Using Batik to manipulate SVG

Batik Introduction

Batik is a Java toolkit for applications that want to use SVG to implement a variety of functions. With batik, you can manipulate SVG documents anywhere you use Java, or you can use the Batik module to generate, manipulate, and convert SVG images in applications or applets.

With batik, it's easy to manipulate SVG content, allowing Java applications to have a simple output image formatted as SVG using the Batik svggernerate module, with batik svg viewing Component enables Java applications to integrate SVG viewing and interactivity capabilities, as well as to convert SVG formats to other formats, such as JPEG and PDF, using Batik's modules.

Batik Use

Use instance one: Generate SVG documents with batik

Package test;
Import Java.awt.Color;
Import Java.awt.Graphics2D;
Import Java.awt.Rectangle;
Import Java.io.OutputStream;
Import Java.io.OutputStreamWriter;
Import java.io.UnsupportedEncodingException;
 
Import Java.io.Writer;
Import org.apache.batik.dom.GenericDOMImplementation;
Import Org.apache.batik.svggen.SVGGraphics2D;
Import org.apache.batik.svggen.SVGGraphics2DIOException;
Import org.w3c.dom.DOMImplementation;
 
 
Import org.w3c.dom.Document; public class Testsvggener {public void paint (graphics2d g2d) {g2d.setpaint (color.red);//Draw a rectangle G2d.fill (new Rectangle (1
0,10,100,100));
} public static void Main (string[] args) throws Unsupportedencodingexception, Svggraphics2dioexception {
Domimplementation domimpl=genericdomimplementation.getdomimplementation ();
String svguri= "Http://www.w3.org/2000/svg";
Create SVG file document Doc=domimpl.createdocument (Svguri, "SVG", null);
Svggraphics2d svggener=new svggraphics2d (DOC);
Testsvggener test=new Testsvggener ();
Test.paint (Svggener); Boolean uSecss=true;
Output SVG file Writer out =new outputstreamwriter (System.out, "UTF-8");
Svggener.stream (OUT,USECSS);
  }
}

Results:

Use example two: Convert SVG documents to PDF and PNG using batik
