Hi Dominik, i have found my failure. My next Question is it is possible to generate a SVG Document that only contains the svg code from the clipping path. The main Problem is i have tree JSVGCanvas in the first i show the hole map in the second a part of this map (like a district) and in the last i show only a special point of the map. The problem is when i have a svg File that is 1Mb big the batik needs 600 Mb Memory and the system works very slow. Have anybody a idea to solve this problem.

Does anyone have an idea about how to do this using the Batik toolkit ?
