The designer interface can be shown in different languages, and several localization files can be offered at once.

Designer setup. Configure the designer, load the report template, process its callbacks, and connect the save action to the application.
$designer = new StiDesigner();
$designer->options->localization = 'de.xml';
$designer->options->addLocalization('fr.xml');
$designer->options->addLocalization('es.xml');
$designer->options->addLocalization('pt.xml');
$designer->process();


options->localization sets the active language and addLocalization registers additional ones the user can switch to. Localization files ship with the product and can be edited or created.
