Check a sequence of pixels

[StiveMox]

How to know if this image there are the following colors: ff0f0f, ff860f, 601b5c.

And return if the image is valid or not.

Recalling that the image is only valid if there cited these colors.

The image is in a GUI or in a file?

case GUI

PixelGetColor() function will do the job

case File

What format is the file

case BMP

Theres a BMP library somewhere in the forum that is very simply and use only AutoIt native Functions

case else

You will need some GDI+ functions for that but again this was already done somewhere in the forum

Return "done"

This is a file in jpg.

Sometimes a picture is normal, which has several pixels.

I think it nescessário pixelsearch use to find these colors in the photo.

But the problem is how to find more than one pixel with Pixelsearch.

StiveMox,

Search for the first colour. If found, search for the second. If found, search for the third. And so on.....

If any colour is not found, you do not have a valid image.

StiveMox,

So does it work?

What kind of question is that? Have you tried it yourself?

And next time you want to post code, just put [autoit] before and [/autoit] after the code so it appears in a nice box here on the forum.

I was unaware of the code tags to place on the forum. Sorry.Yes I'm trying to do, but I'm beginner and I need help.

if PixelSearch($left, $top, $right, $bottom, $color1) and PixelSearch($left, $top, $right, $bottom, $color2) and PixelSearch($left, $top, $right, $bottom, $color1) Then
            MsgBox(0, "Validation", "Image valid!")
        EndIf

I recomend to Post the entire script, because that fragment never will works beacuse the variables $left, $right, etc never were defined in the script.

Look in the help file the explain of the function and see the example to look how it work..

another function that you can use is PixelGetColor()

If you want to use PixelSearch then you have to define the parameters of the box where the function have to search for.

StiveMox,

That will not work because PixelSearch returns an array (look in the Help file for more details). I would do something like this untested):

; The return will be the result of the test
$fResult = _TestImage($left, $top, $right, $bottom, $color1, $color2, $color3)

Func _TestImage($left, $top, $right, $bottom, $color1, $color2, $color3)
    ; Look for first colour
    PixelSearch($left, $top, $right, $bottom, $color1)
    ; If not found then return false
    If @error Then Return False
    ; Look for second colour
    PixelSearch($left, $top, $right, $bottom, $color2)
    If @error Then Return False
    ; Look for third colour
    PixelSearch($left, $top, $right, $bottom, $color3)
    If @error Then Return False
    ; We must have found all 3 so return true
    Return True
EndFunc

Try that and see how you get on.

;Check if the image exists some colors required.

While 1
    Sleep(1)
WEnd

HotKeySet("{q}", "start") ;start the image verification
HotKeySet("{w}", "stop") ;close the soft

Func start()

    Dim $coord[4] = [306, 357, 677, 535]
    Dim $colors[3] = [0xff0f0f, 0xff860f, 0x601b5c]

    While 2
    
        If PixelSearch($coord[0], $coord[1], $coord[2], $coord[3], $colors[0]) and PixelSearch($coord[0], $coord[1], $coord[2], $coord[3], $colors[1]) Then
        MsgBox(0, "Image verification", "The image is valid!")
        EndIf
    WEnd
EndFunc

Func stop()
    Exit
EndFunc

@Melba23

I will try. Thanks.
