Re: SVG BufferedImage Quality
Hi Mark,
As far as I know, ImageTranscoder does not supply specific antialias
hints. Maybe you can try a shape-rendering attribute on the svg?

Re: Adding links to a document
This prob won't compile, and some methods may be misnamed, but it should be
close in spirit!
note that you need to use the xlink namespace for the xlink:href attribute
as shown below. Since a node can only be in one place I chose to use the
shorcut of adding n to a and letting the dom remove it from n.parent.
hope it helps
...
SVGElement a = null;
for(int i=0;ilabels.getLength();i++) {
n = labels.item(i);
log.info(A label:+n.getFirstChild().**getNodeValue());
//presumably, replace n with a link element that contains n?
a = document.createElementNS(SVGNAMESPACE, a);
a.setAttributeNS(XLINKNAMESPACE, xlink;href, my_special_url);
n.getParentNode().appendChild(a);
a.appendChild(n);
}

Is it a bug in batik? According to the javadoc of the getUpdateManager()

Re: getBBox() returns null
I'd also advise the changes be made in a single runnable as Thomas suggested. If you want a proof of concept for that, I'd point to some rather old, but potentially useful code I wrote awhile ago...seems to be doing something similar to what you want...look towards the end of the conversation for the inlined example: http://batik.2283329.n4.nabble.com/Status-of-FlowRoot-Overflow-Detection-td2979431.html On Thu, Sep 27, 2012 at 6:04 PM, DeWeese Thomas thomas.dewe...@gmail.comwrote: Hi fireball, I suggest that you add the content and then set the properties. Otherwise the result of getBBox may well be wrong. There are many properties that affect how text is rendered that will be inherited where the element is inserted in the document, so any calculation you make outside of it's final place in the document has a decent chance of being wrong. If you add it and set the properties in one Runnable (sent to the UpdateManager's RunnableQueue) then it won't be rendered until your runnable exits. If you really need to do this outside of the document (and I strong recommend against it in general) you can check out the link Jonathan gave for booting the SVG CSS Dom. However once again I must point out that for that to give you useful results the CSS context must be the same as where it will eventually be inserted into the document.

You may be accessing the document before the gvt builder is complete... try
adding a listener and then loading the doc. Begin your work when the
listener is called...
canvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {

In that case I think you need to send a sample document that shows the

Re: Broken image
Hi fireball, You may not be resolving the url properly - You may need to call SVGOMDocument.setDocumentURI() or set the xml:base attribute in the svg document.

Re: Read/Write transform values

Thanks! Jonathan.
This makes things much cleaner and easier to deal with.
The only thing is rotation. It does not sound straight forward like the
other values (translate, shear, scale).
Is there a simple way to set/get rotate value?
I tried something like this for setting it but it did not work:
String strTransform = elt.getAttributeNS(null,
SVGConstants.SVG_TRANSFORM_ATTRIBUTE);
TransformListParser p = new TransformListParser();
AWTTransformProducer tp = new AWTTransformProducer();
p.setTransformListHandler(tp);
p.parse(strTransform);
AffineTransform at = tp.getAffineTransform();
at.rotate(Math.toRadians(Double.valueOf(rotateAngle)));
This looks correctdid you also replace your original transform with
this one?
Something like this:
...
el.setAttributeNS(null, SVGConstants.SVG_TRANSFORM_ATTRIBUTE,
affineTransformToString(at));
public String affineTransformToString(final AffineTransform at) {
double[] matrix = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0};
at.getMatrix(matrix);
return matrixArrayToString(matrix);
}
public String matrixArrayToString(double[] vals) {
return new StringBuilder(matrix().append(vals[0]).append(
).append(vals[1]).append( ).append(vals[2]).append(
).append(vals[3]).append( ).append(vals[4]).append(
).append(vals[5]).append() ).toString();
}
For getting it I had to parse the transform string myself to get rotate
value.
Note that my transform is like this: transform=matrix(a,b,c,d,e,f)
rotate(angle). Should rotate be part of the matrix?
both are correct. I tend to use matrix only because of
TransformListParser/AffineTransform, but that does not mean you can't
concat multiple matrices, or explicit transforms like rotate/scale...
Any thoughts?

Re: Issue with dragging shapes
I've found it best to handle mousedown on the element being dragged, then
track all mm/mu on a glasspane above the elements to be dragged.

svg = document.documentElement;
var rect = document.getElementById(draggable);
rect.addEventListener(mousedown, md, false);
svg.addEventListener(mousemove, mm, false);
svg.addEventListener(mouseup, mu, false);
}
function md(e) {
drag = true;
draggable = e.currentTarget;
}
function mu(e) {
drag = false;
}
function mm(e) {
if (drag) {
var p = getPoint(e);
var m = svg.createSVGMatrix().translate(p.x, p.y);
var transform = matrix( + m.a + + m.b + + m.c +

draggable.setAttributeNS(null, transform, transform);
}
}
function getPoint(e) {
var p = svg.createSVGPoint();
p.x = e.clientX;
p.y = e.clientY;
p = p.matrixTransform(svg.getScreenCTM().inverse());
return p;
}

Major: I can't drag shapes over others. I have to drag them around for it

Does it have to do with the way I add shapes to the DOM document or the way
I handle the dragging, or is it both, or is it something else?
Minor: Moving mouse too fast after a mousedown loses the shape (shape stops
moving) but when I go back to it the handle is still there and the shape
keeps moving with the mouse without re-clicking on it. Same behaviour as in
the major case above. What would be the cause?
I register a handler object which listens to mousedown, mousemove, and
mouseup for any object that is draggable. I do keep track of initial points
to re-adjust the position. Something similar to
http://wiki.apache.org/xmlgraphics-batik/DragTutorial
Please let me know if you need to see any code for more info.

