Cannot convert from OpenCvSharp.Point2f[] to OpenCvSharp.Mat<OpenCvSharp.Point2f>

[Dcruise546]

Summary of your issue

Could not find any methods that will let me convert the Point2f[] to Mat<Point2f>

A little background: I am trying to move from OpenCvSharp 3 to OpencvSharp 4. Therefore changing every instance of MatOfPoint2f to Mat<Point2f>.

Environment

Visual Studio 2019 Windows 10 .Net Framework 4.7.2

Example code:

I only pasted the part of the code and please do not care about the approach here! The variable Point2f[] is of my interest here.

List<Mat<Point2f>> imagePoints = new List<Mat<Point2f>>
Point2f[] corners = null;
var foundCorners = Cv2.FindChessboardCorners(
                                calibrationImage,
                                new Size(CalibrationPatternSize.X, CalibrationPatternSize.Y),
                                out corners,
                                ChessboardFlags.AdaptiveThresh);
var subPixelCorners = Cv2.CornerSubPix(calibrationImage, corners, new Size(1, 1), new Size(-1, -1), criteria);
imagePoints.Add(corners.Clone()); // This is where I get the error
corners.Dispose(); // Obviously an error here as well

What did you intend to be?

Either I wish to know a workaround or a simpler way to convert the variable 'corners' to Mat<Point2f> and add it to my list.

Something like this:

var matCorners = new Mat(corners.Length, 1, MatType.CV_32FC2, corners);

No need to dispose corners it's an array of structs.
