[request] want as feature: get the nearest point/region/image to a given point/region/image

This is a more general solution:

import math

# used by sorted, to calculate the distance to refLocation
# the sort function uses this value for sorting the list elements
def by_nearest(match):
  x = math.fabs(match.getCenter().x - refLocation.x)
  y = math.fabs(match.getCenter().y - refLocation.y)
  distance = int(math.sqrt(x * x + y * y))
  return distance

img = "some-image.png" # the image to look for

refLocation = Env.getMouseLocation() # the reference point

# use findAll(), to find all matches on screen
# and create the sorted list
sortedMatches = sorted(findAll(img), key=by_nearest)

# list contains the elements sorted by distance in ascending order
# hence the first element is the one we are looking for
sortedMatches[0].highlight(2)