Re: receiving error rendering Corel file
It really depends on what you want to do ... - You could remove the offending tags via a preprocess step using xslt or the like. That assumes the tag is of no value to the rasterizing process. http://xml.apache.org/xalan-j/commandline.html is a starting place - You might consider extending Batik to handle the custom elements http://xmlgraphics.apache.org/batik/using/extending.html#customXMLTags - If you can control the svg output you might look to produce a spec compliant document using metadata.

A couple of things I noted while reading your post: The transcoder is trying to create an a tag/element named odm in the svg namespace, which does not exist. Maybe you need an additional namespace in your doc to help resolve this tag? The doctype MAY be problematic, but does not appear to be at the heart of the issue IMHO. -- read this for the rationale behind dropping svg/doctype: https://jwatt.org/svg/authoring/#doctype-declaration I don't think your classpath is an issue at the moment.

Re: PDFTranscoder is producing 0byte file
Your high resolution vector image may be consuming more heap than you have available when transcoding to raster. You can test this by passing an AOI to the transcode hints. if that is the issue, you can opt to tile the output http://xmlgraphics.apache.org/batik/using/transcoder.html#selectAreaOfIntrest Or cut your resolution by reducing the magnitude of your cords... you'll get some better answers from other, more knowledgable transcoders!

Description of the problem:
If you have a program that reads XML files and you add
xerces_2_5_0.jar to
your CLASSPATH on a HP-UX machine (or any other machine that has
proprietary
XML encodings) then the program may fail with the exception
org.xml.sax.SAXParseException: Invalid encoding name HP-ROMAN8.
Note that the existence of this jar in the CLASSPATH is sufficient to
make
this happen. The following test program illustrates the issue (forgive
the
deprecation warning):
import org.xml.sax.InputSource;
import javax.xml.parsers.SAXParserFactory;
import java.io.StringBufferInputStream;
public class EncodingTest
{
public static void main(String[] args) throws Exception
{
SAXParserFactory.newInstance().newSAXParser().getXMLReader().parse(new
InputSource(new StringBufferInputStream(?xml version=\1.0\
encoding=\HP-ROMAN8\? )));
}
}
Consider the following invocations:
Example 1:
$(unset CLASSPATH;java -Djaxp.debug=1 EncodingTest)

Example 2:

-Djaxp.debug=1 EncodingTest)
JAXP: find factoryId =javax.xml.parsers.SAXParserFactory
JAXP: found jar

Now, the issue can be fixed by forcing the JVM to use the default

settings the property javax.xml.parsers.SAXParserFactory as described in

1) Is it necessary to include xerces_2_5_0.jar in the CLASSPATH?

Re: Exporting a RadialGradientPaint
Hi Ryan,
Although Batik most certainly supports radial gradients, I'm not sure that
support currently extends to the SVGGraphics2D arena. You can likely add
support for it quickly though by extending DefaultExtensionHandler and
overriding the handlePaint method...something like this...
public class RadialGradientPaintExtensionHander extends
DefaultExtensionHandler {
@Override
public SVGPaintDescriptor handlePaint(Paint paint, SVGGeneratorContext
svggc) {
if(paint instanceof RadialGradientPaint) {
// create svg radial gradient dom elements
...
// return an extension of SVGPaintDescriptor appropriate for
this radial gradient
}
return null;
}
}
You can also use the dom directly and then transcode the resulting document,
but that is an entirely different approach.
Hope this helps,
jonathan

Hi All,
I just started learning Batik and I'm really amazed by it so far! I'm
kind of new to SVG to please bear with me.
I've got a Java 2D method that draws a circle of nodes connected by
edges. Each node is drawn using a java.awt.RadialGradientPaint (see
attached circle_swing.png).
When I try to render this to an SVG using SVGGraphics2D everything
goes fine except that the nodes are drawn as a solid color, which I
believe is the color of the last node. (see attached circle_svg.png
and circle.svg).
How can I get the radial gradients to draw properly? I've read that
they exist in SVG and the Batik status list says they're supported
currently.
The export code I'm using is a direct port of the tutorial here:
http://xmlgraphics.apache.org/batik/using/svg-generator.html
I'm using the latest SVN of Batik on OS X Lion with the Apple JRE.

Re: rendering directly to java.awt.Graphics2D
Hi Mike,
I've seen variations of this type thing before... in my case a top level
svg that contains an image who's xlink:href references another document
(svg in my case). The referenced svg document had an id'd gradient that was
in the defs...when the gradient was referenced by a shape's fill, the
transcode would fail. Seems once the DOM (GVT) is booted the calls out to
the xlnk:href are resolved. The uri for the embedded document seemed to be
null (null#id on reference)You can try to setDocumentURI(something) on the
parent...I think I tried that with no success, but needed to work-around
(base64 data uri worked fine) and move on. I can probably reproduce this
behavior in a test case if you think it will help resolve your issue. I
have not had time to debug it further, but it is on the (long) list.

I'd like to be able to render (and animate) SVG drawings directly onto
a java.awt.Graphics2D instance. However, I'm having a bit of trouble
figuring out how exactly to do that with batik. I *think* that I need
to decode my SVG drawing into a GVT tree, and then render the tree.
However I can't figure out which part of batik I need in order to do
the rendering. Transcoder and SVGGraphics2D do not seem to be quite
what I want. Actually, I haven't yet figured out the
decoding-to-GVT-step either, but I'm assuming that's pretty
straightforward.
So can anyone give me a pointer on how to do this? Perhaps just point
me to an existing example? My first goal is to just get static images
rendering.
After that, I'll need to get animation working. I'm assuming that
supporting animation will entail updating the drawing's current time
every so oftern on a separate thread, via the AnimationEngine, and
then re-rendering the updated GVT?
I *could* do all this by rendering into a static java.awt.Image, and
then bliting the Image (i.e. roll my own double-buffering), but I'd
prefer to figure out how to just draw directly onto a Graphics2D
instance first. That's because the framework I'm using already has
some double-buffering, so I most likely wont need to do that with the
SVG rendering.

