Good! This should work fine for you, with the document loader that
I wrote I am (currently) ignoring the URL. That could work for you, or you could
use the URL to pass some information for presenting your generated code, such as
translation or transformation. Just make sure that the URL is well
formed.
Also,
have your DocumentLoader send an inputstream and not a Reader. as
below:
Document
document = documentFactory
.createDocument(uri,
new
FileInputStream("c:\\Frame_00001_0805.svg"));
If you send a Reader, you have to setup the content type
somewhere, I don't know how to do that.
Enjoy,

In fact, I think my problem is quite different
but the idea is here.
As you know, the loadSVGDocument method takes an URL
argument.
But I can't give it an URL because I have generated a
SVGDocment in my program.
I just want to put this SVGDocument in my JSVGCanvas but I
wasn't be able to.
I tried the setSVGDocument and so on... but without
success.
That is why I suggest to redefine a subclass of JSCGCanvas
and overwrite the paint mathod but I am not sure of the results.
I would to use a JSVGCanvas to make easier manipulations in
the future.
Thanks for all.
I
have had a similar problem, in that I have to retrieve the svg data from a
local database (that is non-networked). So anyhow,
I
created my own class DBDocumentLoader that extends
..batik.bridge.DocumentLoader. That retrieves the information from a
database.
Then I extended JSVGCanvas and
overloaded the loadSVGDocuement(..) function Like below.
My change is the "//Next
Line is OBSI Modification" otherwise it is like the original code in the
latest official release.
/**
* Loads a SVG
document from the database, according to the
URL
* <em>Note: Because the loading is
multi-threaded, the current
* SVG document is
not guaranteed to be updated after this method
* returns. The only way to be notified a document has been
loaded
* is to listen to the
<tt>SVGDocumentLoaderEvent</tt>s.</em>
*/
public void loadSVGDocument(String url)
{
stopProcessing();
URL oldURI =
null;
if (svgDocument !=
null)
{
oldURI =
((SVGOMDocument)svgDocument).getURLObject();
}
URL newURI =
null;
try
{
newURI = new URL(oldURI,
url);
} catch
(MalformedURLException e)
{
userAgent.displayError(e);
return;
}
url =
newURI.toString();
fragmentIdentifier = newURI.getRef();
//Next Line
is OBSI Modification
loader
= new
DBDocumentLoader(userAgent);
nextDocumentLoader = new SVGDocumentLoader(url,
loader);
nextDocumentLoader.setPriority(Thread.MIN_PRIORITY);
Iterator it =
svgDocumentLoaderListeners.iterator();
while (it.hasNext())
{
nextDocumentLoader.addSVGDocumentLoaderListener
((SVGDocumentLoaderListener)it.next());
}
if (documentLoader ==
null
&&
gvtTreeBuilder == null
&&
gvtTreeRenderer == null)
{
startDocumentLoader();
}
}
BTW: Batik guys: Should the batik code read
something like: if (loader == null) loader = new
DocumentLoader(userAgent)
If it were written this way, I could just set the
loader and not have to overwrite this function. What do ya'll
think?
Also note that guaranteed was spelled
incorrectly. :)
PS: I may be making this too complicated, but it
worked. If anyone knows how to do it better, please let me
know!

I succeed in loading a SVG file in a
JSVGCanvas with the loadSVGDocument method.
But, how can I load a SVGDocument in a JSVGCanvas
without a file but a variable of this type?
Do I have to define a new class which inherits from
JSVGCanvas and redefine the paint method?
Thanks.
