lineAsync function

Future<Mat> lineAsync(
  1. InputOutputArray img,
  2. Point pt1,
  3. Point pt2,
  4. Scalar color, {
  5. int thickness = 1,
  6. int lineType = LINE_8,
  7. int shift = 0,
})

Line draws a line segment connecting two points.

Implementation

Future<Mat> lineAsync(
  InputOutputArray img,
  Point pt1,
  Point pt2,
  Scalar color, {
  int thickness = 1,
  int lineType = LINE_8,
  int shift = 0,
}) async =>
    cvRunAsync0(
      (callback) =>
          cffi.Line_Async(img.ref, pt1.ref, pt2.ref, color.ref, thickness, lineType, shift, callback),
      (completer) => completer.complete(img),
    );
