paint in vector graphics

Hi,

I want to make a vector graphics with Java.
I already make an GUI with some JPanel there and I have write a paint method for the Graphics using Graphics2D.
But since the Quality of the Graphics is not as expected, we want to change the paint method through vector graphics.
Since I´m still a newbie in Java, I´ve googled for this vector graphics possibilities with Java, and Batik is as far as I can find.
But as far as I concerned, with Batik I cannot draw on the JPanel, which I already have.

So.... Are there any other possibilities to draw vector graphics other than Batic?
Or have anyone use batik and can give me some example to paint with it on a JPanel?

thanks for any help.

But AFAIK, Batik can draw on a JSVGCanvas object which derives from JComponent, so this should be easily usable form within a Swing application.

The Batik api can be found here: Apache Batik Javadoc

So... I wanna try it, but when I read the data (since I need to read the xml-data first for the input), I got error message:

<code>
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/apache/batik/svggen/SVGGraphics2D
<code>

But when I´m not using any batik api, the program run smoothly.

Does anyone know, what that error message mean? And how to fix it?
Thank you in advance.

Do you have the Batik jar file(s) in your class path, or if you're using an IDE, are they in the project's compile path?

yo... I´ve already downloaded the Batik jar files and compile it in the project library

I post the error code, which I get when I run the program.

The program running smoothly without BATIK. But when I insert BATIK for SVG Graphics, I got the error code like these.
What I cannot understand, I got the error when it still on the step of reading the XML-Data (since I need to read the Datas for the Graphics) and it hasn´t ever gone to class and method for the drawing graphics.

I try to re-download the BATIK and reinstall and recompile the BATIK files jar to the project, but it still got the same error.

Has anyone any idea?
Thank you very much.

well... the problem before is solved... but now I have another problem.

so.. the code I write on JSVGCanvas is:

Code:

---

DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
Document doc = impl.createDocument(svgNS, "svg", null);
SVGGraphics2D svgGraphics = new SVGGraphics2D(doc);
EvaluateDrawing drawing = new EvaluateDrawing(dataModel.getGDSDataModel());
Element root = doc.getDocumentElement();
svgGraphics.getRoot(root);
canvas1.setSVGDocument(doc);

---

but when I compile it, I got the error code like this:

Code:

---

setSVGDocument(org.w3c.dom.svg.SVGDocument) in org.apache.batik.swing.svg.AbstractJSVGComponent cannot be applied to (org.w3c.dom.Document)
                canvas1.setSVGDocument(doc);

---

Can anyone help me, what should I do?

Thank you very much

Hallo,

since I still don´t know the answer of the problem before, I try to make it another way to paint in vector graphics.
I can now make the vector graphics in svg and I save the svg file first.
After that, I read the file again on my JSVGCanvas (canvas1), which is on the panel, to show the graphic.

Since I use Netbeans for the IDE, I must override the paint-methode to show the graphic.

Here is the code.

Code:

---

panel =  new JPanel (){
    public void paint(Graphics g) {
            super.paint(g);
            panel.setOpaque(true);
            panel.add(canvas1);
            canvas1.setURI(new File("ProfilRight.svg").toURI().toString());
            canvas1.repaint();
        }
    }

---

But when I compile the program, I get an endlose run of this paint method, so that the graphic won´t be displayed.

Can anyone help me, how I can correct the code?

Thank you very much in advance for any help...
