Advanced Pixel Search Library

[FastFrench]

Maybe your dll file was corrupted then. It happens some rare times. You may want to check for viruses on you PC too.

Do someone have problems with the current version (2.2) ?

Hi thank you for your library but i have serious problem with it.

#include "FastFind.au3"
#Include <WinAPI.au3>
#include <Array.au3>
AutoItSetOption("WinTitleMatchMode", 4)
Global $Diff
Func MakeScreen1 ()
While 1
FFSnapShot(0,0,100,100,1)
;FFDuplicateSnapShot(1,3)
ConsoleWrite("FFSnapShot1" & @CRLF)
Sleep(1000)
FFSnapShot(0,0,100,100,2)
;FFDuplicateSnapShot(2,4)
ConsoleWrite("FFSnapShot2" & @CRLF)
Sleep(1000)
$Diff = FFIsDifferent(1,2)
ConsoleWrite("FFIsDifferent: " & $Diff & @CRLF)
WEnd
EndFunc
MakeScreen1()

There are allways errors after FFIsDifferent function execution, when i try to make new snapshot at same slot. And also it breaks While.

Hello,

do you know if Visual Debugging is active ? That may explain why you always have differences : when Visual Debugging is set, then first change is shown on the screen (with a small red circle)... appearing on the next capture.

Can you do the same test with all debugging off ?

Thanks,

I have got a problem when I try more specify 

$Left and $Top

FFNearestPixel(10, 10, 0x00AB0C45, true, 10, 10, @DesktopWidth, @DesktopHeight)

it  always return @error 

FFNearestPixel(10, 10, 0x00AB0C45, true, 0, 0, @DesktopWidth, @DesktopHeight) 

this one is ok

[Geir1983]

Thanks, v2_2 solved the startup problems ive been having

Any chance you will be adding the image search functionality? Beeing able to search the same screenshot for several images would speed up my project alot.

Wishlist:

Load snapshot from bmp/jpg

Find (smaler) snapshot inside another snapshot (option to return "found(true/false)" or array of results with coords)

Hello, i want ask: I can make better my script for speed Return? With FastFind. If yes, how to translate? This Work for Video player (video area) in Window mode.

Thank you very much, if can help me. Sorry for my Bad English)

DO NOT REPLACE THE SCRIPT A SECOND TIME - READ MY POST BELOW, WE DO NOT SUPPORT GAME AUTOMATION HERE

Code removed a second time - it had better be the last

Tixan,

Welcome to the AutoIt forum.

 

This Work for Game

I suggest you read the Forum rules (there is also a link at bottom right of each page) - partcularly the bit that says no game interaction - before you post again.

Hello,

honnestly, I've switched to C# like 18 months ago, and C++ looks very bulky now for me to use.

So if there is massive demand for for simple-to-implement feature, OK, but otherwise, few chance.

 

Sorry

@FastFrench:

Several posts ago you mentioned to move the source to svn or smth like that so others can help to improve it.

You still plan this or not?

Hey FastFrench

 

I have question : on your FastFind_Demo.au3, the FFLocalizeChanges crashes on the second loop. Do you have any idea what could be the problem?

Even i tried this code and when i press "end" button a second time, it crashes.

expandcollapse popup

#include "FastFind.au3"
#Include <WinAPI.au3>
#include <Misc.au3>


HotKeySet("{ESC}", "TheEnd")
HotKeySet("{HOME}", "home")
HotKeySet("{END}", "end")

$i = 1
$dir = "D:\FastFind 2_2\"

FFSnapShot(225, 293, 1140, 705, 1)
FFSaveJPG($dir & "image1",100,true,225, 293, 1140, 705)  

while 1
   Sleep(10)
Wend

func end()

  $i = $i + 1

  FFSnapShot(225, 293, 1140, 705, $i) 
  FFSaveJPG($dir & "image" & $i,100,true,225, 293, 1140, 705) 
  $Res = FFLocalizeChanges(1,$i,0) ; Search all differences between two SnapShots
  if @Error Then
    Beep(500, 300)
  Else 
    MsgBox(0, "Mouse x,y:","Change detected : ("&$Res[0]&","&$Res[1]&","&$Res[2]&","&$Res[3]&"), "&$Res[4]&" pixels are different")
  EndIf
Endfunc
   
Func TheEnd()
  CloseFFDll() ; Unload the DLL, free the memory, close files...
  Exit
Endfunc

Hello,

you're right, I've reproduced the same problem on the Demo. Not sure if that's the only reason, but looks like there're tons of useless data written in the trace file for each call to IsExluded (that is, for each pixel in the area !). I don't have the sources at hand right now, I'll check this problem ASAP.

