With:

var app = angular.module('pdfViewerApp', [ 'ngPDFViewer' ]);

app.controller('PdfController', [ '$scope', 'PDFViewerService', function($scope, pdf) {
    console.log('PdfController: new instance');

    $scope.instance = pdf.Instance("viewer");

    $scope.nextPage = function() {
        $scope.instance.nextPage();
    };

    $scope.prevPage = function() {
        $scope.instance.prevPage();
    };

    $scope.gotoPage = function(page) {
        $scope.instance.gotoPage(page);
    };

    $scope.pageLoaded = function(curPage, totalPages) {
        $scope.currentPage = curPage;
        $scope.totalPages = totalPages;
    };

    $scope.loadProgress = function(loaded, total, state) {
        console.log('loaded =', loaded, 'total =', total, 'state =', state);
    };
}]);
