Camera

First, you have to import Layout class:

      import com.infairy.cocina.SDK.Layout.Layout;
      import com.infairy.cocina.SDK.Layout.LayoutCamera;
      

Then, get Layout service

        Layout layout=(Layout)Tools.getService(context, Layout.class.getName(), "(FUNCTION=LAYOUT)");
      

Next, create layout tag and get LayoutID for other layout object used purpose:

            LayoutTag ltag=new LayoutTag();

            ltag.backgroundImage="img/background.png";
            ltag.bundleID=BundleID;
            ltag.LayoutHeight=450;
            ltag.LayoutWidth=800;
            ltag.title="My App";
            /*
             * Create layout tag and get layout id for other layout object use
             */
            LayoutID=layout.createUI(this, ltag);
      

Nex, create camera layout object:

          LayoutCamera lcam=new LayoutCamera();
          lcam.LayoutID=LayoutID;
          lcam.left=172;
          lcam.top=48;
          lcam.width=491;
          lcam.height=331;
          lcam.CameraID=cameraId;
          /*
           * Create camera layout object
           */
          cameraID=layout.createUI(this, lcam);
          lcam=null;

          
      

The Camera layout can be clicked by users, you just need to do defined the key value:

          lcam.key=device.DEVICE_OPERATION_USER_DEFINED_0;
      

"DEVICE_OPERATION_USER_DEFINED_0" is defined by com.infairy.cocina.SDK.device.DevicePool#DEVICE_OPERATION_xxx
then defined the Operation object( refer to Operation):

        public class myFirstBundle implements BundleActivator, Runnable{
            ...
           
           /*
            * Bundle ID
            */
           String BundleID="";
           
           /*
            * Layout ID
            */
           String LayoutID="";
           
           Thread me;

           /*
            * Layout object 
            */
           Layout layout;
           
          /*
           * entry point
           */
          public void start(BundleContext context) throws Exception {
              ...
              /*
               * get layout service
               */
              layout=(Layout)Tools.getService(context, Layout.class.getName(), "(FUNCTION=LAYOUT)");

              .....

              /*
               * define operation for layout key mapping
               */
              Vector Operation=new Vector();
              OperationDNA oobj=new OperationDNA();
              
              //when user click the image layout object, this operation object will trigger to run the Funtoin:Go()
              oobj.KEY=device.DEVICE_OPERATION_USER_DEFINED_0;   
              oobj.Function="Go";
              Operation.addElement(oobj);
              
              dict.put(InfairyInterface.DeviceOperation, Operation);

              ...
              
              BundleID=device.addDevice(this, dict);
            

You have also implemnt Go() function to catch up the action.

              public void Go(){
                ....
              }
            

The Camera layout object properties show as below:

          /**
           * Layout id of bundle
           */
          public String LayoutID="";
          /**
           * layout width in pixel, default is 10
           */
          public int width=10;
          /**
           * layout height in pixel, default is 10
           */
          public int height=10;
          /**
           * layout axis of left, default is 0
           */
          public int left=0;
          /**
           * layout axis of top, default is 0
           */
          public int top=0;
          /**
           * Camera id, {@link /cgi-bin/Get.cgi?CAMERA}
           */
          public String CameraID="";
          
          /**
           * Background color
           */
          public String backgroundColor="";
          /**
           * layout visibility
           */
          public boolean visible=true;
          
          /**
           * Other(except Mjpeg) codec url
           */
          public String Codec="";
