Definition

procedure TPAFilterBoxes(var TPA: TPointArray; const Boxes: TBoxArray);

Availability

SCAR Divi 3.25 > Current

Description

Filters a TPointArray TPA by removing all included coordinates that fall within the bounds of any of the boxes specified in the TBoxArray Boxes.

Example

var
  TPA: TPointArray;
  TBA: TBoxArray;

begin
  TPA := [Point(0, 0), Point(2, 2), Point(2, 3), Point(5, 10)];
  TBA := [IntToBox(0, 0, 2, 2)];
  WriteLn('Unfiltered TPointArray: ' + TPAToStr(TPA));
  TPAFilterBoxes(TPA, TBA);
  WriteLn('Filtered TPointArray: ' + TPAToStr(TPA));
end.

Output:

Unfiltered TPointArray: (0,0);(2,2);(2,3);(5,10)
Filtered TPointArray: (2,3);(5,10)
