Description

This function chains all TPoints that are within a certain distance from each other together into individual TPointArrays. The distance is given separately for the x and y components of the points.

Example

var
  i: Integer;
  TPA: TPointArray;
  ATPA: T2DPointArray;

begin
  TPA := [Point(0, 0), Point(2, 6), Point(1, 2), Point(1, 1)];
  ATPA := TPAChainEx(TPA, 0, 1);
  for i := Low(ATPA) to High(ATPA) do
    WriteLn(TPAToStr(ATPA[i]));
end.

Output:

(0,0)
(1,1);(1,2)
(2,6)
