What data makes of a checksum?

[LeBot]

Hello,

I want to save a set of about 10 pixel checksums to compare to the screen when running the script.

I would like to know if there's any way i can know the "output" of a checksum so i can save it as a starting variable in a script.

If is not possible what would you recommed?

I'm not sure if i made me clear

Thanks

Just create an image with the pixels, display it and let AutoIt calculate the checksum

Yes that would work, but is there any way I don't have to do that everytime i run the script?

And thanks for the fast reply

Hello LeBot,

First, Welcome to the AutoIt Forums!

What ProgAndy suggested, is what your asking. In Example:

Local $checksumA = PixelChecksum(100, 100, 200, 200)
Local $checksumB = PixelChecksum(300, 300, 400, 400)

;Do something
;Do something
;Do something
If PixelChecksum(100, 100, 200, 200) = $checksumA Then
    ;Do something
    ;Do something
EndIf
;Do something
;Do something
If PixelChecksum(300, 300, 400, 400) = $checksumB Then
    ;Do something
    ;Do something
EndIf

Another suggestion, could be to create another script that will gather the initial checksum values and store them in a file, that your second script can compare against.

You have to do it once, output the values (e.g. ConsoleWrite) and insert them into your main script.
