Hi,  I want to know if there exists a way to speed up this process? Local $update[50][50] $tStart = TimerInit() For $x = 493 To 529 Step 1 For $y = 263 To 271 Step 1 $Color = PixelGetColor($x, $y) $p1 = $x - 493 $p2 = $y - 263 $update[$p1][$p2] = $Color Next Next MsgBox(0, "t", TimerDiff($tStart)) $update = 0
