Quick question

Recommended Posts

Just wondering how can I find out of a certain color pixel is within a certain # of pixels of another color? I'm using the pixel search function and have been researching and trying but to no avail. If someone can point me in the right direction or offer any sort of help that'd be greatly appreciated, thanks! 

Edit: To clarify, this is what i am attempting:

If PIXEL1 is <= 5 pixels FROM PIXEL2

If you have the location of the 2 pixels then simple maths should give you the answer:

If Abs($iX_1 - $iX_2) <= 5 And Abs($iY_1 - $iY_2) <= 5 Then
    ; Success
    ; Fail
Using the absolute difference is a pretty standard method for determining the "nearness" of linear values. :)

OTOH if you want to determine whether a pixel lies in the disk whose radius is your threshold (euclidean distance), you'll have to test otherwise:

Local $x1 = 23, $y1 = 487
Local $x2 = 24, $y2 = 490
Local $x3 = 21, $y3 = 484

ConsoleWrite("Distance between pixel 1 and pixel 2 = " & _Dist($x1, $y1, $x2, $y2) & @LF)
ConsoleWrite("Distance between pixel 1 and pixel 3 = " & _Dist($x1, $y1, $x3, $y3) & @LF)
ConsoleWrite("Distance between pixel 2 and pixel 3 = " & _Dist($x2, $y2, $x3, $y3) & @LF)

Func _Dist($x1, $y1, $x2, $y2)
    Return Sqrt(($x1 - $x2) ^ 2 + ($y1 - $y2) ^ 2)
