OK, thank's (so fast!!!) -----Message d'origine----- De : Bishop, Michael W. CTR USJFCOM JFL [mailto:[email protected]] Envoyé : mercredi 2 septembre 2009 17:11 À : [email protected] Objet : RE: transform attribute marshaller
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.

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...)? -----Message d'origine----- De : Bishop, Michael W. CTR USJFCOM JFL [mailto:[email protected]] Envoyé : mercredi 2 septembre 2009 16:35 À : [email protected] 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. Michael Bishop -----Original Message----- From: HODAC, Olivier [mailto:[email protected]] Sent: Wednesday, September 02, 2009 10:04 AM To: [email protected] 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)); } }); } Olivier Dao Ho Dac Flight Test Software Architect Airbus France - EVIDA Phone : + 33 (0)5 67 19 81 34 Fax : +33(0)5 61 93 80 02 Mailto:[email protected] The information in this e-mail is confidential.
