Mallikarjun,

Wrong part of the forum, no attachments to be seen, and asking for someone to write code for you. Pretty poor post!

Thanks for reply, actuly i am using the code

$image1 = FileRead("C:\image\scree2.bmp")

$image2 = FileRead("C:\image\scree3.bmp")

If $image1==$image2 Then

MsgBox(0,"test","files match ")

Else

MsgBox(0,"test","files do not match")

EndIf

but i want to ignore the some portion in the image while comparing...

is it possible?

Why do you need to compare the image from the emulator? I take it you are running windows in a virtual machine? Why just not run the code there to check what you need?

[monoscout999]

Comparing the image file like a text is not correct, if the pic have a comment on the headder or something this will be different. if you want to compare the pixels of each you should use LockBits or something similar.

If you want to just read certain parts of a file then take a look at

FileSetPos()

function example.

EDIT:

linkage not working.

thanks for replying ... but i am looking for fing the perticular area in the image like buttons and buttons tex is displating or not ....

is fixel find with color is helpull for me?

C:\image\tt.bmp

[Mallikarjun]

Now i using $image1 = FileRead("C:\image\scree2.bmp")

$image2 = FileRead("C:\image\scree3.bmp")

If $image1==$image2 method to compare the images ... is it posible to compare the dowm portion and top portion of the image .....

2)And i have one more quetion i have used ....Func FileListToArray($Dir , $Dir2)

Dim $FilePath,$FilesList,$Files,$i

Dim $FilePath2,$FilesList2,$Files2,$j

$FilesList=_FileListToArray($Dir)

$FilesList2=_FileListToArray($Dir2)

If (Not IsArray($FilesList)) and (@Error=1) Then

MsgBox (0,"","No Files\Folders Found.")

Return

EndIf

$Files=_FileListToArray($Dir,"*",1)

$Files2=_FileListToArray($Dir2,"*",1)

If IsArray($Files ) Then

For $i=1 To $Files[0]

for $j=1 To $Files2[0]

$FilePath=$Dir&"\"&$Files[$i]

$FilePath2=$Dir&"\"&$Files2[$j]

If $FilePath==$FilePath2 Then

EndIf

Next

Next

EndIf

EndFunc

to get the image files from the directory ... But its no working properly,, Please check it what is the wrong?....Help is appreciated.

If you want to check binary content, you'll be better off using something like that:

Func CompareFilesBinaryContent($file1, $file2)
 
$resTxt = ""
 
$handle = FileOpen(FileGetShortNameV2($file1), 16)
$content1 = FileRead($handle)
FileClose($handle)
 
$handle = FileOpen(FileGetShortNameV2($file2), 16)
$content2 = FileRead($handle)
FileClose($handle)
 
$str_diff = StringCompareExV1($content1, $content2)
 
If $str_diff Then
$resTxt = "Files have different binary content."
$resTxt &= @CRLF & "File1='" & $file1 & "'"
$resTxt &= @CRLF & "File2='" & $file2 & "'"
EndIf
Return $resTxt
 
EndFunc   ;==>CompareFilesBinaryContent

As for isolating part of image that are similar from the ones that are different, this is difficult problem. A lot of people are working on it ( inclusing in people in Universities - pattern recognition, image similarities, etc. ), but I haven't stumbled on an easy to use/implement solution yet. Academia is on it. Developers are on it ( eg. http://www.codeproject.com/KB/GDI-plus/comparingimages.aspx ). Let us know if you have more luck.

On a more personal note, I started writing a C# application a couple years ago that would group pixels and and search for similarities but interrupted this project because I found an easier way to achieve what I needed: 1/ I compare bare binary content and then 2/ I swap the 2 images every second at the same place and I visually check for differences (works great even for very tiny differences).

Take care.

Note here is another similar work: if you can search for a pixel on the screen, then you can search for a given pixel in another image. The problems are somehow related.

Thanks for all reply.. I have another problem is to run the multiple application scripts one by one ..The application list is in treeview list .....Is there any solution to run the scripts one by one ...reply is appreciated..

As about compare images lokk here

As about your last question:

It's too vaque, you must be more exact to get help here.

[Mallikarjun]

Thanks for reply.. Ihave maked the scripts for application to execute...my problem is to find the application name in the list

and execute the perticular application one by one ..Plz reffer the attached file...

[Zedna]

What's the ClassNameNN of that control?

[Morthawt]

If you need to check if an image is the same, why not render the image on a GUI and use PixelChecksum to calculate a checksum of a pre-defined area? If the images are the same size and the part on the image to check is in the same place, then doing this method will give you a clear yes or no to if its different. Even if the location is different you may be able to intuit the location to search using PixelSearch and PixelGetColor to define the coordinates of an area that could be quantified each time yet may be in a different location on the screen perhaps.

[Mallikarjun]

Thanks for reply .... Please find the attached image for class and control information..

[Mallikarjun]

I am finding the apllication in the list by copying the text and comparing that text to the given application name

;copying the application name

$data= ClipGet()

Local $file=FileOpen($Appname, 1)

FileWrite($file,$data)

_FileReadToArray($file, $fdata)

$CountLines = _FileCountLines($file)

For $x = 1 to $CountLines Step 1

$sourcePath = $fdata[$x]

Next

If StringRegExp ($sourcePath, "AnimationApp", 0) == 1 Then

MsgBox(0, "yes", "i am")

EndIf

problem is to run the scripts one by one ...after finding the application....

[Mallikarjun]

Thanks to all.. i am running all my application in one script.....

If I didn't know better I would say that is the Eclipse code editor

Hi All,

I have some problem in this code

to compare the 2 directory images plz see bellow script....

Func ImgComp2()

Global $file1=_FileListToArray("C:Sdk_AutomationDatabaseWQVGA" & $mytext2 & "", "*.bmp", 1)

Global $file2=_FileListToArray("C:Sdk_AutomationOutputImagesWQVGA"& $mytext2 & "","*.bmp",1)

For $i=1 To UBound($file1)-1

$ram1=FileRead($file1[$i])

$ram2=FileRead($file2[$i])

;MsgBox(0, "", $file1[$i])

;MsgBox(0, "", $file2[$i])

If $ram1==$ram2 Then

Imglog2("ok")

;MsgBox(0, "", "ok")

Else

Imglog2("NG")

;MsgBox(0, "", "NG")

EndIf

Next

I am comparing 2 directory images one for updating the outputs but its not working properly plz check it once help should be apreciated...

Thanks in advance

Its comparing the images when i comparing the single images.

$ram1=FileRead("C:arjun1.bmp")

$ram2=FileRead("C:arjun2.bmp")

If $ram1==$ram2 Then

MsgBox(0, "", "good luck")

Else

MsgBox(0, "", "no")

EndIf

but the problem occurs to compare the multiple images.

help should be appreciated

thanks
