Definition
procedure SortATPAByFirstEx(var ATPA: T2DPointArray; const Point: TPoint);
Availability
SCAR Divi 3.28 > Current
Description
Sorts the given T2DPointArray ATPA by the distance of the first point in every non-empty subarray to the TPoint given in Point using the fast ShellSort algorithm. Empty subarrays are placed at the start of the array.
Example
var
ATPA: T2DPointArray;
i: Integer;
begin
SetLength(ATPA, 3);
ATPA[0] := [Point(1, 6), Point(5, 4), Point(1, 5)];
ATPA[1] := [Point(1, 1), Point(2, 2)];
ATPA[2] := [Point(5, 10)];
SortATPAByFirstEx(ATPA, Point(5, 5));
for i := 0 to High(ATPA) do
WriteLn(TPAToStr(ATPA[i]));
end.Output:
(1,6);(5,4);(1,5) (5,10) (1,1);(2,2)
