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:

{ 
"en":{ 
"CloseButton.TOOLTIP":"Close", 
"ZoomInButton.TOOLTIP":"Zoom In" 
 }, 
 "fr":{ 
"CloseButton.TOOLTIP":"Fermer", 
"ZoomInButton.TOOLTIP":"Agrandir" 
}, 
defaultLocale:"en" 
}

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.
