture of :/

Edit: Larger image works with a 175 tolerance.  Took a capture of the entire icon.  About a 3 second lag from when I fire the function till when it finds it. 

Edit2: Working Great now used irfanview to do the screen capture, crop, save instead of the other stuff before that was probably degrading the image quality and resampling it.

Where can I download the most recent dlls for image search?

[ShadowEagle]

why this it >.< can anyone help me

Im having the same issue, any resolution to it??

 

local $x1

Local $y1

local $search = _ImageSearch($ImgDir&"image.PNG",1,$x1,$y1,0)

 

 

if $search=1 Then

    MouseMove($x1,$y1,3)

    MsgBox(0,"Found","Found a recycle bin with stuff here...")

EndIf

 

running it gives me the error above....
