- 13. 13 Scalable VectorGraphics with W3C recommended Used to describe 2D-graphics using XML XML rendered by an SVG viewer. Mainly used for Pie charts, Two-dimensional graphs in an X,Y coordinate system etc. Do not loose any quality on zoomed or resized Every element and every attribute can be animated

- 18. 18 Web Storageas a standardised and native API Easily retrievable javascript objects 2 ways to store data on the client side a) Web SQL database b) Web Storage - key/value pair storage system i) local storage ii) session storage
- 19. 19 Session Storagevs Local Storage Session Storage Local Storage Values persist only as long as the window or tab in which they were stored. Values are only visible within the window or tab that created them. Values persist beyond window and browser lifetime. Values are shared across every window or tab running at the same origin.

- 21. Database API Storecomplex relational data and perform simple or complex queries on those data Brings SQL to the client side It has 3 main methods 21 1) openDatabase: It creates the database object either using existing database or creating new one. 2) transaction: It gives us the ability to control a transaction and performing either commit or rollback based on the situation. 3) executeSql: This method is used to execute actual SQL query.

- 25. 25 Overview ofGraphics in Browsers Static images : <img> tag Dynamic graphics? No native support Current solution - - use plug-ins such as Flash, Silverlight etc. - HTML5 <canvas> element
- 26. 26 Canvas vsSVG Canvas SVG Advantages −> High performance graphics −> Pixel−level manipulation −> Constant performance depending on the resolution used −> Canvas drawing surface can be saved as an image file -> Vector-based, scalable to any resolution -> Good support for animations -> DOM manipulated elements Drawbacks -> No API for animation, you have to redraw every time -> Pixel manipulation - impossible for shape you create to respond to events -> Not scalable -> Not suited for user interfaces -> Works with the DOM, so with a lot of elements, it gets slower -> Not suited for gaming application

- 28. 28 Current scenario Based on plug-ins i.e. Silverlight, Flash Browser uses the <object> tag and can’t differentiate w.r.t. audio/video An end user might not have the plug-in installed/ not permitted Plug-ins are not cross-platform Flash - not supported on iOS
- 29. 29 With HTML5 Use of<audio> and <video> tags Need to set src attribute to identify the media source Include a controls attribute It supports - Audio Video Interleave (.avi) - Flash Video (.flv) - MPEG 4 (.mp4) - Matroska (.mkv) - Ogg (.ogv)

- 31. 31 Geographic andLocation Share user’s location, find direction etc. There are many ways to share the location - GPS - Location inferred from network, IP address, wifi - Cell IDs - User Input Sharing user location -> a privacy concern!!! User must give explicit permission to the user agent Some privacy concern will still present - How long the data will be stored - Is it shared with other sites - Can the location data be updated/deleted by end user?
