Q: how to handle new tags in batik

["De Winne, Joris" <jo...@barco.com>]

Hello,

I'm having the following (extended) tag in an SVG file:
....
<me:video source="10.10.0.1" posx="0" posy="0" posWidth="100"
posHeight="100"/>
...

To handle this I thought I had to write a new bridge extension, but it looks
like those only support Java Graphical things. What I need to do is opening
a socket and sending commands. So this has nothing to do with Java2D. Does
somebody know what I have to do, in order to handle this extra tag?

What I have in mind is something like the following class:

VideoExtension extends ... implements ... {

	... some code that calls showVideo for each video tag it finds
	
	public void showVideo(XMLAttributes, ....) {
		//here comes my own specific code
	}

	... some other handling code

}

Any help is welcome!

Joris

    I'm not sure why you think that video wouldn't qualify as a
'Java Graphical' thing.

    There is a subclass of Bridge called 'GenericBridge' that does
not create a GraphicsNode but is still called during the building
of the document.  It has one method 'handleElement'.  This will
get you called for each video tag.  I still think that you probably
_do_ want a GraphicsNode to display the video even if most of the
work of the GraphicsNode is deferred to other classes.
