Description

Sorts the given T2DPointArray ATPA by the distance of the middle of the points calculated with TPAMiddle to the TPoint given in Point using the fast ShellSort algorithm.

Example

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)];
  SortATPAByMiddleEx(ATPA, Point(5, 5));
  for i := 0 to High(ATPA) do
    WriteLn(TPAToStr(ATPA[i]));
end.

Output:

(1,6);(5,4);(1,5)
(5,10)
(1,1);(2,2)
