Array help

[Regency]

I found a udf somone sent me, and it uses a function they wrote.

The udf uses arrays and i tried to read them and think about how i would go about doing what i wanted and dont understand the whole array things so i am at a loss.

So what i am trying to do is understand how i would be able to save the specific cords of the place i want it to search in the code and have it compare it to a already calculated number of pixels in the area and figure out which amount of pixels it matchs,

Like in area 100,100 there are 45 pixels of the color Pink (hex codes used), and this script looks in that area and finds 10 pink, so ir compares it to the base values i have set up and now i know that picture it was searching at 100,100 is actually color blue with pink underlaying.

If you dont understand post and i can try and explain

UDF

;=================================   PixelFindAll   ==============================
; Function Name:    _PixelFindAll_Compare
; Description:    Finds all instances of a pixel within a given area and returns array with Total and all locations X and Y.
;                       Compare allows you to skip pixels within a given distance to each other.
; Requires:                         None
; Parameters:       $Pixel          Colour value of pixel to find (in decimal or hex).
;                   $XDist          Horizontal distance from found pixel to skip before continueing search (moving right)
;                   $YDist          Vertical distance from found pixel to skip before continueing search (moving down)
;                   $sv             Shade Varience
;                   $SB_l           left coordinate of total area to search. Default is 0 (far left side of screen)
;                   $SB_t           top coordinate of total area to search. Default is 0 (top most Side of screen)
;                   $SB_r           Right coordinate of total area to search. Default is @DesktopWidth (Far Right side of screen)
;                   $SB_b           Bottom coordinate of total area to search. Default is @DesktopHeight (Bottom most side of screen)
; Syntax:         _PixelFindAll($pixel, $XDist, $YDist[, $sv, $SB_l, $SB_t, $SB_r, $SB_b])
; Author(s):        ofLight
; Returns:      $Array[0][0] = 0 on failure, $Array on success
