byte containers
by Leonardo Rochael Almeida Oct. 3, 2002

I'm officially working with the TerraLib mantainers (http://www.terralib.org/) to make Python bindings for it (Dave, you can count this one as another boost.python project :-). Part of the functionality of that library concerns map tiling: large geo-referenced images are sliced and the tiles are stored in a Database. Later on, you can ask the library to return the map of an area and it will reassemble the image and return it. What is the best way to pass a lump of bytes (with nulls in it) back and forth? Something that I could get as a Python String would be nice, but std::string doesn't seem null friendly... Ultimately I'll probably be feeding this lump of bytes to PIL (Python Imaging Library) to make some final tweaks to the image before publishing it on the Web (it's actually a Zope project). Any tips? -- Ideas don't stay in some minds very long because they don't like solitary confinement.

char '\0' -> "\0" or ""?
by Ralf W. Grosse-Kunstleve Oct. 1, 2002

Consider char foo() { return '\0'; } def("foo", foo); Python with Boost.Python V1: foo() == "" Python with Boost.Python V2: foo() == "\0" Is this difference intentional? I'd prefer the V1 result. Opinions? Thanks, Ralf __________________________________________________ Do you Yahoo!? Yahoo! News - Today's headlines http://news.yahoo.com

However, on a related issue, I'd definitely like to see <boost/python/detail/wrap_python.hpp> moved up out of detail. It's useful in its own right if you're embedding and neither including a "detail/" header directly nor including an arbitrary public header to get at it are very elegant. best, Greg -----Original Message----- From: David Abrahams [mailto:dave@boost-consulting.com] Sent: 01 October 2002 14:09 To: pysig Subject: [C++-sig] Boost.Python v2: A few small changes [...]
