TIEVisionQRCode

Declaration

TIEVisionQRCode = interface(TIEVisionBase)

An interface representing one detected QR code.
getCorner returns the four vertices of the code quadrangle, so the outline can be drawn when the symbol is rotated or skewed.


Note: This is a QR code, not a Data Matrix symbol.

Example

var
  codes: TIEVisionVectorObjRef;
  qr: TIEVisionQRCode;
  i: Integer;
begin
  codes := IEVisionLib.createQRCodeDetector().detect(ImageEnView1.IEBitmap.GetIEVisionImage(), IEVisionRect(0, 0, 0, 0));
  for i := 0 to codes.size() - 1 do
  begin
    qr := TIEVisionQRCode( codes.getObj(i) );
    Memo1.Lines.Add(qr.getData().c_str());
  end;
end;
