How to get the element form SVG file.
Hello:
I am new about the Batik. It has a big API. Now I want to get the
element from a SVG file and then draw the same thing using java2D. Could
someone give me some idea or suggestion.
Thank you in advanced.

Hello:
Thanks a lot for your help. But so pity, i have not achieved it. I just
use your demo code now, and when i run my java3D code, your code is running
and i could get a lot of bufferedimage. Now, when i click one key or mouse
button, i could call one method which is in your file. So i think i create
one method like that:
AWTEventDispatcher ad = new AWTEventDispatcher();
public void interactive(){
ctx.addDOMListeners();
ad.setRootNode(gvtRoot);
ad.mouseClicked((MouseEvent) *evt*);
manager.getUpdateRunnableQueue();
}
is that right?
and I do not know how to use the evt, for the java 3d, i just could call
the method, but i do now know how to transform the parameter now. For the
basic way, I just want that when i press one button or click the mouse, i
could call the method and then i could get the new Bufferedimage.
Sorry to trouble you again.
Thank you very much.

You need to construct your own instance, and then call
'setRootNode(gvtRoot)'.
You may also need to notify it of the 'baseTransform' Which is the mapping
from
the screen coordinates to the documents coordinate system (the rendering
transform).

I'm not sure I follow but, 'mouseClicked' should be called in the
UpdateManager thread...

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello thomas:
Thanks a lot for your help. There is only one problem left for me
that how to use the "batik.gvt.event.AWTEventDispatcher" to add the
interactive event. Now i use one simple SVG file for test, only one event of
clicking left button of mouse. I found there is a method of
"*mouseClicked*<file:///D:/Book/batik-doc/org/apache/batik/gvt/event/AWTEventDispatcher.html#mouseClicked(java.awt.event.MouseEvent)>
(MouseEvent<http://java.sun.com/j2se/1.3/docs/api/java/awt/event/MouseEvent.html>
evt)" in the class of batik.gvt.event.AWTEventDispatcher. But in your demo
file, there are some objects of manager, document, gvtRoot. which one i
could use to call that method? or i need to create a new object, but how to
make the connetion with the current SVG file. And then as you said, i just
need to add one line of manager.getUpdateRunnableQueue();
is it right?
If it is possible, could you show me some code?
Thank you very much.
zhao long.

Batik does not support SMIL animation at the moment. Cameron has
started
to add some support in the animation branch, also you might look at Doug
Schepters SMIL Script, which is part of SMIL animation written in
JavaScript.

Generally you just need to make the sure the DOM Event listener
get's called. This is done by dispatching the event to the GVT tree.
The code Batik uses for this is in batik.gvt.event.AWTEventDispatcher.
Once the event is dispatched it will normally modify the document which
will
cause the update manager to run and hence the BufferedImage to be updated.
You must dispatch the event to the GVT tree in the UpdateManager's
RunnableQueue or else it won't notice the changes.

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello thomas:
Thanks a lot for your help, and coached by your word, the animaiton
has been added on the java3D object. But, i could only use the animation
controled by the javascript, if you use some animation which is controled by
the tag named <animateTransform>, it does not work. Also for your code, it
could not generate the different .png files. What is this problem, shold i
add some new functions?
And next step for me is to add the interaction. I want to know how i
could tell the svg file that i have pressed one button,and then i could get
the result (bufferedimages), so i need to rewrite the javascript to java?
please give me some suggestion, i will follow your help to do.
Thank you very much

Why are you still generating PNG files? You should delete to code
that
saves PNG and just use BufferedImage.

I suspect you want to remove this code from the end of main:
for (int i=1; i<10; i++) {
final int x = 100+ (i*10);
try {
rq.invokeAndWait(new Runnable() {
public void run() {
rect.setAttributeNS(null, "x", ""+x);
}
});
} catch (InterruptedException ie) {
ie.printStackTrace();
}
}
render.manager.suspend();
In particular the last line stops the updatemanager so no more
updates will be delivered. If you just delete all of this code you
should get an endless supply of calls to the 'render' method...

Hello thomas:
Thanks for your words, it works well now. And for the SVG animation of
"3D.svg", i could only get 4 or 5 .png files. If i change the display size,
i could get more .png files. They are from the bufferedimage that is just
what i need. But i want to know why they have limited numbers. I want to get
a lot of bufferedimages, not stoping as the animation. what should i do?
please give me a idea.
Thank you very much.

anne.svg in batik sample directory contains reference to batikLogo.svg
in the same directory. So if you move anne.svg out from the sample
directory, you also need to copy / move batikLogo.svg as well. If not
the reference will be broken

Hello thomas:
In your code, you have already used the toString way.
File f = new File("anne.svg");
doc = df.createSVGDocument(f.toURL().toString());
I use the annd.svg directly here. When i run your code, it also shows
the error of
An I/O error occured while processing the URI:
"batikLogo.svg#Batik_Tag_Box"
specified on the element <use>
if i delete the element of use in anne.svg , it works well. Is it
strange or i should not input the file name directly.
Thank you very much

You need to map the pointer from Java3D to the u & v of the 3D object

I can help much more here since I don't know anything about Java3D besides
general knowledge of the basics of 3D.

I would suggest using the code from the TestOffScreenRendering. Trying
to use the Canvas is likely to be problematic.

I really think that using the JSVGCanvas will be more problematic
down the road.

