Color Variance?

[riceking 0]

I know some functions like PixelSearch has an optional variance (parameter? don't know the word). Anyways there is a place where you can put the variance. my question is: what the heck is variance, I know it has to be between 0 and 255. I'm guessing that the number you put for variance(10) will allow the color to change by 10 on each RGB scale. Not sure.

I'd wager it would be the +/- value range of the RGB components that would qualify for the PixelSearch.

I.E. with a search parameter of RGB 100,90,80 and a variance of 5, the color values that would qualify would be colors whose RGB components are of the following ranges: R 100 + or - 5, B 90 + or - 5, G 80 + or - 5.

That's seems to be a good guess, is it written anywhere in the help files, I couldn't find it.

If it was in the helpfile it would be under PixelSearch() as that is the only function having that parameter.

it isn't if youre wondering. I'm supprised it isn't explained

"A number between 0 and 255 to indicate the allowed number of shades of variation of the red, green, and blue components of the colour. Default is 0 (exact match)."

Now the question is this: can everybody noob or not understand that? I can but I can see how someone new to AutoIt might not.

Well, if they didn't know it before, if they are smart enough to use the search, they'll know it now.
