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 { /// /// MainWindow.xaml 的交互逻辑 /// 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); } } }
