ImageSearch Usage Explanation

[swatsapkraz]

When I have this part of the code:

local $search = _ImageSearchArea('check5.bmp', 1, 800, 40, 900, 80, $x, $y, 0)

Does the first parameter dictate the tolerance? In the code above that would be "1" or how do I dictate the tolerance as I have an image which is semi transparent which I would like to find no matter what screen is in the background.

I was trying to write a script that could check several areas searching for a specific BMP at the same time but I don't know how to use more than one imagesearcharea. Sorry for this, I'm a noob. Any help would be appreciated. Thanks

[careca]

Hmm not sure you can, it follows a pattern of search. Experts chime in pls.

[smahmud]

I have written a simple code and it's working great. Thanks for the great library. Here are a snippet -

WinActivate('My Window')

$x = 0
$y = 0
If _ImageSearch('searchButton.PNG', 1, $x, $y, 20) = 1 Then
   Return 1
ElseIf _ImageSearch('bundle.PNG', 1, $x, $y, 20) = 1 Then
   Send('{ESC}{LCTRL}{LCTRL}{LCTRL}')
   sleep(1000)
Else
   Send('{LCTRL}')
EndIf

Now my question is how can I use that _ImageSerach function in a specific program (background process) so that I can use my pc to do other work?

I know how to use control commands to click on background but I can't use _ImageSerach in background.

Please help.

Because, i believe, it doesn't work in the background, you have to be able to see the image yourself, in order for the code to work.

It takes a screenshot and finds the image you requested!
So it does not work with hidden windows or background processes!

[smahmud]

Thanks for the reply

I guess only way to do is screen capture on specific window and run search on that picture but I am not sure if there any function exists to do that.

One more question: How can i look for multiple occurrence of same image and return all the cords?

Thanks.

Then there's still a bug in the code, you cannot use black as its color value is zero, and only non-zero is accepted as transparent:

If $transparency <> 0 Then $findImage = "*" & $transparency & " " & $findImage

 

I had to change the ImageFile parameter when calling the DLL function to get transparency to work. It was missing the correct prefix for the transparency option.

For reference, the Image file options are here: https://autohotkey.com/docs/commands/ImageSearch.htm

*TransN: This option makes it easier to find a match by specifying one color within the image that will match any color on the screen. 

This is my updated _ImageSearchArea function with the transparency option fixed. Notice the inclusion of the *Trans text in the ImageFile parameter parameters.

If $transparency <> 0 Then $ImageFileOptions = "*Trans" & Hex($transparency) & " " & $ImageFileOptions

Func _ImageSearchArea($findImage, $resultPosition, $x1, $y1, $right, $bottom, ByRef $x, ByRef $y, $tolerance = 0, $transparency = 0);Credits to Sven for the Transparency addition
    If Not FileExists($findImage) Then Return "Image File not found"
    If $tolerance < 0 Or $tolerance > 255 Then $tolerance = 0
    If $h_ImageSearchDLL = -1 Then _ImageSearchStartup()

   Local $ImageFileOptions = ""
   If $tolerance > 0 Then $findImage = "*" & $tolerance & " " & $ImageFileOptions
   If $transparency <> 0 Then $ImageFileOptions = "*Trans" & Hex($transparency) & " " & $ImageFileOptions
   $ImageFileOptions = $ImageFileOptions & $findImage

   $result = DllCall($h_ImageSearchDLL, "str", "ImageSearch", "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $ImageFileOptions)
   If @error Then Return "DllCall Error=" & @error
   If $result = "0" Or Not IsArray($result) Or $result[0] = "0" Then Return False

    $array = StringSplit($result[0], "|")
    If (UBound($array) >= 4) Then
        $x = Int(Number($array[2])); Get the x,y location of the match
        $y = Int(Number($array[3]))
        If $resultPosition = 1 Then
            $x = $x + Int(Number($array[4]) / 2); Account for the size of the image to compute the centre of search
            $y = $y + Int(Number($array[5]) / 2)
        EndIf
        Return True
    EndIf

Hi guys!

