Dear Boost Users, I am getting started with boost.python. I want to port an image processing library into python. My problem is, that I have several pixel types (like int, float, etc.) which I'd love to handle in the same object by downcasting. In c++ it's something like this: class image {}; class float_image : image { float * pixels; // or boost::array_ptr<float> } class int_image : image { int * pixels; // or boost::array_ptr<int> } I can create the image object by: image * A = new float_image() image * B = new int_image() Now I'd have a virtual functions virtual float image::get_element() virtual int image::get_element() obviously this won't pass in c++, but in python it should pose no difficulty, as python uses dynamic casting. Is there a manner to do this with c++/boost/python? thank you for considering, Laszlo
