The effect you describe is well known. In fact, we discussed about it many years ago and decided to leave it like it is. The problem is that the true bounding box of a picture does depend on both the paths and the respective linewidth. It is simple to calculate bounding boxes for lines; for curves it is more difficult. PyX calculates these two. Including also the linewidth and stroke effects coming from the different linejoin parameters is really difficult. We decided not to do this, as it would lead to a reimplementation of ghostscript. This is why canvas.writeEPSfile and the equivalent for PDF take a parameter "bboxenlarge". This is meant to serve as a workaround for the above problem. It is set to 1pt by default. As you increased the linewidth to 1cm, you should play also with this parameter. You may also use ghostscript to calculate the true bounding box: gs -dNOPAUSE -q -dBATCH -sDEVICE=bbox Michael -- Michael Schindler Laboratoire de Physico-Chimie Théorique.