 

So I´ve been playing around with AutoIt again after a couple of years of absence. I'm trying to make ImageSearch work in my favor and got a test script going that looks like this: 

#include <ImageSearch2015.au3>



Local $findImage[8], $resultPosition, $tolerance, $transparency, $waitSecs, $x, $y

$findImage[0] = 7
$findImage[1] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\HK.png"
$findImage[2] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\K4.png"
$findImage[3] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\K5.png"
$findImage[4] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\R8.png"
$findImage[5] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\S7.png"
$findImage[6] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\S8.png"
$findImage[7] = "C:\Users\Micke\Desktop\AutoIt Script\ImageSearch2015\SJ.png"

$x=0
$y=0
$waitSecs = 1

  $findImage =  _WaitForImagesSearch($findImage, $waitSecs, $resultPosition, $x, $y, $tolerance, $transparency = 0)
ConsoleWrite($findImage & @CRLF)

It works but kind of slow(2.5 s) and the area I want to search for those .png's is much smaller than my desktop, so my question is how would I go about setting that smaller area up in my script?

Is it possible to image search from resource file using this UDF ?

 

[JLogan3o13]

Yes

Spoiler

Sorry, not enough info? Perhaps if you gave more detail about what you're trying to do you'd get more in return

Wow great and easy. If someone  will search it

 

#AutoIt3Wrapper_Res_File_Add=img\search.bmp, rt_bitmap, TEST_BMP_1
Global $x, $y
Global $pic1
; set BMP image to picture control from resource  bitmap
_ResourceSetImageToCtrl($pic1, "TEST_BMP_1", $RT_BITMAP)

Case $imageSearch
            Local $find = _ImageSearch($pic1,0,$x,$y,0)
            If $find Then
                MouseMove($x,$y,10)
            Else
                MsgBox(0,"","Not Found")
            EndIf

Guys i have a problem i have at the same folder the ImageSearch.au3 file and the dll and also my new script and when i make the imagesearch at my main script its not working i have made the include at the start of my sciprt whats wrong?

you didn't post the script so we either do a wild guess or you share enough information to a a proper look.

[BrewManNH]

That's not a script, it's a picture of a script. Kind of like taking a picture of an apple doesn't feed you, giving us code in a picture doesn't help us help you.

The only thing I can guess is that you're trying to use the 64 bit image search, and running it as an x86 process. Due to the naming you're giving things and the fact that the x86 version of AutoIt is being executed.

[tonycst]

UDF has

#include-once at the top

If i include entire UDF (well, the main function of it) in my main script, what difference does it make ?.

I would end up with this.

Is there something i need to worry about when running this code like that in a loop ?
My main script will continuously look for that image until all its instances are gone.

I am trying to click off inventory items automatically.

Hello Centrally,

I tried using your code above with ImageSearch.au3 in Windows 10 x64 and it just hangs; see my code below, are you able to assist?, thank you.

#include <ImageSearch.au3>

HotKeySet("p", "checkForImage")

global $y = 0, $x = 0

Func checkForImage()
local $search = _ImageSearchArea('d:\autoit\Test.bmp', 1, 800, 40, 900, 80, $x, $y, 0)
If $search = 1 Then
MouseMove($x, $y, 20)
EndIf
EndFunc

while 1
sleep(200)
WEnd

[careca]

 The function has one more parameter, bitmap in the end, can be set to 0 try adding it like this.

_ImageSearchArea('d:\autoit\Test.bmp', 1, 800, 40, 900, 80, $x, $y, 0, 0) 

;Func _ImageSearchArea($findImage,$resultPosition,$x1,$y1,$right,$bottom, ByRef $x, ByRef $y, $tolerance,$HBMP=0)

Searching within a rectangle with 100x40.

[Kolokol1]

#include "ImageSearch.au3"

HotKeySet("p", "checkForImage")

global $y = 0, $x = 0

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

Win 10 64 bit

Why is this code not working?

checkImage.bmp
