Example

procedure TMainForm.Button2Click(Sender: TObject);
var
  image, templ, map: TIEVisionImage;
  rect: TIEVisionRect;
begin
  ImageEnVect1.RemoveAllObjects();

  // get image to search
  image := ImageEnVect1.IEBitmap.GetIEVisionImage();

  // get the template image to find
  templ := IEVSource.IEBitmap.GetIEVisionImage();

  // perform template searching
  rect := image.matchTemplate(templ, TIEVisionTemplateMatchMethod(ComboBox1.ItemIndex));

  // draw a red box around the found rectangle
  ImageEnVect1.ObjPenWidth[-1] := 3;
  ImageEnVect1.AddNewObject(iekBOX, IEVisionRectToTRect(rect), clRed);

  // fill the resulting map
  map := image.matchTemplateAsMap(templ, TIEVisionTemplateMatchMethod(ComboBox1.ItemIndex));
  ImageEnVect2.IEBitmap.AssignIEVisionImage(map);
  ImageEnVect2.Update();
