Description
This function inverts a given TPointArray TPA by reversing the order of the coordinates contained in within it.
Example
var
TPA: TPointArray;
begin
TPA := [Point(0, 0), Point(2, 2), Point(5, 10)];
InvertTPA(TPA);
WriteLn('TPointArray: ' + TPAToStr(TPA));
end.Output:
TPointArray: (5,10);(2,2);(0,0)
