How can I achieve Whole PTZ capabilities as shown in the below Image in my own _imageViewerControl which is been used in my plugin
Unfortunately these PTZ actions are not open for MIP plug-ins. What is open you can see in the PTZandPresets sample.
It might come late in your development but I got an idea. If you instead of developing your own view item develop a background plug-in that will monitor cameras and if a camera fails then it will update the view (using the regular built-in camera view item) with a SetCameraInView command. The benefit is using the built-in camera view item with all the functionality it automatically has.
