Hi Mike, Thanks for the answer. I'll check the code. For the moment png or jpeg is ok, but maybe in the future i'll like to save the image as postscript to use it with LaTeX font and so on. I've se the gl2ps library and the last version is 21 September 2004. Can you send me the SWIG file? I don't know much about swig and it would be easier to start with a file that has work in same older version.