You can maybe avoid this by removing all Debug data : set all FFSetDebugMode into FFSetDebugMode(0).

@neuronet : sorry, not yet. There is so much I'd like to do on this library; that each time I open the project, I spend all my time available to debug and improve it, and so do not proceed the needed cleaning.

[neuronet]

Thanks FastFind. I'm waiting for your cleanup.

What would be maybe an interesting "expansion" of your actual dll is to implement some of the functions in a d3d9.dll since directx windows often produce problems. Within a d3d9.dll it would be possible then to work directely with the captured backbuffer.

Hi, I always get error from FFSnapShot when I try to input the screen size.

Hi, I always get error from FFSnapShot when I try to input the screen size.

I think the error is in line 3 of your script.

Hi, FastFrench

First of all, thank you for a great library. I have one issue though, one that is already mentioned;

Any update on this?

I'm having the same issue (crash) as BeginnerUser when running FFLocalizeChanges(0, 1) the second time (in FastFind_Demo). I've tried setting FFSetDebugMode(0), but it didn't help.

I need to compare two snapshots and see if there's been any changes. Is there a workaround?

Either way, I'd love to help out if you decide to share the source. Happy holidays! :-)

Just a small update to my last post with some new bits of information that might help debug the issue:

• I downloaded version 1.3 of the script (from http://www.autoitscript.fr/forum/viewtopic.php?f=21&t=7090) and it works with FFLocalizeChanges and FFisDifferent (tried on autoit x32 on Windows 8.1)
• When trying version 1.5-2.1 I get the error message that FastFind.dll cannot be opened when initializing the script.
• Version 2.2 crashes on second run of FFLocalizeChanges (as described in previous post)

Hope this helps.

Hello!

I'm trying to use this library to create 60x60px window to show 6x zoomed 10x10px area under the mouse pointer to make precised snapshots. After FFSnapshot I'm using FFGetPixel, but it returns color 0x00737373 or 0xffffffff, though when i'm using FFSaveBMP i'm getting what expected - colorful picture. Here is code fragment:

$pos = MouseGetPos()
   
   FFSnapShot($pos[0]-5, $pos[1]-5, $pos[0]+4, $pos[1]+4, 0)
   If Not $emcTempFileTaken Then
      $emcTempFileTaken = True
      FFSaveBMP ( "temp" )
   EndIf
   
   Local $c
   
   For $x = 0 To 9
      For $y = 0 To 9
         $c = FFGetPixel($x,$y, 0)
         DbgLog($locn&'.(x,y)=('&$x&','&$y&') c='&Hex($c))
      Next
   Next

What is wrong with FFGetPixel?

.................................................
Well, I found the reason: FFGetPixel needs coordinates relative to source of the corresponding snapshot, but not snapshot itself, i.e. if you take FFSnapShot(10, 10, 50, 50) then you should use FFGetPixel(10,10) to get color of snapshot's left-top corner pixel, but not FFGetPixel(0,0)!

I spend valuable time to understand this by experinence, so I think this particular case and related ones must be explained in documentation.

It seems that whenever I call the FFIsDifferent function, my script crashes, similar to the posts above.

Hello !

First I'd like to apologize for providing such a scarse support for this library.

We have a proverb in French that says : "Tout vient à temps à qui sait attendre". I'm not sure how it translates into English. But well, here it is : I finally found back the last version of FastFind sources, and put that on a shared repository (GitHub). That's very optimized but honestly not very readable code. Hope some of you will be able to improve it.

Here is the link : https://github.com/Fastfrench/FastFind
 

Please let me know when you use or change those sources, or if you have trouble using GitHub.

You can also input issues on GitHub to track them properly. And keep this post to communicate about the changes.

If you want to contribute actively on this project, please show me some suggested changes you'd like to include.

If it shows that you know what you're doing, then I'll set you as a contributor on the GitHub project (so you can directly change the sources on GitHub).

Thanks to all,

FF
