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));
}
});
}

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.

Yes, except for at.getScaleX(), I do:
double[] matrixValues = new double[6];
matrix.getMatrix(matrixValues);
Then I use matrixValues[0 - 5] to populate the "matrix" part of the "transform" attribute.
Although, reading the Javadoc, I guess it doesn't matter. You could use:
getScaleX(), getShearY(), getShearX(), getScaleY(), getTranslateX(), and getTranslateY() in that order to get the same values.
Either way, it's a little tedious, but it works.

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...)?

If you check out the SVG DOM there are interfaces to get the
transform list associated with an element. Note that, at least
in Batik, everything is still based on the DOM String so we will
effectively do what you are doing.
Something like:
((SVGTransformable)
getElt()).getTransform().getBaseVal().getItem(0).setTranslate(x, y);
The getItem is needed because it tracks 'complex' transform attributes.
This can be useful as it would allow you to keep your scale transform
independent
of the translate (otherwise you may need to multiply your transform values
by the
scale values).
