Does anyone know how shades variations works?

[Makaule]

Hello all, i have 1 question again. Does anyone know, how shades variations works? For example PixelSearch may look for color + shades variation, so its possible to get similar colors. I am planing to make Image colors checker using GDI+, but as i had noticed, it dont have shades variation function. Thanks in advance for all your answers.

if it works identically to AHK then 0 means no variation at all from given color code (match must be exact color) and 255 marks all colors..

havent used this function yet in Autoit but its syntax looks identical

I am not sure,is my idea good or not, so i asked here. I think that its possible to add that "shade variation" to each of color, so i would get shaded color.

For Example:

I have RGB color [120] [193] [123];

I have shade 10;

So color which i need [120 +/- 10] [193 +/- 10] [123 +/- 10 ].

Am i wrong?

That is how I understand "shade-variation" as described in the help. You will need to ensure that the resulting values for R,B and G are within 0 to 255 though.

$Bright = [newc($r + $shade)][newc($b + $shade)][$newc($g + $shade)]
$dull = ....
Func newc($val)
 if $val < 0 then return 0
 if $val > 255 then return 255
 return $val
EndFunc

Ya, that's the same as i think. Seems that its working.
