Pixel search and shade-variation

[matrix10657]

Can someone please explain to me how to use the shade-variation feature in the Pixelsearch command. For example I have a hex color that is as follows. 0xCFC3C2 , however, the color can change but the hex code always has 0xC(x)C(x)C(x) (with X being a random letter or number). Is there a way I can get pixelsearch to detect a color with 0xC(x)C(x)C(x) in it?

The shade variation works by putting a number into its parameter from 1 to 255. The higher the number, the higher the shade variation. So, if the number is 1, it will check to see if a pixel color exists with a shade variation higher and lower for each of the RBG colors. If the number is 10, it will check to see if there is a shade of color higher or lower by 10 shades.

To check for a pixel 0xC?C?C?

for $y = $top to $bottom
     for $x = $left to $right
          $c=pixelgetcolor($x,$y)
          $cm = bitand($c,0xf0f0f0)
          if $cm = 0xC0C0C0 then
               $foundone = true
               exitloop[2]
          endif
     next
next
