Hello again:
I am loading an existing SVG file into a Document and adding some nodes
to it.
When I take the resulting Document and transcode it to JPEG or PNG, the
additions (a new <path>) I made do not show up in the image. I printed
the dom to inspect it and my additions were present and formatted
correctly.
//Load dom
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
String uri = new File(getServletContext().getRealPath("/") +
"svg\\polarity.svg").toURL().toString();
SVGDocument doc = (SVGDocument) f.createDocument(uri);
. . .
//perform addition of new <path> . . .
. . .
DOMUtil.printDOM(doc); //Print dom to console - everything is
fine
response.setContentType("image/png");
ServletOutputStream out = response.getOutputStream();
PNGTranscoder t = new PNGTranscoder();
t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY, new Float(.8));
t.addTranscodingHint(JPEGTranscoder.KEY_HEIGHT, new
Float(1000));
t.addTranscodingHint(JPEGTranscoder.KEY_WIDTH, new Float(1000));
TranscoderInput input = new TranscoderInput(doc);
TranscoderOutput output = new TranscoderOutput(out);
try {
t.transcode(input, output);
}
catch (TranscoderException e) {
e.printStackTrace();
}
out.flush();
out.close();
The added node prints as:
<path
style="fill:none;fill-rule:evenodd;stroke:#000000;stroke-width:10px;stro
ke-linecap:butt;strike-linejoin:miter;stroke-opacity:1" d="M -120,-300 C
-200,-300 -200,0 -200,0" id="curveA">
08/03/06 11:54:18 </path>
Other paths have the < and are not affected. Any suggestions?
Regards,
Eric Hamacher
