Hi, Quadratic Bézier curves can easily be drawn using cubic Bézier curves, see wikipedia: http://en.wikipedia.org/wiki/Bezier_curves#Terminology For elliptical arcs, here is the algorithm used by Firefox to approximate them: http://www.spaceroots.org/documents/ellipse/elliptical-arc.pdf http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/src/gfxContext.cpp#803 HTH, F.
