Class SVGUtil

de.hsh.graja.regression.report.treevisualiser.SVGUtil

public class SVGUtil
extends Object

A set of methods to generate SVG content.

Mainly to keep the footprint small only a very limited set of SVG functionality is supported. In case more features are required have a look at Batik - Java SVG Toolkit.

Example

 String s = doc(svg(
         160,
         200,
         rect(0, 0, 160, 200, "fill:red;")
         + svg(10, 10, 100, 100,
                 rect(0, 0, 100, 100, "fill:orange; stroke:rgb(0,0,0);"))
         + line(20, 20, 100, 100, "stroke:black; stroke-width:2px;")
         + line(20, 100, 100, 20, "stroke:black; stroke-width:2px;")
         + text(10, 140,
                 "font-family:verdana; font-size:20px; font-weight:bold;",
                 "Hello world")));
 
 File file = new File("demo.svg");
 FileWriter w = null;
 try {
     w = new FileWriter(file);
     w.write(s);
 } finally {
     if (w != null) {
         w.close();
     }
 }