P.S. FYI, I'll probably never need to support handling interactive user
input.
OK, I have discovered the GraphicsNode.paint(Graphics2D g2d) method,
which may be all I need to call once I actually get a valid GVT build.
However, I'm having trouble building a GVT from a

String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);

bctx.setDynamicState( BridgeContext.DYNAMIC );
GVTBuilder builder = new GVTBuilder();
this.gvtRoot = builder.build(bctx, document);
This code fails at the call to GVTBuilder.build(), with the following
error:

Hello,
I'm using batik to display SVG files on a JSVGCanvas and I'm trying to
respond to mouse click events over SVG elements with tags a
(SVGOMAElement) and g (SVGOMGElement).
Here is the code I'm using to add the event listener to a Node:
if ((no.getNodeName().equalsIgnoreCase(a)) ||
(no.getNodeName().equalsIgnoreCase(g))) {
EventTarget etr = (EventTarget) no;
etr.addEventListener(SVGConstants.SVG_EVENT_CLICK, new EventListener()
{
public void handleEvent(Event evt) {
Log.debug(HANDLE EVENT);
}
}, false);
What happens is that the listener is correcly called when an a element
is clicked, but nothing happens when a g element is clicked!
I debuged the code above and verified that the click listener is being
added to the both node's bubblingListeners table
(etr-eventSupport-bubblingListeners). However, I noticed that the a
elements seem to have two other (default) listeners - for events mouseout
and mouseover - which are not present on the g elements. I don't believe
this is the cause, but ...
Any ideas on what could be causing this behaviour?
Regards,
ABrito

Re: Batik and JUnit
Without some context (code snippet, svg sample, etc), I'm a bit limited in
the help I can offer.
I've seen odd behavior like this in 2 cases...Yours may not fall into either
since it works outside the unit test, but it's worth a shot.
1) The document is tampered with before SVG/GVT are fully initialized.
Using the following eliminates the need for sleep/check routines for a
loaded doc. Note the comments indicating proper/improper places to begin
document modification.
Example:
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
svgCanvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
//MODIFY DOCUMENT HERE
}
});
InputStream templateStream =
Canvas.class.getResourceAsStream(mydoc.svg);
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
SVGDocument doc = null;
try {
doc = f.createSVGDocument(null, templateStream);
} catch (IOException ex) {
Logger.getLogger(Canvas.class.getName()).log(Level.SEVERE, null,
ex);
} finally {
if(templateStream != null) {
try {
templateStream.close();
} catch (IOException ex) {
logger.log(Level.WARNING, null, ex);
}
}
}
doc.setDocumentURI(myuri);
// DON'T MODIFY DOCUMENT HERE
2) Modification of the document (add/remove/update any svg node) outside of
the UpdateRunnableQueue. All modifications should be wrapped..
getUpdateManager().getUpdateRunnableQueue().invokeLater(new Runnable() {
@Override
public void run() {
// MODIFY DOCUMENT HERE
}
});

Re: Batik problems in Cocoon 2.2
Greetings,
This is almost certainly a namespace issue. I'd suggest the
following 3 things:
- Check and/or post your parse sequence using SAXSVGDocumentFactory.
(less likely if unchange during upgrades)
- Check and/or post(if of appropriate size) your raw input document.
(less likely if unchange during upgrades)
- Check your classpath for duplicate (xmlparsing?) jars with
differing versions.
Happy to help further if needed... more detail always useful.

Hello, I'm trying to get Batik 1.7 running in Cocoon 2.2. I think I should
start from the beginning.
I'm moving from Cocoon 2.1 to 2.2 (2.2 uses maven for everything), I created
the webapp and tried to use the fop-block in cocoon but the fop version it
wants to use is 0.20.5 and batik-1.6. The problem is that with that
combination embedded SVGs wont work in fop. I downloaded the fop-ng-block
and now have a working cocoon 2.2 with fop-1.0 and batik-1.7.
My problem is that now the SVGSerializer (converts SVG to jpeg) part of
cocoon does not work. It gives me the following error:
java.lang.NullPointerException
at
org.apache.batik.dom.util.SAXDocumentFactory.startElement(SAXDocumentFactory.java:563)
.
The problem is in this part of startElement() for some reason, parser is
null:
if (inProlog) {
inProlog = false;
try {
isStandalone =
parser.getFeature(http://xml.org/sax/features/is-standalone;);
} catch (SAXNotRecognizedException ex) {
}
try {
xmlVersion = (String)
parser.getProperty(http://xml.org/sax/properties/document-xml-version;);
} catch (SAXNotRecognizedException ex) {
}
}
I moved both trys to the createDocument(InputSource is) since it just saves
those 2 values (why are those trys in startElement and not createDocument?).
After moving both trys thingts moved along and it crashes on the transcoding
part. The error I get is:
java.lang.ClassCastException: org.apache.batik.dom.GenericElement cannot be
cast to org.w3c.dom.svg.SVGSVGElement
the code for transcode is:
public void notify(Document doc) throws SAXException {
try {
TranscoderInput transInput = new TranscoderInput(doc);
// Buffering is done by the pipeline (See shouldSetContentLength)
TranscoderOutput transOutput = new TranscoderOutput(this.output);
transcoder.transcode(transInput, transOutput);
} catch (TranscoderException ex) {
...
} catch (Exception ex) {
...
}
}
after reading through a lot of posts I found one saying
DOMUtilities.deepCloneDocument would convert dom to Batik's own DOM and do
the transcode. I changed the TransocderInput constructor to this:
TranscoderInput transInput = new
TranscoderInput(DOMUtilities.deepCloneDocument(doc,SVGDOMImplementation.getDOMImplementation()));
but it still gives me the same error, so I'm officially stuck. I hope
someone here can help me, asked at the cocoon list 3 times and got no
response.

