==Description==
 
Sorts the given [[T2DPointArray]] '''ATPA''' by the distance of the middle of the points calculated with [[TPAMiddle]] to the origin (0,0) using the fast [http://en.wikipedia.org/wiki/Shell_sort ShellSort] algorithm. An extended function with additional functionality is available as [[SortATPAByMiddleEx]].
 
 
 
==Example==
 
<source lang="scar">
 
var
 
  ATPA: T2DPointArray;
 
  i: Integer;
 
 
 
begin
 
  SetLength(ATPA, 3);
 
  ATPA[0] := [Point(1, 6), Point(5, 4), Point(1, 5)];
 
  ATPA[1] := [Point(1, 1), Point(2, 2)];
 
  ATPA[2] := [Point(5, 10)];
 
  SortATPAByMiddle(ATPA);
 
  for i := 0 to High(ATPA) do
 
    WriteLn(TPAToStr(ATPA[i]));
 
end.
 
</source>
 
 
 
Output:
 
(1,1);(2,2)
 
(1,6);(5,4);(1,5)
 
(5,10)
