"SVGMorpheus is not defined" in angular directive

[deejbee]

I have added the library to the page but when i do something like this:

 .directive('myDirective', function () {
            return {
                template: '<content-tag></content-tag>',
                link: function (scope, element, attr) {
                        var myIcons = new SVGMorpheus('#pinkFrames', { iconId: 'pinkFrame1'});
                        myIcons.to('#pinkFrame2', {}, null);
                   }
                }
            }
        });

I get:

SVGMorpheus is not defined ReferenceError: SVGMorpheus is not defined
