Render Graphics with SVG
With SVG, you can represent graphics as XML documents and render them in Internet Explorer with Adobe’s SVG Viewer, in Netscape with Corel’s SVG Viewer, in a branch of Mozilla that supports SVG, and in Batik’s Squiggle.
Scalable Vector Graphics or SVG (http://www.w3.org/Graphics/SVG/) is an XML vocabulary for describing two-dimensional graphics. Using XML instead of one of a variety of proprietary graphical formats, SVG has enormous potential as a method for storing and transporting graphics. It was developed by the W3C and is currently at Version 1.1 (http://www.w3.org/TR/SVG11/).
SVG is popular and the number of implementations is steadily increasing. Adobe provides a popular browser plug-in, SVG Viewer 3.0, which runs on Windows and the Mac. (There is a rumor floating about that it will soon run on Linux.) Mozilla.org has a version of its browser, a branch off the main trunk of code, that supports SVG rendering natively (i.e., without a plug-in). Apache’s Batik project offers an SVG browser written in Java.
Following is a simple example of an SVG document that renders some colored text, text.svg (Example 4-13):
Example 4-13. text.svg
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" width="600px" height="300px" font-size="150px"> <rect fill="none" stroke="black" stroke-width="3" x="170" y="65" width="235px" height="125px"/> <text ...
