ImageSearch Usage Explanation

[careca]

There's no loop, so it just ends.

Hello guys....Im trying to use Image search to search an image in web.....I tried using the above Image search dll. But this dll only works for images on my desktop and not in IE browser. Please help me to search an image in IE..

Change line 2154 and you should be fine.

If you have downloaded the full Scite4AutoIt3 package you can just run the Tidy command and it will probably fix the formatting.

Regarding issues encountered when compiling the ImageSearch.au3 file, in addition to the issue pointed out by @Rossi46 above, I've also encountered additional issues when compiling that code with the current AutoIt release. They involve run-time errors due to undeclared variables, since my calling code requires that all variables be declared (this is not reported at compile time).

The variables in question are: (1) $right -- For some unknown reason, specifying that variable in the DllCall function is reported as undeclared, even though itt's properly declared in the outer function. There may be other work-arounds, but what worked for me was to specify a different input argument name, then declare $right and assign it the argument variable.

The other is more straightforward; the array variable $array was never declared within _ImageSearchArea(). Doing so solved my problem.

Here is a version with all the corrections I required:

Hi, is there a way to search for multiple images on the same fuction execution? Example down there is searching for 10 different pictures on the same window each loop, one imagesearch for each image to compare. Is there a way to do 1 imagesearch with all 10 to compare running 1x the imagesearch function? I need to know cause running the script like this i keep getting hundreds os microfreeze, more like a shutter effect while alt+tabbing and thats driving me crazy.

If its not possible, i'm planning in migrate to C# or Python to make my scripts with image search and stuff, do you guys recommend any of those?

If _ImageSearchArea($picture1, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture2, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture3, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture4, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture5, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture6, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture7, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture8, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture9, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 or _ImageSearchArea($picture10, 1, $searchwindow2Pos[0], $searchwindow2Pos[1], $searchwindow2Pos[0]+$searchwindow2Pos[2], $searchwindow2Pos[1]+$searchwindow2Pos[3], $picture2x, $picture2y, 96, 0) = 1 Then

Do you add the .DLL files to the autoit script editors library to be able to call it in the script editor? because it's not popping up for me.

[dwaynek]

how do i get ImageSearch to work in a multiple monitor setup? it seems to work on my main monitor but can't find the image on my secondary monitor. here's my code:

 

#include <ImageSearch.au3>

HotKeySet("p", "checkForImage")

global $x = 0, $y = 0

Func checkForImage()
msgbox(0,"","running!")
Local $search = _ImageSearch('image.png', 1, $x, $y, 0)
If $search = 1 Then
MouseMove($x, $y, 0)
EndIf
EndFunc

while 1
sleep(200)
WEnd

nvm i used _ImageSearchArea() instead with negative starting values and that worked.

[gurrenm3]

Hey, if anyone needs help with this, here's a tutorial video on how to do this:

 

[HansHenrik]

running this simple code:

 

#include <ImageSearch.au3>

   Local $findImage="10parsed.png";
   Local $center=1;
   Local $foundX=0,$foundY=0;
   Local $tolerance=10;
   _ImageSearch($findImage,$center,$foundX, $foundY,$tolerance);

it enters

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

then crash on the 

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

line with the error
"C:\Program Files (x86)\AutoIt3\Include\ImageSearch.au3" (45) : ==> Subscript used on non-accessible variable.:

and when i run

ConsoleWrite(VarGetType($result));

it prints Int32 , and it contains 0.. 

guess that means the error-check code is somewhat broken (it should check if(result==0)  rather than if(result[0]==0)) and that there was an error?

[spuuunit]

I get error if I include ImageSearch.au3 in another folder than where my script is. Hard to explain folder structure so I uploaded a small example.

I think the path to ImageSearchDLL.dll is what gives error, but I tried changing it to a full path without any luck.

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

You are pretty persistent in not providing normal required information ... aren't you?  

What Error?
Post code here in a codebox in stead of externally!

Oh ok. This is my code:

#include <Includes\ImageSearch\ImageSearch.au3>
While 1
    Local $search = _ImageSearch('find_this.bmp', 0, 0, 0, 0)
    If $search = 1 Then
        MsgBox(0, "", "image found")
    EndIf
    Sleep(500)
WEnd

[Jos]

I can only assume that the DLL isn't found as the DLLCALL doesn't return an Array, so where is the DLL located ?

Jos

EDIT: Did you even look in this thread whether others had this issue?
I see on page 2 of this thread several similar questions and a possible answers.

Oh sorry, I found that now.

[voidFF]

Hi

I have made some research to speed up the search.

Max Speed is screen frequency 60 search per second or more like 144Hz.

to reach the max speed you can:

-Preload the dll ex.: $dll = DllOpen("ImageSearch.dll")

-Use directly dllcall ex: $res = DllCall($dll, "str", "ImageSearch", "int", $left, "int", $top, "int", $right, "int", $bottom, "str", "*TransFFFFFF *85 picture.gif")

-Reduce the search area

-Reduce Image size

-Use gif

-Use Black and White if possible

-use RAM Disk to Speedup the load of the image and preserve your hard drive

-Make temp folder on your ram disk with ex:

EnvSet("TEMP", "D:\")
EnvSet("TMP", "D:\")

Hi all. Long time user, first time poster.

 

I'm having scaling problems with the image finder. So from what I can tell, the image finder works but not what I want it specifically for.

I'm trying to find this image - https://ibb.co/zxPXwLJ

When I search my screens, it doesn't find the image as it is quite small (approximately 70x70 pixels on a 1080x1920 screen. But if I open the Windows folder with the preview of the image it finds it. In Windows folder it will find the image when the view is set to "Large Icons" but can't find it on "Medium Icons".

Is there a way to make the image finder work on a smaller scale like that pixel size or adjust the code to find a match based on pixel size?

Here is my Code:

#include <ImageSearch2015.au3>

$x1=0
$y1=0
$i=0

$picture = "arch.PNG"
While $i<2
   $result = _ImageSearch($picture,0,$x1,$y1,0,0)
;_ImageSearch($findImage, $resultPosition, ByRef $x, ByRef $y, $tolerance, $transparency =0)
   If $result=1 Then
      ConsoleWrite("Yes")
      Sleep(900)
      $i=$i+1
   Else
      Sleep(900)
      $i=$i+1
   EndIf
WEnd

I have been using imagesearch to great success but I have one issue, I get this popup when I use it and I don't know how to suppress it, any thoughts?
