Anyhow, I've just completed a simple code module that converts Cairo paths to and from Clipper's polygon storage class (a c++ std::vector class) making it very easy to use Clipper with Cairo. If anyone is interested, here are a couple of links to my cairo-clipper module and a small demo utility: <a href="http://angusj.com/delphi/">C++ version (compiled with C++Builder): http://www.angusj.com/delphi/</a>cairo_clipper_cpp.zip Delphi version: <a href="http://angusj.com/delphi/">http://www.angusj.com/delphi/</a>cairo_clipper.zip Finally, while I'm an experienced Delphi developer, I've had relatively little experience with C++ so I welcome feedback/suggestions if this can be done more elegantly.
