Class SVGUtil

java.lang.Object

org.abego.treelayout.demo.svg.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();
    }
}
