Checksum related code

Ok I'll start

Im looking for a code akin to the regular pixelchecksum function

That function will create a checksum based on the coords and step parameter you define

I would love a function to create a checksum based on irregular pixels in the coords

eg: _IrrPixelChecksum(200,200,210,210,6,9,13,22,40,55,78,90)

Whereby the red params are the pixels relative to coords first pixel in the 100 pixel rectangle area defined.

I would really appreciate seeing something like this, but alas the pixelchecksum function is inbuilt to autoit and I cant even study it to see if it could be modded (not that I could anyway) or would be allowed to

If this is not the kind of thing allowed here, please feel free to delete it

Can you explain a little differently? I take it you want to check only certain pixels. For example generate a check sum checking every other pixel.

OK i get it now. I'm gonna see if I can write a little function for you.

Normal pixelchecksum will create a checksum with a step value of a defined amount of pixels skipped

The optional step value like PixelChecksum(200,200,210,210,2) will only check every other pixel from left to right, top to bottom, if you use 3 it will check every third pixel

Im after a function where I can define the exact pixels it will use

Cheers for your reply

Give this a try. I wrote a function to do the task that you asked for. It however takes an array as the coords. It also requires the md5.au3 to generate checksum. Download

Very much appreciated my friend

Will have a look now

Working fine mate, thanks very much.

I'm supposing I could expand or deflate the array size, is this correct ?

Do you think their would be limitations to its elements ?

Yes you can change the size of the array just make sure it is has the same format as the one i used. For example , you could do dim $Array[10][2] and then you would have ten pixels to check.

I have improved the code to use the Crypt.au3 from the latest beta. Download

Wow, thanks matey.

Love the logic you done in this.

Excellent.

No problem. Glad to see the site getting some use. =)

Ahh, just noticed after this post

I thought I was checking 8 pixels, no wonder I wasent getting the results I expected

Are the groups of 2

$Array[0][0]=6
$Array[0][1]=9

$Array[1][0]=13
$Array[1][1]=22

$Array[2][0]=40
$Array[2][1]=55

$Array[3][0]=78
$Array[3][1]=90

Reletive coordinates in the rectangle ?

eg

$Array[0][0]=o
$Array[0][1]=0

Would be the first pixel (top left) in the rectangle ?

yes they are relative coordinates.
