We have got image 100×100 pixels. In this image red line is a path. When i parse this image to pixel colors i get red pixel in random order (in fact i get pixels from image line by line from top to bottom). But i want get a list of ordered dots of the path from point A to point B. How to do it.

example of path in image

This function gets pixel with red color (python language):

def getRoad(imgPng) -> list:
    img = Image.open(imgPng)
    pix = img.load()
    width, height = img.size

    x = 0
    y = 0
    road = []

    for y in range(BORDER_OFFSET, height-BORDER_OFFSET, STEP):
        for x in range(BORDER_OFFSET, width-BORDER_OFFSET, STEP):
            color = pix[x, y]
            if (COLOR_ROAD[0]-7 <= color[0] <= COLOR_ROAD[0]+7 and 
            COLOR_ROAD[1]-7 <= color[1] <= COLOR_ROAD[1]+7 and
            COLOR_ROAD[2]-7 <= color[2] <= COLOR_ROAD[2]+7):
                road.append((x, y))

    # print(len(road))
    return road
