Yes, of course there is. What you get by calling getViewBoxTransform() is the current Transformation Matrix, Batik uses to do the Transformation from world coordinates to screen coordinates. You can do something like this: AffineTransform affTrans = myCanvas.getViewBoxTransform(); affTrans.transform(point1,point2) //where point1 and point2 are some Point2D and you get the screen coordinates from the world coordinates that are stored in point1 as result in point2. If you want to do it the other way round (screen coordinates to world coordinates), you need to use the inverse of the Transform Matrix, which you get by affTransInv = affTrans.createInverse(); I hope that I remembered all of this correctly... :-) Kind regards, Kai. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
