WPF使用Halcon打开图片

1、新建WPF工程，在解决方案资源管理器中选中当前工程项目，鼠标右击，弹出右键菜单，移动鼠标点击【属性】，弹出属性界面，选择【生成】项，勾选中【允许不安全代码】

2、添加引用halcondotnet.dll，下载halcondotnet.dll、halcon.dll、halcondotnet.xml、halconxl.dll到生成目录下。并准备一张RGB图片，重命名为"1.jpeg"

3、在MainWindow.xaml页面中添加如下代码：

<Window x:Class="HalconTest.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350     <Grid Name="mygrid">
       
    </Grid>
</Window>

4、在MainWindow.xaml.cs页面中添加如下代码：

using HalconDotNet;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace HalconTest

{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public unsafe MainWindow()
        {
            InitializeComponent();
            HObject image;
            HOperatorSet.ReadImage(out image,  "1.jpeg");

            HImage h_image = new HImage();

            //HTuple pointer;
            HTuple t;
            HTuple w;
            HTuple h;
            HTuple pointerRed;
            HTuple pointerGreen;
            HTuple pointerBlue;
            HOperatorSet.GetImagePointer3(image, out pointerRed, out pointerGreen, out pointerBlue, out t, out w, out h);
            h_image.GenImage3(t, w, h, pointerRed, pointerGreen, pointerBlue);
            string t2;
            int w2;
            int h2;
            IntPtr pr, pg, pb;
            h_image.GetImagePointer3(out pr, out pg, out pb, out t2, out w2, out h2);
            int len = w * h;
            byte[] datar = new byte[len];
            byte[] datag = new byte[len];
            byte[] datab = new byte[len];
            Marshal.Copy(pr, datar, 0, len);
            Marshal.Copy(pg, datag, 0, len);
            Marshal.Copy(pb, datab, 0, len);
            h_image.Dispose();
            byte[] data = new byte[len * 3];
            fixed (byte* bp = data, bbp = datab, brp = datar, bgp = datag)
            {
                byte* b = bp;
                byte* bb = bbp;
                byte* bg = bgp;
                byte* br = brp;
                for (int i = 0; i < len; i++)
                {
                    *b = *bb; b++; bb++;
                    *b = *bg; b++; bg++;
                    *b = *br; b++; br++;
                }
            }
            WriteableBitmap wb = new WriteableBitmap(w, h, 96, 96, System.Windows.Media.PixelFormats.Bgr24, null);
            wb.WritePixels(new System.Windows.Int32Rect(0, 0, w, h), data, w * 3, 0);
            mygrid.Background = new System.Windows.Media.ImageBrush(wb);
        }

    }

}

5、编译代码，生成解决方案。编译成功后，按F5执行。出现图像画面。
