Definition

procedure SortTPAEx(var TPA: TPointArray; const Point: TPoint);

Availability

SCAR Divi 3.28 > Current

Aliases

  • TPASortEx (SCAR Divi 3.26 > 3.37)

Notes

  • Before 3.37.02, this function threw exceptions for points with large coordinate values (over +/- 30000 in either direction from 0)

Description

Sorts a given TPointArray TPA by distance from a given TPoint Point using the fast ShellSort algorithm.

Example

var
  TPA: TPointArray;

begin
  TPA := [Point(2, 2), Point(0, 0), Point(5, 10), Point(0, 0)];
  SortTPAEx(TPA, Point(3, 3));
  WriteLn(TPAToStr(TPA));
end.

Output:

(2,2);(0,0);(0,0);(5,10)