Re: Batik and XmlHttpRequest / accessing Batik objects from javascript in svg
Hello Roland,
I have not tried to reproduce your problem, the items below are wild
guesses...
- Change the method call order ...
1. set always dynamic
2. assign listener.
3. load doc.
This may not be the issue since your listener is called, but it may
also be fortunate timing?
- I've found it most opportune to start my document manipulations
using the following listener override...
mysvgCanvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
// do stuff with doc here
}
}

Hi again,
ok, maybe i should describe the problem again :-)
What I'm doing is to use JSVGCanvas inside an applet as an svg-viewer inside
the browser. In the applet's init()-method I create a new canvas
(MySVGCanvas is as already explained simply derived from JSVGCanvas in order
to have access to the protected contextBridge-field of the canvas, see
Listing 2) and set the document of the canvas via canvas.setURI().
So what I try to achieve is that after the SVG is loaded into the canvas,
the canvas object itself (the java object) should be bound to the
script-interpreter of the document (just as Thomas Deweese pointed out
earlier in this mail-thread). This should allow me to access the
canvas-object from inside the ecmascript of the SVG as a global variable
named mycanvas. This is done by calling my BindToInterpreter-method of class
MySVGCanvas inside the DocumentLoaderListener. Unfortunately, this throws an
exception, because the internal document-field of the interpreter is not
set, it is null (Exception was posted before). The question is: What am I
doing wrong, why does the interpreter not have a document set (the svg is
running perfectly inside the canvas, it is displayed correctly and the
ecmascript is working also). I hope this disruption of the problem is more
useful. All I want to do is bind a java-object to the interpreter in order
to access it from inside ecmascript.
Listing 1: The Applet
public class IntercomApplet extends JApplet {
protected MySVGCanvas canvas;
protected JSObject jso;
public void init() {
// Create a new JSVGCanvas.
canvas = new MySVGCanvas();
getContentPane().add(Center, canvas);
try {
// Set the document by using an URI
canvas.setURI (getWorkflowURL ());
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
// Set the JSVGCanvas listeners.
canvas.addSVGDocumentLoaderListener(new
SVGDocumentLoaderAdapter() {
public void documentLoadingStarted(SVGDocumentLoaderEvent e)
{
}
public void documentLoadingCompleted(SVGDocumentLoaderEvent
e) {
System.out.println(### Document loaded);
// try to bind the canvas object und name myycanvas to the
script interpreter
canvas.bindObjectToInterpreter(text/ecmascript,
mycanvas, canvas);
}
});
} catch (Exception ex) {
ex.printStackTrace();
}
}
public String getWorkflowURL (){
String codebase = getCodeBase().toString();
String myurl = codebase + getParameter (svgurl);
return myurl;
}
}
Listing 2: MyCanvas
public class MySVGCanvas extends JSVGCanvas {
public void bindObjectToInterpreter(String language, String name,
Object obj){
System.out.println(### Binding Object + obj.toString() + to
interpreter.);
Interpreter interpreter =
this.bridgeContext.getInterpreter(language);
interpreter.bindObject(name, obj);
}
}

Betreff: Re: Batik and XmlHttpRequest / accessing Batik objects from
javascript in svg
Hi there,
Hi Roland,
The difficulty is WHEN to bind the object. First try was to simply call it
in the init()-Method of the Applet after using canvas.setURI(…). However,
this method is async, so my bind-method will not yet find even a
bridgeContext (it is null). Therefore, I thought it would be best to bind
the object AFTER the document is loaded (via setURI) by using something
like:
snippet/
Currently, this should bind the canvas (later it should be the applet) to
the name “parentapplet” in the interpreter and I should be able to use
this
name as a global variable in my ecmascript, e.g. like alert(parentapplet);
Correct? However, an exception is thrown when binding the object:
### Document loaded
### Binding Object

Re: Convert SVG to Java-Shapes?
Sorry for the terse answer...I assumed since you explicitly mentioned JSVGCanvas and ImageTranscoder that you were familiar with both. if you are transcodingobtain a BridgeContext using ImageTranscoder's (SVGAbstractTranscoder's) protected ctx variable or possibly createBridgeContext(). I'm not familiar with using the latter, although if you are maniplulating shapes, it may be easier to extend BridgeContext. if using JSVGCanvas, get the BridgeContext using myJSVGCanvas.getUpdateManager().getBridgeContext() In either case, use your SVGDocument to find the node you are interested in... Element el = document.getElementById(my-circle); Ask the previously retrieved BridgeContext for the GraphicsNode... GraphicsNode gn = ctx.getGraphicsNode(el); Carefully cast a Shape out of the fray... Shape shape = ((ShapeNode)gn).getShape(); If I recall correctly, this only works if the BridgeContext is dynamic or possibly interactive. Using JSVGCanvas with dynamic (setDocumentState(ALWAYS_DYNAMIC)) will most likely do the trick for simple use cases. All that said, if you are new to Batik, you may find an easier way using the standard DOM interfaces. Using the GVT to acquire graphics node info is usually not required.

What this means is that I have at least two (usually three!) representations of the image data in-memory – even before a subsequent transcode operation! (That is, one in a ByteArrayOutputStream to accumulate the data, one in the byte[] that ByteArrayOutputStream returns, and a third in the base-64 encoded version of that byte[].) The subsequent transcode operation will necessarily base-64 decode the data I just encoded, create a bitmap out of it, and presumably blit the bits into the resulting JPG. This is far too many large data structures floating around! To reduce the count of large data structures, I really want to specify in the href element that the image data should come from some InputStream I have at hand. Then when Batik processes the image element, it reads the InputStream directly, and creates only the one or two copies of the image data it really truly needs. Is there a way to do this? If not, can someone point me in the right direction if I were to take this on on my own? -Adam Maass
Re: Problem overlaying SVG element on top of loaded file
I have not tried your example, but you might try using the namespace aware

SVGConstants.SVG_CIRCLE_TAG);
and

How would you suggest setting the location of the elements? I need to

As for the translation, I found some code that does it differently. Is

SVGOMPoint pt = new SVGOMPoint(e.getX(), e.getY());
SVGMatrix mat = this.getSVGDocument().getRootElement().getScreenCTM(); //

pt = (SVGOMPoint) pt.matrixTransform(mat);
Again, thank you for the help.

