OpenCVSharpSample04WinForms

1、 Create a winform project

Add a in the interface flowLayoutPanel1, And please change it to the window size

2、 add to opencvsharp4

3、 stay form1.cs Add opencvsharp quote

using OpenCvSharp;
using OpenCvSharp.Extensions;

4、 Modify the code according to the example

Found in editing , Error on this line

pictureBoxIpl = new OpenCvSharp.UserInterface.PictureBoxIpl

The study found that ,opencvSharp3 Contains userinterface, But in 4 Not in China , Delete this function , compile , The system runs as follows ：

This program demonstrates how to display... On the interface mat graphics

The main idea is

（1） Using functions BitmapConverter.ToBitmap() Turn the picture into bmp

（2） take bmp Load into PictureBox

（3） take PictureBox Add to flowLayoutPanel1 Inside

The main codes are as follows ：

Bitmap bitmap;
            using (var iplImage = new Mat(@"..\..\Images\Penguin.png", ImreadModes.AnyDepth | ImreadModes.AnyColor))
            {
                bitmap = iplImage.ToBitmap(); // BitmapConverter.ToBitmap()
            }

            var pictureBox = new PictureBox
            {
                Image = bitmap,
                ClientSize = bitmap.Size
            };

            //How to redraw:
            //iplImage.ToBitmap(dst: (Bitmap)pictureBox.Image);

            flowLayoutPanel1.Controls.Add(pictureBox);
