NPSVideo Control Reference

NPSVideo Control

The Surround Video Netscape Plug-in provides content providers with the ability to view 360 degree panoramic images.  These images can be stored either on a local drive, or on a web server.  The control will download the data from the specified URL, using Netscape's asynchronous file download mechanism

A Surround Video Image consists of a number of vertical stripes that make up the complete image.  The benefit of striping the image is that any stripe can be loaded independently, so only the visible portion of the image needs to be furnished in order for rendering to occur.  Each image can have areas on them defined as Links( HyperLinks ).  These links can be defined as either “Internal” or “External”.  When a link is selected from within the control, the control first determines whether the link is defined as internal or external, then takes the appropriate action.  If the link is defined as internal, the control attempts to open the specified data source name for that link within itself.  If the link is defined as external, the control notifies its container that it needs to handle the opening of the specified data source name for that link.
