我试图检测矩形内的矩形AForge.我已经成功确定Rectangles但无法找到circles内部Rectangle.如何找到另一个形状内的形状AForge.
string strPath = Server.MapPath("~/Recipt001.png");
Bitmap myBitmap = new Bitmap(strPath);
//Some filters Grayscale, invert, threshold
//Blod Filtering
BlobCounter blobCounter = new BlobCounter();
blobCounter.ProcessImage(temp);
blobCounter.ObjectsOrder = ObjectsOrder.YX;
blobCounter.FilterBlobs = true;
Blob[] blobs = blobCounter.GetObjectsInformation();
Graphics g = Graphics.FromImage(myBitmap);
Pen redPen = new Pen(Color.Red, 2);
SimpleShapeChecker shapeChecker = new SimpleShapeChecker();
// dictionary of color to highlight different shapes
Dictionary<PolygonSubType, Color> colors = new Dictionary<PolygonSubType, Color>();
colors.Add(PolygonSubType.Unknown, Color.White);
colors.Add(PolygonSubType.Trapezoid, Color.Orange);
colors.Add(PolygonSubType.Parallelogram, Color.Red);
colors.Add(PolygonSubType.Rectangle, …我想转换List成json.结构如下:
public class ResourceCollection
{
public string Name { get; set; }
public Resources Resources { get; set;}
}
public class Resources
{
public string en { get; set; }
}
List<ResourceCollection> liResourceName = new List<ResourceCollection>();
//section to add the objects in list
string json = JsonConvert.SerializeObject(liResourceName, Newtonsoft.Json.Formatting.Indented);
这产生了预期的结果:
[
{
"Name": "Hello",
"Resources":
{
"en": "Hello"
}
},
{
"Name": "World",
"Resources":
{
"en": "World"

http_requests_in_progress
它应该是这样的：

我已经像这样启动了服务器：
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
try { app.UseMetricServer("/metrics"); app.UseHttpMetrics(); } catch (Exception ex) { }
}
我安装了nuget软件包，然后安装了引导程序。现在我有文件夹

containing bootstrap css files
Scripts
containing .js files
在“母版页”页眉中，我已经这样包含了它
<script type="text/javascript" src="~/Scripts/bootstrap.js"></script>
<script type="text/javascript" src="~/Scripts/bootstrap.min.js"></script>
<script type="text/javascript" src="~/Scripts/jquery-1.9.1.js"></script>
