Description

This function determines the arithmetic mean of all x and y coordinates in the given TPointArray TPA, and returns this as a TPoint (rounded down). An extended function with additional functionality is available as TPAMiddleEx.

Example

var
  TPA: TPointArray;
  MiddlePoint: TPoint;
  
begin
  TPA := [Point(0, 0), Point(2, 2), Point(5, 10)];
  MiddlePoint := TPAMiddle(TPA);
  WriteLn('Middle-Point(' + IntToStr(MiddlePoint.x) + ',' + IntToStr(MiddlePoint.y) + ')');
end.

Output:

Middle-Point(2,4)
