BmpSearch - Search for Bitmap within Bitmap - Assembly Version

Recommended Posts

Beege

Heres a function for searching for a bitmap within another bitmap. The heart of it is written assembly (source included) and working pretty quick I feel. I have included an example which is pretty basic and should be easily enough for anyone to get the concept. 

You will be given a small blue window that will take a screencapture of that size:

set.PNG

 

It will then take a full screenshot and highlight all locations that it found

find.PNG

Please let me know if you have any issues or questions. Thanks!

Maybe you can add the ability to use mask and toloerance in your real cool lib? It'd make this a really invaluable.

nice.

See another one I wrote in AU3 

As I assume ASM will be much faster you could enhance it with some of the things I did in that AU3 version

  • differentiate the colordepth (B/W, 4,8,16,32, n colors)
  • find using line by line of the image searched (=search multiple bits at 1 call)

HomeScript

I have problem with this

#include <file.au3>
#include "BmpSearch.au3"

Global $Bmp1 = FileOpen(@ScriptDir & "\CALCULATOR.BMP")
Global $Bmp2 = FileOpen(@scriptDir & "\BACKSPACE.BMP")

Local $aCords = _BmpSearch($Bmp1, $Bmp2)

Error: 

Variable must be of type "Object".:
Local $iRowInc = ($tSizeSource.X - $tSizeFind.X) * 4
Local $iRowInc = ($tSizeSource^ ERROR

      I have a bunch of SDL_Surfaces loaded into memory.  I want to list them in a ComboBox.
      Using this code, I can load images to the combobox from file but not from existing SDL_Surface memory
      CODE ISN"T MEANT TO RUN
      ; Create combobox pic list example $aControl[$iControl_id][$eControl_data] = _GUICtrlComboBoxEx_Create($gui, $data_value, $data_x, $data_y, $data_w, $data_h, $CBS_DROPDOWNLIST) ; Image List for ComboboxEx Local $hImage = _GUIImageList_Create($gTile_w, $gTile_h, 6) ; Fill hImage with SDL_Surfaces stored in memory: aNPC_surf[scale][type][way][frame] For $i = 0 To 1 ; This works but only from file: ;_GUIImageList_AddBitmap($hImage, $gFolder_graphics & $gaWorld_info[$player.iWorld_cur][$eWi_filename] & "Tiles\" & $i & ".bmp") ; I've broken up a sprite sheet and want to insert into combobox from memory ;_GUIImageList_Add($hImage, $aNPC_surf[1][1][1][$i]) _GUIImageList_Add($hImage, _GDIPlus_BitmapCreateFromMemory($aNPC_surf[1][1][1][$i]), True) ;_GDIPlus_BitmapCreateFromMemory($aNPC_surf[1][1][1][$i]) ; Add the index number to combobox item _GUICtrlComboBoxEx_AddString($aControl[$eNPC_iPic_type][$eControl_data], $i, $i, $i) Next ; Set hImage list to combobox control _GUICtrlComboBoxEx_SetImageList($aControl[$eNPC_iPic_type][$eControl_data], $hImage) Anyone know if I can convert from SDL_Surface to hBitmap?  Maybe I'm doing something else wrong.
       
      I've seen hBitmap converted to SDL_Surface but I don't really understand it yet:

      I developing simple script for one program to do the automatic clicks.
      Now I developed on xp and win 7, but on win 10 gives me error.

      But the point for me to make it clear and not having basic mistake
      with choosing x64 and x86 system.
      So if I choose x64 system, does it going to work on x86?
      when compiling do I need to check or uncheck x64 compatibilities?
      Right now I'm installing new autoit v3 full install and it ask me what version to do like:
      - use native x64 tools by default
      - Use x86 tools by default (recommanded for compatibility)
      I assume I should use x86, because this is for 32bit machines?

      I know those are the basic questions of building the application for windows or any OS,
      but I didn't do any of this and if someone can give me information, just to do point,
      use always that or this, it would be great!

      I am busy with building a solution for change monitoring of VOIP call program and to be properly automated means among others need for some limited OCR functionality. Current works of others are way too much overkill for this case what makes the need to build it myself. But to do it properly I significantly have to increase my knowledge about digital graphics management.
      For now I already have discovered here and there some mind blowing  Autoit miracles what can be achieved with Windows own possibilities to manipulate that what is output to the monitor. And as far I can judge there are 2 options to process graphics without use of any external libraries like ImageMagick, FreeImage and so on. These are:
       WinAPI  GDIPlus It is for me quite obvious to have various holes in general understanding of graphics and it is once more very clear what advantages gives consistent general study in 1 or another official institutions like University.  Cause there you are introduced into certain domain of knowledge in a way which usually has been perfected over long period of time. So you are not overloaded by stuff which requires a certain amount of information to be initially clear for you. For example, before starting to solve physics you first learn to read, count and so on and then move to subjects like physics.
      Though in my case opportunity to study in such educational system I had only for 8 years, from my 7th to 15th year of age in the country that was falling apart now Ukraine but used to be USSR, was all what it was. After have immigrated to Netherlands possibilities to study further haven't occur. And this therefor causes often various implications when going deep in that or another field of practical knowledge acquiring for any needed physical result, like programming to perform enormous amount of tasks. In this particular case automating VOIP call program.
      Anyway, right now I think the best direction to move is to concentrate on as basic as possible image management and if someone would maybe explain in general what is a pixel will definitely help. Particularly I am very curious about how to do picture manipulations in Autoit. Especially would help a lot to produce eventually following functions:
      createImage($imageFileName, $width, $height, $color) readImagePixel($imageFileName, $x, $y)  writeImagePixel($imageFileName, $x, $y) I do not know exactly how image is handled in computer but preferably above mentioned functions should deal with so far possible origin of graphics creation on computer. But nevertheless I definitely would love to hear any proposition for solution.
      The problem with explaining screenshots:
       VOIPConnect full Window  Part of Window with control to monitor for changes  Exact location of area where actual changes occur and have to be processed  It comes down to a rectangle of approximately 51 pixel wide and 7 pixel high. In fact if I get to learn as far as to be able exactly read, write and compare 2 images consistently across different computers I could narrow down then even further the area to watch as little as a square of 2-5 pixels wide. 
      To finish here is last detail about particularly no need for ultra fast solution at all. This because it is needed only once when it is first run on a new computer and to have to wait few minutes while it is being set instead of just a few seconds make no sence.
      This is it and what I too think to do beside this very particular case is to purify out beautiful generic Autoit functions for core image manipulation by using WinAPI or/and GDIPlus.

      Hi all,
      I'm trying to find how to draw an image (create a label in mspaint) and save it as .bmp. And set it to be a wallpaper
      I also need to know what wallpaper is use now, for restore it when the script is closed.
      What is the best way to do it? Do I need Gdi+ for it?  I use this code (which I found here in forum) to set a .bmp file as wallpaper:
      Func _ChangeWallpaper($sFile,$iType) ; Changes the wallpaper to $sFilename using $iType as: ; 1 Tiled ; 2 Centered ; 3 Stretched ; any other value (usually 0) unchanged ; ; Returns ; 0 if everything is allright. ; -1 if $sFile does not exist. @error is set to 1 ; -2 if £sFile is not a .bmp file. @error is set to 2 If Not FileExists($sFile) Then SetError(1) Return -1 EndIf If StringTrimLeft($sFile,StringInStr($sFile,'.',0,-1)) <> 'bmp' Then SetError(2) Return -2 EndIf Select Case $iType = 1 RegWrite('HKCU\Control Panel\Desktop','TileWallpaper','reg_sz','1') RegWrite('HKCU\Control Panel\Desktop','WallpaperStyle','reg_sz','0') Case $iType = 2 RegWrite('HKCU\Control Panel\Desktop','TileWallpaper','reg_sz','0') RegWrite('HKCU\Control Panel\Desktop','WallpaperStyle','reg_sz','0') Case $iType = 3 RegWrite('HKCU\Control Panel\Desktop','TileWallpaper','reg_sz','0') RegWrite('HKCU\Control Panel\Desktop','WallpaperStyle','reg_sz','2') Case Else EndSelect RegWrite('HKCU\Control Panel\Desktop','Wallpaper','reg_sz',$sFile) DllCall("User32.dll","int","SystemParametersInfo","int",20,"int",0,"str",$sFile,"int",0) Return 0 EndFunc  
      The flow that I understand should be:
      1) Check what wallpaper is in use now. I can find the path to it by going to registry  key named "wallpaper" here :[HKEY_CURRENT_USER\Control Panel\Desktop]
      2) Create a file mspaint
      3) Create a label with its properties (size,color) in this file
      3) Save this file in some temporary directory
      4) Set a created file as a wallpaper using the above code
      5) When the script is closed restore the old wallpaper.
       
      So again, my question is how to create a .bmp file with label in it?

      Is there anyway to create an assembly for AutoIT so that I can use that in Powershell or Dotnet supported languages like c#.
      Like I want to use the functionality of _ArrayDisplay of AutoIT in C# by creating a assmbly/library and using that in the target language.
