Code example to create diagram image

Jump start your BPMN capable solution in minutes!

Sample code to read BPMN file and save it as an image:

Model model = BPMN.Model.Read("B.2.0.bpmn");
Image img = model.GetImage(0, 2.0f);
img.Save("B.2.0.png", ImageFormat.Png);

Code example to create new diagram

Sample code to create a new BPMN model and write it to file:

    public static bool Create(string fileName)
    {
      Editor editor = new Editor();
      editor.Create("BPMN Model", "User");

      string id1 = editor.AddEvent(null, null, "Start Event", EventType.Start, EventTrigger.None, EventRole.None);
      string id2 = editor.AddActivity(null, "Task 1", ActivityType.Task, ActivityMarker.None, TaskType.User, null);
      string id3 = editor.AddActivity(null, "Task 2", ActivityType.Task, ActivityMarker.None, TaskType.Manual, null);
      string id4 = editor.AddActivity(null, "Task 3", ActivityType.Task, ActivityMarker.None, TaskType.Service, null);
      string id5 = editor.AddEvent(null, null, "End Event", EventType.End, EventTrigger.None, EventRole.None);
      string id7 = editor.AddFlow(null, null, id1, id2, null, FlowType.Sequence, null, false, FlowDirection.None);
      string id8 = editor.AddFlow(null, null, id2, id3, null, FlowType.Sequence, null, false, FlowDirection.None);
      string id9 = editor.AddFlow(null, null, id3, id4, null, FlowType.Sequence, null, false, FlowDirection.None);
      string id10 = editor.AddFlow(null, null, id4, id5, null, FlowType.Sequence, null, false, FlowDirection.None);

      string id = editor.AddDiagram("Test 1", 96);

      Shape shape = new Shape();
      Rectangle rect = new Rectangle(10, 10, 30, 30);
      shape.Bounds = new List<Rectangle>();
      shape.Bounds.Add(rect);
      shape.ElementRef = id1;
      editor.AddShape(id, shape);

      rect.Width = 70;
      rect.Offset(60, 0);
      shape.Bounds[0] = rect;
      shape.ElementRef = id2;
      editor.AddShape(id, shape);

      rect.Offset(100, 0);
      shape.Bounds[0] = rect;
      shape.ElementRef = id3;
      editor.AddShape(id, shape);

      rect.Offset(100, 0);
      shape.Bounds[0] = rect;
      shape.ElementRef = id4;
      editor.AddShape(id, shape);

      rect.Width = 30;
      rect.Offset(100, 0);
      shape.Bounds[0] = rect;
      shape.ElementRef = id5;
      editor.AddShape(id, shape);

      List<Point> points = new List<Point>();
      points.Add(new Point()); points.Add(new Point());
      points[0] = new Point(40, 25); points[1] = new Point(70, 25);
      Edge edge = new Edge() { ElementRef = id7, Points = points }; 
      editor.AddEdge(id, edge);

      points[0] = new Point(140, 25); points[1] = new Point(170, 25);
      edge = new Edge() { ElementRef = id8, Points = points }; 
      editor.AddEdge(id, edge);

      points[0] = new Point(240, 25); points[1] = new Point(270, 25);
      edge = new Edge() { ElementRef = id9, Points = points }; 
      editor.AddEdge(id, edge);

      points[0] = new Point(340, 25); points[1] = new Point(370, 25);
      edge = new Edge() { ElementRef = id10, Points = points }; 
      editor.AddEdge(id, edge);

      return editor.Save(fileName);
    }
