ViewONE JavaScript Overview
The ViewONE Javascript API offers an alternative mechanism to configure and control the
ViewONE applet.
In many cases the use of the Javascript API will not be required simply because most
configuration parameters can be implemented using simple HTML (see ViewONE HTML
manual).
However, where a more dynamic operation is required, for example, where it is desired to
configuration parameters during the operation of ViewONE, perhaps to change a
document without reloading a web page, rotate a page, invert etc then the JavaScript API
is ideal.
Additionally, traditional web viewing applications habitually reload a web page in order to
view or change the currently viewed image/document.
But with ViewONE’s extensive Image/Document open/close JavaScript API methods it is
possible to avoid web page refreshing entirely. This can result in significant performance
improvements since all delays due to web page rehfreshing (and therefore Java Engine
reloading and applet restarting) are avoided.
Daeja has produced white paper specifically addressing performance tuning which covers
the area of web page refreshing and applet reloading. Please visit Daeja’s web site to
