Description
Deletes the TPoint at a given position Index in a given TPointArray TPA and returns the deleted value. If the index is outside of the array bounds, nothing happens.
Example
var TPA: TPointArray; p: TPoint; begin TPA := [Point(0, 0), Point(2, 2), Point(5, 10)]; p := TPADelete(TPA, 1); WriteLn(TPAToStr(TPA)); WriteLn(IntToStr(p.X) + ',' + IntToStr(p.y)); end.
Output:
(0,0);(5,10) 2,2