Re: OK to rescale SVG in PDF by changing just width and height values?
Hi Joe, Be aware that some illustrator versions ( CS3?) can drop viewBox's upon export. This may only be true for automated exports via javascript, I don't recall. If you are looking to add to a command line toolkit for your automated document creation, you might look into using XSLT to modify the w/h values.

Is it possible to use Batik via the Windows command line to change the width and height values by a certain percentage? I'm not aware of a way to do that. You can set the width and height from the command line but you can't change them by a percentage. I read that the transcoder could change these values, but all the information I can find so far concerns the transcoder API; not anything directly accessible via the command line. If you run the rasterizer with no arguments it should print help text. I should have explained more clearly. I actually want to change the width and height values in the source SVG, as I'm using the SVG directly in PDFs. If Batik (from the command line) offered either a way to scale those by a certain percentage, or at least to get the original values and then change them, that would be very helpful. But it's looking like I need to use another tool. I'm using the rasterizer to convert the same SVGs for web output, not PDF. I just thought that as I need Batik for that, it would be neat if I could also use Batik to edit the source SVG for PDF output.

(and happy summer ^^) Im working on a project using Batik and dealing with SVG ! One part of this project consists in a kind of color inversion of some elements in the displayed SVG. In fact, only black(resp white) have to be converted in white(resp black). The first solution is to look for each SVG elements in the displayed SVG. For each element we can set the color to white/black. This solution is really slow ( more than a minute...) and this can't be acceptable. - Document state is ALWAYS_DYNAMIC if can help Another idea was to add an overlay, and inverting color of each pixel if required, but the result is not convincing, probably because of antialising and rendering of the graphic, which introduces gray level pixel. These pixel are not inverted by our overlay... and each refresh takes aout 2seconds ( well.. depends on the screen resolution in fact ^^) Do one of you have an idea on how to do this in optimisng performance(speed) and without grahics losts ?

Re: Rasterizing produces 2 empty IDAT chunks
This sounds like Bug 48693https://issues.apache.org/bugzilla/show_bug.cgi?id=48693. Can you review the current bug and verify that is is the same issue? If so, I may have a bit of time to investigate. On Tue, May 18, 2010 at 11:52 AM, IsmAvatar ismava...@gmail.com wrote: I guess this is a Bug Report The subject pretty much explains it all. Using Sun JDK 6u20, and batik checked out from the SVN repository, I use Rasterizer (actually RasterizerTask, but it calls Rasterizer, and I could reproduce it with Rasterizer if desired) on an SVG to generate a PNG. The PNG has 2 additional empty IDAT chunks immediately prior to the IEND chunk. These chunks cause the PNG to be erroneous (and thus not display) in certain programs, such as IE7, as well as Java programs that try to display the image (especially, as is my case, if attempting to use it as a Splash Screen). A sample SVG which may be used to reproduce this problem: http://svn2.xp-dev.com/svn/LateralGM/LateralGM/trunk/org/lateralgm/main/lgm-splash.svg Please do let me know if/when this has been fixed. I use RasterizerTask to automate the creation of my splash screen for my program while the program is being compiled and built for release, and since Batik's been generating these two extra IDAT chunks, my program runs without a splash screen.
Re: Rasterizing produces 2 empty IDAT chunks
Looks like a double close on an output stream...
I believe the solution is to apply the following to
org/apache/batik/ext/awt/image/codec/png/PNGImageEncoder.java, although I'd
rely on Thomas DeWeese or other committer to verify.
Summary of changes:
- removed DeflaterOutputStream.finish() since it is redundant
(DeflaterOutputStream.close() is called immediately after and performs the
same operation if in a single filter scenario)
- removed ios.flush() and ios.close() since DeflaterOutputStream claims to
complete the stream write and close the close the underlying stream

Can you review the current bug and verify that is is the same issue? If so,
I may have a bit of time to investigate.

I guess this is a Bug Report
The subject pretty much explains it all. Using Sun JDK 6u20, and batik
checked out from the SVN repository, I use Rasterizer (actually
RasterizerTask, but it calls Rasterizer, and I could reproduce it with
Rasterizer if desired) on an SVG to generate a PNG. The PNG has 2 additional
empty IDAT chunks immediately prior to the IEND chunk. These chunks cause
the PNG to be erroneous (and thus not display) in certain programs, such as
IE7, as well as Java programs that try to display the image (especially, as
is my case, if attempting to use it as a Splash Screen).
A sample SVG which may be used to reproduce this problem:
http://svn2.xp-dev.com/svn/LateralGM/LateralGM/trunk/org/lateralgm/main/lgm-splash.svg
Please do let me know if/when this has been fixed. I use RasterizerTask to
automate the creation of my splash screen for my program while the program
is being compiled and built for release, and since Batik's been generating
these two extra IDAT chunks, my program runs without a splash screen.
Re: How to resize an svg
Unless an alternate view/transform is specified, I believe that JSVGCanvas will honor the viewBox attribute. Check your svg input file to see if a viewBox attribute is present or insert one programmatically after it is loaded possibly. for instance...if you want the canvas to show all of your svg (100x100) no matter what the canvas size, use the following: svg viewBox=0 0 100 100 ...

