ImageSearch multiple occurrence

Recommended Posts

I have developed a script to find multiple or all occurrence of an image from desktop using the ImageSearch UDF. Please note that the resulting array has the starting position of the images, not middle.

#include-once
#include <Array.Au3>
#RequireAdmin
#AutoIt3Wrapper_UseX64=Y

Global $y = 0, $x = 0 ;Result x and y coordinates
Dim $aResult[1] ;Resulting array
Global $sImagePath = @ScriptDir &"\Rect.bmp"
Global $nImageWidth = 0 ;Image width
Global $nImageHeight = 0 ;Image Height
_ImageSearchMultiple()

Func _ImageSearchMultiple()
    Local $search = _ImageSearch($sImagePath, 0, $x, $y, 10)
    If $search = 1 Then
            _ArrayDisplay($aResult)
    Else
        Msgbox(0,"Not Found","Image Not Found")
    EndIf
EndFunc

      The code is solid and simple, it can almost explain itself.
      This is the native autoit way to do the "imagesearch", no 3rd party .dll needed.
       
      It gets "your.bmp", and "screenshot.bmp" ----> Convert the  .bmp files into 2D-Arrays (Malkey's function)  ----> Compare the 2D-arrays, return the matched position.
       
      Tested on: Windows 7; Windows server 2008R2; Windows 10 1809.
       
      Pros:
      It is native. No extra .dll needed
      It is super robust. (I used to have lots of funny results using other imagesearch libs).
      It gets screenshot the same you get your screenshot crop, so it always gets a solid result, and 100% accurate.
      The code is very simple and friendly, all level users can understand and use it.
       
      Cons:
      It is slow to convert your.big.screen.bmp into a 2D-array, and may consume 200+MB of memory and may take 5 - 20 seconds to return the result. (the actual search in an array is fast, but the conversion from .bmp to array is slow. The speed depends on your CPU speed and your screen size).
      Correct: now optimized,  it's ~5 seconds and ~ 70MB ram usage.
      It is a pixel-by-pixel color-code strict comparison in the "array-in-array" search, so you have to use the 24-bit BMP file, no "Tolerance" allowed.
       
      2019-Jun-11: script update:
      Same day updated: Update example;  Optimize the algorithm for performance, now most computers can get the result in ~5 seconds, using ~70MB temporary memory, for the 1920x1080 resolution screen.
       
      2019-Jun-12 script update:
      It now uses "PrintScreen" hotkey to save the screenshot.bmp (restores the user's old clipboard content after it is done) ~This is the only way to make sure the screenshot matches exactly what the user is seeing, after doing dozens of harsh tests.
      The reason: The UDF "ScreenCapture" and "ImageSearch.dll"  are not reliable for an unknown reason. Some window/dialogue special drawings are "invisible" in their screenshots.
      But the "PrintScreen" key -> Clipboard -> screenshot.bmp, this method always catches exact things showing on the screen.

      Hello, I need to find an image on screen and return it's position left, top, right, botton.
      I'm using the ImageSearch function but it only returns 1 or 0.
      Any ideas? Thanks!
    • By Errious
      Hello,
      maybe i am just tired or i did not understand exactly how to use ImageSearch for different pictures, but i tried now a few things with my example script and only the first part is working.
      Explaining what i try to do, at work we have a programm running which has three different states, they are visible but sometimes the statuses of the process is not running and to avoid a long time without progress of the programm i searched to get a way to have a better visible notification as existing, so there is grey as work in progress, orange for not running and red for aborted, now when the states are changing i would like to receive a little window that is just telling the actual status.
      #include <ImageSearch2015.au3> #include <MsgBoxConstants.au3> #include <AutoItConstants.au3> $x1=0 $y1=0 While 1 sleep(100) $image1 = _ImageSearch("red.png", 1,$x1,$y1,0) If $image1 = 1 then SplashTextOn ( "", "RED !" , 100 , 50 , 1800 , 220 , $DLG_TEXTLEFT, "Arial" , 12 , 500 ) Sleep(1000) SplashOff() sleep(100) EndIf $image2 = _ImageSearch("orange.png", 1,$x1,$y1,0) If $image2 = 1 Then SplashTextOn ( "", "Orange !" , 100 , 50 , 1800 , 220 , $DLG_TEXTLEFT, "Arial" , 12 , 500 ) Sleep(1000) SplashOff() sleep(100) EndIf $image3 = _ImageSearch("grey.png", 1,$x1,$y1,0) If $image3 = 1 Then SplashTextOn ( "", "Grey !" , 100 , 50 , 1800 , 220 , $DLG_TEXTLEFT, "Arial" , 12 , 500 ) Sleep(1000) SplashOff() EndIf WEnd As i said before, part one to receive the state for aborted is working, so i get the splash window for this, but what do i miss for the other two?
      I put the While statement in for continuously running as long it is needed when the program is in use, but i believe i missed something.

      I have loaded FastFind into my code and it takes a snapshot and creates a BMP file from it. 
      My issue is now I want to imagesearch from that BMP file (or snapshot memory) and look for a specific image from that image and get the coordinates from that. 
      I have looked at all the documentation but I cannot find anything to assist me.
       
      Does anyone have any idea?
