This function determines the center point of a given TPointArray TPA by calculating the averages of the x and y coordinates and returns them in x and y. The function returns true if the given TPointArray TPA contains 1 or more values.

Example

var
  TPA: TPointArray;
  x, y: Integer;
  
begin
  TPA := [Point(0, 0), Point(2, 2), Point(5, 10)];
  if TPAMiddleEx(TPA, x, y) then
    WriteLn('Middle-Point(' + IntToStr(x) + ',' + IntToStr(y) + ')');
end.

Output:
