Interoperability of digilib HTML pages with the Alcatraz toolbar

+ +

A toolbar-friendly digilib page must define a Javascript variable +toolbarEnabledURL whose value is a HTTP URL that +produces a toolbar-enabled page. The toolbar should present a +button to "take over" the page design by replacing +the current page with the page from the given URL.

+ +

Toolbar-enabled page

+ +

A toolbar-enabled page must offer the following Javascript functions:

+ +

Identification

+ +

dlScriptVersion: a String variable that contains the version number of the Javascript code (e.g. "1.12b3")
+ The existence of this variable can be used to test for a toolbar-enabled page

+ +

Interactive operations

+ +

setMark(): lets the user click and sets a mark at the clicked location
zoomArea(): lets the user click to select an area and zooms to the selected area
moveCenter(): lets the user click and recenters the image around the clicked location

+ +

+ +

getRef(): returns a String with a URL reference to the current document
removeMark(): removes the last mark
zoomBy(float factor): magnifies the image by the given factor around the current center
zoomFullpage(): zooms out so that the whole image is visible

+ +

getParameter(String name): returns the value of the parameter with the name name
setParameter(String name, String value): sets the value of the named parameter (value can be of any type)
