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 ShellSort algorithm. An extended function with additional functionality is available as SortATPAByMiddleEx.
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)];
SortATPAByMiddle(ATPA);
for i := 0 to High(ATPA) do
WriteLn(TPAToStr(ATPA[i]));
end.Output:
(1,1);(2,2) (1,6);(5,4);(1,5) (5,10)