Re: How to use org.apache.batik.bridge.UpdateManager?
Hello Rishabh, Narendra and Praveen,
A couple of observations:
You really have no context in which to manipulate the DOM until the
document is loaded. Your best bet is to add a GVTTreeBuilderListener.
Also, it is much easier to work directly with the DOM objects and let the
GVT take care of rendering the 2D.
Red the attached snippet carefully...the listener code is invoked after
the document is loaded.
private void runDemo() {
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
svgCanvas.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
svgCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable() {
public void run() {
Element rect =
svgCanvas.getSVGDocument().createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI,
SVGConstants.SVG_RECT_TAG);
rect.setAttributeNS(null,
SVGConstants.SVG_X_ATTRIBUTE, 100);
rect.setAttributeNS(null,
SVGConstants.SVG_Y_ATTRIBUTE, 100);
rect.setAttributeNS(null,
SVGConstants.SVG_WIDTH_ATTRIBUTE, 100);
rect.setAttributeNS(null,
SVGConstants.SVG_HEIGHT_ATTRIBUTE, 100);
rect.setAttributeNS(null,
SVGConstants.SVG_FILL_ATTRIBUTE, #ee);
svgCanvas.getSVGDocument().getDocumentElement().appendChild(rect);
}
});
}
});
Document doc =
SVGDOMImplementation.getDOMImplementation().createDocument(SVGDOMImplementation.SVG_NAMESPACE_URI,
svg, null);
svgCanvas.setSVGDocument((SVGDocument) doc);

Hello!
We are a team 3 students who are developing an opensource application
called Chart Glazer. The application helps the users draw charts (process
diagrams, organization charts etc.) easily. It is very much similar to
Microsoft Office 2007's SmartArt.
We're using Apache Batik and Java Swing for our development. Our project is
hosted at http://kenai.com/projects/chartglazer.
The FAQ at http://xmlgraphics.apache.org/batik/faq.html talks about using
the UpdateManager.
We are facing the exact same problem, as in section 3.3 of the FAQ, When I
change the document in Java it only updates if I move the mouse over the
canvas?
We have reproduced our problem into a smaller application (called
SVGApplication), using NetBeans. It has a JButton (called
loadDocumentJButton) and a JSVGCanvas (called myJSVGCanvas) present inside a
JScrollPane object.
Our requirement is that when we click this loadDocumentJButton button,
the the myJSVGCanvas object must display the myRectangle (see code
below.)
Here is the actionPerformed event handler for loadDocumentJButton...
private void loadDocumentJButtonActionPerformed(java.awt.event.ActionEvent
evt)
{
DOMImplementation myDOMImplementation =
SVGDOMImplementation.getDOMImplementation();
Document myDocument =
myDOMImplementation.createDocument(SVGDOMImplementation.SVG_NAMESPACE_URI,
svg, null);
Element svgRoot = myDocument.getDocumentElement();
SVGGraphics2D mySVGGraphics2D = new SVGGraphics2D(myDocument);
mySVGGraphics2D.setSVGCanvasSize(new Dimension(320, 240));
myJSVGCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
myJSVGCanvas.setDocument(myDocument);
Rectangle myRectangle = new Rectangle(10, 10, 60, 40);
mySVGGraphics2D.draw(myRectangle);
svgRoot.appendChild(mySVGGraphics2D.getRoot());
}
The rectangle is being displayed only when we move the mouse over the
myJSVGCanvas object in the Swing GUI window.
We understand that we must use UpdateManager to solve this problem. But we
don't know how to use it. We searched a lot on the Internet and
mail-archives, but we are not able to figure things out. We did not find any
example programs. If we get an example program that demonstrates the use of
UpdateManager, we will figure it out on our own. It would be great if you
provide us with such an example program.
Please help us.
We are attaching the 3 files of SVGApplication (created usingNetBeans)
for your reference. The above event handler function is located in the
SVGView.java. Probably, the other two files will not be required; we have
just attached it for completeness' sake.
Thank you very much!

Re: How to create a svg animate tag during runtime and animate it?
Hi Fabian,
Note that although the Elements in the example are created at the
beginning of the example, the listener code block runs after the document is
loaded (after theGVTTreeBuilderEvent is fired).

Re: coordinate conversion
Most of what you need can be found in SVGLocatable. The below is not tested, but should be close: Point awtPoint = ...; Element myEl = document.getElementById(my-el); SVGPoint svgPoint = document.getRootElement.createSVGPoint(); svgPoint.setX(awtPoint.getX()); svgPoint.setY(awtPoint.getY()); SVGMatrix m = ((SVGLocatable)myEl).getScreenCTM(); m = m.inverse(); svgPoint = svgPoint.matrixTransform(m); On Fri, Feb 26, 2010 at 8:34 AM, dao dao.ho...@gmail.com wrote: hello, Sorry for this stupid question: how do I transform coordinates from a AWT mouse event to the coordinates in the svg file the canvas represents?

Could you try to analyze the (supposedly PNG) raw file saved and/or attach it to a reply? No file is created in FF so there is nothing to analyze. And that MSIE BMP file is the standard image.

Re: problem with batik transcoder on a headless system
My previous response failed to note that Batik IS using the int version of the Color constructor. I would check the test svg carefully. Your working jvm (windows?) may be bounds checking and correcting the input values while your headless (possibly sun?) jdk does not (instead relies on an exception). As always. The test.svg file would probably help in resolution On Tue, Feb 9, 2010 at 1:56 PM, jonathan wood jonathanshaww...@gmail.com wrote: Hello Simon, I suspect the root of your problem is how the local vm is sorting/selecting the constructor for java.awt.Color. Your headless system is likely constructing using the float version of the Constructor which does something like: this( (int) (r*255+0.5), (int) (g*255+0.5), (int) (b*255+0.5)); Hence, if you are passing an int as the color value (very likely), you will blow the values far from the acceptable 0-255 range. The Constructor order seems to differ by platform and even by jdk revision on platforms. You can almost certainly verify this by check the stack while suspended at the exception. If you see the float constructor called prior to the int version then this is almost certainly the issue. Of course, if you could provide the failing test.svg for inspection, it might help to determine a suitable work-around. Hope this helps a bit and please share anything you find!

