how to get a document from SVGGraphics2D?
hi there,
there is something basic i didn't get on SVGGraphics2D:
i would like to create an svg and show it in a JSVGCanvas. this must
be easy but it just doesn't work :-(
looking at the first example on
http://xml.apache.org/batik/svggen.html, i don't understand what the
Document document is good for. the streaming is done directly from the
SVGGraphics2D svgGenerator
if i look at the document, it remained an empty svg-document.
if i use the trick i found in the mailing list:
document.removeChild(document.getDocumentElement());
document.appendChild(treeManager.getRoot());
i can get some elements in the documents, but it doesn't show when i
put the document into the JSVGCanvas by canvas
canvas.setSVGDocument(document);
and moreover, manipulating the document in this way has the side
effect of emptying the SVGGraphics2D svgGenerator: all graphic parts i
just drew in the svgGenerator are cut away when streaming out the
svgGenerator.
it can't be that i have to stream out and into a new svg document, can
it?
if someone could just give me the probably 3 lines of code of making
an SVGDocument and showing it in the canvas, i'd be really very
grateful!
thanks in advance
kim

Gerdes,
I have attached a sample that does what you are asking for. As you
guessed, you do not have to stream out the document before viewing
it: it can be done directly.
Cheers,
Vincent.
