I think you want the org.apache.batik.parser.AWTTransformProducer.createAffineTransform(...) method. Getting it back to the transform="matrix(...)" is messier. I used AffineTransform.getMatrix() and MessageFormat to put it back into the element.

I was more interesting in finding a way to retrive the transform attribute and modify this without having to parse the string myself.. transform="matrix(1 0 0 1 349 384)".. i do not really consider it the best idea to do this parsing myself if there exisits a method which allows me to do for instance do somthing similar to pseudocode: Transformation t = Transformation.getMatrixObject(String matrixString); double x = t.getTranslateX(); t.setTraslateX(x+40); element.setAttribute(SVGConstants.SVG_Transform_Attribute,t.getString()); On Tue, Jun 3, 2008 at 12:49 PM, Guillaume Rosauro <[EMAIL PROTECTED]> wrote: Hi, You can retrieve all elements from the SVG file like any other XML file. So getElementById or something like that should be sufficient. Guillaume On Tue, Jun 3, 2008 at 12:37 PM, Lars Eirik Rønning <[EMAIL PROTECTED]> wrote: Hi. Is there an easy way for me to retrieve the affine transformation such as an element's matrix from an exisiting svg file and alter only the translation aspect of the matrix? I was hoping i could get this as a string attribute and then have a object which allowed me to extract the values i wanted without having to parse the string.. When the values are altered i would like to insert this back as a string into the svg file. Thanks Lars
