calculate bounding box coordinates

calculate bounding box coordinates

var BOTTOM_PADDING = 25; 
    
// calculate the bounding box for the image
var containerNode = Y.one('#containerId');
        
// viewport height
var windowHeight = Y.one('body').get('winHeight');
        
// grab the box's width based on it's container
var boxWidth = parseInt(mediaPlayerNode.get('offsetWidth')) - 15; // 15px??
        
// bounding box height, width
var boxHeight = windowHeight - containerNode.getY() - BOTTOM_PADDING;
        
// bounding box coordinates
var topLeft = containerNode.getXY();
var topRight = [topLeft[0] + boxWidth, topLeft[1]];
var bottomLeft = [topLeft[0], topRight[1] + boxHeight];
var bottomRight = [topRight[0], topRight[1] + boxHeight];
