Localization of user interface elements

Certain content that the Video Viewer displays is subject to localization, including zoom buttons and a full screen button.

Every textual content in the viewer that can be localized is represented by a special Viewer SDK identifier called SYMBOL. Any SYMBOL has a default associated text value for the English locale ( "en") supplied with the out-of-the-box viewer. It also may have user-defined values set for as many locales as needed.

When the viewer starts, it checks the current locale to see if there is a user-defined value for each supported SYMBOL for the locale. If there is, it uses the user-defined value; otherwise, it falls back to the out-of-the-box default text.

User-defined localization data can be passed to the viewer as a localization JSON object. Such object contains the list of supported locales, SYMBOL text values for each locale, and the default locale.

An example of such a localization object is the following:

"ZoomInButton.TOOLTIP":"Zoom In" 

In the above example, the localization object defines two locales ( "en" and "fr") and provides localization for two user interface elements in each locale.

The web page code should pass such localization object to the viewer constructor as a value of localizedTexts field of the configuration object. An alternative option is to pass the localization object by calling the setLocalizedTexts(localizationInfo) method.

The following SYMBOLs are supported:


Tooltip for the...


ARIA label for top level viewer element.


ARIA role description for main view component.


ARIA usage hints for keyboard users.


Close button.


Zoom in button.


Zoom out button.


Zoom reset button.


Full screen button in normal state.
