I am trying to make a small script to scan pixels (using PixelGetColor) in a particular region and output them into a file so that I may eventually get to some pattern recognition abilities.

I had a script like this that was working fine which scanned a small area in a black and white picture and output it as a simple ascii version of only 0 and X, 0 if it was white, X if it was black. After I made some simple modifications to it, the script wouldn't work anymore, and even after I simplified it, I couldn't get it to make even a simple scan.

When I scan a small region with only black and white pixels, and output the colors read into a text file, I get colors other than black and white.
And it isn't an issue of my switching programs before the scanning is done so that it would accidentally read the desktop. I keep the picture on the side and can see the file as it is created on the desktop.

Here is the script. It scans a 100x100 pixel region with the current mouse position at the top left corner of that region. Is there something wrong with the script or my computer?

I ran this code on my all black desktop and the file is black until line 975 then has some other colors, and the last 90% of the file is white consistiently when I'm not seeing any white on the screen.

See below for the entire file

I have been working with PixelGetColor for 3 days now with intermittent problems that I just cannot explain. I keep rewriting the same code to get 100 pixels square from the screen at mouse cursor, then draw 100 colored letters in a GUI window.

Then I mouseover one of my taskbar icons and try to "scan" it in.

The best I've gotten is 10 pixels in either direction.

Maybe its because I'm not incrementing at the correct stages in the loop.

My last attempt was little short of 100 different variables in a loop

I would post my code, but it's not doing so well anymore


%color% = MyArray%i%_%j%
Gui, Add, Text,c%color% X%xLocation% Y%yLocation% ,p
If %ErrorLevel% = "it didn't work"
{
Uninstall AHK
Format C:\
Bathtub := Hairdryer + User
}
else
Go to bed

I solved it with someone elses code posted here
