AW: Problems saving and showing a SVGDocument

[Lolling, Jan]

The problem is the simple methode stream. This methode do not format anything and no line delimiter will be added. Write your saving methode with using the transcoder class.

 

SVGTranscoder transcoder = new SVGTranscoder();

// transcoder.addTranscodingHint(SVGTranscoder.KEY_NEWLINE,SVGTranscoder.VALUE_NEWLINE_LF);

transcoder.addTranscodingHint(SVGTranscoder.KEY_DOCTYPE, SVGTranscoder.VALUE_DOCTYPE_CHANGE);

//transcoder.addTranscodingHint(SVGTranscoder.KEY_FORMAT, SVGTranscoder.VALUE_FORMAT_OFF);

OutputStream outputStream = null;

TranscoderInput input = new TranscoderInput(getSVGDocument());

try {

outputStream = new FileOutputStream(filename);

} catch (FileNotFoundException fnfe) {

fnfe.printStackTrace();

}

if (outputStream != null) {

TranscoderOutput output = new TranscoderOutput(new OutputStreamWriter(outputStream));

try {

transcoder.transcode(input, output);

} catch (TranscoderException e) {

e.printStackTrace();

}

try {

outputStream.flush();

outputStream.close();

isDocumentChanged = false;

} catch (IOException e) {

e.printStackTrace();

}

}

Betreff: Problems saving and showing a SVGDocument

I am experimenting problems when trying to save and then show an SVGDocument. The code I am using is included below. If I do not save it, then the graphic is shown and if I save it (as in the included code) the graphic is not shown (a white frame appears).

Any suggestions?

Thanks, Marcelo.

// Create SVG doc
String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
SVGDocument doc = (SVGDocument) impl.createDocument(svgNS, "svg", null);
SVGGraphics2D g = new SVGGraphics2D(doc);

 

// draw something
g.setPaint(Color.YELLOW);
g.fill(new Ellipse2D.Double(10, 10, 100, 20));

 

// Save
OutputStream file = new FileOutputStream(afileName);
Writer out = new OutputStreamWriter(file, "UTF-8");
svgGenerator.stream(out, false);
file.close();

 

// show
g.getRoot(doc.getDocumentElement());
JSVGCanvas canvas = new JSVGCanvas();
JFrame f = new JFrame();
f.getContentPane().add(canvas);
canvas.setDocument(doc);
f.pack();
f.setVisible(true);
