minimal classes needed to use JSVGCanvas in applet
I am trying to reduce the size of the jar file used to contain classes
displaying svg.
I would like to reduce the size of this jar file and batik jars take
most percentage of space, I'd also don't want to use network loading of
classes.
Is there a lean distribution available with minimal functionality
defined for it?
Please do let me know of any info out there.
Thanks in advance.
Nirmesh.

Could anyone more familiar with Batik internals comment on the
proposal and/or regarding how was the SVG source generated (tool or by
hand?
I could then attempt to create 1) a patch to the documentation stating
it's outdated (by adding a note, for example) in install page [1] or
2) try to generate an updated SVG image. This would also help fixing
bug 44573. :-)

Thanks Cameron,
The onload for svg element is working so I will use it to add DOMCharacterDataModified listeners to other elements.
The other elements have variable ids so I need to follow this approach
to wait till svg is loaded.

Here’s an example:
<svg xmlns='http://www.w3.org/2000/svg' width='400' height='300' font-size='18'>
<title id='title'>Initial title</title>
<text x='20' y='30'>Document title: “<tspan id='t'> </tspan>”</text>
<rect x='20' y='60' width='30' height='30'
onclick='title.firstChild.nodeValue = "Hello!"'/>
<text x='60' y='80'>← click to change title</text>
<script>
var title = document.getElementById('title');
var t = document.getElementById('t');
function update(evt) {
t.firstChild.nodeValue = title.firstChild.nodeValue;
}
title.addEventListener('DOMCharacterDataModified', update, false);
update();
</script>
</svg>

Thanks.
Is there a place where I can add this listener to appropriate nodes?
Currently onload throws error in batik saying the function not found.
Where can I add this line without using ui (mouse/keyboard) events..
node.addEventListener('DOMCharacterDataModified', doSomething, false);
Thanks again in advance.
Nirmesh.

Yes, you can listen for a DOMCharacterDataModified event:

svg event on text value change
Posted by Nirmesh Desai <nd...@cardiff.com>.
Is there an event for 'text' node's value change?
I had managed to use DOMAttrModified event to get updates relayed to
other elements
However I do not want to add attribute just to use the listener, is a
direct event on text content change?
Thanks,
Nirmesh.

Badly written - I should have stated that I read the post quickly (and
didn't analyze the instructions carefully)... :-|
Said that (and thinking about it), I'd propose "batik-anim.jar" to be
placed next to "batik-svg-dom.jar" with a double arrow (they depend on
each other), and "batik-coded.jar" below "batik-transcoder.jar" (which
intuitively depends on codec availability). Do agree on this? Is any
tool is used to edit the graph or was it made by hand? (I could try to
create an updated version, at least containing the two missing ones,
until the whole dependency graph is revisited...)

My reply to that thread shows how to extract the current dependencies

AFAIK no/not yet! Would you provide one? ;-) I've been trying to
gather this kind of information and expect 1) to discuss it with Batik
developers and 2) possibly publish it in the Wiki [1] afterward. :-)
The only thing is that I don't have a notion of when will I be able to
do that... :-|
> None provided by the project. We do publish the jar file

In the meantime, based in the available dependency graph [2] (as
Thomas Deweese has pointed out), I suggest the following:
xml-apis.jar,
batik-ext.jar,batik-gui-util.jar,batik-util.jar,
batik-xml.jar,batik-css.jar,batik-awt-util.jar,
batik-parser.jar,batik-gvt.jar,batik-dom.jar, xerces_2_5_0.jar,
batik-svg-dom.jar,js.jar,batik-script.jar,
batik-bridge.jar,
batik-anim.jar,batik-extension.jar,batik-swing.jar,xml-apis-ext.jar,
Each line is a row in the dependency graph, inverted order so that
dependencies get orderly downloaded.
Note that it assumes a somehow recent JRE (1.5+?) in order to leave
xalan out (the heaviest one).
I haven't yet found a place in the dependency graph for
"batik-anim.jar" (or "batik-codec.jar", but that's not required to
view SVG content). I recall a thread on the subject [2] but no
conclusion was reached. Could anyone suggest the order for these?
Hope this helps,

None provided by the project. We do publish the jar file
dependency list which might allow you to prune at that level.
In general if any part of a jar file is used we probably can
make use of all the contents of the jar file (depending on
SVG content).
