Html5- what you need to know and why you should care
- 2. BACKGROUND
- 11. Publish to iPhone from Captivate 5 To deploy a Captivate course on an iPhone you need Adobe eLearning Suite 2, or both Adobe Captivate 5 and Adobe Flash Professional. You also need to install the ‘Packager for iPhone’ from Adobe Labs. 1. Get an iPhone developer certificate from Apple 2. Get Development Provisioning profile from Apple (A file that lets you test or distribute an iPhone application. You obtain provisioning profile files from Apple. A provisioning profile is assigned to a specific development certificate, an application ID, and one or more device IDs). More details here. 3. Create a Captivate project for the iPhone form factor – 320 *480 4. While publishing the SWF, turn ON this option in the publish dialog – “Enable SWF for conversion to iPhone application”.
- 13. Low Bandwidth Player • Automatically adds HTML feature when/if you add PNGs of slides • Automatically adds embedded audio if you include files • Automatically switches to HTML if no flash is detected (and pngs are present) • Notifies LMS when course is complete • Slide Index toggles with Articulate outline panel setting • Uses HTML5 and degrades nicely for IE http://www.frameentered.com/content/low‐bandwidth‐html‐articulate‐ player‐waudio‐reports‐lms‐too
- 16. HTML STUFF
- 17. HTML5 Stack • HTML5 – the markup language • CSS3 (the latest version of Cascading Style Sheets) – how it looks or is rendered • JavaScript – the programming language
- 19. Browser Support
- 22. Document Object Model (DOM) • Check if a certain property exists on a global object (such as window or navigator) – Example: testing for geolocation support • Create an element, then check if a certain property exists on that element – Example: testing for canvas support • Create an element, check if a certain method exists on that element, then call the method and check the value it returns – Example: testing which video formats are supported • Create an element, set a property to a certain value, then check if the property has retained its value (think about forms) – Example: testing which <input> types are supported HTML5 – Up and Running: Mark Pilgrim
- 23. Features • New structural and semantic markup – Such as header, footer and nav elements • The new canvas element – Creating web based bitmap graphics using JavaScript • New native audio and video elements, and related elements and attributes – Embedding multimedia content that browsers can play without plugins
- 24. NAV Element <nav> <ul> <li><a href="/">Home</a></li> <li><a href="/products">Products</a></li> <li><a href="/services">Services</a></li> <li><a href="/about">About</a></li> </ul> </nav> The nav element represents a section of a page that links to other pages or to parts within the page: a section with navigation links. Not all groups of links on a page need to be in a nav element only sections that consist of major navigation blocks are appropriate for the nav element.
- 25. Tags • <audio> tag defines sound content • <canvas> tag defines graphics • <footer> tag defines a footer for a section or page • <header> tag defines a header for a section or page • <nav> tag defines navigation links • <time> tag defines a date/time • <video> tag defines a video
- 31. Geolocation API • Allows a web site or application to ask the browser where a user is located (including longitude, latitude and altitude, but also potentially the direction they are facing, and their speed) • Of course, whether the user wishes to share this information is at their discretion) function get_location() { navigator.geolocation.getCurrentPosition(show_map);}
- 33. HANDS‐ON
- 42. Draw with Javascript Draw a red rectangle. The fillStyle method makes it red. The fillRect method specifies the shape, position, and size. <script type="text/javascript"> Var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.fillStyle="#FF0000"; cxt.fillRect(0,0,150,75); </script>
- 43. Draw with Javascript The fillRect method above had the parameters (0,0,150,75). This means: Draw a 150x75 rectangle on the canvas, starting at the top left corner (0,0). The canvas' X and Y coordinates are used to position drawings on the canvas. <script type="text/javascript"> Var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.fillStyle="#FF0000"; cxt.fillRect(0,0,150,75); </script>
- 45. Canvas vs. SVG • Think of the difference between canvas and svg as the difference betwee Photoshop and Illustrator (One deals with bitmaps and the other vector art. • With canvas, since you are drawing in bitmap, you can smudge, blur, burn, dodge your images easily. But since it's bitmap you can't easily draw a line and then decide to reposition the line. You need to delete the old line and then draw a new line. • With svg, since you are drawing vectors, you can easily move, scale, rotate, reposition, flip your drawings. But since it's vectors you can't easily blur the edges according to line thickness or seamlessly meld a red circle into a blue square. You need to simulate blurring by drawing intermediate polygons between objects.
- 46. SVG • SVG stands for Scalable Vector Graphics • SVG is used to define vector‐based graphics for the Web • SVG defines the graphics in XML format • SVG graphics do NOT lose any quality if they are zoomed or resized • Every element and every attribute in SVG files can be animated
- 47. SVG Advantages • SVG files can be read and modified by a large range of tools (e.g. notepad) • SVG files are smaller and more compressible than JPEG and GIF images • SVG images are scalable • SVG images can be printed with high quality at any resolution • SVG images are zoomable (and the image can be zoomed without degradation) • Text in SVG is selectable and searchable (excellent for making maps) • SVG works with Java technology • SVG is an open standard • SVG files are pure XML
- 50. File vs. Video Formats • One of the biggest sources of confusion about video is not realizing that the file format is completely different from the video format. So you're always dealing with two formats, not one. • Examples of file formats are .mp4, .flv, f4v, .ogv, or .avi. File formats are often called container formats because they're containers for the actual video. • The video format is the flavor of compression that's used on the video. This is often called a codec.
- 52. Flash A movie.FLV (Flash) file could also hold H.264 video, or it could hold video encoded with vp6 or Sorenson Spark. But it can't hold MPEG‐4 video.
- 53. OGV A movie.OGV file is primarily for Theora and other even more obscure formats. It can't hold MPEG‐4 or H.264, at least not easily. To convert videos to the .ogg/.ogv format, install the Firefogg extension into your Firefox browser.
- 56. Three Parts to Video • The file format that holds the video, like .mp4, .flv, .f4v, .ogv, or .avi • The video format (aka codec), like H.264, MPEG‐4, or Theora • The player that makes it available to your site visitors, such as the Adobe Flash Plugin, or the new <video></video> tag.
