Example

This is how Elementi 2015 uses the jSignage Multiscreen add-on to create a multiscreen array project, based on a user-editable configuration.

var config = $.parseJSON( $( '#config' ).text() );
var setup = $.Multiscreen.setupArray( config );
$('svg').attr( 'viewBox', setup.viewBox.join(' ') );
$(function(){
    var txt = $('#jsonLayers').text();
    $('#layers').add( $.Multiscreen.uncan( setup, $.parseJSON( txt ) ) );
    if ( setup.blending )
        $('svg').add( $.Multiscreen.edgeBlending( setup.blending ) );
});
