3D FlipBook - Default zoom

Hi,

Recently i've purchased 3D FlipBook jquery plugin.

I'd like to know how can i set zoom default before open my pdf's.

I know that there's a property, but i can't do that works.

¿Could you please send me an example?

This is my code

if(target[0]) { instance.options = { pdf: rutasLibros[target.attr('data-book-id')], propertiesCallback: function(props) { props.page.depth /= 3; return props; }, template: { html: 'GENERATE_PDF/templates/default-book-view.html', styles: [ 'GENERATE_PDF/css/black-book-view.css' ], links: [{ rel: 'stylesheet', href: 'GENERATE_PDF/css/font-awesome.min.css' }], script: 'GENERATE_PDF/js/default-book-view.js', sounds: { startFlip: 'sounds/start-flip.mp3', endFlip: 'GENERATE_PDF/sounds/end-flip.mp3' } }, styleClb: styleClb };

        $('.fb3d-modal').fb3dModal('show');
      }

thank you

Miguel
