Hello,
I want
1. To manipulate a svg-document and then export it to svg file
2. Then manipulate existing svg-document again and export it second
time to a svg file and so on...
I noticed that after a svg-document was exported to an svg file with
|svgGenerator.stream(streamWriter, useCss)| method the svg document
become empty.
Can some body give me a hint, what is wrong in my code?
I posted my question on stack-overflow, but didn't get any answer, so
you are my last hope :-)
|public void svgExportExample() {
finalSVGGraphics2D svgGenerator= createSvgGenerator();
drawRectangle(svgGenerator);
drawText(svgGenerator);
finalString xml1= toXml(svgGenerator);
finalString xml2= toXml(svgGenerator);
assertEquals("xml document was not changed and should be the same",
xml1, xml2);
}
private SVGGraphics2D createSvgGenerator() {
finalDocument document= initNewDocument();
finalSVGGraphics2D svgGenerator= new SVGGraphics2D(document);
return svgGenerator;
}
private Document initNewDocument() {
// Get a DOMImplementation.
finalDOMImplementation domImpl= GenericDOMImplementation
.getDOMImplementation();
// Create an instance of org.w3c.dom.Document.
finalString svgNS= "http://www.w3.org/2000/svg";;
return domImpl.createDocument(svgNS, "svg", null);
}
private String toXml(finalSVGGraphics2D svgGenerator) {
try (ByteArrayOutputStream os= new ByteArrayOutputStream();
OutputStreamWriter streamWriter= new OutputStreamWriter(os)) {
final boolean useCss= true;
// this method clears the content of the xnl-document
svgGenerator.stream(streamWriter, useCss);
return os.toString(StandardCharsets.UTF_8.name());
} catch (finalIOException e) {
throw new IllegalStateException(
"a proble during printing to svg file was occured", e);
}
}
private void drawText(finalGraphics2D g) {
finalString text= "My Text inside Svg";
finalint fontSize= 10;
finalint width= 10;
finalint height= 10;
finalGraphics g1= new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB).getGraphics();
finalint style= 0;
finalFont font= new Font(g1.getFont().toString(), style, fontSize);
g1.dispose();
g.setFont(font);
g.setColor(Color.GREEN);
g.drawString(text, 50, 100);
}
private void drawRectangle(finalGraphics2D g) {
g.setColor(Color.RED);
finalint width= 500;
finalint height= 300;
g.fillRect(0, 0, width, height);
}|
