Key SVG Scenarios

• SVG Scenarios• Engineering Documents

• Used in a lot of our enterprise customer shops• Recommended -> required by Governmental Institutions

• Graphs / Charts / Maps • Removes load from server to produce high fidelity graphics• Supports end user interactivity and Ajax style data updates

• Currently used on Google and Bing• Media and Graphics

• CSS or background images• Posters (great for printing)• JavaScript-animated Graphics

Getting Started: Embedding

Methods by which SVG can be embedded in a browser

IE9 Developer Preview Support• The SVG in HTML5 embedding method without using foreign

object (i.e. just create an <svg> tag in your HTML file)• SVG as a full document type (with .SVG extension)• SVG in XHTML (similar to that of HTML, only with XHTML

files)• SVG using <object>

Support in IE9• <iFrame>, <embed>• As <img> or css-image• .SVGZ

<object data="rect2.svg" width="100%“ height="400px" type="image/svg+xml" >

Getting Started: Structure

Tag Usage

<svg> (no <viewbox> support) Primary wrapper for SVG content. Support for nested SVG.

<defs> <use> Clones, “re-uses” SVG Content

<g> Method for grouping SVG

<image> Same as <img> in HTML

Getting Started: Presentation

Tag Usage

<circle>, <ellipse>, <rect>, <line>, <polyline>, <polygon>

Elements for drawing basic shapes

<path> Geometry of the an object, defined in terms of moveto (set a new current point), lineto (draw a straight line), curveto (draw a curve using a cubic Bézier), arc (elliptical or circular arc) and closepath

<text> (no <tspan> support) Basic Text in SVG (no wrapping)

Filling, stroking, color Methods for painting, filling and outlining basic shapes and paths

Getting Started: Interactivity/Styling

Tag Usage

DOML2 Core and SVGDOM If the element exists, most likely the corresponding SVGDOM support exists. This means that scripting of SVG is readily available.

Events Most events are in place; some SVG specific events are coming next

Presentation Attributes / CSS Using CSS and presentation attributes on elements

Getting Started: Transforms

Tag Usage

translate Shift the SVG content (x,y)<transform="translate(-10,-20)">

skewX/skewY Skew the content horizontally or vertically<transform="skewX(30)”>

scale Scale the content<transform="scale(2)">

rotate Rotate the content<transform="rotate(45)">

What’s coming in Internet Explorer Platform Preview

• What’s Coming Next • Gradients• Clipping / Masking / Compositing• Linking and Views• Remainder of Text, Transformations, Color,

Interactivity/Events

Call to Action!

• Let’s Get Going!

• Download the Internet Explorer 9 Platform preview

vwww.IETestDrive.com• Visit W3Schools (for initial learning)• Build your own SVG and share with the community

• Join my Facebook group (SVG in Internet Explorer)• Make modifications to Open Source Frameworks to Allow

for SVG (instead of VML)• Help us make sure we are interoperable by reporting any

divergences