I'm not sure there are a lot of high priority bugs. I'll list a few things that have been on my TODO list (for a few years now ;). 1) Pipe all element lookups through an object associated with the BridgeContext. This would be to serve two purposes. First it would more easily enable people to 'replace' Batik's lookup/fetch logic (replacing/augmenting ParsedURL only goes so far). Second if paired with 'unlookup' calls it would enable Batik to detect complex reference loops in content (an element that references a pattern that uses the element). 2) Make everything use ParsedURL for references. Currently there are still a few places where we don't use ParsedURL (I think mostly in CSS) this mostly means that you can't use base64 encoded URLS in these places. 3) Add dynamic updates for referenced content. Currently in many cases if a referenced element changes Batik doesn't notice. I think this is true for patterns, filters, masks, etc. I did an example of dependency tracking for gradients (which may not have landed on trunk) at some point it would be nice if this was extended to other areas. 4) Implement ElementInstance for Use elements. Currently we create a shadow tree to support the use element, which is not conformant to the SVG specification. It would be better if we created ElementInstances that could carry the CSS cascade information and then use a reference to the actual element for DOM attributes. This would require updating all of the Bridges to know/handle the ElementInstance case but I think the changes (while widespread) could be fairly simple. These are just suggestions, let me know if these are the sorts of suggestions you are looking for, or if your interested lie in other areas. My Apache ICLA has been submitted and I do understand that I will be limited to submitting patches that may or may not be applied by an individual with commit access. Thanks, jonathan
Re: create a JSVGCanvas from an inputstream
Hi Dao,
I also included a load from jar in the previous examples. The key is
the line:
InputStream templateStream =
MyClass.class.getResourceAsStream(template.svg);
getResourceAsStream will allow you to load from the classpath (including
your jar).
to recap:
InputStream templateStream =
MyClass.class.getResourceAsStream(template.svg);
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
SVGDocument doc = null;
try {
doc = f.createSVGDocument(null, templateStream);
} catch (IOException ex) {

Re: create a JSVGCanvas from an inputstream
There may be a way to do this auto-magically, but I don't (yet) know it.
Try the jar protocol (jar:file://nn/file.svg) (
http://docs.sun.com/source/819-0913/author/jar.html#jarprotocol)
Override/extend the existing UserAgent.openLink() functionality. To save a
bit of hunting on your part...The appropriate code can be found in
JSVGComponent.BridgeUserAgent() (
You'll likely receive better guidance from the others on the list though.
I'll update you if I see something better.

Hi dao,
Response inline...
Added in [2]. not sure of how to reference the thread
Great! :-) I noticed an entry added to the how-to, but the actual
page [1] doesn't exist yet...?
To reference a thread, just copy a link from the archives [2]. While
using the official archives, the trick seems to be selecting the
desired thread or particular message and clicking on the Message
view link in order to get the desired thread/message hyperlink. In
this particular case, it would be [3].
As we're at it, given than navigation/search features are not very
user friendly in the official archives IMHO, I frequently use the
Nabble archive [4], specially for searches... ;-)
Hope this helps,

contribution advice?
Happy New Year Batikeers, I have a few enhancements I'd like to add to batik, but I'm not quite finished scoping/designing in that arena. In the meantime, I'm starting to absorb more of the core code. I find it usually helps me if I have a goal. Perhaps someone familiar with the current state of batik's bug list (Helder???) could point me toward some validated, higher priority bugs so that I might attempt to resolve? My Apache ICLA has been submitted and I do understand that I will be limited to submitting patches that may or may not be applied by an individual with commit access. Thanks, jonathan
Re: create a JSVGCanvas from an inputstream
Hi Dao,
Here are a couple of load routines I use frequently .. Hope they help you
narrow your problem.
Load from a file on the classpath (templated)
InputStream templateStream =
Canvas.class.getResourceAsStream(template.svg);
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
SVGDocument doc = null;
try {
doc = f.createSVGDocument(null, templateStream);
} catch (IOException ex) {
}
myCanvas.setSVGDocument(doc);
Load from a byte array version:
Element a = null;
ByteArrayInputStream bais = new
ByteArrayInputStream(myByteArray);
String parser =
XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
try {
a = f.createDocument(null, bais).getDocumentElement();
} catch (IOException ex) {
}
a = (Element) document.importNode(a, true);

The example uses direct setting of the x, y coordinates. Your example text
node has a transform attribute. You will likely need to transform the

transform=matrix(0.6881 0 0 -0.6881 142.5107 299.9995) style=

This use tag contains both an explicit x, y (-150,-200) and a transform,
you'll need to account for both in the rectangles positioning.
Furthermore, I am trying to replace the rect by a symbol reference. I
cannot succeed in modifying its aspect ratio. is there an attribute to
authorize this? To be more clear, I have drawn a nice rounded rectangle with
half opacity and decorations that I want to draw on top of the targeted node
(here horizon) with the same size.
From the spec...hoping it helps...
*If the 'use' element references a 'symbol' element:
In the generated content, the 'use' will be replaced by 'g', where all
attributes from the 'use' element except
for x, y, width, height and xlink:href are transferred to the generated 'g'
element. An additional
transformation translate(x,y) is appended to the end (i.e., right-side) of
the transform attribute on the
generated 'g', where x and y represent the values of the x and y attributes
on the 'use' element. The
referenced 'symbol' and its contents are deep-cloned into the generated
tree, with the exception that the
'symbol' is replaced by an 'svg'. This generated 'svg' will always have
explicit values for attributes width
and height. If attributes width and/or height are provided on the 'use'
element, then these attributes will be
transferred to the generated 'svg'. If attributes width and/or height are
not specified, the generated 'svg'
element will use values of 100% for these attributes.*
the targeted node could be a text, that's why my first posted you answered
with the bbox and the SVGLocatable.
The SVGLocatable/bbox method should work ok for any Element.

