Description
This function splits a given TPointArray TPA into separate TPointArrays by grouping together the points that are within a given distance from each other. The distance is given separately for the x and y components of the points in XDist and YDist. The function returns a T2DPointArray containing all the resulting TPointArrays.
Example
var
i: Integer;
TPA: TPointArray;
ATPA: T2DPointArray;
begin
TPA := [Point(0, 0), Point(2, 6), Point(1, 2), Point(1, 1)];
ATPA := SplitTPAEx(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)