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello thomas:
Thanks for your help and excuse me to trouble you again.
First, as your said, i should use the URL, but not the URI. But i can
not find any method that supports URL in many "DocumentFactory" classes. All
of them use URI, and i find it use the "inputstream" in the main method of
"createDocument" of the class "SAXSVGDocumentFactory" how could i do?
Another thing is you said i should use "
batik.gvt.event.AWTEventDispatcher" to add the events to java3D. i want to
know whether it is in the bufferedimage, and then when i add it as a
texture, it could work, or i have to set one area for one button of the SVG
in the 3D object.
From the article named "BatikRenderingSummary", it said the method "
installSVGDocument()" could do the 5 steps automaticly, Is it possible for
me to use that method or some methods like that to get a bufferedimage and
then add it to my 3D world.
As you said, the JSVGComponent uses the bufferedimage to show
everything. The only difference is i add the bufferedimage to Java3D, and
the Batik has existing method for JComponent. but i did find a method that
add the bufferedimage to the JComponent, if i could find it, what i need to
do just add it to java3D? Is it right and possible?
Thanks a lot.

Ok, then you will need to provide a Java3D replacement for the
batik.gvt.event.AWTEventDispatcher that dispatches mouse/keyboard
events from Java3D into the GVT tree.

This is probably because you are giving Batik an InputStream rather
than a URL. When you give Batik an InputStream Batik doesn't know
where the SVG content came from, so when it gets a relative reference
to another file it can't find it. It is best to always give Batik
a URL when possible.

Actually I think the problem is that my sample code doesn't dispatch
the 'onload' event. I think this is as simple as adding the line:
manager.dispatchSVGLoadEvent();
I've updated the Wiki Page so it now calls onload handlers. The
original example was oriented around getting updates as Java manipulated
the document not JavaScript.

Yes, this is correct. This method is called after the offscreen image
is updated.

slow.
I don't know, I've never done anything with Java3D. Internally Batik
uses Single or Double buffering so there is really only one or two
BufferedImages
that are passed to this method.

Yes, this is what the component does. It copies the modified regions
to
the screen when this callback is called by the update manager.

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello:
Thanks a lot for your help. Now i know how to run your code. For the
interaction, it is like the mines.svg that i could play the simple game on
one plane of a java3D object.
Now there are some problems that when i use some SVG file with a element
named "use", i could get the error
"batikLogo.svg#Batik_Tag_Box"
specified on the element <use>
at org.apache.batik.bridge.BridgeContext.getReferencedElement(Unknown
Source)
.....
if i delete the element of "use" in the SVG file, it works. It happened
as i use the "anne.svg". But, for some animation SVG file like 3D.svg, I
have to use that element, otherwise, i can not get the animaition. it seems
it is the interface of the javascript. is it right? how could i do?
For your code, that seems when the bufferedimage changed, i could get a
new bufferedimage,
manager.addUpdateManagerListener(new UpdateManagerAdapter() {
public void updateCompleted(UpdateManagerEvent e) {
}
is it right? and then, i could add the bufferedimage to my java3d
object. Do you think that will waste a lot of memory, and everything will be
slow.
Is it the same structure as the SVG rendering in JSVGComponent.
Same every frame in bufferedimage, and then when bufferedimage changed, show
the new one.
Thank you very much.
Waiting for your perfect help.

I'm not sure what you mean by 'interaction'. The sample code I
gave should run script and update the BufferedImage (you will be
notified when the image changes by it calling the
'render(BufferedImage)' method).
If you want to handle interaction like 'pointer' and 'key' events.
Then you will have to map a cursor position to the coordinate system
of the root of the SVG document and dispatch it to the AWT tree by
implementing the batik.gvt.event.EventDispatcher interface.

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello:
Thanks a lot for your help. Why i have to use the bufferedimage is
the Java3D texture only support the bufferedimage. Now it seems the batik
could render SVG using the DynamicRenderer to save the animation to the
bufferedimage, and i think i could add the animation to Java3D texture
through the bufferedimage. But for the interaction, could it work well
through the bufferedimage? or i have to use another way to transform the
javascript to java.
Thank you again.

I added this line to avoid a problem where it would decide to
'skip frames' because the updates had come too quickly. This is good
for the normal usage of updating a screen (and is likely also good for
your case as well) but is bad in the context of trying to 'record' the
image after each runnable.
This method is only in the SVN version of Batik. (I should add a
comment to the example to this effect).

You have to provide the filename of an SVG file to load as the
'background' to the animation. For my testing I used 'samples/anne.svg'.
I'll add a println to this effect in the example when args.length is zero.

Re: How to get the element form SVG file.
Posted by comlong zhao <co...@gmail.com>.
Hello thomas:
Thanks a lot for your code. That is much useful for me and i am
learning it line by line. I found it was created by you, so I want to ask
what is the method in line 94(manager.setMinRepaintTime(-1)) which is
undefined by my eclipse and i also can not find from the API. If i remove
this line, it could not work too.
The error is
"Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at Example.TestOffScreenRender.main(TestOffScreenRender.java:150)"
How could i run it?
Thank you again.
zhao long

Hi Zhao,
You probably want to read:
http://wiki.apache.org/xmlgraphics-batik/DynamicSvgOffscreen
This renders an SVG to an offscreen buffer. This code even
handles updating
the offscreen buffer if the SVG Document is changed (I don't know if this
is useful to you).

Hello:
Thanks a lot. I will try it. What is the result i want to get is saving
the SVG into the Butteredimage and then add it as texture in java3D. Now it
seems i do not need to draw it using java2D, but does Batik support svg to
butteredimage directly? could someone give me some ideas or suggestions. If
you have code demo, that's best. ;)
Thank you very much.
Thank thomas.deweese

Well all of Batik's drawing is done using Java2D so perhaps you
need to do nothing. Once you have read the SVG file and built the
GVT tree (see Wiki HowTo section on booting SVG DOM). You can
get the GVT element for any node in the DOM by asking the
BridgeContext:
Element x = document.getElementById("foo");
GraphicsNode gn = bridgeContext.getGraphicsNode(x);
GraphicsNode has a method 'paint' that takes a standard
Graphics2D.
