Description
Sorts a given TPointArray TPA by distance from the origin (0, 0) using the fast ShellSort algorithm. An extended function with additional functionality is available as SortTPAEx.
Example
var TPA: TPointArray; begin TPA := [Point(2, 2), Point(0, 0), Point(5, 10), Point(0, 0)]; SortTPA(TPA); WriteLn(TPAToStr(TPA)); end.
Output:
(0,0);(0,0);(2,2);(5,10)
