Using pan and zoom displays
Pan and zoom
displays allow you to author a single large display covering all, or a large
portion, of your process in a single display. An example of a display that would benefit from
this functionality is a map of a long pipeline with equipment at various locations.
You open a pan and zoom display the same way as you open any display. You will be able to
recognize a pan and zoom display from the presence of the “thumbnail”. The
thumbnail
provides a representation of the entire display as well as an indication of the current
“viewport”. The
viewport
indicates which portion of the overall display you are currently
viewing.
