Thanks michael
If I understand well, I create a new affineTransform from the attribute
transform string using the static method
AffineTransform at = AWTTransformProducer.createAffineTransform(String s)
Then, I use the setters from the AffineTransform to set the rotation value,
etc...
Finally, I use the standart java MessageFormat stuff to marshall it? You mean
that I explicitely write:
MessageFormat.format("matrix(%f %f %f %f %f %f)", at.getScaleX() , etc...)?

Objet : RE: transform attribute marshaller
Hello,
I use Batik's AWTTransformProducer to go from a "transform" attribute to
an AffineTransform. I manipulate the AffineTransform however I need to,
then use the MessageFormat class to write out the "transform" attribute
with the 6 values of the matrix. I haven't found a better way to
produce the "transform" attribute, but I find manipulating an
AffineTransform to be easier to work with.
I don't know how familiar you are with transforms, but you might want to
search this list for "AffineTransformUtil" if transform operations don't
work the way you "expect" them to with cumulative updates.

Subject: transform attribute marshaller
Hello,
I am totally newby with batik and I am wondering if I am thinking right.
I have seen that there is some parsers that are used with handlers. Butr
here is my requirement:
I want to change dynamically in java the position and some attributes of
my initial svg file. I am focussing for the moment on the transform
attribute (to move and rescale my object) and the fill attr ( to change
the color)
I am doing the following. You can see that I have to create the whole
transform value string each time (I could have used the format method,
by the way) by hand
Is there a way to do that with some ready to use classes (ex:
TransformableElement.setTransform(X_POS, value)) ?
protected void setSize(double d) {
getElt().setAttributeNS(null, "transform", "matrix("+d+"
0 0 "+d+" 243.3438 143.687)");
}
getSvgCanvas().getUpdateManager().getUpdateRunnableQueue().invokeLater(n
ew Runnable() {
public void run() {
setSize(theNewSize));
}
});
}
