findContoursAsync function

Future<(Contours, Mat)> findContoursAsync(
  1. Mat src,
  2. int mode,
  3. int method
)

FindContours finds contours in a binary image.

Implementation

Future<(Contours contours, Mat hierarchy)> findContoursAsync(Mat src, int mode, int method) async =>
    cvRunAsync2(
      (callback) => cffi.FindContours_Async(src.ref, mode, method, callback),
      (c, p, p1) =>
          c.complete((Contours.fromPointer(p.cast<cvg.VecVecPoint>()), Mat.fromPointer(p1.cast<cvg.Mat>()))),
    );
