Definition
function SplitTPA(const TPA: TPointArray; const Dist: Integer): T2DPointArray;
Availability
SCAR Divi 3.27 > Current
- Contained a bug in 3.26 that caused the resulting 2d array to contain additional wrong arrays.

Description
This function splits a given TPointArray TPA into separate TPointArrays by grouping together the points that are within a given distance Dist from each other. The function returns a T2DPointArray containing all the resulting TPointArrays. An extended function with additional functionality is available as SplitTPAEx.
Example
var
i: Integer;
TPA: TPointArray;
ATPA: T2DPointArray;
begin
TPA := [Point(0, 0), Point(2, 6), Point(1, 2), Point(1, 1)];
ATPA := SplitTPA(TPA, 2);
for i := Low(ATPA) to High(ATPA) do
WriteLn(TPAToStr(ATPA[i]));
end.Output:
(0,0);(1,1);(1,2) (2,6)
