Create Markup Leaders

To create a markup leader:

Create an object of the OdPrcMarkupLeader class:


          OdPrcMarkupLeaderPtr leader = OdPrcMarkupLeader::createObject();

Set graphical information for the leader:


          OdPrcGraphics graph;
          leader->graphics() = graph;

Create a tessellation object for the markup leader and fill the coordinates and codes array with color and a polyline entity (based on two points), and add tessellation to the markup leader:


          OdPrcMarkupTessPtr mTess = OdPrcMarkupTess::createObject();
          mTess->setLabel("test");
          OdUInt32Array code_arr;
          mTess->coordinates().push_back(-1.9);
          mTess->coordinates().push_back(-1);
          mTess->coordinates().push_back(0);
          mTess->coordinates().push_back(-3.7);
          mTess->coordinates().push_back(-3.8);
          mTess->coordinates().push_back(0);

          code_arr.push_back(90177537); // Color 
          code_arr.push_back(0);
          code_arr.push_back(0);
          code_arr.push_back(0);//PolyLine
          code_arr.push_back(6);
          mTess->codes() = code_arr;
          leader->tessellation() = mTess;

See Create a Markup Tessellation for details about the previous code fragment.

For additional information about working with markup tessellation, see Work with Markup Tessellation.

Creating markup leaders is illustrated in the OdPrcCreate sample application.
