  • 11. DemoCSS3Medium query
  • 12. Canvas basics Dynamic bitmap with JS Allow drawing into a bitmap area  See it as a dynamic PNG ;-) JavaScript APIs & drawing primitives  Rectangles, lines, fills, arcs, Bezier curves, etc. Immediate mode : « Fire and Forget »  It does not remember what you drew last.  It’s up to you to maintain your objects tree This is a black box : content not visible into the DOM  Beware of accessibility issues Simple API: 45 methods, 21 attributes
  • 13. Canvas Entire API
  • 14. DemoCanvas BasicsThe element, interactivity
  • 15. SVG basicsScalable Vector Graphics Scalable Vector Graphic  To draw 2D vector graphics using XML  “retained mode” : the objects tree is kept in memory Full DOM support  Access to the SVG elements through the DOM SVG elements can be styled with CSS & can be decorated with ARIA Included in HTML5 spec  Native support in IE9 and other modern browsers Can be used from an external .svg file or in-line in the document
  • 16. DemoSVG BasicsThe element, some styling & interactivity
  • 17. Scenarios: Canvas and SVG
  • 18. Combination/Crossover ScenariosMore subtle differences Charts and Graphs  SVG better for interaction, XML data loading & for printing  Canvas could be a faster rendering choice for some browsers Two-Dimensional Games  Canvas offers a more familiar experience to game developers (low level APIs, immediate mode as XNA, etc.)  SVG does a lot of DOM operations and cost more memory