Re: Status of FlowRoot Overflow Detection?
Hi Brendan,
Without a complete example of the code, I'm guessing a bit here.
I have found that when dealing with text and bounding boxes you must be
careful to never try to obtain the newly added to the DOM text's bounding
box in the same worker.
To summarize:
urq.invokeLater(new Runnable() {
public void run() {
Text t = document.createTextNode(text);
textNode.replaceChild(t, textNode.getFirstChild());
...
SVGRect altbounds = locatable.getBBox();
}
});
Would likely fail because the text has yet to be rendered (hence the size
has not been calculated?)
You can easily get around this using 2 worker threads in succession.
Perform the Locatable bounding box operation in the second one:
urq.invokeLater(new Runnable() {
public void run() {
Text t = document.createTextNode(text);
textNode.replaceChild(t, textNode.getFirstChild());
}
});
urq.invokeLater(new Runnable() {
public void run() {
...
SVGRect altbounds = locatable.getBBox();
}
});
If I've missed the mark, please try to provide some additional information.

The Proposed Solution: Use the 'flowroot' element, check for overflow, and
iteratively adjust the font size of the text.
The Problem: Based on emails from this list dating from 2006, it does not
appear overflow events are implemented, and my alternative attempts to
formulate my own overflow detection mechanism have been unsuccessful.
The SVG:

font-family='Futura-Medium' font-size=72 id=titleflowLineSome
interesting text/flowLine/flowPara
/flowDiv
/flowRoot
/svg
---
While this code allows me to get the rectangle into which I'm flowing text:
---
SVGElement svgElement = (SVGElement) doc.getElementById(bounding);
SVGLocatable locatable = (SVGLocatable) svgElement;
SVGRect altbounds = locatable.getBBox();
---
but a similar call to attempt to get the bounding box for the laid out text
(I presume, I'm actually shooting in the dark at this point) results in an
uncaught exception:
---
SVGElement svgElement = (SVGElement) doc.getElementById(title);
SVGLocatable locatable = (SVGLocatable) svgElement;
SVGRect altbounds = locatable.getBBox();
---
Even if I move the id=title to the flowDiv, the result is the same. So
I'm at a bit of a loss.
Is there another, easier way to figure out the actual dimensions of the
laid out text in a flowDiv, or check the flowRoot for overflow? Or are
overflow events still not implemented?
Thanks in advance,

At this point I don't have the time to do development on Batik. Would the Batik 1.8pre team advise, augment and support a push to SVG 1.2 (current state)? I am supportive of Batik development (with the cautions above). I'd be happy to provide guidance/suggestions as wanted/needed.
Affine Transform Utility Class
For all of those new (and possibly old) to Batik, especially those that don't want to fret about transforms. Please advise if this already exists and the reference should point elsewhere: An element level wrapper for AffineTransformations - http://wiki.apache.org/xmlgraphics-batik/TransformUtil Thanks to the core team for all the great work!

Batik momentum
I realize this topic comes up from time to time and I think we all just muse until the current crisis passes. Is Batik headed to w3c svg 1.2+? I consider Batik to be the bleeding edge of SVG. Yes, I am often taunted in front of jeering adobe crowds...but they cannot flash what I can batik I realize that the current team is focused on other corporate, personal and technological challenges. This is normal. I need Batik 1.2 and beyond. I will soon be implementing 1.2+ functionality simply because we need it and it does not exist. I wonder how many others are at this cusp? I'm willing to help and the effort will positively impact my employer. I want to apache commit and will start the process tonight, but I need help... How many others would possibly backfill a 1.2 functionality push. Would the Batik 1.8pre team advise, augment and support a push to SVG 1.2 (current state)?

I'm not sure where the javadoc is, but the spec will get you far here: http://www.w3.org/TR/SVG/types.html#BasicDOMInterfaces good luck!

Hello,
I want to register some mouse events on an SVG element. Where can I find
the list of events I can register? I can find samples with
EventTarget etr = (EventTarget) elt;
etr.addEventListener(click,*
new*org.w3c.dom.events.EventListener() {
but what are the other event types ? For example, I want to register a
mouse hover to highlight an element of the SVG

Re: Issue in setting the canvas size( Mouse click not active in whole area of the applet)
Hi Shekhar, If I understand correctly, you have 1 (or more) elements on the canvas and you would like to highlight the clicked one and unhighlight when the background is clicked. The below assumes that... One method is to add a glass pane to the canvas in order to capture the off events. Add a g behind all other elements. ensure that the g tag pointer-events=all or other (see http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty) Add a listener for the g you'll have to manage the event bubbling with this method, but it is pretty easy to implement Hope this helps, Jonathan On Tue, Sep 8, 2009 at 9:02 AM, Shekhar Bhati shekhar.bh...@gmail.comwrote: Can anyone suggest something regarding below mentioned issue with batik?

The issue is when an object is highlighted then only between a fix area only the unhighlighting is working. Even when i try to track the mouse click action then also it is not able to sense the click event beside that particular area.. Is it the problem of canvas size?

Re: Issue in setting the canvas size( Mouse click not active in whole area of the applet)
Corrections... use a rect instead of a g for the glasspane and ensure it covers the entire svg/viewBox sorry for the confusion On Tue, Sep 8, 2009 at 1:47 PM, jonathan wood jonathanshaww...@gmail.comwrote: Hi Shekhar, If I understand correctly, you have 1 (or more) elements on the canvas and you would like to highlight the clicked one and unhighlight when the background is clicked.
